- Check if the plant is sitting in a saucer of water.
Likely causes
Poor drainage
Most likelyHow to tell: The soil feels soggy or swampy even days after watering. The leaves may turn yellow or brown before dropping off.
What to do: Stop watering immediately and allow the top 2 to 3 inches of soil to dry out completely. If the plant is in a container, ensure the drainage holes are not blocked.
Overwatering
PossibleHow to tell: The plant shows signs of wilting despite the soil being damp. The roots may appear mushy or dark if you dig down slightly.
What to do: Adjust your schedule to water only when the top inch of soil is dry. Ensure you are watering deeply but infrequently, usually every 7 to 14 days.

When to worry
If the stems feel soft or the plant is collapsing, the damage may be too far gone. If only a few leaves are affected, you can likely save it by correcting the moisture.
Stopping it coming back
Always check the soil moisture before adding more water. Use well draining soil mixes if you are growing your Bottlebrush in a container.

- Only repot if the soil is heavy and holding too much water. If the roots are mushy, trim away the decayed parts before replanting in fresh, airy soil.
- How often should I water?
- Water every 7 to 14 days, but always test the soil first. If it is still damp, wait a few more days.
