Description: This study compares the use of plastic films to conventional methods for establishing hardwoods on a recently cultivated old field site using 1-year-old micropropagated plantlets of white ash (Fraxinus americana L.) and silver maple (Acer saccharinum L.). After one growing season in the field, height of plantlets with all weed control treatments exceeded the height of the plantlets in the non-weeded control. After two growing seasons, plantlets of both species established with plastic films were taller than plantlets with conventional methods of weed control or in the non-weeded plots. No differences were found in plantlet height growth when established with opaque white film, solid black plastic, or porous black plastic. Silver maple plantlets were taller than the white ash plantlets after the first (47 vs 35 cm), second year (114 vs 72 cm), and third years (179 vs 101 cm). Soils under the plastic films had more available moisture in the spring and less available moisture during the summer than the other treatments. During the late fall, soil moisture was again near field capacity in all treatments. After three growing seasons, the solid plastic films had begun to disintegrate. Our results suggest that plastic films can be an effective alternative to chemical or mechanical weed control when establishing hardwoods.
