Osteospermum 'Voltage Yellow' problems — and how to fix them
Osteospermum 'Voltage Yellow' (Osteospermum ecklonis 'Voltage Yellow') 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.
Blooms closing
Flowers shut in shade and cloudy weather. Grow in the sunniest available spot to keep the daisies open and freely flowering.
Sparse flowering in heat
Bloom can slow in intense summer heat. Keep roots evenly moist and shaded if possible; flowering recovers as it cools.
Root and crown rot
From wet, poorly drained soil. Use free-draining mix, ensure drainage holes, and let the surface dry between waterings.
Aphids
Congregate on buds and young shoots. Rinse off and apply insecticidal soap if populations grow.
