Troubleshooting
Radicchio 'Rossa di Verona' problems — and how to fix them
Radicchio 'Rossa di Verona' (Cichorium intybus var. foliosum 'Rossa di Verona') 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.
Failure to heart up
Plants sometimes stay open and leafy instead of forming a tight ball, usually from sowing too early, warm weather or loose soil. Sow in summer for autumn hearting and grow on firm, fertile ground.
Bolting
Heat and dry soil push plants to flower prematurely. Maintain even moisture and choose the correct summer sowing window for your climate.
Rot in the heart
Tightly packed heads trap moisture and develop Botrytis or bacterial soft rot in wet weather. Space generously, water at the base, and harvest before extended rain.
Pale or green heads
Without a cool spell and light frost the red pigment fails to develop fully. Time the crop so heads mature as temperatures fall.
