I haven't posted to this forum before. I used to run a full service maint. business, but got into irrigation and lighting more about 10 years ago and gave up my applicator's license too. I have a client with a lot of native oaks and 30 years or more of naturalized vinca major under and around them that she wants gone. Is there any product listed for geting rid of it and/or english ivy? I've used Turflon/ Garlon years ago for brush and poison oak, and I used to use Roundup in a higher concentration for some tougher perennial weeds, but I have no idea what's currently available. Bear in mind I don't want any chance of damaging the oaks. Thanks in advance.
