What are the seedlings suitable for planting on the roof?

Select short shrubs and herbs with strong drought and cold resistance.

Because of the high roof temperature and poor soil water retention, plants with strong drought and cold resistance should be selected. At the same time, considering the special geographical environment and load-bearing requirements of the roof, we should pay attention to choosing more shrubs and herbs.

Choose active, barren-tolerant shallow-rooted plants.

Most of the roofs are under direct sunlight, and the light intensity is high. Plants should try to choose plants that like sunshine. The soil on the roof is very thin. In order to prevent the root system from eroding the roof structure, plants with shallow roots should be selected as far as possible.
