When summer rolls in with its soaring temperatures and dry spells, your trees can feel the stress just as much as your lawn and garden. Proper tree care during the summer months is crucial for maintaining healthy growth, preventing disease, and preparing for the seasons ahead. Whether you have young saplings or mature trees, these summer tree care tips will help ensure they stay strong and beautiful all season long.
1. Water Wisely and Deeply
Summer heat can lead to drought stress, especially for young or newly planted trees.
- Water early in the morning or late in the evening to reduce evaporation.
- Focus on deep watering at the root zone rather than frequent, shallow watering.
- Use a soaker hose or drip irrigation to slowly saturate the soil.
- Mature trees typically need 1 inch of water per week, but this may increase during extreme heat.
2. Apply Mulch to Conserve Moisture
Mulching is one of the easiest and most effective ways to protect your trees in summer.
- Spread 2–4 inches of organic mulch (like bark or wood chips) around the base of the tree.
- Keep mulch 2–3 inches away from the trunk to prevent rot and pests.
- Mulch helps retain moisture, regulate soil temperature, and suppress weeds.
3. Inspect for Pests and Disease
Warm weather accelerates the activity of many tree pests and pathogens.
- Regularly inspect leaves, bark, and branches for signs of insects, fungus, or disease.
- Watch for symptoms like wilting, leaf discoloration, holes, or sticky residue.
- Early detection is key—consult a certified arborist if you notice anything unusual.
4. Prune with Purpose
Summer pruning can be beneficial if done correctly.
- Remove dead, damaged, or diseased branches to prevent further problems.
- Light structural pruning can improve airflow and reduce the risk of storm damage.
5. Fertilize Carefully
Fertilization needs vary depending on your tree species and soil health.
- Conduct a soil test before applying any fertilizer.
- Avoid over-fertilizing in summer, as it can lead to rapid, weak growth and increased water needs.
- Opt for a slow-release fertilizer if needed, and water thoroughly afterward.
6. Prepare for Summer Storms
Heavy rain, wind, and lightning can take a toll on your trees.
- Install cables or bolts and prune high-risk branches. (See our Tree Cabling and Bracing services)
- Stake young trees if necessary.
- Clear deadwood that could fall during storms.
Your trees are long-term investments in beauty, shade, and property value. With a little extra care during the summer months, you can help them thrive through the heat and set them up for continued health year-round. Whether you’re a home gardener or a property manager, following these summer tree care tips is a smart way to protect your green assets.
