Summers in Richmond Hill, Ontario can bring soaring temperatures and prolonged dry periods. While sunshine is great for outdoor activities, it can put significant stress on your trees—especially young, newly planted, or shallow-rooted species. Drought and heat stress can weaken trees, making them more vulnerable to pests, diseases, and even long-term decline.
At Castor Tree Care Services, we believe proactive care is the key to keeping your trees healthy and thriving all summer. Here are practical watering, mulching, and monitoring tips to protect your landscape during hot Canadian summers.
1. Watering Tips to Keep Your Trees Hydrated
-
Water Deeply, Not Frequently
Instead of light, daily watering, aim for slow, deep soaks that reach the root zone (about 6–12 inches deep). This encourages roots to grow deeper, increasing drought resistance.
-
Best Time to Water
Water early in the morning or late evening to reduce evaporation and allow trees to absorb moisture efficiently.
-
How Much to Water
A general rule: provide about 10–15 gallons of water per inch of trunk diameter once a week during dry spells. Use a soaker hose or drip irrigation for even distribution.
2. Mulching to Conserve Soil Moisture
-
Apply Organic Mulch
Spread 2–4 inches of organic mulch (wood chips, shredded bark, or compost) around the tree’s base, keeping it 3–6 inches away from the trunk to prevent rot.
-
Benefits of Mulching
- Reduces soil moisture loss
- Moderates soil temperature
- Suppresses weed competition
- Improves soil health over time
3. Monitoring and Early Detection of Heat Stress
-
Signs of Drought Stress
Look for wilted, curling, or yellowing leaves, leaf scorch (brown edges), or premature leaf drop.
-
Check Soil Moisture
Use a moisture meter or simply dig a small hole near the root zone. If the soil feels dry 4–6 inches down, it’s time to water.
-
Inspect for Pests and Disease
Stressed trees are more vulnerable to insects and fungal infections. Regularly inspect bark, leaves, and branches for changes.
4. Additional Summer Tree Care Tips
-
Avoid Heavy Pruning
Pruning in extreme heat can stress trees further. Limit cuts to dead, damaged, or diseased branches.
-
Protect Young Trees
Newly planted trees have shallower roots and need extra attention. Increase watering frequency during heatwaves.
-
Consider Drought-Resistant Species
If planting new trees, choose varieties adapted to Ontario’s climate and capable of withstanding dry periods.
