About Lavender
Lavender needs excellent drainage above all — it will rot in wet heavy soil even in a suitable zone.
Plant in the sandiest most well-drained soil you have. Raised beds or containers work well. Cut back by half after flowering. English lavender (L. angustifolia) is the hardiest for cold zones.
