The Yellow leafs can be Lack of nutrients Giving the plant Nitrogen Fertilizer will bring out dark green color in plants. Give half or less the amount recommended on the package. Tip: You can add nutrients to water by adding air to the water. Place the water in the blender or shake up the water in a clean jug or cup.

Hi again - Thanks for your replies. Here's another picture. Hopefully this one will be a little better for you, Ken. Just let me know if you would like more pics. I took several shots of it. I live in Joplin, MO (the place the EF5 tornado hit a couple years ago, though it missed us by 3/4 mile). The tree was grown in Oregon and I bought it from the Home Depot here (the one that was on the national news and destroyed by the tornado - not that anyone member that or that it even matters as far as this tree is concerned). Anyway, the tree is in very rocky and well-drained soil. I hate to admit it, but I don't know what type of oil I have here (that's because I'm just a beginner and didn't even have any interest in trees or doing yard work of any sort until this summer and I haven't had a chance to get to that yet). We have a lot of native oak trees around if that tells anyone anything. Anyway, my Limber Pine seems to be getting worse by the day. I had given it a good soaking since I hadn't watered it in a week or two, and then we happened to get a lot of rain over several days, so maybe it just got too much water(?). As far as transplant shock, it had looked beautiful and very happy for about 3 months, then all of a sudden it's turning yellow. This seemed to begin after I'd watered it, however it's possible it could have started before that and I just didn't notice it, being that it began on the west side of the tree and I don't often look at it from that side.

This is a good site for basic advise. When in dirt treat like a regular Dracaena, so just dry a bit say top inch in summer. http://houseplants.about.com/od/typesofhouseplants/a/LuckyBamboo.htm

matt I don't know, but leaves usually shrivel and dry up if too dry. I don't use moisture meter (they are not that reliable, unless you have a better quality one); if I have any doubts I just stick a bamboo skewer deep into pot to check for moisture. Just checked my plant, there is 1 leaf that is yellowing - I am quite sure it is just old and is going to dry up and fall off. There are 3 big branches/stems on my plant, mostly 'naked', with leaves just at the top. It is constantly in bloom - I got it in 2012 and it never stopped blooming yet. It really needs to be repotted (still in pot & soil I got it in!), and also pruned, since there is no branching at all, and is getting too tall. Here is photo of 1 yellow leaf, and top of one of the branches:
