I’m slowly convincing my husband to lessen our lawn space and widen a food space. We have two apple trees in the lawn that I want to use as a starting point to learn about layers, chop and drop, food production, and water retention. We have deer, but we can fence (as unobtrusively as possible). Can anyone recommend some plants/ideas? I’m very busy so I don’t want to keep things somewhat basic, but expandable in the future.
