Likely causes
Heat Stress
Most likelyHow to tell: The leaves droop and curl during the hottest part of the day but recover at night. This happens when the tree loses water faster than it can take it up.
What to do: Move the tree to a spot with more dappled shade during the afternoon. Mulch the base of the tree to help keep the roots cool and moist.
Verticillium Wilt
PossibleHow to tell: Branches wilt and droop suddenly, often on just one side of the tree. The leaves may turn brown or yellow and fall off prematurely.
What to do: Prune out the affected branches, sterilizing your shears with alcohol between every cut. Unfortunately, there is no cure, so focus on keeping the tree hydrated to help it fight the infection.

When to worry
Drooping during a hot afternoon is usually temporary and normal. Worry if the drooping persists overnight or if specific branches stay wilted and eventually turn brittle.
Stopping it coming back
Provide adequate afternoon shade and avoid overwatering, which can stress the roots and make the tree vulnerable to soil pathogens.

Questions people ask
- Can I save a tree with Verticillium wilt?
- It is very difficult to cure. Pruning the infected parts can slow it down, but the fungus lives in the soil.
- Does my tree need more water if it droops?
- Only if the soil is dry. If the soil is wet, adding more water will only make the root stress worse.
