Troubleshooting
Tenerife Lavender problems — and how to fix them
Tenerife Lavender (Lavandula buchii) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot (from overwatering or winter wet)
Sitting in moist or waterlogged soil — especially in cool temperatures — rapidly induces root and crown rot. This is the most common cause of plant failure; ensure perfect drainage and drastically reduce watering from October to March.
Aphids and whitefly
Young shoot tips attract aphid colonies, and whitefly can be a persistent problem on container plants overwintered under glass. Treat with insecticidal soap or a neem-based spray; introduce biological controls such as Encarsia formosa in a glasshouse setting.
