Del,
Back in the 'early days' of tree shelters, the manufacturers of the solid tubes used to recommend 'raising' them a few inches, along about the 1st of October, to create a 'chimney' effect, allowing the plants to go ahead and harden off so that they could go into dormancy without having tender tissues damaged by normal fall frosts/freezes. Guess once they went dormant, you could slide the tubes back down & shove 'em lightly into the ground to (hopefully) exclude voles/mice.
The newer, vented types, with 1/2 inch fenestrations at staggered spacings seem to do a better job of allowing the seedlings to 'harden off' without having to raise or open the shelters - and, at least in my hot zone 6, prevent young trees from baking during July & August.
