In areas where weeds are especially dominant, the advantages of cutting the weeds and preventing them from setting seed offset any disadvantages of cutting prairie plants. Spot spraying might still be necessary this year. Both grasses and flowers will be mature, providing beautiful, low-maintenance returns. One cutting per year can be used as a clean-up procedure. In areas where prairie plants were especially tall and dense, much or rake away the dead plant material.
Fire is another method of removing old prairie thatch.
In natural prairie ecosystems, fire not only gets rid of accumulated thatch, it also helps reduce woody plant invasion and stimulates the growth of many native grasses and wildflowers. Rotation between prescribed burns and cutting is ideal for prairies and savannas. Keep in mind that a controlled burn is a useful maintenance tool, but requires some expertise. Be certain to check local regulations and permit procedures and, when burning, always use caution. If you would like to have your prairie burned, but prefer not to do it yourself, give us a call and we will discuss doing the burn for you.
