Growing guide

What to do through the growing season

  1. 01

    Sow Seeds Indoors

    18 Apr to 2 May

    Sow seeds around 18th April - 2nd May in deep pots or root trainers, about deep. Keep them in a warm spot and water just enough to keep the compost evenly moist, not wet.

  2. 02

    Set Up Supports

    25 Apr to 16 May

    Put supports in place from 25th April before you plant out. Use strong canes, netting or a wigwam, because runner beans climb fast and get awkward to fit around a finished support.

  3. 03

    Plant Out Seedlings

    9 May to 6 Jun

    Harden plants off first, then plant out from 9th May once frost danger has passed and the soil feels warm. Space them apart, set them against the supports, and water in thoroughly straight away.

  4. 04

    Water and Feed

    9 May to 25 Oct Dates as each sowing reaches this stage Optional · repeat every 2 weeks

    From 9th May, water well whenever the top of the soil starts to dry out, especially once flowers open and pods begin to form. A mulch helps hold moisture and keeps the crop steadier in a dry spell. Once pods start to form, feed every couple of weeks with a high-potash liquid feed to keep the plants cropping.

  5. 05

    Pick Pods

    1 Aug to 25 Oct Dates as each sowing reaches this stage Optional · repeat every 3 days

    Start picking from 1st August as soon as pods are long and well filled but still tender. Pick every few days through 25th October to keep the plants cropping, and keep checking closely because old pods slow new flower production.
