Growing guide

What to do through the growing season

  1. 01

    Plant Crowns Shallowly

    25 Aug to 23 Oct

    Plant bare-root crowns around 25th August - 23rd October 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

    25 Aug to 20 Jul 2027 Dates as each sowing reaches this stage

    Water well after planting, then keep the soil moist through the first growing season, from 25th August to 20th July 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

    9 Apr to 30 May 2027

    From 9th April 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

    30 May to 23 Jul 2027

    Deadhead fading blooms from 30th May 2027 to 23rd July 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

    25 Sept to 23 Oct 2027

    Cut the stems down only once the tops have yellowed and died, during 25th September - 23rd October 2027. Clear old stems and fallen leaves to reduce peony wilt.
