We’ve had a really mild winter so far here in Kansas. It’s been consistently below freezing, but barely. Very little precipitation, but the soil is still holding moisture.
I seem to have a single seedling peach (came up last spring) that hasn’t gone fully dormant yet.
I wouldn’t assume lack of dormancy as a sign of cold tolerance.
Often plants that go dormant are able to handle more extreme conditions while plants that do not (or plants that break dormancy pre-maturely) suffer more damage.
No, but I keep hoping. The last one that didn’t go dormant in winter went dormant in summer instead, during the worst of the heat. It died last summer. I tried to move it and I think I killed it.
