In NE KS, Zone 5, we have barely gotten below 40F. I’ve only brought the tropicals in twice, before they come in for the rest of the season this weekend.
But we are supposed to have 30F, 23F, and 24F lows early next week. I plan to have conifers and deciduous trees sheltered in the block cold frame, since my former SoCal trees haven’t seen any sub-40s to get acclimated yet this year.
How dangerous to a tree are early hard freezes without earlier frosts?
What does a hard freeze do to the leaves for color? I’d assume 23-24F would cause leaf drop pretty quick. I don’t really have any fall color and even the landscape is only just starting to turn. My Cedar Elm is dark green still, the tridents are a lighter green with some faint color on some leaves.
