Trees provide shade, beauty, and fruit to a healthy garden or yard. Like all living things, trees need care to be healthy. Whether you are a professional gardener or just someone who likes the peaceful beauty of a well-tended tree, the following basic tree care rules will ensure that your trees stay healthy and alive.
Watering is Key
All plants, including trees, need water to survive. Young trees need constant moisture to establish their root systems and flourish. Mature trees may get water from the ground because of their deep, widespread root systems. When a tree is freshly planted, its roots are transitioning, trying to spread out and anchor the tree while drawing nutrients from the soil. This process requires a consistent supply of water.
Watering young trees once a week is beneficial during the initial stages, providing them with approximately 37-75 litres of water, depending on the tree’s size and the local climate. This doesn’t mean you should drench the ground; it’s about maintaining a consistent moisture level. Deep irrigation helps a tree build a robust foundation by deepening its roots. If drought strikes again, the tree strengthens and makes it more drought-resistant.
The watering needs may be reduced considerably for mature trees, but this doesn’t mean they should be neglected, especially during dry periods. Extended periods without rain can stress even the most established tree. In these conditions, occasional deep watering can be a lifesaver, replenishing the deeper soil layers and ensuring the tree’s roots remain hydrated.
It’s also crucial to avoid overwatering. While trees, especially young ones, need consistent moisture, waterlogged soil can lead to root rot and other issues. It’s a delicate balance, and understanding your tree’s needs is crucial. When watering, checking the soil’s moisture level is a good practice. Waiting before the next watering session might be best if the ground is still moist several inches down.
Mulch for Moisture and Protection
Mulch is more than a garden or yard decoration-it protects trees and helps the soil around them retain moisture. When applied properly, mulch may greatly increase a tree’s health and vitality, especially throughout its growth.
One of the mulch’s biggest benefits is moisture retention. The availability of water may affect trees, especially newly planted ones. Mulch regulates soil moisture, ensuring tree roots receive enough water. This is especially beneficial in hotter months in drought-prone areas where soil can dry out quickly. Mulch slows evaporation, allowing the tree to absorb more water from the soil.
Mulch suppresses weeds and conserves water. Weeds are unattractive and compete with trees for soil resources. Mulch prevents weeds and other plants from competing with the tree for nutrition.
Additionally, mulch is a cushioning layer, protecting against potential physical damage. Lawnmowers, string trimmers, and other garden tools can inadvertently damage the base of a tree. This damage can make the tree more susceptible to diseases or pest infestations. A layer of mulch creates a clear boundary, signalling caution when approaching the tree and reducing the risk of unintentional harm.
However, while mulching has numerous benefits, proper application is crucial. Piling mulch too high against the tree’s trunk can lead to moisture accumulation, which can cause rot. It’s essential to ensure that while the mulch covers the ground around the tree adequately, it should not touch the tree trunk directly. Ideally, a doughnut-shaped application is recommended, where the tree trunk sits in the centre of a mulch ring.
Another important step is choosing the right mulch. Organic mulches like wood chips, bark, or leaves provide the advantages mentioned and degrade, contributing nutrients to the soil.
Mulching is a minor part of tree care. However, it greatly affects tree health. It is a simple but effective way to give trees the best habitat to grow, prosper, and benefit the community.
Prune with Purpose
Pruning is an art because it removes branches or stems from a tree to improve its health, shape, and growth. Despite the contradiction of pruning a living creature to make it healthy, arboriculture relies on it.
One of the main purposes of pruning is to remove sick, diseased, or damaged branches. This enhances the tree’s appearance and eliminates risks. Brittle or damaged branches are more prone to fall during a storm, endangering property and persons. Eliminating unhealthy tree parts prevents the sickness from spreading, improving tree health.
Pruning can also shape tree growth. By cutting branches at key intervals, you may shape tree development. This will help the tree grow balanced and attractive. This benefits urban and suburban areas where trees must be removed from power lines, buildings, and other structures. Urban and suburban areas benefit from this.
Another vital aspect of pruning is the promotion of better air circulation and sunlight penetration. When branches become too dense, it can limit the amount of light reaching the inner sections of the tree, which can hinder growth and make the tree more susceptible to diseases. A thick canopy can also trap moisture, creating a haven for fungal diseases. Thoughtful pruning can alleviate these issues, creating a healthier environment for the tree.
Despite its many benefits, it’s essential to approach pruning with caution and knowledge. Random or excessive cutting can harm a tree, leading to stunted growth or increased disease vulnerability. It’s often recommended to prune during a tree’s dormant season. This reduces tree stress and disease transmission when many pests and diseases are less active. There are exceptions, most notably in illness and threat management.
The tools used for pruning also matter. Sharp, clean tools make cleaner cuts, which heal faster and are less susceptible to infections. After each pruning session, cleaning and disinfecting tools is a good practice, especially if you’ve been removing diseased tree sections.
