What plants are suitable for planting on the roof? How to prevent the roof from being damaged and flooded by planting?

The natural environment of the roof is very different from the ground and indoor. High-rise buildings are windy, hot in summer and cold in winter, and sunny, which is easy to cause drought. Therefore, planting flowers on the roof is exquisite and selective. Common ones are Gardenia, Bamao, Bauhinia, Lagerstroemia indica, Begonia, Chimonanthus praecox, Tianzhu, Rhododendron, Peony, Camellia, Michelia, Rose, Kumquat, Jasmine, Canna, Lily, Celosia cristata, Grape, Wisteria, Ivy, Parthenocissus tricuspidata, Osmanthus fragrans, Chrysanthemum, Yingchun and Lotus.

1, select positive and barren-tolerant shallow-rooted plants.

Most of the roof garden is in direct sunlight, and the light intensity is high, so the plants should be as positive as possible. In some specific small environments, such as under the flower stand or near the wall, the sunshine time is short, so some semi-positive plant species can be selected appropriately to enrich the plant species in the roof garden. The planting layer 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.

Because fertilization will affect the sanitation of the surrounding environment, the roof garden should try to plant barren-tolerant plant species.

2. Choose shrubs and herbs with strong drought and cold resistance.

The roof garden is hot and windy in summer, and the soil layer has poor water retention and poor thermal insulation in winter. Therefore, plants with strong drought and cold resistance should be selected. Moreover, considering the special geographical environment and load-bearing requirements of the roof, we should pay more attention to the selection of shrubs and herbs to facilitate the transportation and planting management of plants.

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

Generally speaking, the wind on the roof is 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. So try to choose some plants that are resistant to wind, lodging and short-term water accumulation.

4. Choose evergreen plants that can overwinter in the open air in winter.

The plants in the roof garden should be evergreen as far as possible, and the varieties with beautiful leaf shape and plant shape should be selected. In order to make the roof garden more colorful and reflect the seasonal changes of the garden, some colorful tree species can be planted appropriately; In addition, if conditions permit, some potted seasonal flowers can be arranged to make the garden have flowers in all seasons.
