Hey, northern growers!
Here's an in-ground Chicago Hardy, zone 6A, OH. This is its 2nd season of growth since it survived its first winter with very little die-back. I believe it got down to -4F, but didn't stay below 0F for more than a week. It was wrapped up with an agricultural-grade white, winter blanket. It has quite a few shoots with figlets coming in, about the size of a pea. The caliper on this tree was probably no more than 1.0" or 0.875", and it was planted up against an eastern-facing wall (30 ft. tall) that gets excellent morning and afternoon sun. It's probably about 4 or 5 ft tall. Next, I'd like to plant Sal's EL, Ronde de Bordeaux, and Marseilles Black VS in the same general location.
