So my camellia has been happy in the ground for almost a year now (planted her very early spring). She blossomed last year nicely and she had some buds getting ready for winter soon.

Last night there was a very hard freeze (20 something degrees) and this morning I woke up and both her and my espalier bush are wilting. I thought both were winter hardy. I had watered them both nicely last week. Then it snowed maybe an inch and that melted. Then it froze the ground.

Should I put more mulch once the temp goes up to low 40s tomorrow or later today at 35? Should I water tomorrow?

Just not sure why they look sad.

thanks!
