Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Eliminating a weed before it spreads to other pond

Kru:

I know that you said you didn't want to go the chemical route, but I think that will be the best way.

What will you do if after the renovation, it pops back up because of some plants that were missed?

Invasive species are hard to control, but the smaller the area of problem weeds, the easier it is to control.

As for the silt/sediments stirred up while swimming, unless you have a very sandy bottom, or a pea gravel bottom, you will always have that problem.

Again, there are chemicals that can be used to keep the swimming area weed free, and not affect other areas of the pond.

Just like organic farming, going the organic route is a trade-off. You have to trade-off intensive labor efforts to take the place of chemicals, as you are finding out. If the plant will re-grow from any roots that are left, then you can either remove all the soil that is affected, or go with a systemic herbicide. I don't know if you have any other options.

I wouldn't encourage the waterfowl, they bring parasites to the pond in their poop. Do a google search on "swimmers itch".
