Thank you everyone for the kind words. You're going to love Sweet Diana!
Drew - I think I say that I'm going to stop protecting Sweet Diana for the winter every year and every year I wind up wrapping her.
I haven't done it yet but this year we are experiencing above average temperatures and I'm not that worried. Like I said, the mother
tree is over 2 stories high and has never been protected; she's doing just fine. I did take a large air-layer and plant it in-ground at
the country house which is Zone 5b and she is unprotected. It has been a little warmer than usual there, too, but the ground just
started to get hard and the temps are dipping into the teens regularly now. Averaging in the mid to upper twenties during the day.
I checked on Sweet Diana last weekend and the branches are still flexible and alive. I guess we'll see in the spring.
