First, the closed balcony can't use large flowerpots to plant flowers on the closed balcony, because the air circulation standard is poor, so flowers and plants should not be maintained with large flowerpots as far as possible, because there are more and more soil layers in large flowerpots, which are not easy to dry quickly after irrigation, and the underground stems can't breathe quickly. If bonsai soil often accumulates water, it is prone to root rot. So in a closed balcony, flowers are usually planted in smaller pots. After that irrigation, unnecessary water will seep out and evaporate more quickly. Because the flowerpot is small and the soil layer is small, even if the closed air circulation is poor, it is not very piled up, which will hurt the roots.

Second, the soil stratification should use nutrient soil to plant flowers on the closed balcony. The soil stratification should be loose, breathable and not caked, which is also the norm for indoor flower cultivation. The air circulation is not good, and the soil can be eliminated quickly after layered irrigation. Try to configure some fine-grained soil, which is convenient and quick to breathe and absorb water. You must not use pastoral soil for maintenance. Don't buy garden flowers, such as common garden flowers, rich trees and osmanthus trees in spring.

Try not to buy this kind of flowers. If so, try to buy plants planted in nutrient soil. The loose and breathable soil layer is suitable for indoor flower cultivation. After irrigation, unnecessary water seeps out, and it is not easy to accumulate and rot roots, and it is not easy to have problems in flower cultivation. When planting flowers indoors, semi-fine granular soil, such as coal ash, inorganic matter and river sand, should be added to improve the air permeability of the soil. After irrigation,

Third, the closed balcony can't grow flowers without sunshine, and the flowers at home can't grow flowers without sunshine. Even if flowers don't like sunlight, they should see some scattered light moderately. For example, the usual wealth trees, money trees and tiger orchids should be placed one or two meters away from the balcony, and the scattered light can only be increased very well.

Some flowers especially like sunshine, such as succulents, and some ornamental plants, which must be placed in Nanyang Terrace to get more sunshine. If it is a balcony with full shading or poor lighting, it is not good to plant this kind of green plants. If there are many succulents, we should add some plant growth lights in the case of insufficient sunshine. Only in this way can a good stick be cultivated, especially in a closed balcony, where sunshine is very important. If you want to plant flowers on a closed balcony, you must keep them flourishing.
