How to Grow Crocus
Bulb
Crocuses are small, joyful corms that punctuate late winter and early spring with goblet-shaped flowers in purple, gold, white and striped combinations. They are hardy and easy to grow in pots, borders and lawns, where they can gradually naturalise. Their early flowers are especially valuable to bees emerging on mild days.
Planting
Plant crocus corms from September to November in sun or light shade, choosing soil that drains freely in winter. Set them 7 to 10 cm deep and about 5 to 8 cm apart, with the pointed end upwards where visible. For lawns, plant loose groups rather than rigid rows, lifting small sections of turf if necessary. In pots, use free-draining compost and place corms close together without allowing them to touch.
Care
Water pots lightly if autumn or spring is unusually dry, but avoid waterlogged compost. Once flowers fade, allow the narrow leaves to die back naturally so corms can recharge. Do not mow crocus lawns until foliage has yellowed. Established clumps need little attention, though crowded groups can be lifted and divided after the leaves have died down.
Bloom time
Spring-flowering crocuses usually bloom from February to March, sometimes from January in sheltered southern gardens. In colder northern and Scottish gardens, flowering can be later. Autumn-flowering kinds provide a separate display from September to November, depending on the variety and local conditions.
Garden uses
Tuck crocuses into the front of borders, around deciduous shrubs, through short grass and into shallow bowls or window boxes. Their small flowers look most effective in generous groups. They combine beautifully with snowdrops, miniature daffodils and early cyclamen. Crocus flowers are among the earliest useful resources for bees, so they suit wildlife-conscious gardens.
Tips
Choose varieties suited to your purpose: larger Dutch crocuses make bold lawn drifts, while smaller species crocuses are ideal for pots and rockeries. Protect newly planted corms from disturbance where squirrels are a problem by using a physical barrier. Ensure pots have drainage holes, as winter wet is more damaging than cold.
