Pruning is essential to maintaining the health of our Kelowna trees and consequentially pruning  trees helps the health of our local birds; however it is equally critical to prune correctly and at the right time. In this article we delve into the why, when and how of fall pruning once the nesting season is finished. But first, we’d like to touch on how to create a bird sanctuary in the urban environment.

Creating an Urban Bird Sanctuary with Trees and Hedges

Trees and other flora such as bushes and hedges are vital for healthy bird populations. A decrease in habitat is one of the main reasons for the decrease of our bird population, and urban areas are a major contributor to the decrease of habitat. Urban areas pose other risks to birds as well: our use of pesticides, our cats and our buildings full of windows all hurt birds. Luckily we can mitigate some of these threats by taking care of our residential gardens and green spaces. Trees, bushes and hedges provide a number of benefits for birds: security from predators, a safe place to nest as well as being a prime food source, both from fruits and seeds as well as from the insects this flora attracts.

Go Native Whenever Possible

The best trees, bushes and hedges to increase our native bird population are native ones; our local birds have co-evolved with our native flora as their food source and shelter, making them eminently suitable to our local birds. Local birds are genetically in tune with native flora; they know when native trees flower, fruit and shed leaves, and they automatically synchronize their life cycles and migration patterns to the flora’s life cycles. A few examples of Kelowna area native trees that attract birds are: Pacific Dogwood, Poplar, Willow and Serviceberry.

Growing Bird Corridors

City hedges create bird corridors by forming a chain of connected, native vegetation that provides food, shelter, and nesting sites for birds and other wildlife. At their best, hedges provide a green network that links the more substantial green spaces, allowing birds to move safely between them. Hawthorn, Hazel and Oregon Grape are Kelowna native species that make great hedges.

How Pruning Maintains Tree and Hedge Health

With a diversity of native trees and hedges, we’ve already set the foundation for protecting our birds. Pruning is an essential maintenance practice to promote the health of your bird sanctuary.   

Pruning helps maintain the health of your trees and hedges by:

• Increasing pest control by removing dead, diseased and damaged branches
• Improving growth by directing nutrients to healthy branches
  Improving air flow and light, for increased photosynthesis
• Increasing structural strength
• Increasing flower and fruit production

Pruning increases the health of our trees and hedges which in turn will boost our nesting bird population; however pruning at the wrong time can seriously damage our birds’ ability to produce young.

Regulations Protecting Bird Nests

In fact, there are both federal and provincial regulations (federal Migratory Birds Convention Act and the provincial Wildlife Act) that aim to protect migratory birds by prohibiting their nests from being damaged or disturbed when they contain a live bird or viable egg. 

The nesting season in BC varies with each species; however, it generally lasts from March 1 to August 31. That leaves the beginning of September to the end of February for pruning.

Fall Pruning: When and How

While most plant pruning is best undertaken in the spring to stimulate growth, fall tree pruning has benefits and may even be preferred in some cases.

The time to prune your tree in the fall is once the leaves have dropped. This signifies that the tree has gone dormant. Conifers also go dormant which is apparent by a lack of new growth and when its buds are set. Reasons to prune in the fall are:

• Better Able to See the Tree’s Structure: Once the leaves have fallen, it is easier to see the structure of the tree and what branches need to be removed.
• Preparation for Spring Growth: Fall pruning clears away dead branches, not only removing a possible danger of branches failing under the weight of snow in winter, it also enables the tree to kick start growth in the spring instead of focusing on healing spring pruning cuts.
• Controls Disease and Pests: Removing diseased or pest infested branches in the fall decreases the chance of the disease spreading.
• Less Stressful: Trees go dormant in the fall, so pruning is less stressful. For some trees, particularly ones that bleed in the spring, such as maple or cherry, fall pruning is a must.

Fall Pruning is Best Left to the Professionals

Fall pruning post nesting season can be extremely beneficial for the health of the tree, however, it can also be tricky. It must be done with a high degree of knowledge to remove only what needs to be removed, and only when the tree has gone dormant. Professional arborists are also careful to avoid bird nests. Even if the birds have finished nesting for the year, many species return to reuse the same nest. For fall pruning especially, it is best left to professionals. If you live in the Kelowna area and you need help, give Action Tree a call.

In this article we delve into the types of summer storm damage a tree can suffer, and how the tree can be helped to heal if it isn’t too badly damaged.

How Summer Storms Can Damage Trees

A summer storm can include a mix of wind, heavy rain, lightning or hail. Any of these elements, on their own or in combination, can damage a tree.

