How do I kill woodsy fern roots ?

by Barb M. Stewart
I had ferns growing around and alongside a huge cement porch. The roots grew so massive under weed carpeting, choking out huge azalea bushes to death. I've removed all the weed carpeting, pine chips, all plants (except rows on back and front of very tall arborvitae evergreens. Those roots are a network of plaited fine webbing, like a rat's nest. I'm afraid the fern fonds will choke out the evergreens! PLEASE HELP!

    Cut them off fairly close to the ground. Paint the cut end only with roundup, this helps it to get to the roots quicker. By brushing it on, you will not have any effect on the surrounding plants or your arborvitae.

      I have them in one limited area the fronds get about four feet tall, but haven't had a problem with them being invasive yet, Thinking about moving four of them to another location so you can see the hostas under them, otherwise they are behaving. I hope this helps you. Do the same if you see some pop up in the spring. Keep working at it and eventually you should get rid of them all.
