Hello! I'm new to this forum and have zero gardening or landscaping experience. I also have killed every houseplant I've ever owned. Nevertheless, I have time now and I'd like to give this a shot...
I have a 12 foot long, extremely ugly retaining wall in my backyard that I want to hide. It sticks up about a 18 inches above the ground. I want to plant low hedges to hide it. From the little research I've done, it seems that dwarf English boxwood is a good option. I would like to know how close to the wall I can plant it so it takes up as little yard space as possible. I also have read conflicting information about how far apart to plant them. I want them to be as close together as possible so they really hide the retaining wall completely.
Thanks in advance!