Common issues after a summer storm are:

Broken branches, limbs and foliage damage: Wind, hail and even heavy rain can snap branches leaving them hanging precariously. This sort of damage is more frequent in trees with a dense crown, but can happen to any tree. Not only does this pose a safety risk to people and property, it can also negatively impact the structure, and thus the health of the tree. As well, strong wind and hail can strip or shred the leaves and needles from a tree, decreasing its ability to photosynthesize and receive the nutrients and energy it needs for health.

Leaning or uprooted trees: The Okanagan often experiences periods of drought in the summer, which can make trees more vulnerable to wind damage, especially when combined with the heavy rains of a summer storm. In a drought, the roots of a tree can start to die off, weakening the tree. The heavy rains of a summer storm can then quickly saturate the soil, reducing the soil’s ability to anchor the tree’s roots. Under these conditions, a strong wind can more easily topple a tree, especially one with a shallow root system.

Damage to a tree’s structure:

Trees with a particularly dense tree canopy are vulnerable to structural damage in a strong wind — especially if the canopy is very heavy due to rain, Wind will not easily flow through a dense tree canopy and a strong wind can move this dense tree canopy in a way which can, in turn, move the root plates of the tree, causing a twisting or bending that can leave cracks and splits in the tree’s trunk. If it is bad enough, this can make the tree unstable and more prone to falling over. Cracks or splitting can also provide entry points for disease or insects.

If lightning directly strikes a tree, the extreme heat can boil the water within the tree’s cells, causing an explosion that can spit the tree’s trunk, leave burned grooves in the bark or completely shatter the bark. Even if there does not seem to be much external damage, the tree could have suffered internal burning and damage and must be checked out by an arborist.

Tree Pruning, Trimming, Cabling & Bracing are the Ideal Fixes for Storm Damaged Trees

If your trees have been damaged in a summer storm, the first step is to call a certified arborist to evaluate the extent of the damage and determine the best course of action for restoration. The arborist will also assess the hazards, such as hanging branches, fallen trees, proximity to buildings or power lines, and will organize for professionals to safely remove the threats.

In many cases, expert tree pruning, trimming, cabling or bracing, and possibly some bark and tree wound repair, are all that are needed to help a tree back to health and to stabilize it. However, unfortunately, sometimes the best course of action is tree removal. 

Tree Trimming and Pruning

If the storm damage is mostly limited to the tree’s crown, and is less than 50% of the crown, there is a good chance, under the guidance of an ISA certified arborist, that the tree can be saved. At Action Tree we remove the heavily damaged and dangerous branches and limbs and then prune or trim to work on branching patterns for healthy regrowth and stronger resilience to future storms.

How pruning and trimming helps a tree back to health after storm damage: 

• Removes the danger of further damage from falling branches
• Reduces wind resistance, greatly reducing branch breakage, as well as twisting and bending of the structure in a strong wind
• Prevents disease and decay, by removing the damaged areas and thus the entry points for disease or insects
• Balances and improves the tree’s structure so the tree is more resilient in future storms
• Promotes growth by getting rid of damaged parts that can sap a tree’s energy

Tree Cabling & bracing

If the damage to the tree involves structural weakness within the canopy or trunk, the arborist might suggest support through cabling and bracing. These methods will distribute the weight to prevent further damage. 

Cabling involves strategically installing steel cables in the tree’s canopy to support weaker branches so they don’t snap or split under their weight or in a wind. Bracing involves inserting metal rods into the trunk or branches or using other hardware to reinforce areas where there are cracks or splits to prevent further damage and allow for healing.

Cabling and bracing are powerful measures, and they must be done by an expert and inspected regularly. If cables or braces are improperly placed they can strangle (girdle) a tree or cause other structural problems.

How Cabling and bracing can help a tree back to health after storm damage:

• Increases resilience to winds and storms, minimizing the potential for further damage
• Increases the chance for limbs to heal since they will be less likely to be stressed or to break
• Increases the lifespan of a weakened tree
• Avoids tree removal in some cases

Are Your Trees Suffering From Summer Storm Damage?

The good news is that in many cases, a tree can be nursed back to health after summer storm damage. A plan of action could involve tree pruning, trimming, cabling, bracing or other tree care measures depending on the arborist’s diagnosis. In some cases a dangerous tree will need to be removed.

Summer storm cleanup can be risky. Often branches or whole trees have or are about to fall on live wires, buildings or other trees. Action Tree is highly experienced with these sorts of circumstances, and has all the necessary equipment to handle even the most hazardous situation involving a tree.

