I have a four year old 1.7 acre pond. I broadcast planted about a 4 foot perimeter of a good pond side seed mix (I think from Cardno) and then hand planted a nice mix of pickerel, cardinal, bullrush, woolgrass, lizards tail, swamp mallow, etc. It has really turned into a pretty and diverse shoreline. There is a fair amount of competition from grasses...mostly fescue that I feel crowds out some of the broadleaf desirables. Any downside to cleth? Thanks for any warnings or advice.
