Farewell-to-spring problems — and how to fix them
Farewell-to-spring (Clarkia amoena) 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.
Powdery mildew
White powdery coating on leaves is common in warm, humid conditions with poor airflow. Sow at correct spacing, water at the base, and apply a sulphur-based fungicide if severe.
Transplant failure
Clarkia has a sensitive taproot and resents disturbance. Direct sow into final position whenever possible; if starting indoors use biodegradable pots to avoid root disruption.
Short bloom window in heat
Flowering ceases quickly in temperatures above 27°C. In warm climates, sow early in autumn for spring bloom, or make successive sowings in early spring to extend the season.

Most farewell-to-spring issues are care-mismatch, not bad luck. Dial in the basics:
