lavender 'Richard Gray'

Prefers a well-drained neutral to alkaline soil but tolerates acidic conditions. In heavy soil improve drainage as lavender does not tolerate waterlogging. Potash will encourage flowering but high nitrogen fertilisers and manure will result in floppy plants. See lavender cultivation for further advice

Pruning group 10, after flowering
