Nemesia 'Sunsatia Cranberry' problems — and how to fix them
Nemesia 'Sunsatia Cranberry' (Nemesia × hybrida 'Sunsatia Cranberry') 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 slows in extreme heat
Although heat-tolerant, very hot dry spells can pause blooming. Keep watered, shear back lightly, and flowering rebounds as conditions ease.
Legginess without trimming
Plants stretch and bloom less if left untrimmed after a flush. Shear spent growth by a third to keep it compact and floriferous.
Yellowing from dryness or alkalinity
Roots drying out or alkaline soil cause yellowing leaves. Maintain even moisture, use slightly acidic compost and feed regularly.
Aphids
Aphids colonise soft new shoots and buds. Wash off with a water jet, treat with insecticidal soap and support beneficial insects.
