Had thick, at edge, stringy weed growth from sub surface. Took a 2/3 weeks to see results. It did work! Weeds cleared.
But two things 1. Aprx two onths after application. Weed growth has started again.
2. A established willow tree, near pond overflow, showed signs of exposure. Leafs on tree have turned brown. Not sure if it will survive.

This is our fourth season to use Hydrothol 191 to control lake weeds around our dock. We apply it in May and make a second application late June. It has controlled lake weeds 100%. This product has gone up in price dramatically since Covid but we continue its use.

This stuff is amazing, finally figured out what to buy to take care of leafy pond grass I've been trying to get rid of for years. Killed the grass and also the algae.
