  1. Plant Corms

    13 Jan – 15 Mar

    Plant corms around 13th January - 15th March, with the growing point just below the surface in firm, well-drained soil. Space them apart and water in thoroughly straight after planting.

  2. Water to Establish

    15 Mar – 13 May

    Keep the soil evenly moist for the first 15th March - 13th May while the corms root in. Give a deep soak in dry spells, then ease off once new growth is strong and the clump is settled.

  3. Deadhead Spent Stems

    29 Apr – 25 Nov

    From 29th April, remove faded flower stems as they finish to keep the plant tidy and encourage a longer display. Cut each stem back to the base once the last flowers on it have gone over.

  4. Cut Back Old Growth

    11 Nov – 25 Dec

    After hard frost has blackened the leaves, cut the faded foliage to the base during 11th November - 25th December. Leave any green leaves in place until they die back naturally, because they are feeding next year's growth.

Why companion planting matters

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.
