7 products
Crocus corms are among the first bulbs to flower each year, lighting up Irish lawns, borders and pots in late winter and giving bees an important early source of nectar. Free tracked delivery across Ireland and 24 more EU countries.
When and how to plant crocus bulbs in Ireland
Plant crocus in September and October, 8–10 cm deep and 5–8 cm apart, pointed end up, in sun or part shade. They flower in February and March and are happy in free-draining soil or in grass.

Naturalising crocus in grass
Crocus are one of the best bulbs for naturalising. For a natural look, scatter the corms by the handful across the lawn or under trees and plant them where they land. Over the years they spread into informal drifts.
In a lawn, hold off mowing until the leaves have yellowed, which takes about six weeks after flowering; that is how the corms build up for next year. Avoid spots that stay waterlogged in winter, as wet ground rots bulbs more than cold does. Mice and squirrels like crocus corms, so cover newly planted areas with chicken wire until the shoots appear.
Frequently asked questions
When is it too late to plant crocus bulbs?
September and October is the ideal window. Plant as soon as you can after the bulbs arrive so they have time to root before winter.
How deep should crocus bulbs be planted?
8–10 cm deep and 5–8 cm apart, pointed end up. In lawns, lift a flap of turf, set the corms underneath and firm the turf back down.
Do crocus come back every year?
Yes. In free-draining soil where the leaves are left to die back naturally, crocus return each spring and gradually spread.
