Can the roof of a self-built house in rural areas be used to grow vegetables?

This determines whether the light and temperature environment for vegetable growth is suitable. If the conditions are right, you can basically grow vegetables all year round. It is best to eat vegetables to save space. Choose garlic, onions, peppers, coriander, small vegetables, cucumbers, tomatoes, etc. that are not easy to attract insects. Vegetable ponds can be cut directly with cement, bricks, etc. But this requires waterproofing in advance. Otherwise, it will be bad if water leakage occurs in the future. Containers, plastic basins, basins, porcelain basins, wooden boxes, and foam boxes are all acceptable. From an economic point of view, plastic pots and foam boxes have the lowest cost, but from the perspective of air permeability, they are much worse than tile pots, wooden boxes, etc. No matter which party it is, the drainage problem must be dealt with to prevent the soil caught during drainage from blocking the drainage pipe.

If cost is not considered, of course it is best to buy a professional planting box. Not only is it more beneficial to vegetable planting, but it is also neater and more beautiful to display. This kind of special box also has a filtering soil layer, so you don’t have to worry about drainage problems. Soil cultivation of vegetables requires a soil layer of at least 20 cm thick. If it covers the entire roof, the weight will not be light. If the load-bearing capacity of the roof is insufficient, the danger exists, and as time goes by, the danger increases! So you should also pay attention to this! When growing vegetables, you must know the origin and scope of your roof in advance. In other words, you need to know which places on the roof can be pressed down, how much they can be pressed down, which places cannot be pressed down, and how heavy the entire roof can be. Then, within this range, try to select and plant shallow-root vegetables in an area that is not too large, and the possible roof weight is as small as possible.

I may be a person with different interests. Over the past few years, I've suddenly become obsessed with growing flowers. It seemed like it suddenly exploded. I search for information online every day, buy flower seedlings and flower pots. After growing them for several years, the flowers seem to be too small. It would be better to use flower pots for various dishes. Just think about it and do it, waterproof the roof of your home again, and move all the flower pots and unnecessary cans in the house to the roof. Then I ran to the mountains again, collected a few bags of pine needles, mixed them with rotten rapeseed cake, and started my journey of growing vegetables on the roof.

As a farmer, I also know that my experience in growing vegetables, coupled with my years of accumulation in growing flowers, makes me feel that rooftop planting is easier to master than growing flowers. I was a great success on my first try. This makes me happy. Many people question that it is difficult to grow vegetables on the roof of a rural residence, but I don’t think so. I summed up my experience in eight words: thin fertilizer and diligence. Why do I say this? Or because growing vegetables on the roof is different from growing in the field, the moisture and evaporation are different, so it is difficult to save large amounts of fertilizer.
