Growing guide

Step-by-step instructions for growing Blueberry

  1. 01

    Plant Blueberries

    6 Dec to 15 Apr

    Plant container-grown blueberries at 6th December - 15th April in a large pot filled with ericaceous compost. Set the crown at the same level as the compost surface and water in thoroughly straight away.

  2. 02

    Water to Establish

    9 Feb to 8 Aug

    Keep the compost evenly moist from 9th February through 8th August, especially in dry spells. Use rainwater if possible, because tap water can raise the compost pH over time.

  3. 03

    Mulch and Feed

    15 Feb to 17 Mar every 365 days

    Top-dress with ericaceous compost or pine bark mulch from 15th February to 17th March. Repeat every 365 days to keep the root zone moist and support fruiting.

  4. 04

    Protect Ripening Fruit

    16 May to 31 May

    Put bird netting over the plants from 16th May before the berries start to colour. Fix it securely, because birds will strip ripe fruit very quickly.

  5. 05

    Harvest Berries

    25 Jul to 14 Aug

    Pick from 25th July to 14th August once the berries are fully blue and come away with a light pull. Harvest over several weeks as the fruit ripens unevenly, and handle the crop gently to avoid bruising.

  6. 06

    Light Prune

    16 Jan to 15 Feb

    From 16th January to 15th February, remove weak, dead or crossing stems and shorten a few older shoots if the bush is crowded. Blueberries need only light pruning, so avoid hard cutting back.

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.
