Product Used: Roundup=AE Poison Ivy & Tough Brush Killer Plus Concentrate
I have a hill side approximately 20' x 50' filled with thorn vines approximately 6 to 10 feet tall. I sprayed each vine from top to bottom with Roundup=AE Poison Ivy & Tough Brush Killer Plus Concentrate yesterday and again this morning. This morning I noticed the vines are turning dark brown. (I hope that's a promising sign that they are dying.)
Questions:
-How long will it take for the vines to die completely? I would like to clear the hill side as soon as possible (definitely before it gets to hot).
-Will the thorn vines return this year or next year?
-Can I plant a ground cover in the same area. I am considering low growing drought tolerant --possibly phlox. I am eager to through seeds in the area next month.
ps. This is a long weekend for yard and garden projects, i.e., spraying the vines again or removing the vines from the hill side.
