Essential Tips for Tree Care During Heatwaves
As the summer begins to wind down, we can expect to see some of the highest temperatures of the year. Extreme heat can be incredibly damaging for people and nature alike, including our trees. This is why summer tree care needs to be intensified to help our trees and surrounding landscapes survive during heat waves.
Heatwave tree care is crucial for maintaining the health and vitality of your trees during the scorching summer months. Trees can suffer immensely in extreme heat, resulting in health issues and potential fatality if the right care is not given.
At Kneebone Trees, trees are our passion. Our dedicated team of arborists are dedicated to helping you protect and nurture your trees at all times of the year and deliver tree care services to ensure they thrive no matter the weather.
Using our expertise and passion for tree care, we are sharing some of the most important heatwave tree care tips to help your landscapes not only survive but thrive during some of the highest temperatures of the year.
Understanding Heat Stress in Trees
Heat stress is a menacing factor in the life of trees and becomes a major threat for landowners during heat waves and periods of extremely high temperatures. This phenomenon arises when a tree’s water loss outpaces the water uptake, causing the tree to lack to essential hydration and nutrition it needs to thrive.
This loss of water occurs through the process of transpiration and in times of extreme heat, such as heatwaves, can overtake the amount of water the tree absorbs from the ground. Much like how humans and animals can become victim to dehydration during high temperatures, our trees are also in danger which is why heatwave tree care is vital.
Heat stress is a precarious situation for our trees and landscapes as a whole, and requires keen observation and swift action.
There are some prominent symptoms that landowners should look out for during heat waves to determine whether their trees are suffering from heat stress and therefore need additional care.
The imbalance of water intake versus outtake can cause various issues, including:
- Wilting or browning leaves
- Reduced growth
- Increased susceptibility to pests and diseases
- Premature leaf drop
Being able to recognise these signs early on allows for prompt action, which can make all the difference in maintaining the health and beauty of your trees – even during heatwaves.
This is why a key part of heatwave tree care involves closely monitoring your trees’ condition during periods of intense heat. If you do notice any of these signs, you also need to provide your trees with the necessary support to minimise the damaging effects of heat stress to prolong the appeal of your landscape.
Top Tips For Heatwave Tree Care
As heat stress is a major threat to our trees and surrounding landscapes during heat waves, you must improve your tree care processes to cover the additional needs during this time.
Not only should you monitor your trees for any signs of heat stress, but implementing these heatwave tree care tips can also help to prevent these issues in the first place and enhance the health of your landscapes even during extreme temperatures.
1) Watering Wisely
Proper watering is the foundation of effective heatwave tree care and is the main tool to support all forms of plant life during high temperatures.
Much like how our lawns or flowers require extra watering during the hottest season, so do our trees. As heat stress causes trees to lose more water than they can absorb, therefore putting them at risk of dehydration and irreversible symptoms, watering should be one of your main concerns when it comes to heatwave tree care.
There are various methods you can implement for hydration during heatwaves, such as:
Deep Watering
Instead of frequent shallow watering, opt for deep watering during times of extreme heat. This method encourages roots to grow deeper into the soil, increasing their access to moisture and allowing all areas of the tree to receive the hydration it needs, regardless of the evaporation which may happen closer to the surface.
Deep watering does have a particular process to ensure that your trees are getting the hydration they need during heatwaves. There are three methods that you can use to ensure deep watering of your trees and support them during periods of scorching heat:
- Water slowly and deeply at the base of the tree, applying as much water as possible.
- Use a soaker hose or drip irrigation system to deliver water gradually.
- Apply water to the root zone (the area under the tree’s canopy) rather than the trunk.
Water Timing
Timing is everything when it comes to heatwave tree care, as the time of day you choose to water your landscape can impact how much hydration the trees actually get.
This is why it is recommended that you water your trees early in the morning or late in the evening during the summer, and in particular during periods of extreme heat.
These cooler parts of the day reduce evaporation, allowing more water to reach the roots of the tree and passing hydration throughout the plant to support its growth.
Water Frequency
Much like with timing, how often you water your trees also plays a big role in effective heatwave tree care. The frequency of watering will differ based on the type and age of trees in your landscape.
For example, young trees should be watered every 2-3 days during a heatwave, while established trees can be watered once a week as this allows them to get enough hydration from the roots. It is important to note that this frequency may need to be adjusted based on your soil type and the weather conditions of your particular area.
2) Mulching
Mulch is a tree’s best friend during a heatwave and therefore needs to be a key part of your heatwave tree care process.
Mulch is a great tool for all kinds of plant life and should be used across your landscape because of the benefits it provides. It helps retain soil moisture, regulates soil temperature, and reduces weed competition so your trees can continue to thrive even when they are faced with high temperatures.
Here’s how to mulch effectively during a heatwave, or at any other time of the year:
- Apply a 2-4 inch layer of organic mulch (e.g., wood chips, bark, or compost) around the base of the tree.
- Extend the mulch out to the drip line (the edge of the tree’s canopy).
