Origins and Cultivation
Adzuki beans come from East Asia, likely from a wild plant called Vigna angularis var. nipponensis. Archaeologists think humans started growing them around 3,000 BC. Now, they're mainly grown in several Asian countries. This includes China, Japan, South Korea, and Taiwan. These countries produce most of the world's adzuki beans.
In Japan, adzuki beans are very important, coming after soybeans. They need warm weather, between 15-30°C (59-86°F), to grow well. You can plant them in many types of soil that drain well and have a pH from 5 to 7.5.
For over 2,000 years, people in Eastern Asia have been growing and eating adzuki beans. The main areas where they're grown are China, Japan, Taiwan, and South Korea. Adzuki beans can stand not having much water and do well in places where it rains a little (20-68 inches a year).
It takes about 10 to 20 days for adzuki bean plants to start growing from their seeds. This speed depends on how warm the soil is. You plant the seeds about half to one and a half inches deep, spaced 2 to 3 inches apart. Keep the rows about 18 to 30 inches apart. You can usually start picking the dried beans 40 to 50 days after the plant blooms.
Adzuki beans can get sick from different diseases and bugs. White mold, Sclerotinia sp., and Pseudomonas adzukicola can harm them. So can viruses spread by aphids, like the curly top virus. Using the right farming methods and keeping the pests away is key to a good adzuki bean harvest.
