Overwintered rootball evergreens
Our local nursery in northern Wisconsin has nice looking balsam firs, 12 to 15 feet tall, that have sat outside, rootballed, for the winter. Are they OK to plant next spring, or is frost damage likely?

Those ball on those B&B evergreens needed to be covered with soil or very deep mulch. If the root ball is just sitting on top of the ground, most likely the roots froze all the way through and the trees are severely damaged, maybe even dead. It will not show up immediately but as the warmer weather progresses. If you decide to buy one or more, make sure you have a guaranteed replacement for a year. They may take a while to die.
