I was one of the lucky winners of the Not-A-Raffle-Raffle a couple of months ago, and got to pick a beautiful crepe myrtle, provided by Plant Me Green. Since the plant was arriving a little late in the year, it was suggested by them that I overwinter it in an unheated garage, which I plan on doing.
My problem is that I have no idea when I should move it inside. All but maybe 3 or 4 of the leaves have dropped, and it should get to freezing or below pretty soon. Also, do I need to water it over winter?
I have never grown a crepe myrtle before, and I've never had a shrub that needed to be brought in for the winter, so I don't know what to do! Any help would be most appreciated!
