Q.Will Andromeda Blossoms Survive A Killing Frost?
my plant is still in its container, moved from a sunless 3-season porch to a west-facing balcony. In warm early March weather, it bloomed. Now we’re getting nights in the 20s. Should I bring it inside, or can I cover it with a blanket outside, or will it be fine as is?

Is this Pieris japonica? If so, it is hardy to about -20 degrees F. However, if yours is still in the container I would bring it inside or cover it. It doesn't have the protection it would have if planted in the ground. Plus, if it is still in flower, the blooms will be killed by frost.
