Pocket Botanist
Check these first
- Check the soil moisture level with your finger or a trowel.
- Inspect the base of the trunk for any signs of oozing or sunken bark.
- Look at the surrounding ground to see if water is pooling after rain.
Likely causes
Severe dehydration
Most likelyHow to tell: The leaves look limp and thin, and the soil feels bone dry several inches down.
What to do: Give the tree a deep soak by running a hose at the base for 30 to 60 minutes. Apply a layer of mulch around the base to help the soil retain moisture.
Phytophthora root rot
PossibleHow to tell: The tree wilts even when the soil is wet, and you might see dark, sunken lesions on the lower trunk.
What to do: Improve soil drainage immediately by diverting excess water away from the root zone. Unfortunately, there is no cure for established root rot, so focus on keeping the tree as healthy as possible.

When to worry
Worry if the drooping persists after a deep watering or if you see visible cankers on the trunk. It is normal for young trees to look a bit tired during the hottest part of a summer afternoon.
Stopping it coming back
Ensure your tree is planted in well draining soil and water young trees consistently during their first two years.

Questions people ask
- Should I fertilize a drooping tree?
- No, avoid fertilizing a stressed tree. It needs to focus its energy on root recovery rather than new growth.
- Can a drooping tree recover?
- Yes, if it is just thirsty, it will perk up within a day of watering. If the cause is root rot, recovery is much harder.
