Wood Forget-me-not problems — and how to fix them
Wood Forget-me-not (Myosotis sylvatica) 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.
Powdery mildew
A common late-season problem, especially in dry, warm conditions; improve air circulation by thinning plants and water at the base rather than overhead. Affected plants can usually be left to set seed before removing.
Grey mould (Botrytis cinerea)
Dense, congested plantings in cool, damp springs are prone to grey mould collapse; thin seedlings to at least 15 cm apart and remove dead stems promptly to reduce spore load.
