How to Ensure Your Trees and Shrubs Thrive in Cooler Weather

Trees and Shrubs

With the onset of cooler weather, it’s crucial to ensure the health and longevity of your trees and shrubs. In these conditions, trees and shrubs face a new set of challenges that can potentially impact their health and longevity, such as pest infestations, diseases, and the occasional dip in temperatures.

Here, we’ll discuss some of the best ways to keep your trees and shrubs in tip-top shape.

1. Winter Pruning: The Perfect Time for Tree and Shrub Maintenance

The dormant season, particularly late winter, is an optimal time to prune deciduous trees and shrubs. During this period, plants are less susceptible to diseases and insect infestations, thereby providing the most suitable conditions for pruning. Proper pruning techniques and targeted maintenance go a long way in shaping your trees and shrubs for robust growth and reduced risk of damage. Key points to remember while pruning include:

  • Remove any dead, damaged, or diseased branches and limbs, as these can compromise your plants’ health and invite pests.
  • Encourage growth in desirable patterns by pruning out crossing branches and ensuring ample space between limbs.
  • Promote better air circulation and light penetration by thinning out excessively dense growth.
  • Regularly sharpen your pruning tools and sanitize them between uses to avoid spreading diseases.

2. Mulching: A Layer of Protection for Your Trees and Shrubs

A layer of mulch around your trees and shrubs provides many benefits, particularly during cooler weather. Mulch helps insulate the soil, protect roots from extreme temperatures, and retain moisture, which is essential for overall plant health. To maximize the advantages of mulching, consider the following guidelines:

  • Choose the right type of mulch. Organic mulch options like wood chips, bark, or compost are ideal as they eventually decompose, adding valuable nutrients to the soil.
  • Apply mulch in a 2-4 inch deep layer around the base of your trees and shrubs, keeping at least a couple of inches away from the trunk to avoid rot and respiration problems.
  • Aerate your mulch periodically to prevent the formation of an impenetrable layer, ensuring optimal air and water circulation.

3. Protecting Trees and Shrubs from Winter Desiccation

Winter desiccation, or the drying out of plant tissue due to extreme cold and wind, can cause significant harm to your trees and shrubs. To mitigate the risks associated with winter desiccation, include these protective measures as part of your cooler weather care routine:

  • Carefully select plant species that are naturally better suited for the local climate and the specific conditions of your geographical region.
  • Create windbreaks using fencing, taller and hardier shrubs, or burlap barriers to protect sensitive trees and shrubs from harsh winds and extreme cold.
  • Ensure your trees and shrubs receive adequate water throughout the fall season. Well-hydrated plants are better equipped to withstand harsh winter conditions.
  • Employ the use of anti-desiccant sprays that form a protective coating on foliage, reducing moisture loss during the colder months.

4. Monitoring and Managing Common Winter Pests

Despite the cooler temperatures, certain pests may remain active and can cause harm to your trees and shrubs during the winter months. Monitoring and managing these pests are crucial to maintaining the health of your landscape. The most common winter pests include:

  • Bark Beetles: These pests bore into the bark of trees, especially those in stress due to drought or other factors. Infested trees may experience yellowing foliage, dieback, and even death. In early-to-mid winter when temperatures are above freezing, applying insecticides containing pyrethroids can help manage bark beetles.
  • Winter Moths: The larvae of winter moths feed on tree and shrub leaves, eventually causing defoliation. Infestations can be managed by applying horticultural oil on the trunks, branches, and twigs of susceptible deciduous trees and shrubs during the dormant season.
  • Scale Insects: Scale insects suck sap from trees and shrubs, causing yellowing of leaves, stunted growth, and even plant death. To control scale insects, apply horticultural oil during the dormant season, targeting nymphs and eggs on twigs and branches.

