Ground ivy (creeping Charlie), violets, oxalis, knotweed are all actively growing here right now, but amines won't kill these hard-to-kill weeds. Also ...there's lots of new tender growth ocurring on flowers, shrubs, vegetables, etc (a concern regarding ester BWC's). So what is safe & effective (right now) for you guys? Amines, esters, or amines w/spreader-stricker??? Keep in mind that we do not beleive there is any good answer. but rscvp, Thanx.