Nursing a storm damaged tree back to health takes a great deal of knowledge and expertise. If the problem is not diagnosed correctly or the solutions are not applied properly, the tree might not make a full recovery.

If your trees were damaged in a summer storm, give us a call. We can restore them to their vibrant health and beauty. 

Lilac Trees in Kelowna

As arborists at Action Tree Service in the picturesque city of Kelowna, BC, we have the pleasure of working with a variety of beautiful trees that thrive in our unique climate. One of the most enchanting and popular among our clients is the lilac tree. Famous for its vibrant blooms and sweet fragrance, the lilac can be a stunning addition to any landscape. However, maintaining these delicate trees in Kelowna’s sometimes harsh summer heat requires specific care. In this blog, we’ll share some of the wisdom we’ve garnered over the years on how to keep your lilac trees flourishing even during our warmest months.

Understanding Lilacs

Before diving into care techniques, it’s important to understand a few basics about lilacs. These deciduous trees are known for their lovely spring flowers and sweet aroma. They typically bloom in late spring, though some varieties can flower in early summer. Lilacs generally prefer cooler climates, but they can adapt to warmer temperatures if cared for properly.

Selecting the Right Lilac

Choosing the right lilac variety can make a big difference in how well it will thrive in Kelowna’s climate. Some species are more heat-tolerant than others. The common lilac (Syringa vulgaris) and the Persian lilac (Syringa x persica) are popular choices that are known for their adaptability and hardiness. When selecting a lilac, consider its mature size and bloom time to ensure it fits well with your garden’s layout and your desired aesthetic.

Planting Your Lilac

Any tree’s success often begins with its planting technique. To give your lilac the best start:

• Timing: Plant lilacs during the cooler months of fall or early spring to avoid the summer heat stress.
• Location: Choose a spot where the tree will receive at least 6 hours of direct sunlight daily. To bloom profusely, lilacs need plenty of sun.
• Soil: Lilacs prefer well-drained, slightly alkaline soil. Before planting, amend the soil with compost to improve its structure and fertility.
• Spacing: Ensure there is enough space between your lilacs and other plants. This promotes good air circulation, which is crucial in preventing fungal diseases.

Watering Practices

Proper watering is crucial, especially during Kelowna’s hot summers. Consistency is key. Water your lilacs deeply but infrequently to encourage deep root growth, which helps the tree access moisture even during dry spells.Apply a layer of organic mulch around the base of your lilac to help retain soil moisture and regulate soil temperature. Using a soil moisture meter or check the soil manually to ensure it’s moist but not waterlogged.

Fertilising and Pruning

Lilacs do not require heavy fertilisation, but they do benefit from the right nutrients. Use a balanced fertiliser in early spring to promote healthy growth and flowering. Avoid high-nitrogen fertilisers, as they can lead to excessive green growth at the expense of blooms. Prune lilacs right after they bloom to shape the tree and remove spent blooms. This helps the tree focus its energy on next year’s flowers rather than seed production. Remove any dead or diseased branches to maintain the tree’s health and appearance.

Pest and Disease Management

Even with the best care, lilacs can be susceptible to pests and diseases, especially in a climate as variable as Kelowna’s.Common pests like lilac borers and scale can be managed through regular inspections and, if necessary, the use of appropriate insecticides.

Prevent Diseases: Powdery mildew is a common fungal issue, particularly in humid conditions. Ensure good air circulation and consider fungicidal treatments if the problem persists.

Not just about blooms

Caring for lilac trees in Kelowna’s summer heat can be a rewarding endeavor. With the right knowledge and a bit of dedication, these beautiful trees can thrive and bring years of beauty and fragrance to your garden. At Action Tree Service, we’re committed to helping our community’s landscapes look their best. Whether you need advice on plant selection or professional care for your existing trees, contact us, we’re here to help. Remember, a healthy lilac is not just about blooms; it’s about creating a vibrant ecosystem in your own backyard.

Happy gardening from all of us at Action Tree Service!

Nestled in the heart of British Columbia, the Okanagan Valley is renowned for its stunning landscapes and dry, sunny climate. While the region boasts perfect conditions for vineyards and orchards, the typically low precipitation levels present unique challenges for landscaping. As water conservation becomes increasingly important, selecting drought-tolerant trees is a smart choice for sustainable gardening. In this blog, we’ll explore three of the best drought-tolerant trees for the Okanagan region, along with tips on how to water them effectively.

