What to do: Maintain a consistent watering schedule so the soil never dries out completely. Avoid heavy nitrogen fertilizers that can interfere with calcium uptake.

When to worry

Stopping it coming back
Keep soil moisture steady and avoid sudden swings in watering frequency.

Questions people ask
