Underwatering
Most likelyHow to tell: The leaves feel dry and brittle, and the soil is bone dry several inches down.
What to do: Give the tree a deep soak, ensuring water reaches 12 to 18 inches into the soil. Repeat this every 7 to 14 days during dry spells.
Phytophthora root rot
PossibleHow to tell: The tree wilts even when the soil is moist, and the foliage may look sparse or off color.
What to do: Improve soil drainage immediately by amending the surrounding area with organic matter. Avoid overwatering, as wet feet encourage this pathogen.
