We purchased a new house last September and the landscaping was very overgrown, since it was only an elderly lady living there. I have removed tons of weeds and growth from the flower beds and plants that were to big for the area. (Large evergreens up to the gutters, and junipers covering half of the front windows). I am now working on removal of english ivy that has invaded from the neighbors yard and is in a section of 12' wide by 80' long. What I did was spray with Quick Kill herbicide then after a week, use my brush cutter and cutting the vines about 1' wide then rolling them with pitch fork. That method has worked well and there are a few vines still lingering. I'm up to the point where the ivy grew into what I think is either a Judas or Japanese Maple. I took a screw driver and pruning shears and carefully removed all the ivy from the trees, then pruned the trees hoping the ivy did not choke them out. My question is how far away from the trunks of these trees should I hand remove the ivy before spraying with herbicide? I have been working on the landscaping all winter and was hoping to get all the english ivy removed so I could till and seed before spring. Would the soil be affected by the herbicide enough to not let the seed take root?
