When is the best time to plant autumn beans?

Green beans are one of our most common vegetables. They have high yield and good heat resistance. They are rich in nutrients and have high nutritional value. They are very popular among consumers. Green beans can be divided into spring beans and autumn beans. So when is the best time to plant autumn beans? Let’s take a look below.

1. When is the best time to plant autumn beans?

The suitable temperature for growing beans is generally between 25 and 28 degrees. In most areas, the best season for planting autumn beans is August and September. However, due to differences in climate in some areas, there may be some differences. However, the latest time should not be later than early October, and the earliest time should not be earlier than mid-July. However, the planting time should be considered comprehensively based on the characteristics of the variety and the local climate.

2. How to grow autumn beans?

1. Variety

Choose high-quality varieties that are highly disease-resistant, adaptable and high yielding. There are many varieties of beans like these on the market, such as "Emerald Green Long Beans" and "Black Melon Beans". They not only taste good, but are also easy to grow and suitable for home gardens.

2. Soil selection

Autumn beans do not have high requirements for soil. Loose, fertile and well-drained soil is most suitable for growing beans. At the same time, it is best if the planting land has not been used to grow leguminous crops in the past two or three years.

3. Seed treatment

In order to save the growth time of beans in the seedling stage, the beans seeds need to be germinated before sowing. The method is very simple. First, brew the bean seeds with warm water at about 50℃ for 15 minutes, then soak them in clean water for about 24 hours. Put the seeds on damp cotton cloth to germinate and they can germinate and be sown in about two days.

4. Reasonable density planting

When sowing, it is necessary to control the spacing between rows and plants to avoid overcrowding which will lead to poor ventilation and light transmission and affect the growth of beans. Generally speaking, the plant spacing should be kept at 30-40 cm and the row spacing should be 60-70 cm.

5. Timely scaffolding

When the bean seedlings grow to about 30 cm, it is necessary to set up a trellis and guide the vines in time. You can choose bamboo poles or branches to build a herringbone or triangular frame and let the bean vines climb along the frame. This will not only increase ventilation and light transmission, but also improve the yield and quality of the beans.

6. Water and fertilizer management

Beans require a lot of water during their growth period, but waterlogging should also be avoided. When encountering drought weather, water should be applied in time; when there is too much rain, drainage should be done well. In terms of fertilization, organic fertilizer is the main one, supplemented by chemical fertilizer. Apply sufficient base fertilizer before sowing, and apply topdressing according to the growth of the plants during the growth period, especially during the flowering and pod-setting period, and apply more phosphorus and potassium fertilizers to promote the enlargement of beans.

7. Pest and disease control

The main diseases and pests of autumn beans include rust and pod borer. When preventing and treating, we should adhere to the principle of prevention first and comprehensive prevention and control. Reduce the occurrence of diseases and pests through measures such as reasonable crop rotation, cleaning farmland, and using biological pesticides . Once pests and diseases are discovered, timely measures should be taken, such as removing diseased leaves and fruits, spraying low-toxic and high-efficiency pesticides, etc., to ensure the healthy growth of beans.

8. Harvest

Generally speaking, beans are harvested when the pods are full and the seeds are not fully ripe. The beans harvested at this time are crispy and tender and have the best flavor. When harvesting, gently pinch off the pods with scissors or your hands to avoid damaging the vines and other pods.
