Growing guide

What to do through the growing season

  1. 01

    Plant Corms

    22 Mar to 19 Apr

    Plant corms during 22nd March - 19th April, deep and apart, in firm, well-drained soil. Water in thoroughly straight after planting.

  2. 02

    Water to Establish

    22 Mar to 31 May Dates as each sowing reaches this stage

    Keep the soil evenly moist through 22nd March - 31st 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. 03

    Deadhead Spent Stems

    17 Jun to 25 Oct

    From 17th June, 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. 04

    Cut Back Old Growth

    1 Nov to 29 Nov

    After hard frost has blackened the leaves, cut the faded foliage to the base during 1st November - 29th November. Leave any green leaves in place until they die back naturally, because they are feeding next year's growth.
