Sinclair Pot Topper can be utilized as a pot topper or for mulching beds and borders. It is a superior alternative to bark; in addition to the fact that it prevents weed seeds from sprouting because of its consistency and sterility and its adhesive properties which lock the strands together to guarantee they stay in situ even if inverted. This makes a matted surface layer that is impervious to light sources that weeds require to establish, whilst still allowing the exchange of water to the root zone for plant uptake.
