overwatering and Lavender
Quick answer
If overwatering is what's going on with your Lavender, the most likely cause is: Lavender is adapted to rocky, lean Mediterranean soils. In heavy clay or high-organic soil, moisture is retained too long, causing the fine roots to die from lack of oxygen (asphyxiation).
Start here:
- 1. If leaves turn grey-brown and soft, unpot and check for black, mushy roots.
- 2. Amend soil with 50% grit, sand, or pea gravel to ensure instant drainage.
