Horticultural fleece is a thin, nonwoven, polypropylene fabric which is used as a floating mulch to protect both late and early crops and delicate plants from cold weather and frost, as well as insect pests during the normal growing season. It admits light, air, and rain but creates a microclimate around the developing plants, allowing them to grow faster than the unprotected crops.[1]
