Pocket BotanistCheck these first
- Feel the soil to see if it is dry several inches down.
- Check if the browning is widespread or just on the tips.
- Consider if road salt was used near the tree recently.
Likely causes
Drought Stress
Most likelyHow to tell: The leaves feel dry and brittle, and the browning starts at the very tips or edges. This is common during hot, dry spells.
What to do: Water the tree deeply every 7 to 14 days during dry periods. Ensure the water reaches the root zone by soaking the soil slowly.
Salt Damage
PossibleHow to tell: The tips turn brown and the leaves may curl slightly after a winter where road salt was used nearby. The damage usually appears in spring.
What to do: Flush the soil around the tree with plenty of fresh water in the spring to wash away excess salts. Apply a layer of organic mulch to protect the roots.
