I have an upcoming job involving removal of extensive English Ivy (EI) and covering the area over with 3-4" of mulch. Here is my plan. Spray the hell out of the whole mess with hot batch of Ranger Pro. Either: Use my landscape rake with Kubota tractor and yank up the EI & apply pre-em and mulch. Or wait til the EI is completley fried and mow it down real short and apply pre-emergent then mulch. Any thoughts??
