I have a 12 acre ski lake in NC with 10:1 shallow shoreline for about 20 feet before it drops off. I use to have a lot of shoreline vegetation(which I want) for resisting the boat wakes. My shoreline vegetation (cattails and rushes)has been reduced the past few years due to muskrats and unruly carp. My question is do you pond owners find that spreading fertilizer just above the waters edge will help/speed up the shoreline growth of my cattails and rushes or do you find that it does not seem to make much difference? Just curious before I try it next spring. My soil is mainly silty sand. Thanks.
