Pocket Botanist
Check these first
- Feel the soil moisture at least 6 inches deep.
- Check for signs of recent root disturbance.
- Observe if the wilting recovers overnight.
Likely causes
Severe drought
Most likelyHow to tell: The leaves look wilted and limp, especially during the hottest part of the day. The soil around the root zone feels bone dry several inches down.
What to do: Give the tree a deep soak by running a hose at the base for 30 to 60 minutes. Ensure the water penetrates at least 12 inches into the soil to reach the deep roots.
Transplant shock
PossibleHow to tell: This happens if the tree was recently planted and is struggling to establish its root system. The foliage wilts despite the soil feeling damp.
What to do: Keep the soil consistently moist but not soggy for the first year. Apply a 3 inch layer of mulch around the base to retain moisture and protect the roots.

When to worry
If the tree remains wilted after a deep watering and a cool night, the root system may be damaged. It is normal for leaves to curl slightly during extreme heat waves.
Stopping it coming back
Provide deep, infrequent waterings during the first two years to encourage a strong, drought tolerant root system.

Questions people ask
- Should I fertilize a drooping tree?
- No, avoid fertilizing a stressed tree. It can push the plant to grow when it needs to focus on root recovery.
- Does my tree need daily water?
- Only if it was planted within the last few weeks. Once established, deep watering every 10 to 14 days is plenty.
