Topsoil is the nutritious, fairly fine soil which lies on top of the subsoil. Most plants want to have their roots in topsoil in order to grow well, although trees and most bushes will cope with the tougher subsoil. Grass, however, needs topsoil, as do most of the more delicate flowering plants. Topsoil is anywhere between 10-30cm deep, depending how lucky you've been, but it's very common for builders moving onto a new site to strip the topsoil and sell it separately. It's also rather common for them to leave all their rubbish behind - bits of wire, brick, roof tiles and plaster - and cover it with a few shovelfuls of soil. When you kill the present greenery, you will need to have a look at the bumps and peaks and see what's causing them. You may find that you have quite a few barrowloads of rubbish lurking which will leave holes that need filling; you may also find that the soil is extremely poor, so you might want to consider buying topsoil to improve matters.
