Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Cat tails in pond

Marlcat, around here, other than nuking with chemicals, the only solution I found has been to drain pond, excavate all the rhizomes and roots systems. I saw trials where excavation missed bits of roots and three years later it was all over the place again.
I noticed also that when water drops in summer, those ponds have cattails growing deeper and deeper in the pond, while stable water level ponds only have a rim of plant that never grows deeper than a foot or two in the pond.

Once they are in the pond, I suggest trimming foliage and removing their fruits regularly, so they spend more energy surviving than taking over the whole pond.

Good luck!
