Growing
Mung beans grow in warm weather, but protect them from even a light frost, which will kill the crop. When preparing your garden, aim for a soil pH between 6.0 and 7.5 and make sure the ground is well-drained to prevent waterlogging. Because these plants flower indeterminately, you may find a mix of flowers and pods on a single plant at once. This can make harvesting tricky, so check the pods often. They are ready to pick when approximately 90% of the pods have turned black.
Watch for pests like the bean fly, which can attack the crop as early as one week after germination and potentially cause heavy losses. Whiteflies are also a serious concern; they feed on the plant's sap and can leave behind a sticky honeydew that encourages black sooty mold. Clean and grade your beans before storing them. For long-term storage, keep the beans dry, at a moisture content of around 12%, to prevent spoilage. To freeze your harvest, blanch the beans first.
