How to make the roof garden safe in summer

The roof garden is built on the flat roofs, platforms or parapets of buildings, and its ecological environment is worse than that of the ground gardens. Therefore, it is more difficult to maintain flowers and trees on the roof than in the ground in summer. The author has been engaged in the maintenance work of flowers and trees in roof gardens for many years and summed up some experiences. Now he is introduced as follows.

Early fertilization according to phenology

The roof surface of the roof garden is made of cement and has a good ability to absorb heat. Grasp this characteristic, early in the early spring to the top dressing of flowers and trees, take a thin manure, root fertilization alternating with foliar spray fertilizer. In this way, the roof garden flowers entered the peak season earlier than the landscaping flowers, and the flowering trees and flowers bloomed early and the flowering period was long. In the high temperature season, root fertilization is not carried out. When the flowers and trees lack fertilizer, spraying thin fertilizer or micro-fertilizer in the evening leaves is beneficial to the growth of flower trees.

Shade cooling

The roof garden is bright in summer, with high temperature, high wind speed, and large transpiration of flowers and trees. It is prone to sunburns in summer, and the branches and leaves are burnt or dry. In order to prevent the damage of flowers and trees in summer, measures should be taken in advance to prevent summer. In the first half of April, wind and shade protection will be applied. Shade nets will be directly covered in greenhouses and greenhouses. There will be no greenhouses, greenhouses, fixed windproof wire mesh, and external shading nets (above 70% of the shading rate). When the high temperature comes, depending on the weather watering day and night, the leaves are sprayed with water several times to create higher air humidity and lower heat.

Supplementary pottery

Due to constant watering, a small amount of potted soil loss and volume shrinkage, cracking, lack of planting layer thickness, found that when there are few flower pots, timely addition of potted soil is conducive to flower growth.

Frequent weeding, keeping potted plants and gardens clean, preventing and controlling diseases and pests, timely and at any time observing the growth of flowers and trees, and doing a reasonable job of management.
