No, you shouldn't cover landscape fabric with topsoil. While it may seem like a good idea to add topsoil over the fabric to help improve drainage and provide a better root environment for plants, it can actually have the opposite effect. Landscape fabric is designed to allow water to pass through it, while blocking weeds from growing. Adding topsoil over the fabric can cause water to pool on the surface, leading to waterlogged soil and root rot. Additionally, the fabric can become clogged with soil particles, reducing its effectiveness in blocking weeds.
