I have several Mountain Laurel plants which I collected from the wild
around the end of last Winter (they were only about an inch high at the
time). They've been outside in containers all Summer and have grown
nicely, to about a 6 inch height. My question is: do they need dormancy
over the Winter? Sould I keep the outside in a cold frame or bring them
in and subject them to reduced lighting (I have no crawl space or other
cold area that would remain above freezing).
Can I continue indoors with artificial lighting and Summer length days?
