What to do: Move the plant to the sunniest spot in your home or garden. If indoors, place it directly in a south facing window.
Poor Air Circulation

When to worry
Worry if the plant is losing leaves rapidly from the top down. It is normal for a few old leaves at the base to drop as the plant matures.
Stopping it coming back
Provide plenty of direct sun and ensure the plant has space for air to move around its branches.

Questions people ask
- Will the leaves grow back where they fell off?
- Lavender does not typically regrow foliage on old, woody stems. You can trim back the green, leafy growth to encourage new shoots, but avoid cutting into bare old wood, as it often will not regrow.
- Is leaf drop a sign of overwatering?
- It can be, as overwatering leads to root rot which prevents the plant from taking up nutrients. Check the soil for sogginess.
