Growing guide

What to do through the growing season

  1. 01

    Prepare the Bed

    23 Sept to 21 Oct

    Prepare a permanent bed around 23rd September - 21st October. Take out perennial weeds. Work in plenty of well-rotted manure or garden compost.

  2. 02

    Plant Crowns

    21 Oct to 12 Dec

    Plant dormant crowns around 21st October - 12th December in a sunny or lightly shaded spot. If the ground is still open later, you can still plant. Set the buds just at or slightly above the soil. Do not bury them. Buried crowns rot. Space apart. Water in.

    • Seed, forcing, and spring-potted plants are separate routes.

    Top-dress around the crown from 21st February - 23rd March 2027 with garden compost or a balanced organic fertiliser. Do this once a year. Do not bury the crown.

    Harvest Stems

    24 Mar to 14 Jul 2028 Dates as each sowing reaches this stage

    Do not pick stems in the year you plant. Take a few stems in year two, from 24th March 2028 to 14th July 2028. Pull and twist from the base. Do not cut. Leave plenty of foliage. The leaves are not edible.
