Is it normal for my tree to lose leaves in July?

No, that is a sign of stress, likely from drought or disease. Check your soil moisture and inspect the leaves for spots.

How much water does my Green Ash need?

Young trees need consistent moisture, so water deeply every 7 to 14 days. Established trees are more tolerant but still benefit from deep watering during dry spells.

Likely causes

Drought Stress
Most likely
How to tell: Leaves may turn yellow or brown and fall off during the hottest part of summer. The soil will feel dry and hard several inches down.
What to do: Water the tree deeply once every 7 to 14 days, ensuring the water reaches the root zone. Add a 3 inch layer of mulch around the base to hold moisture in.
Severe Anthracnose
Possible
How to tell: Leaves drop early in the season after showing dark spots or curling. This often happens after a very wet spring.
What to do: Clean up all fallen leaves immediately to prevent the fungus from overwintering. Ensure the tree is not crowded by other plants to allow for better drying.

When to worry

If the tree loses most of its leaves in mid-summer, it is a sign of significant stress. It is normal for a tree to drop some leaves during a natural autumn transition.

Stopping it coming back

Maintain a consistent watering schedule during the first few years of growth. Keep the base of the tree clear of weeds and debris to reduce disease pressure.
