Check these first
- Feel the soil to see if it is soggy or dry.
- Check the base of the trunk for any signs of rot or discoloration.
- Look at the surrounding plants to see if they are also wilting.
Likely causes
Phytophthora root rot
PossibleHow to tell: The foliage wilts and droops even when the soil is moist. The roots will appear dark, mushy, or decayed instead of firm and white.
What to do: If the roots are rotted, the plant is likely beyond saving. Improve drainage in your garden beds for future plantings by using raised mounds or sandy soil.
Severe dehydration
PossibleHow to tell: The entire plant looks limp and the leaves lose their stiffness. This happens if the tree has gone too long without a deep soak.
What to do: Give the tree a slow, deep watering to saturate the entire root ball. Monitor the soil over the next few days to ensure it recovers its turgor.

When to worry
Drooping is a serious sign for a Banksia and often indicates that the root system is failing. If the soil is wet and the plant is drooping, it is likely a critical situation.
Stopping it coming back
Plant in well draining soil and avoid overwatering, especially in heavy clay conditions.

Questions people ask
- Can I save a drooping Banksia?
- If it is just thirsty, a deep drink will help it bounce back within a day. If it is root rot, recovery is very difficult.
- Does heat cause drooping?
- Banksias are heat tolerant, but extreme heat combined with dry soil can cause temporary wilting. Water deeply in the early morning to help it handle the heat.
