Control methods:
1) Pellets are a systemic option that is best applied early spring as new growth begins to appear. Well-established perennials will require a heavier dose of 10 per 2,500 sq. . Repeat treatment 3-5 weeks after the first application may be needed to kill the entire root system.
2) Aqua Neat Liquid and Shore-Klear Liquid are a second systemic option best applied mid-season when all the weeds are above the water surface and in full bloom. Again, repeat treatment 3-5 weeks after the first application may be needed to kill the entire root system.
