What do you need to prepare for growing vegetables on the roof?
There is also a plastic basin that is not resistant to sunlight and is easy to age! ? The best way to grow vegetables on the balcony is to choose a planting box. The planting box is made of PP material, especially added with antioxidant and ultraviolet absorber, which can prolong the service life of the box and can be used for more than 8 years in outdoor environment.
The chassis of the planting box is watertight, and the water storage area is 2.5 cm, which exceeds the capacity of the water storage area. Water will seep out from the hollow baffle on the side of the planting box, and the mesh is very fine, so the planting substrate cannot seep out, so it will not lead to soil erosion.
The holes in the side plates are also designed for the respiration of plant roots, which is beneficial to the ventilation of soil and the growth of plants. ? Therefore, the planting box is the most suitable in Yeung Yi, and it can't destroy the original structure of the house.

Matters needing attention
First, before planting a vegetable garden, we should understand the load-bearing capacity of the roof and not blindly plant it. Generally speaking, the load of reinforced concrete roof is 150kg/m2, and the weight of loose soil per cubic meter is about 1t- 1t half. That is to say, the roof load is reached when the thickness of soil layer reaches about 15cm. Soil that absorbs a lot of water will increase the bearing capacity of the roof and affect the structure.
Second, prevent the roof from leaking and do a good job in the drainage system.
Waterproofing after planting vegetables on the roof is a problem that cannot be ignored. If you grow vegetables on the roof, you need to make a waterproof layer again. The waterproof layer of old residential areas is generally paved with asphalt, which will age after more than ten years. If you need to grow vegetables, you must add new waterproof materials as waterproof layers. However, new materials are generally used for waterproofing in new residential areas, but a layer of polymer building materials should be added for double protection. Try to use plastic planting pots or ceramic planting pots or other containers instead of foam boxes.
Because there will be a lot of water injected into the vegetable field, the drainage system should be done in advance to prevent water from seeping into the roof. Almost any type of container can be used to grow vegetables, as long as it is strong enough to provide enough space and drainage channels. In addition to traditional professional containers such as flower pots and flower troughs, many utensils in life can be transformed and utilized, such as plastic pots, buckets, flower boxes, wooden cases, aluminum suitcases, food cans and so on. But no matter what container you choose, you must ensure that there is a drain hole at the bottom.
Third, chemical pesticides cannot be used.
Growing vegetables on your roof mainly pursues health and environmental protection, and you can't use chemical pesticides that are harmful to your health. If there are pests, you can use biological insecticidal methods, such as garlic juice and pepper water.
Fourth, there is no soil in the suburbs or on the roadside.
There are pesticide or heavy metal residues in the waste soil in the city and farmland soil in the suburbs, so the vegetables grown with such soil are not safe.
5. There is air pollution near the road.
Planting vegetables on the roof should also consider the pollution in the air. If the building is less than 12 meters and close to the road, it is not suitable for planting vegetables because it is covered by automobile exhaust and road dust. Even in the interior of a residential area or on the roof of a high-rise building, it is best to apply some silicon fertilizer in vegetable fields, so that heavy metals can stay in the planting soil and not be absorbed by plants.
