Most of my trees have been in a greenhouse all winter, but I am keeping an eye on the cedar elm outside. They show no sign of bud swell yet. I do see changes however in the parsley hawthorn and wisteria. If they bud and it freezes again, I can put them in the greenhouse for a short time. In the past, when I collected a tree, or bought something in a cold area and moved in to a much warmer climate, it always seemed to take at least three weeks to come out of dormancy. We have had only one week of nice weather, so I am not concerned yet. Larry
