When to worry
It is normal for a Bottlebrush to shed a few old, inner leaves as it grows. You should worry if the leaf drop is sudden, widespread, or accompanied by visible pests.
Stopping it coming back
Inspect your plant regularly for pests and keep it in a consistent, full sun location to minimize stress.

Questions people ask
- Are these bumps on my plant harmful?
- Yes, those are scale insects that suck sap from your plant, which leads to leaf drop and stunted growth. You should treat them as soon as you spot them.
- Will the leaves grow back?
- Once the underlying issue is fixed, the plant will produce new growth. It will not grow leaves back on the exact same spot on the stem, but it will fill out over time.
