Likely causes
Drought Stress
Most likelyHow to tell: Leaves turn brown or crispy at the edges before falling off. The soil feels dry and cracked.
What to do: Water the tree deeply every 7 to 14 days during dry spells. Ensure the water reaches at least 12 inches into the soil.
Heat Stress
PossibleHow to tell: Leaves wilt and drop during extreme heat waves. The tree looks generally tired despite regular watering.
What to do: Apply a 3 inch layer of mulch around the base to keep the roots cool. Avoid pruning during the hottest part of the summer.
When to worry
It is normal for leaves to drop in late autumn. Worry if the tree loses a significant amount of green leaves during the peak of summer.
Stopping it coming back
Keep the tree well watered during dry periods and use mulch to regulate soil temperature.

Questions people ask
- Is my tree dying if it drops leaves in July?
- It is likely just stressed. Provide deep, consistent water and it should recover.
- Does mulch help with leaf drop?
- Yes, mulch keeps the roots cool and helps the soil hold onto moisture longer. This prevents the stress that leads to early leaf drop.
