Growing guide

What to do through the growing season

  1. 01

    Plant Out

    17 Mar to 1 May

    Plant into prepared soil around 17th March - 1st May, setting the crown at the same level it was growing before. Water in thoroughly straight away, then keep the soil just moist while the roots settle.

  2. 02

    Water Through Establishment

    17 Mar to 30 Jul Dates as each sowing reaches this stage

    From 17th March, water newly planted lupins during dry spells in their first season. Aim for a deep soak rather than frequent light watering, and avoid leaving the soil sodden.

  3. 03

    Deadhead Spent Spikes

    15 Jun to 17 Oct

    Remove faded flower spikes from 15th June to keep the display going and stop the plant putting energy into seed. If you leave some spikes to ripen, collect seed from the most reliable plants only.

  4. 04

    Cut Back Old Stems

    30 Jul to 29 Aug

    After the main flowering flush, cut the flowered stems down to the basal growth from 30th July. Leave the new leafy shoots at the base, because that keeps the plant strong for next year.

  5. 05

    Tidy For Winter

    3 Oct to 16 Nov

    From 3rd October, remove any dead foliage and clear away fallen debris around the crown. Leave the crown intact and do not cut hard into the base, as established plants need that growing point protected.
