One: Be waterproof. Many people's own houses are very old, and the waterproof effect will become weaker and weaker as time goes by. Especially when placing heavy objects on the roof for a long time and needing a lot of water for irrigation for a long time, it is easy to shorten the time limit for the waterproof layer to play its role. So be sure to check your waterproof before planting vegetables, just in case it is best to do waterproof work again.
Second, ground planting is bigger than potted plants. Because of the limited roof space, many people will choose potted plants, but the best growth state of plants is ground planting. If you want to plant a good plant, you can simulate the ground planting state, such as pouring cement on the roof to form a larger clod area, so that plants can grow well and watering and fertilizing are more convenient.
Third, take protective measures for the roof edge. First, in order to protect people's safety, it takes a long time to bend over to grow vegetables, and accidents are prone to occur under fatigue, so adding protective fences can ensure people's safety. Secondly, for the safety of others, vegetables on the roof are easily blown up in some windy places or occasionally in typhoon and other weather, because the soil layer is shallow, not only the soil will fly, but also plants may fall downstairs and hurt people downstairs.
Fourth, pay attention to distinguish between public roofs and private roofs. This uncle grows vegetables on his roof, which does not affect others. However, if he grows vegetables on the public roof of the community, people on the roof will suffer from the increase of mosquitoes, the stench of fertilization and the leakage of water on the roof. When growing vegetables, he should also pay attention to becoming a high-quality person.
5. Pay attention when choosing vegetable varieties, because the sunshine time on the roof is long, it is best to plant sunny plants, and plants with shallow roots and short plants are also suitable for planting.
