Crocus problems — and how to fix them
Crocus (Crocus vernus) 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.
Squirrels and mice dig up corms
Plant under wire mesh or use deterrents.
Yellow foliage too early
Normal dormancy; do not cut leaves until fully yellow.
No flowers after years
Overcrowded — lift and divide in summer.
Storm-flattened flowers
Site in sheltered spots if windy.
Rot in heavy clay
Plant in gritty soil or raised beds.