- Keep mulch away from the trunk to prevent rot and pests, limiting the impact of diseases on the tree’s growth.
3) Pruning with Caution
Pruning is an essential part of tree care at all times of the year but becomes particularly significant during heatwaves.
During heatwaves, tree pruning should be approached with caution as pruning at the wrong time or pruning too much can hinder the health of your tree, making it more susceptible to heat stress.
When to Prune
As part of your heatwave tree care, it is vital to know when you should prune your landscape. It is a good idea to completely avoid heavy – or any – pruning during extreme heat as this can leave your trees exposed to higher risks of heat stress, disease and other issues.
If pruning is necessary during this time, then you need to alter your routine. When pruning during a heatwave, focus on removing dead, damaged, or diseased branches only and do not attempt to do anything else to the tree as the temperatures continue to rise.
Instead, you should wait until cooler weather for more extensive pruning and shaping – or call professional tree surgeons to handle this task when the weather changes.
How to Prune
Understanding how to prune is just as important as knowing when, as this all contributes to the health and growth of your trees.
When pruning trees during heatwaves or any other time of the year, you need to ensure you are using sharp, clean tools to make precise cuts. This reduces stress on the tree and helps it heal faster.
You must always follow proper pruning techniques to avoid damaging the tree or rely on professional tree surgeons to do this work for you.
4) Protecting the Soil
Healthy soil is vital for healthy trees, much like with any other plant life you may have in your landscape. Soil is the foundation of healthy growth and needs attention all throughout the year, but additional care is required during a heatwave when more support is needed.
During a heatwave, it’s essential to protect the soil around your trees to support ongoing hydration and growth. Implement the following into your heatwave tree care routine to support the needs of your landscape and prevent heat stress from taking over your trees:
Soil Aeration
Compacted soil can restrict root growth and water absorption, which is why regular aeration is a good idea all year round. Aerate the soil around your trees regularly to improve air and water flow.
This can be done using a garden fork or aeration tool and should be done at least once during heatwaves to improve hydration to the tree, limiting the impact of heat stress.
Soil Amendments
Some amendments may be required to make your soil more effective and supportive of your trees during this time. A good option is to add organic matter to the soil, as this can improve the water-holding capacity to give your trees more hydration when they need it the most.
You may also want to consider incorporating compost or well-rotted manure into the soil around your trees, as this can help to enhance the structure and fertility.
5) Shading and Wind Protection
Providing additional shade and wind protection can significantly reduce stress on your trees during a heatwave and should be implemented whenever possible.
There are two major options for this kind of heatwave tree care, including:
Temporary Shading
To reduce the heat on your trees and limit their sunlight exposure, you can erect temporary shade structures around them. This can be done using shade cloth or old bedsheets, as long as they are big enough to cover a large surface area of the tree to reduce the impact of direct heat.
When installing temporary sharing, you also need to ensure the covers continue to allow some light through, as this is essential for the growth of your trees and protecting the tree from direct sun exposure during these high temperatures.
Windbreaks
Strong winds can exacerbate water loss through evaporation, putting your trees more at risk and resulting in permanent damage to their structure.
Windbreaks should be a key part of your heatwave tree care and they can be easily installed. You can either plant windbreaks into the soil around your tree or use temporary barriers as both can help shield your trees from hot, dry winds during this time.
6) Monitoring and Maintenance
Regular monitoring and maintenance are key to successful tree care at any time of the year, but your efforts should be increased during heatwaves to protect your landscape and make sure your trees are safe even in high temperatures.
There are several main checks that you should be performing regularly and increase for heatwave tree care, such as:
Check Soil Moisture
You can check the moisture levels within the soil around your trees using a soil moisture meter or simply by digging a small hole near the tree to manually check moisture levels.
When checking the moisture levels of the soil, you are making sure that the tree is hydrated and not suffering from heat stress. During these checks, you need to make sure that the soil is consistently moist but not waterlogged.
Inspect Trees Regularly
As part of your heatwave tree care, as well as any other seasonal care, you need to regularly inspect your trees for signs of stress, disease and pests.
These inspections should be done more regularly during heatwaves, as trees become more susceptible to stress during this time. When inspecting your trees, look out for common signs of heat stress such as wilting leaves, leaf scorch, or pest infestations.
Finding these early enough can allow for a complete recovery with your tree, as early detection allows for prompt action.
7) Adjust Care as Needed
Tree care is an ongoing task and one that you should be putting effort into regardless of the weather. However, during heatwaves or other extreme weather conditions, you may need to add more steps to your tree care routines.
This is why one of the most useful tips for heatwave tree care is to remain flexible and be prepared to offer your landscape the care they need when they need it. As a landowner, it is a good idea to remain flexible with your care routine as you can easily tailor your routines to meet the demands of nature at any given time.
Trees may need extra attention and adjustments based on changing weather conditions, such as during heatwaves. Be flexible and allow for your landscape to inform the kind of care it needs at any given time.
Conclusion
Caring for your trees during a heatwave requires a combination of proper watering, mulching, cautious pruning, soil protection, shading, and regular monitoring.
