Persistent herbicides sometimes make their way into the regional composting system. Unsuspecting gardeners then purchase herbicide contaminated compost and soil mix leading to plant damage. Learn how to recognize the damage, what to do about it, and how to avoid the problem. Also learn how to use compost in your vegetable garden, landscape, and lawn. Avoid problems from over applying compost.
