Cluster beans need a container that is at least 12-14 inches deep, and 12-16 inches wide. The container should also have drainage holes to allow excess water to escape. You can use plastic or clay pots, but make sure they are sturdy and won't tip over.
Cluster beans grow best in a loose, well-draining soil mix that is rich in organic matter. You can make your own mix by combining equal parts of garden soil, compost, and perlite or vermiculite. Alternatively, you can use a commercial potting mix.
Add fertilizer after selecting a suitable medium to grow. Cluster beans are heavy feeders and require regular fertilization to grow well. You can use a slow-release fertilizer or add a balanced fertilizer to the soil before planting.
In a sunny area, scatter seeds 12 inch deep and cover with lightly packed dirt. Given that cluster bean have an extended taproot, planting them immediately in the garden is advised. A 5–6 gallon container can also be used to sow cluster beans.
Provide adequate amount of water. Cluster beans need consistent moisture to grow well, but they don't like to sit in waterlogged soil. Water the plants deeply once or twice a week, depending on the weather conditions and the size of your container.
Cluster beans are climbers and will need support as they grow. You can use a trellis, stakes, or a cage to support the plants. Make sure the support is sturdy enough to handle the weight of the mature plants. Green vinyl-coated wire is available for this usage.
Provide adequate sunlight to the plant. Cluster beans need full sun to grow and produce well. Make sure your container is located in a sunny spot where the plants can get at least 6 hours of direct sunlight each day.
Watch for pests and diseases. Cluster beans can be susceptible to pests like aphids and spider mites, as well as diseases like powdery mildew. Keep an eye out for any signs of problems and treat them promptly to prevent them from spreading.
Harvesting for vegetable use begins 40 days after sowing. Cluster beans are ready to harvest when they are about 4-5 inches long and the pods are still tender. Pick them regularly to encourage more growth and prevent the pods from becoming tough.
After the Harvest enjoy your cluster beans. Cluster beans are a delicious and nutritious vegetable that can be cooked in a variety of ways. Try them in stir-fries, curries, or simply sautéed with garlic and butter. Enjoy the fruits of your labor!
