Phaseolus coccineus
A tender climbing bean for a warm, sheltered spot in the UK. Sow indoors from mid spring or direct sow once the soil has warmed, then plant out after frost with sturdy supports and keep well watered for a long picking period.
Step-by-step instructions for growing Runner Bean
Sow seeds around 21st March - 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.
Put supports in place from 11th 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.
Harden plants off first, then plant out from 25th April once frost danger has passed and the soil feels warm. Space them apart, set them against the supports, and water in thoroughly straight away.
From 2nd 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.
Start picking from 25th July as soon as pods are long and well filled but still tender. Pick every few days through 12th October to keep the plants cropping, and keep checking closely because old pods slow new flower production.

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.
