Check these first

- Inspect the trunk base for signs of rot or standing water.
- Check the underside of leaves for any signs of pests.
Likely causes
Poor Drainage
Most likelyHow to tell: The soil stays soggy for days after watering and the leaves turn yellow before falling off. You might notice a sour smell near the base of the tree.
What to do: Stop watering immediately and check if the soil is heavy clay. If the area does not drain well, you may need to divert water away from the root zone. Do not add mulch directly against the trunk.
Summer Drought Stress
PossibleHow to tell: Leaves curl and turn brittle before dropping during the hottest months. The tree looks generally wilted even in the morning.
What to do: Provide a deep, slow soak once every 14 days during the first 3 years of growth. Once established, the tree prefers to stay dry, so avoid frequent shallow watering.
