Hey All, I am looking for some help on best way to remove large areas of English Ivy. Three areas are about 30 Ft. by 50 feet. I was thinking that I would spray with strongest roundup available then a week later try to remove ivy. For the removal I am not sure whether to rent a tiller or a walk behind Dingo. What do you guys think would be the best way to do the job? Thanks for all of your help!
