Yes, Roundup QuikPRO is labeled to control harder perennials such as thistle when mixed at 1.5 oz per gallon of water and applied in a spray-to-wet application to the point of run off. Roundup Quickpro will translocated through the root system to thoroughly kill weeds but will not leach or stay in the soil. It is recommended to wait 2-3 weeks before planting any edibles or ornamentals in the same area where the Roundup QuickPRO was applied.