1. Ponderosa Pine
(Pinus ponderosa)

Characteristics: The Ponderosa Pine is a majestic, towering tree that is well-adapted to the dry conditions of the Okanagan. Known for its thick, scaly bark and long, slender needles, it not only provides substantial shade but also adds a robust, rustic charm to any landscape. Its deep root system allows it to access water from deeper soil layers, enhancing its drought tolerance.

Ideal for: Large yards, parks, and naturalized areas where it can grow without constraints.

Watering Recommendations:

• Establishment Phase: For the first few years after planting, water your Ponderosa Pine deeply once a week during the hottest months to encourage deep root growth. Each watering session should moisten the soil to a depth of about 12-18 inches.

Mature Trees: Once established, Ponderosa Pines require minimal additional watering. Natural rainfall in the Okanagan is typically sufficient, but during prolonged dry spells, monthly deep watering may be beneficial.

2. Blue Atlas Cedar
(Cedrus atlantica ‘Glauca’)

Characteristics: The Blue Atlas Cedar is a striking tree with silvery-blue needles and a dramatic, spreading form. This cedar is not only a visual standout but also highly resistant to drought once established. It thrives in full sun, reflecting heat with its shimmering needles, which helps it conserve moisture.

Ideal for: Accentuating corners of large properties, focal points in garden designs, or alongside driveways where it can grow without obstructing views.

Watering Recommendations:

• Establishment Phase: During the first growing season, water the tree weekly, ensuring that water reaches 8-10 inches deep to foster a strong root system. In the hottest parts of summer, additional watering may be needed.

Mature Trees: After the first year or two, gradually reduce watering frequency. Mature Blue Atlas Cedars are very drought tolerant and generally require watering only during extended periods of drought. Checking the soil moisture periodically can help guide whether additional watering is needed.

3. Kentucky Coffee Tree
(Gymnocladus dioicus)

Characteristics: The Kentucky Coffee Tree is a unique and underused landscape tree with rough bark and large, compound leaves that provide dappled shade. This tree is particularly noted for its tolerance to a wide range of soil types, including dry, compacted, and alkaline soils. It loses its leaves early in the fall, which minimizes water loss during the critical late summer months.

Ideal for: Urban gardens, street plantings, and open landscapes where its distinct form and leaf texture can be appreciated.

Watering Recommendations:

• Establishment Phase: Water every 7 to 10 days during the first growing season. Ensure that each watering saturates the soil to at least 10 inches deep, promoting good root development.

Mature Trees: Kentucky Coffee Trees are extremely drought-resistant once established. Watering once a month during extremely dry conditions can support tree health, but often, this tree will thrive on rainfall alone, requiring no additional irrigation.

Thrive Under the Region’s Arid Conditions

Choosing drought-tolerant trees for your Okanagan property not only conserves water but also ensures that your landscape can thrive under the region’s arid conditions. The Ponderosa Pine, Blue Atlas Cedar, and Kentucky Coffee Tree each offer unique aesthetic qualities and practical benefits, making them excellent choices for both ornamental and functional uses in dry climates. By understanding and implementing the right watering practices, you can support these trees in their younger years and watch them grow into resilient, mature specimens that enhance your landscape while aligning with sustainable gardening practices.

Remember, even drought-tolerant species need careful attention during their establishment phase. Proper early care ensures that these trees develop a robust root system capable of withstanding the dry conditions characteristic of the Okanagan Valley. Happy planting and enjoy the beauty and benefits of these remarkable trees in your sustainable garden.

What is Wildfire Resilience

The ability to withstand wildfires and their negative effects is referred to as “wildfire resilience.” It includes a variety of tactics and strategies meant to lessen the negative impact on populated communities’ susceptibility to wildfires and lessen the damaging effects of these natural occurrences.

Kelowna’s Susceptibility To Wildfires

The City of Kelowna, though a beautiful lakeside city, is unfortunately susceptible to wildfires. Kelowna and most of the Okanagan Valley, which are situated in close proximity to coniferous forests and grasslands, are at greater risk because wildfires are able to spread from these natural areas into populated areas. Coniferous forests, or chaparral, are more susceptible to wildfires. Accumulated dead and dry vegetation, referred to as “fuel,” feeds wildfires. In addition to Kelowna’s proximity to forests and grasslands, the city’s summer weather is hot and dry. These extended periods of drought, usually experienced every summer, create the environment in which wildfires occur.

