15. Do I have to bury the Growboxx® if the surface land is a lawn and I want to plant grass?
If the main purpose is planting plants (either grass, or bedding plants, or other plants) and not the trees, we suggest to plant the Growboxx® in such a way that the surface of the cover is around 3 cm above the surface of the soil. Once the box collapses, the grass is not planted too deep. Over time the plant place will be filled with dust, and eventually the grass will be equal to the surface. You can also fill the holes after a year with some soil, if necessary.
