One of the challenges here is to deal with exotics. Grasses are the most serious category. There are three species that are particularly troublesome: cogon grass, Natal grass and Guinea grass. The only practical removal is pulling in the case of Natal grass or digging in the case of cogon or Guinea, especially the later because, as its former scientific name (Panicum maxima) implies, it's a big species. The challenge is finding enough bags to contain it all. It's amazing how quickly the bags fill. On the other hand there are lovely grasses here, my favorite being Lopsided Indian Grass, which shows its stuff in the fall. I had never seen it or known of it before I arrived. It has certainly been a welcome addition to the landscape. I also have some Wiregrass, which is the prescribed firestarter's friend. Most of it hasn't had much to do lately, though. More's the pity.
