Oh, summer! The season of outdoor barbeques, pool parties, and longer daylight. While we’re outdoors enjoying the warmth, the trees may be struggling. High heat and dryness may destroy these peaceful sentinels of our yards. What can you do to keep your trees alive in the scorching heat? Here are some tips for keeping your trees healthy and vibrant all summer.
Watering is Key
In the height of summer, when the sun blazes and the ground thirsts for moisture, trees, much like every other living thing, feel the impact of the intense heat. Proper watering becomes not just beneficial but essential for their health and survival.
Deep watering is a technique that proves most effective during these times. Unlike a quick sprinkle, which might only dampen the surface, deep watering is a deliberate act of letting water flow slowly so it reaches well into the soil. The rationale behind this approach is that it promotes the roots to grow downwards, seeking the coolness and moisture of the deeper layers. Trees with deeper root systems have an advantage; they become more resilient and drought-resistant. They tap into underground water reservoirs, giving them a lifeline during the driest periods.
The time of day you water matters significantly, too. The early morning or late evening are the best times to water your trees. Doing so at the peak of the day might seem like a refreshing treat, but in reality, much of that precious water simply evaporates before it can be absorbed. By watering during cooler parts of the day, you ensure that the maximum amount of water penetrates the soil and reaches the roots without being lost to the heat of midday.
Mulch to the Rescue
Gardeners often use mulching as a “secret weapon” in summer. It is more than just a pretty addition to tree bases-it solves several summer tree problems.
Mulch retains moisture, one of its main benefits. A mulch barrier protects plants from extreme heat and water shortages. Lowering evaporation retains soil moisture longer. Water retention is essential for plants because it helps their roots absorb the needed water.
Mulch also stabilises soil temperature. Like individuals who struggle to acclimatise to summer’s scorching afternoons and cold evenings, tree roots prefer a more steady environment. The soil is insulated from the sun’s direct heat by mulch, preventing it from heating up unsafely. This temperature consistency supports better roots and tree health.
Weeds, those unwelcome guests in any garden, find it harder to establish themselves in mulched areas. By covering the soil, mulch inhibits the growth of these pesky plants, which might otherwise compete with trees for essential nutrients and water.
However, while mulching offers a host of benefits, it’s essential to apply it correctly. A layer that’s 5-10 cm deep is generally recommended. It’s also crucial to avoid piling mulch directly against the tree trunk, which can create a moist environment ripe for fungal infections or pest invasions. Instead, it’s wise to leave a small gap around the base of the tree.
Prune with Purpose
Pruning, the art and science of selective tree trimming, is pivotal in ensuring tree health. While summer may not be the prime season for a full pruning session, it becomes an opportunity to address specific issues, ensuring that trees are not expending energy on parts no longer beneficial to their overall health.
Why prune in summer? Isn’t spring or fall the usual time for such tasks? While major pruning activities might be reserved for other times of the year, summer presents a clear view of a tree’s canopy, making it easier to identify and remove dead or damaged branches. These problematic branches become more evident without the camouflage of other foliage or the disguise that other seasons might offer. Removing them ensures that the tree’s energy and resources are channelled towards healthy growth.
Additionally, certain diseases are less active during the warmer months, reducing the risk of infection at the pruning sites. Moreover, summer pruning can be strategic. For instance, if a tree grows too vigorously in an unwanted direction, a summer prune can redirect its energy, curbing unwanted growth.
Pruning is helpful, but it must be done carefully to achieve the intended outcomes. Over-pruning, or cutting too deeply or in the wrong places, can damage a plant and invite pests and diseases. If a tree is already stressed due to dryness, making large cuts would only increase its stress.
Consult with an arborist or tree specialist when in doubt is always a good idea. Their expertise can guide you on the best practices for summer pruning, ensuring that every cut is purposeful and benefits the tree’s health and structure.
Protect the Bark
The bark of a tree is much more than just its outer covering. Protective skin shields the delicate inner tissues from pests, diseases, and physical injuries. Just as our skin acts as the first defence against external threats, a tree’s bark plays a similar, vital role in its health and well-being. As such, ensuring its integrity during the summer months, when outdoor activities increase, becomes paramount.
The increase in outdoor activities during summer-whether it’s children playing, mowing the lawn, or engaging in landscaping projects-means trees face a heightened risk of unintentional damage. A stray football, an errant lawnmower blade, or a misplaced garden tool can all cause nicks, scrapes, or more significant wounds to the bark. Even seemingly minor damages can have lasting consequences. A break in the bark is akin to an open wound, making the tree vulnerable to infections, fungal diseases, and opportunistic pests that might take advantage of this breach.
