@RobynBar In that state, you have the option of cutting the foliage back to the crown or leaving it. It won't matter to the plant because there is nothing in the leaves that can be 'recycled' by the plant. Typically, plants reclaim mobile nutrients and other biocompounds from leaves before they are shed, but a hard freeze disallows that from occurring. Hopefully it will start pushing new growth when temperatures are a little more favorable. Good luck, Robyn.
