How to grow green beans on a balcony: easy to grow well at home
Green beans are one of the common vegetables on the dining table. Whether stir-fried on their own, stewed with meat, or blanched and served as a cold dish, they suit people's tastes very well. Can such a delicious vegetable be grown on a balcony? The answer is yes. Next, the editor will introduce to fellow vegetable growers the method for growing green beans as part of balcony vegetable gardening!
Seedling raising methods for green beans
1. They can be sown directly or raised as seedlings and then transplanted. Put 3 to 4 seeds per hole, cover with about 2 cm of soil, and keep moist. Seedlings emerge in about 1 week. If the weather is too dry, cover with film to retain moisture.
2. If transplanting, do it as early as possible; transplant once the first pair of true leaves has unfolded. Because the root system has a weak ability to regenerate, water thoroughly after planting.
Routine care for green beans
1. They have strict water requirements and like moisture but fear drought and are adverse to waterlogging. Before flowering, water sparingly, generally watering only when the soil is dry. From flowering to the pod-setting stage, more water is needed, generally watering once every 2 to 3 days, and increasing watering frequency appropriately when temperatures are high.
2. Fertilization can usually be combined with watering. In the early growth stage, apply 2 to 3 rounds of decomposed organic fertilizer mainly based on nitrogen fertilizer. From flowering to the pod-setting stage, spray decomposed organic fertilizer once every 1 to 2 weeks, requiring a compound fertilizer of nitrogen, phosphorus and potassium.
3. The suitable growing temperature is 1 5 to 2 5°C. When it is above 13°C or below 15°C, flowers tend to drop. In high summer temperatures, shade and cooling are needed, and during low temperatures, avoid prolonged rain exposure. Bush varieties do not need supports; for climbing varieties, when the plants are 1 5 to 20 cm tall, set up supports or guide the vines to climb a trellis or railing. About 10 days after the flowers fade, the pods can be harvested when they are about 10 cm long. When harvesting, hold the flower stalk with one hand and pinch off the pod with the other, taking care not to pull hard and break the stem or vine.
Pest and disease control for green beans
1. Bean anthracnose: 70% thiophanate-methyl 800-fold solution, spray at 7-day intervals.
2. Bean rust: 50% carboxin 800-1000-fold solution, spray at 7-day intervals.
3. Bean aphid: 10% imidacloprid 2000-fold solution.
4. Whitefly: 25% buprofezin 1000-1500-fold solution, spray.
