The RHS advises lavender “prefers poor, dry or moderately fertile soil, including chalky and alkaline soils.
“Lavender will not thrive in heavy clay soil or any soil that becomes waterlogged over winter.”
How to plant
Once you are sue you have the right conditions, dig over any free-draining soil and remove the weeds.
The RHS says: “If your soil is heavy, plant on a 20-30cm (8in-1ft) mound, ridge or in a raised bed where the roots will not sit in wet soil.”
