Fantastic idea(s)!! There are endless things you can sell there for gardening (small sculptures, bird baths, etc (if you have room) and fun stuff like wind chimes, etc. In addition to that an outlet for your free range eggs and some other produce will be awesome. There may be other producers in the area that can sell their stuff through your shop on a commission basis?If you had that property with the building, then you could open a storefront. It would be a good place to sell eggs (free range eggs is another business I want to try), homemade soaps, honey, produce, molasses, etc. Then, of course, other things a gardener would need as they buy plants. You could sell mulch, tools, fertilize, compost, and so on.
