I can’t imagine growing in Maine.
My front yard is very large. My son is scheming up a greenhouse with one of his friends who is a builder. We have a fairly short growing season. The key to growing is night temps and our temps run a little cold for early growing. Last frost is May 15.
We have a canning kitchen but we gave away all the canning supplies. It’s something I would like to do.
He’s nomadic. A snowbird farmer. Spends part of the year in Florida at his mom’s house and the other part in Maine. He used to be in horticulture/landscaping so his mom’s hard, even though mostly edibles, looks nice. So depending on your zoning or any HOA rules, you could grow quite a bit in a small yard.
