Because the septic tank is in the southeast of the house, a vegetable garden can be opened there, and the fertilizer is taken from the septic tank, which not only beautifies the septic tank, but also meets the needs of being a small farmer, killing two birds with one stone. Isn't everyone advocating self-planting, self-harvesting and self-selling (planting and eating) now? As long as you have a small vegetable garden, it will not only add a piece of green space to your yard, but also beautify the appearance of the yard and adjust the feng shui. How nice!
