Failure to do so makes it almost impossible to keep perennial weeds under control after the shelterbelt has been planted. Mechanical control after planting Mulches Mulches can be made of black plastic, fabric or organic material. Along with controlling weeds, mulches conserve soil moisture and prevent wind and water erosion. Plastic mulches also increase soil temperature, thereby promoting faster tree growth. Before applying any type of mulch, make sure the planting site is weed-free and tilled until the soil is loose.
Plastic mulches are easy to use.
The plastic comes in rolls. The plastic is applied immediately after planting the seedlings. Plastic mulch is susceptible to ripping and puncturing from equipment, wildlife and rough soil surfaces. These tears can easily become bigger if the wind catches them. The thicker plastic is more durable but still susceptible to ripping.
