We haven’t done one yet for the garden, but that’s a darn good idea. I already have some Excel spreadsheet templates for that purpose for our other income streams, which would probably be useful. Let me do a mockup of what our 10-bed garden analysis would be (and we use lasagna gardening methods too so I’ll be able to match up to what you’re working on). I’ll zap that off to you sometime soon, hopefully this week. We can talk more about it if/as needed.
If anyone else has something similar, I’d be game to see what you’ve come up with. Always interested in The Better Mousetrap..
