Thanks, and a little more info.

Brent, I got your response literally just in time: I was about to go spray the tree with 0-10-10 and decided to quickly check email first. Just about every fert I had on hand was high in phosphorus, except one with an analysis of 45-4.5-3. I gave it a little of that, then bought some 12-4-8 today at Lowe's.

Thanks for your feedback. What you said surprised me: phosphorus (I thought) is supposed to promote root growth. If not that, what's it do?

I got hold of the young man who grew those pines in his field. (He actually lives less than 20 miles from me.) He said they were dug in mid-May, so the tree was potted in field soil for about 6 weeks before I repotted it. He also said that he kept one for himself, found the same lack of fine roots, but his also is growing nicely at present.
