Hessian sacking ideal for wrapping root balls of plants while transplanting. Hessian will help keep the soil conditions moist & help prevent erosion while your plants grow. Hessian sacking can be layed over concrete while curing and wet down with water, to help prevent premature cracking from drying too fast. Hessian should be pinned to the ground using Cosio steel staples or plastic pins. Alternativly rocks can be placed onto the mat to help prevent wind lift. If you are planting through Hessian, carefully cut an X with scissors or a sharp knife. Hessian sacking is not a weed control mat, it may help to suppress weeds but it is not a replacement for weedmat.