Why are Wildfire’s Necessary for Forests

In many forest ecologies, wildfires are a crucial ecological event essential to the lifecycle of forested areas. Wildfires play a number of crucial roles in preserving the wellbeing and operation of these ecosystems. Wildfires remove dead vegetation and overgrown underbrush and manage disease and pest outbreaks. They aid in the renewal and rejuvenation of forests, which allows for new growth to occur.

Fires return organic debris and nutrients held in plants to the soil. Because it refills the soil with key nutrients that enable plant growth, this nutrient cycling is essential for the wellbeing of forest ecosystems.

With dead vegetation and overgrown underbrush removed, wildfires lessen competition for resources like sunshine, water, and nutrients among the remaining trees and result in stronger, healthier forest stands. However, wildfires become a problem when they pose a threat to or pose dangerous risks to human communities.

Improving Wildfire Resilience on Your Property

Manage your property by first identifying ignition zones. Ignition zones are specific areas around a property that are evaluated for their vulnerability to ignition during a wildfire. Managing ignition zones is a critical aspect of wildfire resilience, as it involves implementing measures to reduce the risk of a wildfire starting on or spreading to your property. Ignition zones are categorised into three zones, each with its own set of recommendations for mitigation:

Zone 1: Immediate Zone 0-1.5 Metres

• This is the area closest to your home, typically within 0 to 1.5 metres from structures.
• The focus in this zone is to create a “defensible space” that is highly resistant to ignition.
• Completely remove dead vegetation, brush, trees, leaves, and any other potential fuels for wildfire.
• Use non-combustible materials for landscaping and building features.
• Ensure proper spacing between trees and shrubs to prevent fire from spreading from vegetation to structures.
• Remove coniferous trees in this zone.

Zone 2: Intermediate Zone 1.5–10 Metres

• This area extends from 1.5 to 10 metres out from structures.
• Reduce the density of vegetation, trees, and brush to slow the spread of fire.
• Create spacing between trees and shrubs to reduce the risk of crown fires.
• Maintain trees and shrubs through pruning and thinning.
• Consider using fire-resistant plants in your landscaping.
• Remove coniferous trees, and instead plant deciduous (leafy) trees, which are more resistant to wildfires.

Zone 3: Extended Zone 10–30 Metres

• This is the area from 10 to 30 metres from structures.
• Focus on creating a well-maintained landscape that reduces the overall fuel load.
• Thin and space trees to prevent the spread of fire and promote healthier forest stands.
• Remove all dead and diseased trees.
• Maintain a fire-resistant perimeter by mowing grass and clearing brush, reducing dense underbrush.

The Impact of Winter Storms on Trees

Heavy snowfall can burden even the healthiest of trees, causing branches to snap under the weight. High winds, which often accompany winter storms, can wreak havoc by breaking limbs, stripping bark, or even toppling entire trees.

Common issues seen after winter storms in Kelowna include:

• Fallen Branches and Limbs: Snow and ice accumulate on branches, weighing them down until they snap.
• Uprooted Trees: Saturated or frozen ground combined with strong winds can destabilize root systems, causing trees to fall.
• Hanging Branches (“Widowmakers”): Broken branches that remain lodged in trees pose a serious safety hazard, as they can fall without warning.
• Damaged Tree Structures: Splits, cracks, or broken trunks can destabilize trees, making them unsafe to leave standing.

These hazards can damage homes, vehicles, and power lines, as well as create dangerous conditions for people walking near or beneath damaged trees. Addressing these issues promptly is essential, but storm cleanup is no small task, especially when dealing with large trees or debris in hard-to-reach areas.

As winter approaches in Kelowna, BC, residents prepare for the inevitable onslaught of snow, ice, and high winds. While many focus on clearing gutters and winterizing homes, one crucial aspect often overlooked is the condition of trees on their property. Heavy snowfalls and fierce winds can turn seemingly stable trees into dangerous hazards. For homeowners, it’s essential to assess and identify potentially dangerous trees before winter arrives to prevent damage to property and ensure safety.

At Action Tree Service, we specialize in dangerous tree removals using mobile cranes, making us experts in identifying risks and providing solutions. In this guide, we’ll discuss the types of trees common in Kelowna, how they can become hazardous in winter, and how to spot warning signs before the cold season sets in.

Types of Trees in Kelowna and Their Winter Challenges

Kelowna’s diverse landscape is home to many tree species, including evergreens like Douglas fir, ponderosa pine, and spruce, as well as deciduous trees like maple, aspen, and cottonwood. Each type of tree has its own unique strengths and weaknesses when it comes to withstanding winter storms.

