How to Grow Crocus

Timing and depth are essential for ensuring your corms survive the winter and your crocuses bloom come spring.

When to Plant Crocus Corms? 

You should plant your spring-flowering crocuses in autumn, so September or October is ideal. Knowing when to plant crocus UK is important, as it allows them to establish a strong root system before the first hard frosts.

How Deep Do You Plant Crocus Bulbs? 

Plant crocus corms 10cm (4 inches) deep in well-drained soil. Planting slightly deeper can help protect the corms from squirrels and other rodents that may dig them up. Always plant with the pointed end (the "nose") facing upwards.

Crocus naturalising in grass: For a "wild" look, scatter handfuls of corms over your lawn and plant them exactly where they land.
