What are the greening methods of closed balcony?

Life balcony needs a beautiful environment, and flower decoration is one of the common methods. There are two ways to decorate, one is potted and the other is planted. Potted plants can be placed directly on the balcony handrail on the premise of setting a safety frame. Fixed planting is to make a fixed planting groove on the balcony floor, with a width of about 25 cm-30 cm and a height of about 20 cm-30 cm. Drainage holes are left in the tank, so flowers and trees can be planted directly in the tank, and potted plants can also be placed in the tank. For concave balcony or corner balcony, because there are walls on both sides or one side of the balcony, a shelf can be erected on the wall, so that flowers can extend to the main space and plants can climb on it, which not only beautifies the balcony, but also plays the role of shading. The other is to use hanging baskets to hang plants on the balcony ceiling or lintel, or to install hanging rails above the balcony to hang various herbs. The service balcony connected with the kitchen and dining room can be used to place fuel, vegetables and sundries. , and play the role of a warehouse. The service balcony is generally decorated by greening outside the wall, that is, the planting trough is hung outside the wall and fixed with steel bars and railings, so that plants can climb and grow in the extension. Closed balconies are generally decorated with potted flowers, and a few potted flowers can be planted on the windowsill to beautify the environment.
