Long Yard Beans Sow indoors from the end of April onwards at 20-22ºC. After 4 weeks transplant to the greenhouse in a sunny spot with a planting distance of 100x40cm. The plants will need canes to climb and the tendrils can be attached to neighbouring plants. The pods can grow to a length of 60 to 70cm and are suitable for both cooking and stir-fries.
