When to Plant Colchicum?

Plant the bulbs from July to September more or less 4 to 6 inches (10 to 15 cm) deep, keeping the bulbs at equal intervals. Colchicum is a type of plant that is perfect for ground cover. It's quite smart to cluster them together. Ten or so specimens in close range will create that many colorful patches.

How do you grow Colchicum bulbs?

Grow colchicum bulbs purchased from the local garden center in late summer in well-drained soil in full to part sun. The sunnier the location for colchicums, the less likely they will flop over when flowering. Amend the soil well with compost. Plant bulbs 4 to 6 inches deep spaced 6 to 12 inches apart.
