Basic Tree Maintenance Tips for Young and Mature Trees

Trees aren’t merely aesthetically pleasing but crucial in sustaining our environment. When we care for them, they reward us with many benefits. This is why tree maintenance is so crucial-it’s not just about the trees; it’s about the health and vitality of our surroundings.

The basics of tree care include watering, pruning, and ensuring adequate nutrients reach the trees’ root systems. However, how you carry out these tasks can vary depending on a tree’s growth stage. Let’s review some tree maintenance tips for young and mature trees.

Young Trees

• Watering

Regular watering is important for the growth of young trees. It helps develop a robust root system. A well-established root system is critical to the tree’s future success. The soil should be kept slightly damp but completely soaked or pooling water around the tree’s base (too much water can drown out the roots). A good rule of thumb is to water young trees 4-6 inches below the soil surface at least once weekly.

• Nutrients

In urban areas like Toronto, trees face unique challenges. Due to soil compaction and limited space, they often need help getting nutrients. This is where we can step in by making soil amendments to ensure trees get the nutrition they need to thrive. An air spade can be a valuable tool in this process, helping to improve aeration, water retention, and drainage around young trees.

It is also essential to keep the weeds at bay. Weeds and other vegetation compete with the tree’s roots for water and soil nutrients. One easy, effective, and environmentally friendly way to prevent weeds from growing is to add mulch around the base of a young tree. Mulch also offers insulation for the roots in the cold winter months.

• Pruning

Pruning saplings and young trees is a significant part of caring for them. However, due to their vulnerability, it’s best to leave pruning to experienced professionals. This ensures that the tree’s health and growth are in safe hands, giving you the confidence that your tree is getting the best care.

Newly planted trees should solely undergo pruning to eliminate diseased or damaged branches, particularly during the initial few years. Proper pruning techniques protect a tree’s structural integrity and encourage robust and healthy growth. Improper pruning can compromise a sapling’s ability to grow a balanced branch scaffold.

Mature Trees

Mature trees are incredible assets. They provide shade and shield from the wind while contributing immeasurable beauty to our surroundings. Like young trees, they require regular care to ensure their many benefits remain. While the same primary care principles apply to young and old trees, mature trees require a slightly different approach.

• Watering

Mature trees already have well-established root systems, so their watering needs are much different than those of saplings. If there has yet to be adequate rainfall in the area, they only need to be watered once per month.

• Nutrients

Mature trees often face nutrient deficiency issues related to soil compaction. Constant traffic over the critical root zone can easily compact the soil and prevent essential nutrients from reaching the roots. Aeration, fertilizers, and bio-stimulants offer solutions to this problem.

Aeration promotes the absorption of nutrients and is best done in spring or fall. It creates air pockets (macropores) in the soil, allowing nutrients (and water) to access the roots more easily.

Biostimulants and fertilizers both provide additional nutrients for the roots to absorb.

Biostimulants are administered to the soil, enveloping the crucial root area of a mature tree, to enhance the uptake of essential nutrients and facilitate robust and vigorous growth. Fertilizers tend to have higher nitrogen content, which can shock mature trees, making biostimulants a gentler option.

• Pruning

Mature trees also require pruning to maintain health. Pruning should be implemented to remove diseased, damaged, and dead branches—just like young trees. However, mature trees may also benefit from corrective trimming, such as weight reduction pruning.

Other things to consider:

Young trees are particularly susceptible when exposed to the elements. Maple and poplar trees, for example, often experience sunscald in the winter months. Evergreens more often suffer from winter drying and damage from salt exposure. Tree wrap or burlap can be installed to protect young trees from winter damage.

Managing diseases and pests is equally crucial for both young and mature trees. From wood-boring insects to fungal and bacterial infections, trees face a wide variety of threats to their health. Preventative measures can and should be taken to properly mitigate and treat the disease. For example, tree injections are an effective way to prevent insect infestations and fungal infections. You can think of them as vaccines for trees. Tree injections are incredibly efficient at getting critical treatment to all parts of the tree because they are injected directly into the inner layer of the tree, which is responsible for carrying essential nutrients throughout.

Staking is another maintenance task that may be considered for young trees. A newly planted tree can be staked if there is reason to believe it needs protection against damage in high-traffic areas (i.e. areas where lawn-mowers or weed trimmers are being used) or if they are having a difficult time establishing a robust root system (i.e. when a tree is planted on a hillside). If you choose to stake a newly planted tree, staking should be removed after the first year of growth to prevent permanent damage.

Installing cabling and bracing systems for mature trees is a similar intervention to staking. When a tree’s structural integrity becomes compromised (but not so much as to require complete removal), it may benefit from the reinforced stability of a cabling and bracing system.

The Bottom Line

Tree maintenance is essential for all trees, from saplings to old trees. You should be able to enjoy all the benefits trees offer for many years to come as long as you ensure the basic needs of watering, pruning, and nutrition are met.
