Let there be light! One word – give them lights. Don’t keep them in the dark. Keep azalea, boxwood, holly, and shimpaku junipers under lights. I think they do better with light as they are not kept cold enough to be completely dormant… I’d put all trees with foliage under lights if I could afford it.
While our Southern friends are still roaming around in their shorts and sandals we have to be concerned about which trees get stored where. I guess that’s the price we pay for not having fire ants, killer bees, or alligators.
