Unfortunately, my tomato season is just about over now with all the heat we have here. Hope you like your canned squash since you took my advise!!
That is the best way I know to can it in my opinion. I used pint sized myself since I am the only one who eats it around here unless I can camouflage it in a casserole or bread. . .then my hunny and kids will eat it. If they see it, they will pick it out so what is the point. Your root cellar is looking great in my opinion. . .you are going to be able to store quite a bit of produce in there. Yeah, I am still jealous. . . I can just picture it lined with shelves, barrels, bins and baskets. Stay well Brent and try not to over do it my friend.
