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.
When to worry
A few brown tips are common in late summer heat. Worry if the browning spreads rapidly or affects the entire canopy.
Stopping it coming back
Maintain a consistent watering schedule during the first few years of the tree's life to help it establish a deep root system.

Questions people ask
- Should I trim off the brown tips?
- You can trim them for aesthetic reasons, but it does not help the tree recover. Just make sure to use clean, sharp shears.
- How much water does a young tree need?
- A young tree needs a deep soaking that reaches the roots. Aim for enough water to moisten the soil to a depth of 12 inches.
