1, family vegetables, flowerpots should be big enough. The container for growing vegetables can be an old flowerpot, an old washbasin, some foam boxes, an empty oil pot and the like, but you can't use a flowerpot that is too small, otherwise nothing can be planted, the soil is too little and the fertility is insufficient. And no matter what container is used to grow vegetables, there should be drainage holes at the bottom, that is, a few small holes should be made, so that it is not easy to accumulate water and rot roots.

2, the balcony to grow vegetables, the soil should be fertile enough. The soil for growing vegetables is best rich in humus, which can be soil, garden soil or ordinary soil that we find outside, but we must add some humus soil, peat or decomposed organic fertilizer to increase nutrients. You can also add some river sand to increase drainage and ventilation, so that the soil in the basin is looser and less hardened, so that the roots of vegetables will grow more smoothly, so that their leaves will flourish, and some vegetables with fruits will blossom and bear more fruits.

3. When fertilizing potted vegetables, we should pay attention to using organic fertilizer and fermented fertilizer as much as possible, because the vegetables and fruits planted with organic fertilizer not only taste better and fuller, but also improve the soil quality. If chemical fertilizer or compound fertilizer is used conveniently, it may have a certain impact on potted soil.

Although fertilizer efficiency is faster, it is not as good as organic fertilizer. The organic fertilizer can be plant ash, chicken manure, sheep manure, cake fertilizer, etc. If you can't find organic fertilizer, rice washing water, vegetable washing water, and some homemade organic fertilizers in daily life, egg shells can also be used to water vegetables and grow vegetables, which will grow vigorously and the leaves will be big and green.
