Hidcote Lavender problems — and how to fix them
Hidcote Lavender (Lavandula angustifolia 'Hidcote') 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 (Phytophthora/Pythium)
The leading cause of death; caused by waterlogged or poorly drained soil, especially in winter. Improve drainage with grit and avoid planting in clay hollows.
Botrytis (grey mould)
Grey fluffy growth develops on foliage in humid, overcast conditions or where plants are crowded. Improve air circulation by spacing plants at least 45 cm apart and hard-prune in late summer.
