Diascia 'Wink Coral Pink' problems — and how to fix them
Diascia 'Wink Coral Pink' (Diascia × hybrida 'Wink Coral Pink') 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 stalls in heat
High summer temperatures pause blooming and the plant fades. Trim back, keep moist, and flowering rebounds as the weather cools.
Sprawling, fewer flowers mid-season
Growth loosens and bloom thins after the first flush. Shear spent stems by a third to drive compact regrowth and a fresh wave of flowers.
Crown rot in cold wet ground
Waterlogged winter soil rots the crown of overwintering plants. Use free-draining soil and avoid standing water during dormancy.
Aphids
Aphids feed on soft new shoots and flower spikes, distorting growth. Wash off with water, apply insecticidal soap and support beneficial insects.
