We missed the full bloom moment by about 2 months. Dow states "Annual weeds will general continue to germinate from seed throughout the growing season. Repeat treatments will be necessary to control later germinating weeds." We, obviously, missed the opportunity to continue eradication through the growing season and hit the plants near the end of their normal life.
Considering this was our first attempt to get control of these long-term invasive plants, I'm not discouraged by the results. Next year, we should get after these weeds before they completely overrun the lake. The effort will be more productive, easier, and will allow us all to enjoy the lake throughout next summer.
One of the worst aspects of letting the lake degrade is the insect invasion; particularly mosquitoes. In past years, when the lake shore was a hot bed of bugs, we could always paddle out into the lake to escape both the heat and the pests. With the lily coverage, that is no longer true. All of these flying, crawling, slithering irritants have homes on the lake, thanks to the lily infestation. Between the mosquitoes and the weeds, a trip around the lake is less than relaxing.