Fertilise If Needed
Like all living organisms, trees require a balanced diet to thrive. This “diet” comes from nutrients absorbed from the soil. Over time, however, even the most fertile soils can become depleted, especially in urban settings or areas where the same ground supports multiple plantings year after year. This is where fertilisation comes into play, offering trees the supplemental nutrients they might lack.
Fertilising is about adding nutrients and understanding what the tree needs. Adding fertiliser without understanding the requirements can do more harm than good, potentially leading to nutrient imbalances or even toxic build-ups. A soil test is often the first step when considering fertilisation. A soil test provides insights into the soil’s nutrient levels and pH, helping guide the type and amount of fertiliser required.
Fertilisers come in several varieties with different nutrients. The most critical nutrients for trees are macronutrients-nitrogen, phosphorus, and potassium. Micronutrients, including calcium, magnesium, and sulphur, also help. One might pick a fertiliser to remedy deficiencies based on the soil test.
Another point to consider is the timing of fertilisation. Generally, the best time to fertilise trees is during their active growth phases, usually in the spring or early fall. This ensures the tree can immediately utilise the added nutrients for growth and energy storage. Fertilising during a tree’s dormant phase can be less effective, as the tree’s metabolic activities are reduced, and it’s not actively seeking nutrients.
Even though it can promote trees, fertilising them should be done moderately. Over-fertilised trees grow quickly but weakly, making them more susceptible to diseases and pests. Too much fertiliser can run off, contaminating water sources and endangering other plants.
Inspect for Pests and Diseases
Trees stand tall and resilient, but like all living things, they can fall victim to pests and diseases. Regular inspection is essential to catch these problems early, ensuring that trees remain in optimal health and continue to enhance our landscapes with their beauty.
Pests can range from tiny aphids sucking sap from leaves to burrowing beetles that compromise the structural integrity of the trunk. Some pests are merely a nuisance, causing cosmetic damage, while others can severely affect a tree’s health or even lead to its death. For instance, if left unchecked, an infestation of emerald ash borers can quickly decimate an ash tree, turning it from a robust specimen to a brittle hazard.
However, fungi, bacteria, and viruses often cause sickness. They can cause discoloured leaves, trunk cankers, abnormal growth patterns, or tree health decline. Like pest control, early identification and response are crucial for tree diseases. A fungal infection can develop undetected, weakening the tree and making it more susceptible to other issues.
So, how does one go about inspecting trees for these problems?
The process starts with regular visual inspections. Make it a habit to observe your trees closely throughout the different seasons. Look for changes in leaf colour outside the typical autumn hues, check for patches of missing bark or areas that seem to be oozing sap, and look for unusual insect activity or webs and nests.
An inspection must consider both broad and micro perspectives. From afar, a tree’s canopy is thinning, indicating a problem. Looking closely, you might detect the signs of an insect infestation or a fungal infection.
However, not all diseases and pests are visible. Sometimes, the indicators are subtle, such as slow growth decrease or leaf yellowing. If this happens, get expert help. Tree specialists and arborists have the skills and equipment to diagnose and cure tree concerns.
Once an issue is found, respond quickly. Many pests and diseases can be addressed with pesticides, pruning, or care routine changes to improve tree health.
Protect the Trunk
At the core of every tree is its trunk, serving as the structural backbone and main conduit for water and nutrients. The central pillar supports the expansive canopy above and anchors the tree firmly below the ground. Given its significance, it’s imperative to protect the trunk from potential threats and damages that can compromise the health and stability of the entire tree.
With its bark, the trunk provides a natural defence against many external threats. However, it’s not impervious. Physical injuries are among the most common issues that tree trunks face. These can arise from various sources: lawnmowers bumping into the base, string trimmers slicing into the bark, or even bicycles chained regularly to young street trees. Each injury, no matter how minor it appears, creates an entry point for pathogens, pests, and diseases. Over time, these wounds can become avenues for decay, weakening the trunk and jeopardising the tree’s overall health.
Environmental stresses also pose a threat to tree trunks. For instance, during winter in colder climates, the phenomenon known as sunscald can occur. On warmer days, the sun heats the bark, stimulating activity. However, as temperatures drop rapidly in the evening, the suddenly active cells can freeze and die, leading to cracks in the bark. These injuries not only mark the appearance of the trunk but also make it vulnerable to infections and pests.
To protect trunks from physical injuries, it’s essential to be mindful when using lawn equipment near trees, especially young ones with tender bark. Creating a buffer zone, perhaps with mulch or protective guards, can keep mowers and trimmers at bay. Protective barriers can be invaluable for those living in urban settings, where trees often share space with pedestrians and vehicles. These shield the trunk from physical contact and serve as a visual reminder for people to treat the tree carefully.
Protective wraps can be used during the winter for environmental stresses like sunscald. These wraps, often made of burlap or other breathable materials, reflect sunlight and insulate the trunk, preventing the rapid temperature fluctuations that lead to damage.
However, while considering protection, it’s crucial to ensure that protective measures don’t inadvertently cause harm. For instance, wrapping a trunk too tightly or leaving a wrap on for too long can trap moisture, leading to rot or fungal infections.
