A Detailed Guide to Growing Black Bean Sprouts at Home
Nowadays there are more and more varieties of sprouts, no longer limited to mung beans and soybeans, and the nutritious black bean sprouts have won the favor of many people. Black bean sprouts are high in protein and have a very crisp, tender taste, and you can grow them at home too. Below is a detailed explanation of the method for growing black bean sprouts at home.
1. Choosing suitable black bean seeds
The quality of black bean sprouts is largely and directly related to the quality of the black bean seeds used for sprouting. It is recommended to choose freshly harvested, fully mature black bean seeds from the current year. The specific requirements are:
1. The black bean seeds should be round, plump and full;
2. The color of the black bean seeds should be relatively bright and full of luster;
3. The black beans themselves should not have suffered mechanical damage, such as being flattened or crushed;
4. The black bean seeds must be guaranteed to be free of pests and diseases.
2. Treating the black bean seeds
Before sprouting black beans, it is essential to soak the seeds, as this promotes germination and lays a good innate foundation for the black bean sprouts to grow vigorously afterward.
Method for soaking black bean seeds:
1. Put the selected black bean seeds into warm water at about 60°C and soak for about 3 minutes, then immediately rinse them with cold water 1-3 times.
2. Place the rinsed seeds in warm water at about 20°C and soak for about 10 hours, then dry them and you can begin sprouting.
3. Sprouting the black beans
Prepare a suitable sprouting container. If you are a beginner, it is recommended to buy a container specially designed for sprouting, as the success rate will be higher.
Then put the soaked black beans into the sprouting container and place it in a shaded spot at 21-28°C. If the temperature is above or below this range, you can regulate the temperature by watering: if the temperature is low, water with warm water; if the temperature is high, water with cold water. For growing black bean sprouts at home, this is a relatively simple operation.
4. Managing germination and sprouting
In the daily management of germination and sprouting of black bean sprouts, the most important thing is watering, and there is an art to watering too. According to experienced growers, there are 2 methods for watering black bean sprouts:
1. Sprinkling
Sprinkle a relatively large amount of warm water over the entire sprouting container, making sure all the black bean sprouts are thoroughly watered. You can stop sprinkling once the temperature of the water flowing out of the container matches the temperature of the warm water poured in.
2. Flooding
The second method is to directly fill the entire black bean sprouting container with warm water, with the water depth preferably 2 cm above the black bean sprouts. Soak the sprouts for 3 minutes, then drain the water, and repeat the operation 1-2 times.
5. Harvesting the black bean sprouts
Black bean sprouts should not be harvested too early or too late. The best time to harvest is when the embryonic stems of the black bean sprouts have grown to about 5 cm, the roots are about 1 cm long, and the true leaves are just beginning to emerge; then you can harvest this crop of crisp, tender and tasty black bean sprouts.
In general, black bean sprouts are easy to grow and the yield is fairly decent. The output ratio of black bean seeds to black bean sprouts is usually about 1:6, meaning 1 kilogram of black bean seeds can grow about 6 kilograms of black bean sprouts.
