Firstly, it depends on whether the planter box is used in the south or the north. If used in the south, the plant's cold tolerance requirement is low, offering a wide range of plant choices, allowing for the cultivation of plants that bloom year-round. In the north, cold-tolerant plants should be selected, and it's essential to insulate the plants during winter, such as by covering them with plastic film. If funds are sufficient, partial or full plant replacements can be made during seasonal changes to maintain the plants' aesthetic appeal.

Choosing Plants for a Balcony: Balcony greening, categorized by green plants, generally falls into three types: ornamental (abbreviated as flower type), harvestable (abbreviated as fruit type), and comprehensive (abbreviated as flower-fruit type): Climbing or trailing plants are commonly planted on balconies, utilizing either parallel vertical or parallel horizontal greening. Generally, western balconies face intense afternoon sun in summer, making parallel vertical greening more suitable. Plants form a green curtain, blocking direct sunlight and providing insulation and cooling, creating a cool and comfortable micro-environment on the balcony. On balconies with better orientations, parallel horizontal greening can be employed.