Moreover, damaged bark can hinder a tree’s ability to effectively transport essential nutrients and water. A tree’s vascular system, which lies just beneath the bark, is its lifeline. Any interruption or damage to this system can stunt growth, cause branches to die, or, in extreme cases, lead to the decline of the entire tree.
To protect the bark during summer, heightened awareness is the key. When engaging in yard work or other outdoor activities, being mindful of the proximity to trees is essential. Using barriers or protective guards around younger or more vulnerable trees can also be a proactive measure against potential collisions or accidents. If mowing near a tree, it’s wise to use caution, ensuring that the mower or trimmer doesn’t come in direct contact with the tree’s base.
Lastly, if you notice a wound or damage to the bark, it’s crucial not to peel or tear away the loose bark. Instead, let the tree heal naturally, or if the injury seems severe, consult with a tree care professional for guidance on treatment or protection.
Look Out for Pests and Diseases
With its warm days and balmy nights, summer not only beckons us outdoors but also becomes a season of activity for various pests and diseases that can affect our trees. Just as we enjoy the summer’s vibrancy, these organisms find the conditions ideal for proliferation, making it a crucial time for tree owners to be vigilant and proactive.
Our gardens’ magnificent trees are more than just beautiful monuments. Many animals interact in these complex ecosystems. Some of these interactions threaten our tree population, but most are harmless or beneficial.
Aphids, beetles, and caterpillars may be more active in summer. These pests may devour plant leaves, bark, or roots for nourishment. While a few insects may not be a major threat, a full-blown infestation might cause leaf loss, growth retardation, or tree mortality.
Similarly, summer’s warm and often humid conditions can become a breeding ground for various fungal diseases. Signs such as discoloured leaves, unusual growths, or a sudden decline in a tree’s vitality can indicate the presence of a disease.
So, how can one ensure the well-being of trees amidst these potential threats?
First and foremost, regular inspection becomes the cornerstone of preventive care. By frequently examining your trees-looking at their leaves, branches, trunk, and the surrounding soil-you can often catch early signs of pests or diseases. Early detection often makes management easier and more effective.
Moreover, understanding the specific threats in your region can arm you with knowledge. Different areas might have unique pests or diseases that are more prevalent. By being aware of these, you can be on the lookout for specific signs or symptoms.
If you suspect your tree is under attack, it’s essential not to panic. Not every bug is a pest, and not every discolouration is a sign of disease. Sometimes, nature has its way of balancing things out. However, if you’re concerned or the issue seems to be escalating, seeking advice or services from a tree care professional or an arborist can be invaluable. They can provide insights, treatment options, and preventive measures tailored to your tree’s needs.
Avoid Fertilising in High Heat
When we consider the care of our trees during the summer, instinct might drive us to provide extra nourishment, assuming that more nutrients will fortify them against the season’s harsh conditions. However, restraint and understanding are crucial when it comes to fertilising during periods of high heat. Introducing fertiliser at the wrong time, particularly in the midst of summer’s peak temperatures, can do more harm than good.
The rationale behind avoiding fertilisation during extreme heat is how trees naturally respond to stress. During high temperatures, trees often enter a survival mode, conserving resources by slowing down growth and focusing energy on their most crucial functions. This natural redirection of energy is a delicate balance, an intrinsic rhythm that the trees adapt to weather the stress of scorching conditions.
Introducing fertilisers high in nitrogen or other chemicals during this period sends a confusing signal to the trees. They interpret these nutrients as a directive to grow, pushing them out of their survival mode. This results in tender, new growth that is particularly vulnerable to sunscald and may dramatically increase water requirements, a demand that can be challenging to meet when the sun is relentlessly drawing moisture from the soil.
Additionally, the salt content found in many fertilisers can contribute to the dehydration of the soil, further depleting the tree’s already scarce water supply. This situation can lead to a scenario where, despite your best intentions, the tree becomes even more stressed and susceptible to damage or disease.
Instead of fertilising the tree during extreme heat, focus on watering, mulching, and maintaining its health. If you believe your trees need more nutrients, wait until October to give them to them. Trees are more receptive to new growth, and environmental stressors are reduced.