Soil Compaction is a No-No
When envisioning the key components of tree health, most people might consider the obvious: sunlight, water, and nutrients. However, the state of the soil itself, particularly its structure and density, plays an indispensable role in ensuring a tree’s vitality. Among the many threats to this delicate balance is soil compaction, an often overlooked issue that can harm tree health.
Soil compaction refers to pressing soil particles together, reducing the pore spaces between them. This can occur for various reasons, including foot traffic, vehicular movement, construction activities, or regular yard maintenance. While compacted soil might seem like a minor inconvenience, its implications for trees are profound.
A healthy soil structure allows for the easy movement of water, air, and nutrients. Trees rely on these spaces for root expansion and access to the oxygen and water they need for growth. Compacted soil impedes this movement. The reduced permeability can cause water to pool on the surface, leading to root rot, or prevent water from reaching the roots entirely, causing drought-like conditions even in well-watered areas.
Furthermore, as roots find it challenging to penetrate compacted soil, their growth can become stunted or distorted. Instead of expanding outward, searching for nutrients, they might circle around, leading to girdling, where the roots or the tree trunk strangle. Such inhibited root growth reduces a tree’s stability and access to nutrients, making it more susceptible to environmental stresses and diseases.
Beyond the physical barriers it presents, compacted soil can also decrease beneficial soil organisms. Earthworms, fungi, and bacteria break down organic matter, aerate the soil, and facilitate nutrient absorption. These organisms might decline or disappear in compacted environments, reducing soil health.
Preventing and addressing soil compaction requires a blend of foresight and intervention. When planning landscaping or construction projects, it’s vital to minimise heavy equipment or materials’ contact with the soil around trees. Implementing pathways or designated walking areas can help direct foot traffic away from critical root zones. If compaction has already occurred, aeration techniques, such as vertical mulching or radial trenching, can help reintroduce spaces into the soil, improving its structure and health.
Know When to Call a Professional
Caring for trees is both an art and a science, blending keen observation with knowledge gleaned from years of experience and study. While passionate homeowners and garden enthusiasts can manage many aspects of tree care, there are moments when the expertise of a professional becomes indispensable. Recognising these moments can be the difference between the flourishing or faltering of a beloved tree.
One of the primary reasons to seek a professional’s insight is when you notice signs of disease or pest infestation that are unfamiliar or seem advanced. The world of tree diseases and pests is vast, and while some can be managed with simple interventions, others require specialised treatments or knowledge of lifecycle patterns. An arborist or tree care specialist brings expertise in identifying these issues and recommending the most effective and environmentally friendly solutions.
Another scenario that warrants professional intervention is when structural problems arise. Perhaps a tree is leaning precariously after a storm, or you’ve noticed large branches that seem weak or detached. Addressing these issues is not just about tree health; it’s also about safety. Falling branches or toppling trees can cause significant damage to property or, worse, pose direct threats to human life. Professionals can assess the structural integrity of a tree, suggest stabilising measures, or safely remove parts that pose immediate hazards.
While seemingly straightforward, pruning can benefit from an expert touch, especially for mature or tall trees. Improper pruning can lead to stunted growth, introduce diseases, or create imbalances that make the tree more susceptible to storm damage. Furthermore, pruning larger trees often involves climbing or using specialised equipment, which can be dangerous without the proper training and tools.
Root issues, often hidden beneath the surface, are another realm where professionals can offer invaluable insights. Whether it’s girdling roots, compacted soil, or problems stemming from construction damage, an expert can recommend interventions that might not be apparent to the casual observer.
Lastly, professionals are also valuable resources for preventive care. Regular consultations or check-ups, especially for older trees or those in urban environments, can help spot potential issues before they become severe problems. This proactive approach ensures the tree’s longevity and can save time and resources in the long run.

Frequently Asked Questions
Why is it important to avoid soil compaction around trees?
Soil compaction can hinder the movement of water, air, and nutrients to the tree roots. Compacted soil can lead to stunted root growth, reduced stability, and decreased soil health, ultimately affecting the overall vitality of the tree.
How often should I water my trees?
The watering frequency depends on the tree’s age, the soil type, and the climate. Young trees typically require more frequent watering until they establish their root systems. Avoid waterlogging the soil by maintaining a steady moisture level. Digging two inches below the soil surface and assessing the moisture content is a good indicator.
What’s the purpose of mulching around trees?
Mulch has several uses. It regulates soil temperature, compaction, weed growth, and moisture. Organic mulch decomposes, adding soil nutrients.
When is the best time to prune trees?
Although little trimming and deadwood removal can be done anytime, more extensive pruning should be done during the dormant season, usually late winter or early spring. This time reduces sap loss and disease transmission.
How do I know if my tree has a disease or pest problem?
Signs of diseases or pests can vary. Common indicators include discoloured or spotted leaves, oozing sap, unusual growth patterns, or a decline in the tree’s overall vitality. It’s best to consult a tree care professional or arborist for a detailed evaluation if unsure.
