It is a never-ending battle to keep invasive plants out of our prairies. If left unchecked, they can take over an area and keep out the very native plants we work so hard to grow. As a result, a great deal of effort goes into managing weeds. We try to use the least destructive method possible to remove invasive weeds, including hand pulling, mowing or haying, or if necessary, we can use a chemical treatment by either spot spraying or broadcasting a larger area. We must be very careful with chemical treatments though, because they can harm native plants as well.
