Q.‘Autumn Blaze’ tree info states “One thing to consider is offering the tree protection when chilly winter arrives.”
No further info is mentioned other than the above quote. What protection would it be?

This usually refers to covering a plant or bringing it indoors to protect it from harsh freezing temperatures.
But in your case, in your location, this is probably not needed unless it's a very young and newly planted tree. The USDA plant hardiness zone is listed as 3 through 8. You are in zone 5, so an established tree would not normally need frost protection. But check with your supplier or a local nursery or arborist.
