Sow these seeds in intervals to have a continuous harvest, which is beneficial because each plant has a relatively short harvest window. Sow them about 2.5 cm below the soil surface. They need full sun and plenty of water. Rows between plants should be around 45-50 cm apart, and plants can be spaced 10 cm apart. Harvest the pods individually as they mature to keep plant productivity high. You can begin harvesting beans when they are about 12-18 cm long; this will usually be around fifty to seventy days. These are excellent for fresh eating and your main harvest (freezing and canning).