5. Detecting and Treating Cold Damage in Trees and Shrubs

Exposure to freezing temperatures can create frost cracks, cause tissue damage, and disrupt the flow of nutrients and water within your trees and shrubs. Knowing how to detect and treat cold damage can help you effectively address the effects of chilly weather on your landscape. Here’s what you need to know about handling cold damage:

  • Frost cracks often appear as vertical splits in the bark and can be an entry point for diseases and pests. Applying a trunk wrap on susceptible trees prior to freezing conditions can help prevent frost cracks, but be sure to remove it during the growing season to avoid moisture accumulation.
  • If it occurs, ice and snow buildup on branches can lead to breakage and potential damage. Resist the urge to shake the ice off, as this can harm the already brittle branches. Instead, let the ice or snow thaw naturally or use a broom to gently remove the weight, brushing in an upward motion.

In case of branch breakage due to ice or snow accumulation, pruning the damaged limbs properly is essential. Make clean cuts close to the collar of the branch, which facilitates quicker healing and reduces the risk of diseases.

Remember, partnering with a professional green space company like Fairway Lawns can help you tackle the challenges of winter tree and shrub care with their expert guidance, services, and tools. Their customized tree and shrub care programs can help ensure your landscape remains healthy and vibrant throughout the cooler months and beyond.

6. Maximizing the Benefits of Dormant Season Fertilization

Fertilizing your trees and shrubs in the dormant season can be beneficial as it promotes root growth and helps them absorb essential nutrients, making them better prepared for the growing season. Although not all trees and shrubs require winter fertilization, certain species—particularly those that are nutrient-deficient—may benefit from it. Consider these guidelines for fertilizing during cooler months:

  • Use a slow-release, well-balanced fertilizer with an appropriate ratio of nitrogen, phosphorus, and potassium for your specific plantings.
  • Follow the recommended application rates specified on the fertilizer packaging.
  • Apply fertilizer evenly around the base of your trees and shrubs during late fall or early winter to allow slow absorption through the cooler months.

7. Protecting your Trees and Shrubs from Rock Salt Damage

Rock salt is commonly used in colder regions to melt ice and snow on sidewalks, driveways, and roads. However, excessive exposure to rock salt can cause harm to your trees and shrubs, leading to a range of issues from defoliation to root damage. To minimize the impact of rock salt on your landscape, follow these precautionary measures:

  • Opt for alternative ice melt products, such as calcium magnesium acetate (CMA) or calcium chloride, which are less damaging to plants.
  • Create barriers using burlap or plastic fencing to protect sensitive trees and shrubs from rock salt exposure.
  • If using rock salt, apply it sparingly and mix it with abrasive materials such as sand or sawdust to reduce its impact on your landscape.
  • Thoroughly water your trees and shrubs in early spring to help dissolve and flush out any accumulated salt in the soil.

8. Providing Winter Care for Newly Planted Trees and Shrubs

Young trees and shrubs need special attention during winter to ensure their survival and growth. As their root systems are less established and more susceptible to damage from the elements, it’s crucial to provide proper care to safeguard their future health and wellbeing. Consider the following guidelines for nurturing your newly planted trees and shrubs through the cold months:

  • Wrap the trunks of young trees with a protective wrap, such as tree guards or spiral tree wraps, to shield them from temperature fluctuations, sunscald, and frost cracks. Be sure to remove the wrap during the growing season.
  • Construct a cylinder-shaped, wire mesh barrier around young trees or shrubs to deter browsing deer and rabbits, which often damage bark and branches in search of food during the winter months.
  • Apply a 2-4 inch layer of mulch around the base of your newly planted trees and shrubs to help retain moisture levels, stabilize soil temperatures, and suppress weed growth.
  • Ensure adequate watering during the fall season, allowing the soil to remain moist but not saturated around the roots.

9. The Role of Winter Dormancy in Trees and Shrubs

Understanding the biological processes that occur during winter dormancy can help guide your tree and shrub care practices throughout the cooler months. Dormancy is a natural adaptive response to cold temperatures and reduced sunlight, enabling trees and shrubs to conserve resources, withstand the harsh elements, and prepare for their next growth season. Key aspects of winter dormancy include:

  • Energy conservation: Slower metabolic rates during dormancy allow plants to conserve energy for essential processes like maintaining cell structure, repairing tissues, and surviving the winter.
  • Bud formation: Trees and shrubs form buds during the growing season that remain dormant through the winter, eliminating the risk of frost damage. These buds eventually break dormancy and initiate growth when temperatures and light conditions are favorable again.
  • Frost tolerance: During dormancy, trees and shrubs undergo physiological changes, increasing their tolerance to freezing conditions. By altering the composition of the fluids within their cells, they minimize the potential for frost damage.

