Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Short growing submerged plants to combat others

Sago pondweed is a good cultivar and while it can get dense it responds readily to herbicides and isn't hard to manage in my experience. Coontail - obviously a different story. I'd be cautious about nuking the pond and leaving a clean slate - you can have dense planktonic algae blooms or FA explode. If you can selectively treat the coontail I'd do so and target the sago only in areas you need clearing [around a feeder, dock, whatever] and leave the rest so you don't have so many free nutrients for the algae to get going. Lots of beneficial macrophytes - some of the forum favorites are american and illinois pondweed, corkscrew eelgrass, and emergents like sedges, rushes, arrowhead and of course hybrid lilies. I would not clear the pond THEN stock GC - you could be inviting some turbidity issues to arise if the pond is devoid of forage for the GC.
