- Avoid digging under and around trees so you don’t disturb the roots
- Don’t do any heavy pruning. However, it’s OK to remove broken, dead, insect-infested or diseased branches.
- Keep an eye out for insect pests and disease, because drought-stressed trees are more vulnerable to attack.
- Avoid using high-nitrogen lawn fertilizers under trees, and never use weed-and-feed products, which can harm tree roots.
