My husband pulled out the overgrown bushes near our house. 15 years ago. I asked him if we could replace the bushes (looking into boxwoods or something prickly) Year after year he keeps saying he will get to it. I decided to do it myself. But I'm a newbie. He tells me you can't plant bushes in the summer. I checked and fall is best, but I'll be at work in the fall. I'm going for if while I can. First I cleared away 15 years of acorn hulls and twigs and leaves. I am planning to buy the bushes. Now he's telling me I need to rototill the area. Is that correct? I'm not going to keep putting this off another year.
