When is the best time to plant kidney beans in the open air?

Open-pit kidney bean planting time

Open-air kidney beans are suitable for growing in a relatively warm and humid environment, so the planting of open-air kidney beans can be carried out in March of spring or August and September of autumn. The temperature at this time is suitable for the germination and later growth of open-air kidney beans.

How to grow kidney beans in the open air

1. Prepare the soil

Before planting kidney beans in the open air, you need to choose suitable soil, such as humus soil or garden soil with rich organic matter content and good drainage. You can also loosen the soil before planting to improve the soil's air permeability.

2. Seeding and planting

Open-air kidney beans can be sown and planted. When planting, you need to choose seeds with full grains, then place them in the sun to dry and sterilize. Take them out after three days and sow them evenly in the prepared soil. Generally, 3-4 seeds can be selected per hole, and seedlings will emerge in a week. If the weather temperature is low, you can also choose to cover them with film.

Key points for planting kidney beans in the open air

1. Open-air kidney beans are fertilizer-loving plants. During the maintenance process, you can provide them with inorganic fertilizers rich in nitrogen, phosphorus and potassium to increase the growth rate of the plants. You can also provide them with decomposed farmyard manure, green manure and other organic fertilizers to maintain their growth and make the plants grow more vigorously.

2. During the growing period, open-air kidney beans are easily harmed by diseases and pests such as anthracnose, rust, root rot, and aphids. Farmers should strengthen field inspections and take timely prevention and control measures once diseases and pests are found to avoid unnecessary losses.
