Diascia barberae 'Piccadilly' (Diascia barberae 'Piccadilly') 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.
Heat-induced flowering pause
Hot summer weather makes Diascia stop blooming and look tired. Shear back by a third, keep it watered and flowering resumes as temperatures cool.
Legginess after first flush
Plants sprawl and bloom less after the main flush. A hard trim of spent stems triggers fresh compact growth and a strong second flowering.
Root rot in wet, cold soil
Cold waterlogged ground over winter rots the crown. Plant in free-draining soil and avoid sitting water, especially during dormancy.
Aphids on new growth
Aphids cluster on soft shoot tips and flower spikes. Dislodge with water, use insecticidal soap and encourage natural predators.
