Nemesia strumosa 'Poetry Blue' problems — and how to fix them
Nemesia strumosa 'Poetry Blue' (Nemesia strumosa 'Poetry Blue') 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.
Flowering collapses in heat and drought
Hot, dry conditions make Nemesia stop blooming and go leggy fast. Keep it watered, shear back by a third, and bloom resumes as it cools.
Yellowing from drying out or alkaline soil
Leaves yellow when roots dry out or the soil is too alkaline. Maintain even moisture, use slightly acidic compost and feed regularly.
Root rot in waterlogged soil
Constant wet, poorly drained conditions rot the roots. Use free-draining compost and let the surface dry slightly between waterings.
Aphids on soft growth
Aphids gather on tender shoots and buds, distorting them. Rinse off with water, apply insecticidal soap and encourage natural predators.
