Crocus spp.
Hardy spring-flowering bulbs for free-draining soil. Plant them in autumn in sun or light shade, then leave the foliage to die back naturally after flowering so the bulbs can store energy for the next year.
Step-by-step instructions for growing Crocus
Plant corms during 6th September - 6th October, pointy end up, at a depth of about in free-draining soil. Space them apart and water in thoroughly straight after planting.
From 28th January to 24th March, keep the plants in a sunny or lightly shaded spot and avoid overwatering. The blooms are good for cutting, but pick sparingly so the display lasts longer.
Remove faded flowers during 2nd February - 3rd April so the corm puts energy into next year’s growth. Leave the foliage untouched for at least six weeks after flowering, and don’t tie it up or cut it back early.
Keep the leaves in place from 28th May until they yellow and collapse naturally. This feeds the corm for next year, so only tidy away the tops once they come away easily.

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