Evergreens (Douglas Fir, Ponderosa Pine, Spruce)

• Strengths: Evergreens are generally more resistant to heavy snowfalls because they retain their needles, which help disperse snow weight. Their wood is also dense and strong, giving them some resilience against wind.
• Weaknesses: Despite their advantages, evergreens can still become hazardous during winter, particularly if they have structural issues like dead or broken branches. These trees are also vulnerable to uprooting during strong wind events, especially if their root systems are shallow or weakened.

Deciduous Trees (Maple, Aspen, Cottonwood)

• Strengths: These trees shed their leaves in the fall, which reduces the surface area exposed to wind and snow. Without heavy foliage, they are less likely to collect snow on their branches.
• Weaknesses: Deciduous trees, especially those that are older or suffering from disease, can become brittle and prone to branch failure. Cottonwoods, in particular, are notorious for dropping large limbs, even in moderate wind. Their rapid growth often leads to structural weakness, making them a higher risk during winter storms

Common Tree Damage that Can Become Hazardous in Winter

Certain types of tree damage pose a greater threat when winter weather arrives. Recognizing these problems early can help you avoid accidents or property damage. Here are some key issues to look for:

1. Dead or Dying Branches

Dead branches are one of the most common hazards to watch out for. These branches are brittle and can easily snap under the weight of snow or in strong winds. They can fall without warning, causing damage to nearby structures or vehicles, and posing a danger to anyone below.

What to Look For:

• Branches with no leaves or needles during the growing season
• Bark that is peeling away or has fallen off
• Branches that sound hollow when tapped

2. Cracked or Split Trunks

A tree trunk with a visible crack or split is a serious concern. Cracks weaken the structural integrity of the tree and can cause it to fall under pressure. In some cases, a crack might develop slowly, but winter’s heavy snow or ice can exacerbate the problem, leading to a full tree collapse.

What to Look For:

• Vertical splits or cracks running along the trunk
• Deep grooves or cavities in the trunk
• Fungal growth, which may indicate internal decay

3. Leaning Trees

While some trees naturally grow at an angle, a tree that suddenly starts to lean more than usual is a red flag. Leaning trees are often a sign of root instability or trunk damage, making them particularly vulnerable to falling in high winds.

What to Look For:

• A noticeable increase in the angle of the tree’s lean
• Exposed roots on the side opposite the lean
• Cracks or buckling in the soil around the base of the tree

4. Weak or Decayed Roots

The root system is the foundation of a tree, and if it’s compromised, the tree can topple over, especially during a winter storm. Tree roots can decay due to poor soil conditions, pests, or diseases. In some cases, construction or landscaping work can also damage roots, making them weak over time.

What to Look For:

• Mushrooms or other fungi growing at the base of the tree (a sign of rot)
• Soil upheaval or exposed roots
• A history of recent construction or soil compaction near the tree

5. Overgrown or Heavy Limbs

Even healthy trees can become dangerous if they have overly long or heavy branches that stretch too far from the trunk. Snow can easily accumulate on these limbs, weighing them down and increasing the likelihood of breakage.

What to Look For:

• Branches that extend far beyond the tree’s center
• Limbs that hang over structures, driveways, or power lines
• Thick, dense canopies that may trap snow and ice

Preparing for Winter: When to Call Action Tree Service

If you notice any of the above signs, it’s crucial to act before winter arrives. At Action Tree Service, we specialize in assessing tree risks and removing dangerous trees using mobile cranes. This equipment allows us to safely remove large or hard-to-reach trees without causing damage to nearby structures.

Here’s when you should consider calling a professional:

• If a tree has large dead limbs or branches that hang over your home, driveway, or power lines.
• If you see significant cracks in the trunk or signs of root instability.
• If a tree is leaning dangerously or has experienced recent root damage.

Our team of certified arborists and crane operators can handle any tree removal, even in complex or hazardous situations. By identifying and addressing dangerous trees before winter hits, you can prevent accidents and ensure that your property stays safe throughout the season.

Conclusion

Winter in Kelowna brings its fair share of challenges, but with proper tree care and vigilance, you can avoid many of the hazards associated with winter storms. Regularly inspecting your trees for dead branches, cracks, and other signs of instability is key to keeping your property and loved ones safe. If you have concerns about potentially dangerous trees, contact Action Tree Service for a professional assessment and removal.

Why Watering Trees in the Fall is Critical

Fall watering may seem unnecessary since trees are losing their leaves and heading into dormancy, but it plays a vital role in their survival. Trees, especially young or newly planted ones, still require water to sustain their roots during the cold months. In fact, roots continue to grow in the fall as long as the soil is not frozen, making this season one of the best times to support root development.

