Pocket BotanistCheck these first
- Check the soil moisture at a depth of 3 inches.
- Look for signs of recent heat waves or high winds.
- Check if the tree is near a treated driveway or road.
Likely causes
Drought stress
Most likelyHow to tell: The tips of the leaves become dry, brittle, and brown during hot, dry weather. The soil around the base feels dusty and dry.
What to do: Water the tree deeply once every 7 to 10 days during dry spells. Apply a 2 to 3 inch layer of mulch around the base to hold in moisture.
Salt accumulation
PossibleHow to tell: Brown tips appear even when the soil feels moist. This often happens if the tree is near a sidewalk or road treated with salt in winter.
What to do: Flush the soil with a large volume of water to leach salts away from the root zone. Avoid using de-icing salts near the tree in the future.

Stopping it coming back
