How to Care for Mature Trees: 5 Essential Tips

Mature trees are more than just part of your landscape. They offer shade, enhance curb appeal, and can even increase property value. But without proper care, trees can decline in health and pose serious safety risks to your space and the surrounding structures. Whether you're a homeowner or a property manager, knowing how to care for mature trees is fundamental to preventing accidents and keeping property exterior in top shape.  

In this blog, we’ll walk you through four key tree maintenance tips and show you how to tell if your trees are truly thriving in Brockville.  

1. Pruning for Safety and Tree Health 

Pruning isn’t just about aesthetics; it’s a critical part of tree care. Removing dead, damaged, or diseased branches helps prevent accidents and promotes healthy growth. Pruning also improves airflow and light penetration, which can reduce the risk of fungal infections. For large or complex trees, it’s best to hire a professional to ensure safe and effective pruning. 

2. Mulching: Protecting the Roots 

Mulch acts like a protective blanket for your tree’s root system. It can contribute to moisture retention, soil temperature regulation and weed suppression.  We recommend that you spread a 2-to-4-inch layer of organic mulch around the base of the tree, making sure to leave a few inches of space between the mulch and the trunk to avoid rot. This can greatly contribute to the overall health of your mature tree. 

3. Fertilization & Soil Care 

Over time, soil can lose essential nutrients, which will directly affect the health and appearance of your tree. Fertilizing mature trees can help replenish these nutrients and support strong growth. However, not all trees need the same treatment. A soil test can reveal what’s missing and guide you toward the right fertilization plan.  

4. Watering Wisely 

Even mature trees need water, especially during hot, dry periods. Properly watered trees can develop deeper roots, which makes them more resilient to drought. Focus on watering the area beneath the canopy and avoid frequent shallow watering, which can lead to weak roots. A slow, deep soak every few weeks is often more beneficial than daily watering. 

5. Monitoring for Pests and Disease 

Mature trees can be vulnerable to pests like borers, aphids, or fungal infections. Early detection is key. Watch for signs such as discolored leaves, unusual growths, or bark damage. If you notice anything unusual, it’s best to consult a certified arborist before the issue spreads. 

How Do You Know If a Mature Tree Is Healthy? 

While vibrant leaves and strong branches are good signs, some tree health issues aren’t visible to the untrained eye. Problems such as internal decay and pest infestations can be difficult to detect until it's too late. That’s why regular inspections by a certified arborist are so important. 

An experienced arborist can assess your tree’s condition, identify potential risks, and recommend proactive care strategies. If you're unsure about the health of your trees, scheduling a professional assessment is the safest and smartest step to take.
