Weeds Out is a term used to describe the process of removing unwanted plants from an area. This can be done by using FILTERS, sifts, and thins. FILTERS are a type of device that can be used to separate out unwanted particles from a mixture. Sifts are a type of tool that can be used to separate out larger particles from a mixture. Thins are a type of tool that can be used to remove smaller particles from a mixture. All three of these tools can be used to weed out unwanted plants from an area.
