My wife and I have lived at our current address for 3 years. Until now we have neglected the backyard, except for a square foot veg garden. But now we have a toddler who loves to play outside so over the past few months we have been designing an overhaul of the backyard! I'm going to use this thread to keep a record of all we do. Until last week we had a few trees and shrubs but no real strategy. That's all changed! We both did some garden design research and worked together to plan our backyard paradise! Here's our plan. It's scratchy but gets the job done. And here are the beds I cut in yesterday! I did use a weed/grass killer on the large open areas just for ease of labor, but I will be cutting out cardboard for the areas around the trees and shrubs. Next stop: Soil Delivery! My question for the community is: How deep should my new top soil beds be? I had planned on 6". Should I do more or less?
