Troubleshooting
Munstead Lavender problems — and how to fix them
Munstead Lavender (Lavandula angustifolia 'Munstead') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Wet-soil root rot
Most failures trace to soggy roots; provide sharp drainage and keep it dry, especially through winter, rather than feeding or fussing over it.
Legginess without trimming
Unsheared plants go woody and open; trim after the first flush, taking care never to cut into bare old wood, which usually won't regrow.
Sparse bloom in low light
Insufficient sun yields weak growth and few spikes; relocate to the sunniest, airiest spot for a full flowering.
Fungal dieback in damp air
High humidity and crowding cause grey, dying patches; space plants well and water at the base to keep foliage dry.