Fall watering prepares trees for winter by:

1. Preventing Drought Stress: As trees lose their leaves, they still need water to keep their roots hydrated. Dry soil can lead to drought stress, which weakens trees and leaves them vulnerable to winter damage.
2. Strengthening Roots: Fall is a prime time for root growth because the soil stays warmer than the air. Well-watered trees can continue developing strong roots that will help them thrive once spring arrives.
3. Helping with Insulation: Watering trees in the fall helps maintain the soil’s moisture content, providing insulation that helps moderate soil temperatures during winter. This reduces the risk of root freeze.

Proper Tree Watering Techniques for Fall

Watering trees in fall requires a slightly different approach compared to the warmer months. The key is to provide deep, thorough watering before the ground freezes, but not overwater, which could lead to root rot or other problems.

Best Practices for Fall Tree Watering

1. Water at the Right Time

The timing of fall watering is crucial. You want to continue watering until the ground begins to freeze, usually around late October to early November in colder climates. Stop watering once the ground is frozen, as the water won’t be able to penetrate and will simply sit on the surface.

In the fall, the tree’s need for water is reduced, so water less frequently than in summer. Aim to water about once every 10 to 14 days, depending on rainfall.

2. Water Deeply

Shallow watering doesn’t reach the tree’s deeper roots, which are the most important for sustaining the tree over winter. Instead, water deeply and slowly to ensure the soil is moist down to about 12-18 inches. This will provide enough water to the root zone without oversaturating the soil.

Use a slow trickle of water, such as from a soaker hose or drip irrigation system, to allow the water to penetrate deeply without running off. Watering too quickly can cause runoff and may not soak into the soil properly.

3. Avoid Watering the Trunk

Direct watering onto the tree’s trunk can cause rot and other problems. Instead, focus on the area under the tree’s canopy where the roots extend. For larger, more established trees, water in a circular pattern just inside and beyond the drip line (the outermost edge of the branches).

4. Check Soil Moisture Regularly

It’s essential to monitor soil moisture throughout the fall. Use a soil moisture meter or simply check the soil with your hand. If the top 2-3 inches of soil are dry, it’s time to water again. Avoid watering if the soil is already moist.

Fall Fertilization:
Boosting Nutrients for a Healthier Spring

While watering is critical, fertilizing your trees in the fall can provide them with the nutrients needed for healthy root development and stronger growth in the spring. Fertilization should be done carefully in the fall to avoid stimulating new leaf or branch growth, which can be vulnerable to winter damage.

Careful Fall Fertilization

1. Choose the Right Fertilizer

For fall fertilization, opt for a slow-release, low-nitrogen fertilizer. Nitrogen encourages leafy growth, which you don’t want in fall. Instead, look for a balanced fertilizer with a focus on phosphorus and potassium, which promote root growth and overall plant health.

A fertilizer with a formula like 0-20-20 (no nitrogen, high phosphorus and potassium) can help nourish the roots without spurring new top growth that could be damaged by frost.

2. Apply Fertilizer in Late Fall

The best time to fertilize trees is in late fall, after the leaves have dropped and the tree is fully dormant but before the ground freezes. This ensures the nutrients are available to the roots without encouraging unwanted new growth.

Spread the fertilizer evenly under the tree’s canopy, starting a few feet from the trunk and extending to the drip line. Water the area after applying fertilizer to help it absorb into the soil.

3. Mulch for Added Protection

After fertilizing, apply a layer of mulch around the base of the tree to insulate the soil, retain moisture, and protect the roots from freezing temperatures. Use organic mulch, such as wood chips or shredded bark, and spread it in a layer about 2-4 inches thick, keeping it a few inches away from the trunk to avoid rot.

Additional Tips for Fall Tree Care

• Prune with Care: Fall is not the ideal time for heavy pruning, as it can stimulate new growth. Instead, remove only dead or damaged branches.
• Check for Pests and Diseases: Inspect your trees for signs of pests or diseases and treat them before winter sets in.
• Avoid Overwatering: Too much water can suffocate roots and lead to rot, especially as temperatures drop.

An arborist is a person who specialises in the cultivation, maintenance, and study of trees, shrubs, and other permanent woody plants. They are also known as tree surgeons or tree care specialists. Arborists are educated specialists with knowledge of the biology, upkeep, diagnosis, and treatment of issues relating to trees.

What Credentials Do Arborists Require?

