The horrible weather this year has us farther behind than any other season. So we are still on late summer (weed control apps). Looks like high 20's tonight (1st big frost), soil temps 45, highs in the 50's lows in the 30's for the next week. We have been using T-Zone (ester based 4-way). How late do the weeds grow? How late do you apply weed control effectively? Do you guys have luck with weakening the weed before winter, then it never wakes up in spring?
