Check that the plants are in a sunny spot and ensure they are being harvested regularly, as leaving mature beans on the vine can slow down production.
To successfully cultivate 'Prizewinner' runner beans, choose a location with full sun exposure. If starting indoors, use 7.5cm pots with free-draining seed compost, planting 4cm deep and keeping them at 18-20C for 7-10 days. For outdoor sowing, wait until the soil has sufficiently warmed in May, planting 5cm deep and 15cm apart. Once established, ensure plants are tied to canes spaced 30cm apart to support their 3-meter height. Regular watering is essential for healthy bean development, and plants should be fully acclimatized to outdoor conditions before being planted in their final location after the risk of frost has completely passed.
