How to grow
Cultivation
Sow seeds in mid April and keep seedlings in a frost-free greenhouse or windowsill unitl the danger of frost has passed. Harden off before planting out in late May in humous rich soil. Provide support with canes for the plant to climb and train it so that it continues to twine. Mulch around the base to retain moisture and water regularly in dry warm weather. Consider planting Nasturtiums alongside as a companion plant to keep aphids away. Pick beans regularly to avoid the plant stopping production. See french-bean cultivation for further advice
