Likely causes
Salt accumulation
PossibleHow to tell: The edges and tips of the leaves turn brown and crispy while the rest of the leaf stays green. This often happens after a harsh winter where road salt was used nearby.
What to do: Flush the soil around the root zone with large amounts of water to leach out excess salts. Avoid using chemical fertilizers near the tree during the summer.
Heat stress
PossibleHow to tell: Tips brown during periods of extreme heat and direct sun exposure. The leaves may feel brittle to the touch.
What to do: Provide supplemental water during heat waves to keep the root zone cool. Ensure the tree has adequate mulch to protect the roots from surface heat.
