What plants are planted 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.

Choose plant varieties that are resistant to wind, lodging and waterlogging.

The wind on the roof is generally stronger than that on the ground. Especially in rainy season or typhoon, wind and rain are the most harmful to the survival of plants. In addition, the roof planting layer is thin and the soil water storage performance is poor. Once it rains heavily, it is easy to cause short-term water accumulation. Try to choose some plants that are resistant to wind, lodging and short-term water accumulation.

Try to use native plants.

Native plants have strong adaptability to the local climate. On the roof with relatively harsh environment, choosing native plants can get twice the result with half the effort.