10. Winter Interest: Choosing Trees and Shrubs that Shine in Cooler Weather

While many trees and shrubs lose their lustrous foliage and colorful blooms as temperatures drop, you can still achieve visual interest in your landscape. Consider incorporating trees and shrubs that offer appealing characteristics during the cooler months, such as:

  • Winterberry (Ilex verticillata): These deciduous holly plants produce clusters of bright red berries that persist throughout winter, providing a vibrant pop of color in a stark landscape.
  • Redtwig Dogwood (Cornus sericea): This deciduous shrub is known for its striking red stems that create a stunning visual contrast against snowy backdrops.
  • Eastern Redbud (Cercis canadensis): This small tree displays eye-catching branching patterns and interesting bark textures, adding visual interest to the winter landscape.
  • Witch Hazel (Hamamelis spp.): Certain witch hazel species bloom in late winter or early spring, showing off unique, fragrant flowers that can brighten up a dormant landscape.

11. Implementing Proper Irrigation Techniques for Winter Tree and Shrub Care

Although water requirements tend to reduce during cooler weather, the proper hydration of trees and shrubs remains essential for their survival through the colder months. A well-hydrated root system helps in resisting the damaging effects of freezing temperatures and desiccation. To ensure adequate irrigation during the winter, consider the following strategies:

  • Monitor soil moisture levels by conducting regular checks. If the soil feels dry an inch below the surface, it may be time to water.
  • Focus on deep and infrequent watering to promote stronger root growth, rather than short and frequent waterings, which can result in shallow roots.
  • Water early in the day and while temperatures are above freezing to give the liquid enough time to absorb before nightfall and minimize the risk of frost damage.
  • Avoid over-watering, as this can cause root rot and other diseases, preventing plants from effectively taking up essential nutrients.

12. Anticipating and Addressing the Effects of Climate Change on Trees and Shrubs

With climate change comes the increasing likelihood of fluctuating weather patterns, extreme temperatures, and prolonged droughts that can impact the health and vitality of your trees and shrubs. By incorporating climate-resilient strategies into your tree and shrub care practices, you can better prepare and protect your landscape for the challenges ahead. Here are some tips on how to address climate change:

  • Plant a diverse range of trees and shrubs to improve overall resilience against disease, pests, and extreme weather conditions.
  • Choose native species that are well-adapted to your local environment and more resistant to shifting temperatures and weather patterns.
  • Pay close attention to and follow shifting USDA hardiness zones, which serve as guidelines for selecting suitable plant species based on average annual extreme minimum temperatures. As some zones have been reclassified due to climate change, it’s crucial to adhere to the latest zoning information. 

Implement water-conserving techniques, such as utilizing drip irrigation systems, to optimize water usage and address potential drought conditions.

13. Understanding How Different Tree and Shrub Species React to Cooler Weather

A critical aspect of ensuring your trees and shrubs thrive in colder months is understanding the needs and tolerances of the different species within your landscape. By knowing which plants require specific attention and care during cooler weather, you can better protect your investment and maintain a healthy, vibrant landscape throughout the year. Some popular tree and shrub species, along with their winter care requirements, include:

  • Evergreens: Unlike deciduous trees and shrubs, evergreens retain their foliage all year, which can result in increased moisture loss during winter. Focusing on adequate hydration, the application of anti-desiccants, and protective windbreaks are vital to maintaining the health and vitality of evergreens during cooler months.
  • Fruit trees: Many fruit tree species, including apple and cherry trees, require special attention during the winter. Pruning during the dormant season is critical for overall fruit production and tree health. Ensuring proper pest and disease management is also essential to safeguard against potential infestations and infections that can lead to reduced fruit yield and quality.
  • Hydrangeas: These popular flowering shrubs require specialized care, which is based on their variety. While some species can tolerate harsh winters with little protection, others are more vulnerable to cold temperatures. Protect sensitive species by surrounding the base with a cage filled with fallen leaves or straw and wrapping burlap around the cage to deter wind chill.
