How to grow green beans on a balcony? The latest planting method is here
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 delicious green beans be grown on a balcony? The answer is yes. Next, the editor will introduce to fellow gardeners the growing method for green beans as part of balcony vegetable gardening!
Seedling-raising method for green beans
1. They can be sown directly or raised as seedlings and transplanted. Put 3-4 seeds per hole, cover with about 2 cm of soil, and keep moist. They sprout 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; they can be transplanted once the first pair of true leaves unfolds. Because the root system has weak regeneration ability, water thoroughly after planting.
Daily management of green beans
1. They have strict water requirements; they like moisture but are afraid of drought and waterlogging. Before flowering, water sparingly, generally not watering until the soil is dry; from flowering to the pod-setting stage, they need more water, generally watering once every 2-3 days, and increasing the frequency appropriately when temperatures are high.
2. Fertilization can usually be combined with watering. In the early growth stage, apply 2-3 rounds of decomposed organic fertilizer mainly based on nitrogen fertilizer. From flowering to the pod-setting stage, spray decomposed organic fertilizer once every 1-2 weeks, requiring a nitrogen-phosphorus-potassium compound fertilizer.
3. The suitable growing temperature is 15-25°C. When it is above 13°C or below 15°C, flowers tend to drop. In summer high temperatures, shade and cool them down; in low temperatures, avoid prolonged rain exposure. Bush varieties do not need stakes; for climbing varieties, set up stakes or guide the vines to climb a trellis or railing when the plants are 15-20 cm tall. 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 vine.
Pest and disease control for green beans
1. Bean anthracnose: 70% thiophanate-methyl 800-times solution, sprayed at 7-day intervals.
2. Bean rust: 50% carboxin 800-1000-times solution, sprayed at 7-day intervals.
3. Bean aphid: 10% imidacloprid 2000-times solution.
4. Whitefly: 25% buprofezin 1000-1500-times solution sprayed.
