I like this chart. I think a lot of people assume if there’s any petal showing - then 32F = death, but reality is far more complicated.
There is a peach in my neighbor’s yard (unsure of variety). I just ordered mine so I have something to look forward to.
Last year, neighbor’s tree was already in “first bloom” stage when we had lows of 28, 20, 18, and 24 on consecutive days, a warmup, then another 20, 23, 21, 23, and 20 a week later. He didn’t get a single peach.
This year, he’s at the Calyx Red stage, maybe ‘first pink’ - it’s on the edge of both. We’ve gone as low as 27, and may get to 23/24 one night in the next week. I feel like he should have at least some crop on his tree, but I don’t know if there is a cumulative effect of multiple freezes or not.
