Prowl H2O has done a good job for me on seedling Johnsongrass in the garden, but won't touch rhizome Johnsongrass or nutsedge. After 3 months or so, it wears off enough that pigweed starts making a comeback, but by then, the watermelons, winter squash, and sweet potatoes have pretty much run out and covered bare ground, so it's just a plant here and there.
