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.

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.

If it is a balcony with full shading or poor lighting, it is not good to plant this kind of green plants.

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.
