With the extreme heat, dry weather, and blazing sun of Arizona summers, tree maintenance is more crucial than ever. Your trees can have a hard time surviving the season if they aren’t properly cared for. The good news? Protecting your trees and maintaining their health throughout the summer can be achieved with a little forethought in the early spring. Here are some tips for keeping your trees robust, hydrated, and healthy throughout the year’s hottest months.
1. Deep Watering for Stronger Roots 💧

Arizona’s dry heat quickly depletes soil moisture, leaving trees thirsty and stressed. Shallow watering won’t cut it! Instead, use deep watering techniques to help roots grow deeper into the soil, where moisture lasts longer.
✅ How to Water Properly:
- Water in the early morning or late evening to prevent evaporation.
- Use a slow-drip irrigation system or soaker hose to ensure deep penetration.
- Water at the drip line (the area beneath the outer canopy, not at the trunk).
- Water twice a week for young trees and once a week for mature trees.

2. Mulch to Lock in Moisture & Keep Roots Cool 🌿
Mulching is one of the easiest ways to protect your trees from extreme heat. It helps the soil retain moisture, stay cool, and reduce weed competition.
✅ Best Mulching Practices:
- Apply 2-4 inches of organic mulch (wood chips, bark, or leaves) around the base.
- Keep mulch a few inches away from the trunk to prevent rot.
- Replenish mulch throughout the season as it breaks down.

3. Prune Wisely to Reduce Stress ✂️

Pruning is essential for maintaining tree structure and health, but over-pruning in the heat can leave trees vulnerable to sun damage.
✅ What to Prune in Spring:
- Remove dead, diseased, or broken branches to prevent hazards.
- Thin out crowded branches to improve airflow.
- Trim away branches growing too close to structures for safety.
Avoid heavy pruning in summer since exposed branches can suffer from sunburn. Our Phoenix tree service experts provide professional pruning to keep your trees balanced and protected.

4. Protect Young & Sensitive Trees from Sunburn ☀️
Yes, trees can get sunburned! The harsh Arizona sun can scorch tree bark, causing cracks and weakening the tree’s structure.
✅ How to Prevent Sun Damage:
- Wrap young tree trunks with protective tree wrap or cloth.
- Use white latex paint diluted with water as a natural sunblock for thin-barked trees.
- Provide temporary shade structures for newly planted trees.

5. Fertilize for Strength & Resilience 🌱
Just like we need nutrients to stay strong, trees need fertilization to build resistance against heat stress and drought. Spring is the perfect time to boost tree health with the right nutrients.
✅ Best Fertilization Practices:
- Apply slow-release fertilizer with essential nutrients like nitrogen, phosphorus, and potassium.
- Fertilize before summer hits to help trees store nutrients.
- Use organic compost to improve soil quality.
