Bowie’s Crimp-Disc is not like the lightweight crimpers. Crimp-Discs made by Bowie are “Built-Strong...Built to Last” and are used to anchor straw and hay mulch into the soil. The vertical fibers, in rows six inches apart, form a fence that will protect the other mulch fibers from wind. Each vertical standing straw is available to carry moisture into the soil to aid in seed germination. This method is a fraction of the cost of other methods. In high wind areas, this method has proven to be the most effective.
