2. Adequate lighting. The key point of teaching you to grow vegetables on the balcony is to provide enough light. Most vegetables need light to grow better. Long-term lack of sunlight may lead to poor growth, so they need to be placed in sunny places. In summer, if the sun is too strong, shade properly to prevent vegetables from getting sunburned.
3. Fertilize in time. Vegetables need enough nutrients in the growth process, which requires us to topdressing from time to time. Generally, thin fertilizer is applied once half a month after planting, so that the nutrients are sufficient and the growth is rapid. The fertilizer can be organic fertilizer, fermented rice washing water or bean dregs.
4. Proper water control. Because the place where vegetables are grown is small, the water is not easy to be discharged, and the watering needs to be controlled. Generally, the soil should be watered and moistened in time after drying. Be careful not to pour too much water, which will accumulate in the basin and cause the vegetables to rot.
5. Suitable temperature. Generally speaking, the suitable temperature for vegetable growth is around 20℃. Too high or too low temperature will lead to poor growth of vegetables. When growing vegetables on the balcony, we should pay attention to controlling the temperature. When the temperature is too high, shade and water in time to cool down. If the temperature is too low, raise the temperature in time to avoid frostbite.
6. Ventilation environment. When planting vegetables, we need to pay attention to providing them with a well-ventilated environment so that they can grow better. Don't plant seeds too closely when sowing, so as not to be too crowded after germination and emergence. Pay attention to placing them in a ventilated place when maintaining, so that they can breathe fresh air well.
