Welcome to the Growing Green rangeland and pasture weed control information page. We are the premier provider of noxious weed control spraying services in Colorado. We will develop an IPM (Integragted Pest Management) program to suit the needs of each situation. When treating non native invasive weeds such as thistle, knapweed, toadflax, oxeye daisy, spurge or any unwanted weeds we will identify the weed, formulate an effective plan of action and institute that plan. We have performed weed spraying operations for (but not limited to) the Climax Mine site near Leadville CO, Candela's Co in Arvada and many rangeland pasture settings throughout Colorado.