It’s also advisable to conduct a soil test before any fertilisation. This test can reveal the nutrient makeup of your soil, highlighting what’s missing and preventing unnecessary applications. Consulting with a tree care professional or arborist can also guide you on the best practices for your trees and local climate conditions.
Provide Some Shade
While trees are often seen as the providers of shade, sometimes, in certain circumstances, they too can benefit from a little protection from the relentless summer sun. This is especially true for younger trees, newly planted specimens, or those with delicate or light-coloured bark, which might be more susceptible to sunscald or sunburn. By offering them shelter during the hottest parts of the day, we support their overall health and aid in their establishment and growth.
The logic behind shading trees, especially the younger ones, is akin to why we might seek out the shade of a canopy during a particularly sunny day. Young trees still need to develop a robust canopy or the thick bark that older trees possess. This lack of natural protection makes them particularly vulnerable to intense UV rays, which can cause damage to their tender leaves and bark. Sunburn in trees can manifest as discoloured or sunken bark, and in severe cases, this damaged bark might crack or peel, exposing the tree to infections and pests.
How can one provide shade to a tree, especially when it’s often the tree we look to for shade? There are several creative and effective strategies to consider:
- Temporary Shade Cloth: Garden centres often sell shade cloths that can be strategically placed to shield trees from the harshest midday sun. These cloths, made from woven material, allow for airflow while reducing the intensity of sunlight, creating a protective barrier.
- Umbrellas or Canopies: For smaller trees or those in pots, a large umbrella or a pop-up canopy can be positioned to cast a shadow during the sunniest parts of the day. This method offers the flexibility of being easily moved or adjusted as the sun shifts.
- Planting Companion Plants: Strategically placing taller plants or shrubs around a young tree can act as a living sun shield. As these plants grow, they cast natural shade, protecting the tree and enhancing the aesthetics of the space.
- Whitewashing: Some gardeners opt to whitewash young tree trunks in areas where the sun’s intensity is particularly strong. Water and white latex paint can be applied to the trunk, reflecting sunlight and preventing sunburn. This method is especially common in orchards or with fruit trees.
While it might seem counterintuitive for a tree, providing shade underscores the importance of understanding the unique needs of every tree in our care. Recognising that not all trees, especially the young or vulnerable, can withstand the unfiltered intensity of the summer sun is a testament to a gardener’s attentiveness and adaptability. With a little foresight and some shading strategies, we can ensure that our trees transition from their life’s vulnerable stages to becoming the mighty, shade-providing giants of tomorrow.
Stay Vigilant During Droughts
Despite the summer heat, droughts often accompany it. In times of below-average rainfall, when dry soil splits and water sources decrease, our trees need human assistance more than ever. Droughts may stress trees, making them more susceptible to sickness, infestation, and even mortality; thus, monitoring is crucial.
In extended dry weather, a tree shifts moisture from its leaves and branches to its root system to conserve water. This survival method can keep the tree alive, but if the drought lasts too long, its supplies will be exhausted, killing it.
During these dry spells, the challenge is not just to provide water but to do so effectively and efficiently, ensuring the precious little water available is used to maximum benefit. So, how can we, as caretakers, support our trees during these trying times?
Understanding a tree’s water needs is paramount. Not all trees require the same amount of water, and factors such as species, age, and location can significantly impact water requirements. Younger trees, having had less time to establish extensive root systems, are particularly vulnerable during droughts and require more frequent watering sessions.
Deep watering is a technique that encourages healthy root growth. Rather than frequent shallow watering, which only moistens the surface, deep watering involves infusing water slowly into the ground, reaching the deep root systems. This method encourages the roots to grow deeper into the soil, where moisture remains longer and helps trees become more resilient in future droughts.
Mulching, as discussed earlier, is also a saviour during droughts. By insulating the soil, mulch keeps it cooler and significantly reduces evaporation, retaining precious moisture. Additionally, it suppresses weeds that might compete with the tree for water resources.
It’s also wise to minimise additional stress on your trees during droughts. This means holding off on extensive pruning, fertilisation, or any activity that might stimulate growth and thus increase the tree’s water demand. It’s also a time to be extra vigilant against pests and diseases, as stressed trees are more susceptible to infestations.
Conclusion
In conclusion, while summer offers a lot of joy for us humans, it can be a challenging time for our trees. But with some extra care and attention, your trees can survive and thrive during the hottest months. Remember, trees are long-term investments, offering shade, beauty, and even increasing property value. So, let’s do our part to ensure they stand tall and healthy for many summers to come!
