Biodegradable mulches successfully control weeds in container-grown arborvitae

Traditionally addressed through hand-weeding and/or herbicide application, controlling weeds is one of most costly operations in nursery production. Increased labor costs have made hand-weeding prohibitive as the sole method of weed control, and although herbicides may be effective and less expensive, non-target herbicide loss can be as high as 86% and can harm the environment. To address the economic and environmental impact of weed problems, nursery producers are looking for more sustainable and cost-efficient techniques to control weeds in container-grown plants.
