Some history first. According to Jim, "I bought your pine many years ago from a grower in central CA. His nursery was a hot spot for trees for a while, but it was picked pretty clean. I styled & restyled it many times, but I don't think it was touched for a year or more." So I have it on Jim's authority that this is a domestic tree, not an import.
I purchased it from Jim in November 2011 and it was shipped from California to Houston in February of 2012. Jim's beautiful handmade pot was destroyed during shipping (Jim was kind enough to send a replacement - equally beautiful). I used the opportunity to change out 1/2 the old soil. The tree grew strongly that spring so I candled in late June and pulled needles in December. Late June is early for candling in Houston - I often wait until late July or early August, but I was conscious of the fact that the tree had not yet adjusted to Houston's climate (heck - I've been here 15 years and I still haven't adjusted). If one candles too late, a black pine will respond by setting buds but will not push any summer growth. Here's an example of summer buds, but no summer shoots on a black pine I candled in late July with my other black pines during its first summer in Houston.

It's not terrible, but a good reminder that it can take trees 2-3 years to acclimatize when moving them to a different part of the country.
