Chilean Blue Crocus problems — and how to fix them
Chilean Blue Crocus (Tecophilaea cyanocrocus) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Corm rot from winter wet
The primary failure point in UK cultivation; outdoor corms exposed to persistent winter rain rot readily. Grow in an alpine house, bulb frame, or a container that can be kept dry from late spring to autumn. A gravel mulch over outdoor plantings helps shed surface water.
Mice and vole damage
The small, palatable corms are a target for mice, particularly in frames and glasshouses. Set traps around growing areas in autumn and winter, or line growing containers with fine wire mesh before planting.
