nostr:npub18994crjwnldrukwym5lz3y2nae84s84v20m2rkngtjnyg549lr6qvxmd6m that's an awesome goal! Good luck to you!
Trees take a while but the payoff is so worth it. I put all my fruit trees in the ground this year. I got about 50 apricots, 30 peaches and 20 nectarines. I'm preparing an area for Moringa. Hopefully still have time to get them established before winter.
If you want tropical, have you considered a green house? Millennial Gardener has videos of his bananas in North Carolina. Stuff can be grown in colder areas but it takes more work.
