Growing guide

Step-by-step instructions for growing Rudbeckia

  1. 01

    Plant Out

    21 Feb to 22 Apr

    Plant young plants around 21st February - 22nd April in a sunny, free-draining spot. Set them at the same depth they were in the pot, space them apart, and water in thoroughly straight after planting.

  2. 02

    Water Until Established

    23 Mar to 20 Apr

    Keep the soil evenly moist from 23rd March through 20th April while the roots settle. Water at the base in dry spells, especially in containers, but avoid leaving the compost sodden.

  3. 03

    Deadhead Flowers

    6 Jun to 9 Nov

    Start deadheading from 6th June and keep going until 9th November. Remove faded blooms back to a side shoot or leaf joint to keep the plant flowering for longer.

  4. 04

    Cut Back Stems

    26 Oct to 9 Dec

    After flowering finishes, cut back tired stems from 26th October to 9th December. Leave the crown intact and trim to tidy growth rather than cutting hard into the base.

Why companion planting matters

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
