Invasive weed problem
I have the invasive weed, American hog potato vine invading 2 of my very old established shade gardens. It is vining all over my plants and spread a cover over all the ground. I also have it in my back yard- far away from these beds, growing along my fence in a swampy wooded area. They have not flowered yet, I read that I need to get rid of it before it flowers and spreads. It looks like there are many many roots to it, almost individual roots. I was thinking of digging out the plants I want to save and store them and then burn the gardens and cover them for a couple weeks to kill off the weed. Will that work? What about the weed in the backyard? will that just spread back to those areas? I cannot burn that backyard area. Any other ideas?