To work as an arborist in Kelowna, British Columbia, there are specific training and certification requirements that arborists need to have. In British Columbia, the Tree Service Industry Standard (TSI) is recognized as a guideline for safe work practices in the tree care industry. To meet these standards, arborists will pursue training and certification and qualifications through the International Society of Arboriculture (ISA). The ISA offers certification programs that credential activities based on an arborist’s knowledge and expertise in the field. ISA Certification is available to those who meet predetermined and standardized criteria for knowledge, skills, or competencies.

What Tree Services Can Certified Arborists Provide?

Tree Health Assessments

The health and condition of trees are evaluated by arborists, who look for problems including diseases, pests, structural flaws, or environmental stress. To improve tree health, encourage healthy growth, and guarantee safety, they execute pruning, trimming, and shaping techniques.

Tree Removal

Arborists may need to carefully remove a tree if it is dead, sick, or poses a risk to people or property. They use specialised tools and methods to cut down, disassemble, and remove trees without harming nearby buildings or the natural landscape. The arborists at Action Tree Service in Kelowna have the special privilege to hoist an arborist into a tree using a mobile crane. It is only through special work practices approved by Work Safe BC that this unique practice is permitted.

Tree Planting

Arborists can make planting recommendations based on their understanding of the right tree species for a given environment. They also take care of tree transplantation, making sure the right procedures are used to reduce stress and increase the likelihood of successful establishment of the new or transplanted tree.

Tree diseases and insect infestations

Tree diseases and insect infestations that threaten trees are diagnosed and treated by arborists. To avoid or control pests and tree illnesses that could be harmful to the health of trees, arborists will apply the proper treatments, such as spraying pesticides, fertilisers, or other interventions.

Safe Work Practices of Certified Arborists

Before every job, arborists assess the potential risks associated with the trees they are to work with, particularly those located near structures or high-traffic areas. Arborists will evaluate the hazards and likelihood of tree failure. Once identified the risk of hazardous conditions will be mitigated by planning and executing a work safe procedure where all hazards are individually addressed.

The Allure of the Okanagan Flowering Cherry

Aesthetic Appeal

The Okanagan Flowering Cherry, with its breathtaking blossoms, offers an unmatched spectacle of beauty each spring. The delicate flowers range in color from white to various shades of pink, creating a mesmerizing display against the backdrop of Kelowna’s scenic beauty. This tree not only adds a splash of color but also brings a sense of renewal and vitality to any garden.

Benefits Beyond Beauty

Aside from its aesthetic value, the Okanagan Flowering Cherry tree provides several ecological benefits. It serves as an early source of nectar for pollinators, supporting local bee populations and contributing to the health of your garden’s ecosystem. Additionally, its dense foliage offers shade during the warmer months, creating a cooler microclimate that can enhance the comfort and energy efficiency of your home.

Care and Maintenance

To ensure your Okanagan Flowering Cherry tree thrives, consider the following care and maintenance tips.

Planting and Location

Choose a site that receives full sun to partial shade, as ample sunlight is crucial for optimal flower production. The tree prefers well-drained soil, so if your garden has heavy clay, consider amending it with organic matter or choosing a raised bed or mound to improve drainage.

Watering and Nutrition

Regular watering is essential, especially during the first few years after planting and during dry spells. However, avoid overwatering, as the tree does not tolerate “wet feet.” A balanced, slow-release fertilizer applied in early spring can support healthy growth and flowering

Pruning and Care

Prune in late winter or early spring before new growth begins. Focus on removing any dead or diseased wood and thinning out crowded branches to enhance air circulation. This not only maintains the tree’s shape but also prevents disease.

Climate Resilience: A Match for Kelowna

The Okanagan Flowering Cherry tree is notably resilient to the climate of Kelowna, which ranges from USDA hardiness zones 5b to 7a. It can withstand the cold winters while thriving in the warm, sunny summers typical of the region. However, it’s important to provide some protection from the harshest winter winds, possibly by choosing a planting site near a building or a natural windbreak.

Wildfire Resilience: A Consideration for Kelowna Gardeners

Given Kelowna’s location in a region susceptible to wildfires, it’s vital to consider the wildfire resilience of any plant or tree added to your landscape. The Okanagan Flowering Cherry tree, like many deciduous trees, is considered less flammable than coniferous trees due to its higher moisture content and the nature of its leaves. However, no tree is completely fireproof. Implementing FireSmart landscaping principles, such as maintaining a defensible space around your property and choosing less flammable plants for areas closest to your home, can help reduce wildfire risk.
