Can bare root perennials be planted after a hard frost?

Question

I ordered several perennials and two poplar trees from a nursery and my order was delayed. They just arrived today (10/19/18). The perennials are bare roots, bulbs have leaves three inches high, and the trees are three feet tall and dormant. We have had two heavy frosts here in Wisconsin. What should I do???

Answer 1

If the ground is not frozen and there is still time for the plants to get established, I would go ahead and plant them. The bulb foliage should regrow if a frost nips it. And trees are best planted in fall. But if you are in the throws of winter, you can hold the perennials and trees till spring.

This article explains how to care for the roots until the time is right for planting:
