Polyethylene Film for Seedbed Mulch

Obtaining good germination of redcedar seed was a vexing :problem in Oklahoma C-M 4 nurseries before the technique of covering newly sown seedbeds with polyethylene sheets was developed. With polyethylene film for seedbed mulch, germination has been satisfactory. Preliminary trials with film mulching were started in 1946. The results were so favorable that for the past 6 years all cedar seedbeds have been mulched with this material. Polyethylene has become available and relatively inexpensive in the last few years. One common use is as wrapping material for fresh vegetables in a store. Polyethylene is waterproof, it stretches slightly and has some elasticity, and it tears with difficulty but cuts easily.
