Any local garden center will be helpful. I also included a link for books. A local library would be helpful as well. Good luck and hope you get a little site seeing and good eats in while you are here. Brenda Here is a link that might be useful: http://www.statebystategardening.com/bookstore/index.php/cPath/3_10

I've mentioned this before, but my method to handle seedling trees that are too well rooted to pull up is the use the little spray bottle (that fake butter comes in) and spray (more like drip) the cut end with undiluted broad leaf weed killer. Saves having to get in there and dig it out. The seedling can be cut at any length, just getting the stuff on the open cut kills it. I carry the bottle in my garden holster to have it handy as we have a lot of little hackberry, oak and pecan seedlings coming up all the time.

Yes, they can get very large, but that is highly variable. Back when I was in school, forestry prof told us there was one and only one county in the entire USA where black cherry was a commercial timber crop, that being somewhere in PA. I have no idea if that is still the case, but the point is, this species grows across a wide geographic range, but results in terms of tree performance vary greatly. In my "near-north" Wisconsin swampy woods, I've got a few BC's but they'll never amount to anything. I suspect the wetness of the site combined with a possible "frost pocket" regime may be keeping them somewhat stunted and disease-prone. On the other hand, going back to that professor, he would take us to a woods for tree ID work and there was one truly enormous BC that nobody ever got right, it being so very large that at ground level, one could make out no details of leaf or twig, nor did the trunk look anything like what you'd expect of this species at that size and age class-none of the platey arrangements to be seen anymore on this monster. I'll bet that one was pushing 90 or more feet in height. +oM

If you could just take more pictures now it would help. What does the stem look like? Is that leaf at the back pinnate or not? If it is it is not citrus. But it could be the picture misleading me. Did you eat any lychee? Or you could carefully pull away the soil at the base of them stem to see if there's a pit there. No need to dig it up, just scrape back the debris.
