I may be nuts, but I just spread cattail seeds on about 1/4 of the shoreline of my newly enlarged pond (1A now). My main worry right now is with heavy rain washing the raw dirt into my pond. I spend some time every spring cutting back emerging cattails on about 1/2 the shoreline, and they usually stay back for the rest of the year. The other half of the shoreline is wildlife domain. The cattails provide protection and breeding ground for minnows and other little fish, and the bass know it. They patrol the edges and pounce on their prey.
