When to plant crocuses?
- Botanical name
- Crocus
- Family
- Iridaceae
Crocuses are planted from September to October. They flower from February to April.
Crocuses are perennial plants.
The crocus flowers at the end of winter, so the dry corm goes in as early as autumn. Species that flower in autumn go into the ground earlier still.
The corm dies in soil where water stands over winter. Cold does a crocus no harm, so the choice of place is settled by drainage.
The corms stay in the ground all year and multiply on their own, so a crocus is propagated by splitting the cluster. It is not raised from seed, because several years pass before a seedling flowers.

Pests and diseases
Listed here is every problem for which the sources name this plant as a host. The problems are not listed in order of how common they are.
- Signs
- Freshly planted bulbs are dug up and scattered over the bed or vanish without a trace. In spring nothing comes up in that spot. Birds rummage through freshly worked soil, rodents carry off the whole bulb.
- Prevention
- Bulbs are most vulnerable in the first few weeks after planting, until they take root. Lay a metal mesh over the bed or over the pot and take it off once the leaves come through. Level the planting spot and leave no husks or leftovers on the surface. Rodents leave daffodils alone, so plant them among the more popular bulbs.
- What to do
- A mesh over the planting spot is the only measure.
- Signs
- White blotches and streaks show over the leaves and flowers. In a heavy attack the petals turn brown and the buds do not open at all. On stored corms and bulbs there are rough grey brown patches.
- Prevention
- The thrips overwinters on stored corms and bulbs. It is most active from July to September. In a warm room it breeds all year, so keep the store cool.
- What to do
- Put up with light damage, see to a clean lifting and encourage the natural predators.
