Likely causes
Improper watering
Most likelyHow to tell: Leaves turn yellow or brown before falling off. The soil may be bone dry or soggy for days.
What to do: Water deeply once every 7 to 14 days, ensuring the soil is moist but not swampy. Increase frequency during hot summer weeks.
Plum curculio damage
PossibleHow to tell: Fruit drops prematurely along with some leaves. You may see crescent shaped scars on the remaining fruit.
What to do: Pick up and destroy all fallen fruit immediately to break the pest cycle. Use a fruit tree spray labeled for curculio if the infestation is heavy.
When to worry
It is normal for a few leaves to drop in late autumn as the tree prepares for winter. Sudden, heavy leaf drop in summer is a sign of stress.
Stopping it coming back
Maintain a consistent watering schedule and keep the area under the tree clear of fallen fruit and debris.
