Summer in Hampton Roads is intense…and not just for people. If you have large pine trees on your property, you’ve probably noticed them struggling during stretches of extreme heat. As certified arborists who work with mature pines every day, we’ve seen firsthand how high temperatures and drought conditions can stress these towering trees. Understanding the risks and how to respond can go a long way toward keeping your pines healthy all season long.
Understanding the Risks
Large pine trees may look strong and self-sufficient, but prolonged heat puts them under significant stress. Here’s what happens:
- Reduced Moisture Intake: Pine roots need consistent moisture to function. In hot, dry conditions, water evaporates quickly from the soil, making it harder for roots to absorb what they need.
- Cracked or Compacted Soil: Heat and dryness can harden the soil, reducing oxygen flow to roots and further limiting water absorption.
- Brown Needles and Needle Drop: A stressed pine may start shedding its older needles or show browning at the tips. This is a sign the tree is conserving energy.
What You Can Do to Help
Fortunately, there are proactive steps you can take to support your large pine trees through the summer months:
- Deep Watering Is Key: Instead of light, frequent watering, opt for deep watering every 7–10 days. This encourages deep root growth and keeps moisture where the tree needs it most. Focus on the root zone, not the trunk, and water slowly to prevent runoff.
- Mulch the Right Way: A 2- to 4-inch layer of organic mulch around the base of the tree (but not touching the trunk) helps retain soil moisture and regulate temperature.
- Watch for Warning Signs: Look for early indicators of stress like discolored needles, premature needle drop, or visible pests. Catching issues early makes treatment more effective and recovery more likely.
- Avoid Pruning in Extreme Heat: Pruning during peak summer heat can increase stress and exposure. If pruning is needed, wait until temperatures cool, ideally in late summer or fall.
- Schedule a Tree Health Evaluation: A professional arborist can assess your pines for signs of drought stress. With expert insight, you can make informed decisions about care or, in some cases, removal.
