Sowing: Yard long beans thrive in heat and humidity, and should be direct sown when the weather stays fairly warm and the soil temperature reaches at least 75 degrees F. Make sure the soil is rich and deeply worked; these beans like full sun. Plant the seeds 1" deep and 3" apart, later thinning to 6-8" apart. The rows should be spaced 3-4' apart. Keep the ground moist until germination, which should occur within 7-10 days.
Growing: This type of bean needs to be trained on a trellis of at least 7' to support its vigorous vining habit; tepee or trellis structures of bamboo or chicken wire often work well. Yard long beans prefer high temperatures, so if cold weather threatens protection may be needed. Since dry weather stunts the growth of the pods, water the plants if the soil completely dries out. Watch out for aphids and mites, which can be a problem.
Harvesting: Yard long beans will be ready to harvest about 60 days after planting. For best taste and tenderness, pick these beans for fresh eating at a length of 15-20". Since the beans grow very quickly, check the vines often. Fully mature beans can be dried and used as soup beans. Fresh beans are best used immediately, but will keep in the refrigerator for several days.
