Growing guide

What to do through the growing season

  1. 01

    Plant Crowns Shallowly

    26 Sept to 24 Nov

    Plant bare-root crowns around 26th September - 24th November in fertile, free-draining soil. Set the buds no more than below the surface. Space plants apart. Choose a permanent spot. Do not move them. Deeper planting is why they fail to flower.

  2. 02

    Water In and Establish

    26 Sept to 21 Aug 2027 Dates as each sowing reaches this stage

    Water well after planting, then keep the soil moist through the first growing season, from 26th September to 21st August 2027. Water at the base in dry spells. Do not leave the soil soggy. Established plants do not need routine watering.

  3. 03

    Support Heavy Stems

    5 Mar to 25 Apr 2027

    From 5th March 2027, put hoops or canes in before the stems reach . It is easier than propping up a full plant later. Leave the supports in through flowering.

  4. 04

    Deadhead Spent Blooms

    25 Apr to 18 Jun 2027

    Deadhead fading blooms from 25th April 2027 to 18th June 2027. Cut each spent flower back to a strong leaf. Leave the foliage in place to feed the root.

  5. 05

    Cut Back Herbaceous Growth

    27 Oct to 24 Nov 2027

    Cut the stems down only once the tops have yellowed and died, during 27th October - 24th November 2027. Clear old stems and fallen leaves to reduce peony wilt.
