I was thinking of adding cattails to my little pond for water quality and to give the fish a place to hide...
I've got a few you can have. <g>
Cattails usually grow in 3' or less water. The only way to keep them from coming back in the majority of your pond is to excavate the sides and slope them up as sharp as possible leaving the only suitable area to grow about 1-3' from the bank. Then they are easily sprayed with an aquatic herbicide. I had a 25' reach track hoe come in and do the work . Took 1.5 days to completely renovate a cow pond and clean the entire bank around a 3/4 acre pond.
You will have some debris to let dry and remove at a later date. If you can with until mid summer when the pond is at its lowest point that helps.
An experienced operator should have no problem working the tracks around the edge of the water.
Just listing what worked for me.
