- Look for pink pustules on the bark which indicate coral spot.
Likely causes
Verticillium wilt
PossibleHow to tell: Leaves wilt and drop suddenly, often on just one side of the tree. You may see dark streaks inside the wood if you cut a small twig.
What to do: Prune out affected branches well below the damage, sterilizing your tools between cuts. Keep the tree healthy with proper water and avoid wounding the roots.
Severe heat stress
PossibleHow to tell: The leaves turn brown or yellow and fall off during a heatwave. The tree is shedding foliage to reduce water loss.
What to do: Provide deep, slow watering at the base of the tree. Add a thick layer of mulch to insulate the root zone from the heat.

Questions people ask
- Is leaf drop always a sign of death?
- Not necessarily, as it is often a defense mechanism against stress. If the tree is otherwise healthy, it will likely recover next season.
- Does this tree flower?
- Yes, it produces beautiful pink flowers directly on the branches in spring. It needs a sunny spot and a few years of growth to start blooming reliably.
