Which weedkiller would be your choice on a cracked driveway (concrete0
next to a house? Have been asked to recommend on to kill off elder and
dandelions that are growing up through the cracks in the concrete. It's

Standard methods hereabouts a
1. Diluted glyphosate (Roundup).
2. Vinegar (5% acetic acid.)
3, Direct burning (by a portable propane torch.)
