Your progress sounds fantastic!
Funny how we’re so far apart, but our gardens are in sync. My sweet corn is a tad behind yours, though the field corn all around me is ready to tassel.
I honestly have never heard of taking the blooms off of potatoes! I’ll have to research that. Mine are ready to be dug for some new potatoes - but I’m hoping for a bumper crop for storage well into the winter - now that I’ve figured out how to do it! :)
Really not that far apart, if the map is small enough. LOL Zone 4; but use Zone 3 for most perennials.
My corn is ahead of yours, because I planted Early Sunglow: 65 day maturity; good to 95F, and frost resistant.
I’ve never been able to raid a vine for new potatoes without killing it, no matter how carefully & went in from the side of the hill by hand, so I don’t even try any more: I want storage. The deflowering just came to me, after beheading some onion & garlic scapes, so hit the Net to check it.
