Proper preparation for new bed
My husband and I are putting in a rather large bed in our backyard. What is the proper way to get started? My father said to just rototiller the area and put additional topsoil on that. Advice from someone else was to remove the sod first; rototiller-ing (is that a word?) would lead to me eventually having grass in my bed. My father's response is that I'll loose good soil in sod removal. I'm going to have to bring in a bunch of topsoil anyway though. Thoughts?
