Growing guide

Step-by-step instructions for growing Plum

  1. 01

    Plant the tree

    17 Dec to 26 Apr

    Plant a bare-root tree while it is dormant, around 17th December - 26th April. Set it at the same depth it was grown before, stake it firmly, and keep a wide weed-free circle around the trunk. Water it in thoroughly straight after planting.

  2. 02

    Water through establishment

    30 Mar to 27 Nov every 10 days

    Water deeply from 30th March through 27th November, especially in dry spells. Keep up regular watering for the first two summers, because young trees crop poorly if they dry out. Aim for a good soak every 10 days when rain is lacking.

  3. 03

    Thin fruitlets

    14 May to 29 May

    After the natural drop, from 14th May - 29th May, thin congested fruitlets so the remaining plums have room to swell. Leave roughly one fruit every on the branch and remove damaged or badly placed fruit first.

  4. 04

    Harvest the fruit

    28 Jun to 7 Aug

    Pick fruit from 28th June to 7th August when it colours well and comes away with a gentle twist. Harvest over several picks as different fruits ripen, and handle them carefully because ripe plums bruise easily.

  5. 05

    Summer prune

    29 May to 28 Jun

    Prune lightly from 29th May to 28th June in dry weather only. Remove damaged, crossing or overcrowded growth, and avoid winter pruning because stone fruit is prone to silver leaf disease.

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.
