Well my order of three blueberry plants arrived today. And even though I went out the the mailbox just after the mailguy usually drops stuff off (been checking it every day for this package), all of the plants were frozen; that is their root balls were rock hard.

It was about 28F when I picked them up, and I don't think the soil could have frozen that hard in just an hour or two outside at 28F. Last night however was down to -2F, and I suspect that the box sat in a truck outdoors last night before being delivered today, and that is when the freezing took place.

Anyway, I placed the box in a cool dark room and after a few hours the roots/soil thawed. The plants seem to be in good shape, and don't look any worse for the freeze. At least no signs of damage at this point.

I am just wondering if it is a waste of time for me to pot these plants up. Can blueberries survive freezing temps to the roots? (If it makes any difference, one of the plants was starting to leaf out, but the leaf buds appear to be fine)
