Pocket BotanistCheck these first
- Check if the tree was recently moved.
- Feel the soil to see if it is too dry or too wet.
- Look for signs of pests on the fallen leaves.
Likely causes
Sudden environmental change
Most likelyHow to tell: The tree drops leaves shortly after being moved to a new spot or after a temperature shift. It is reacting to the change in light intensity.
What to do: Keep the tree in a spot with consistent full sun. Avoid moving it frequently so it can acclimate to its surroundings.
Inconsistent watering
PossibleHow to tell: The leaves turn yellow or brown before falling off. The soil may be bone dry for too long or constantly soaked.
What to do: Establish a rhythm of watering every 5 to 10 days. Water deeply until it runs out the bottom, then wait for the top few centimeters to dry.
When to worry
It is normal for a few old leaves to drop occasionally. You should worry if the tree is losing many leaves at once or if the new growth is falling off.
Stopping it coming back
Maintain a stable environment with plenty of direct sunlight and consistent watering habits.
