Acorn Springs didn't impress me, so I encourage you to contact them over and over till they respond. They are great when you want to purchase! I ordered an olive tree, and instantly many leaves got brown tips. Some were yellow and fell off. I tried to reach them by phone and email. No response at all! I didn't even suggest a return. I just wanted to know what to do. On Garden Web someone suggested to repot, fertilize immediately, and so I did that. Took the poor thing to a nursery here in town and she told me what olives like. Whew!! Finally no more new brown tips, many leaves staying green, but no new leaves yet. Good luck!!

It doesn't look like anything TOO serious. Some citrus leaf-miner damage I think, so remove leaves with the little mining trails. Some of the misshapen leaves are just damaged through contact damage which is quite common - unsightly but not detrimental. It looks a little under-nourished. I would give it a good watering, then give it a good fertilizer with some added epsom salts and iron. A regular fertilizing schedule will bring it back to health after a while. Slowly introduce it to some good light, and make sure it stays warm enough with good humidity and it will be fine :)

Now would be a good time to separate them. Key limes have a harder time in lower temperature and both need more sunlight than many other citrus trees. Give preference to the meyer lemon tree over the key lime tree. It is probable that you will get more production out of the meyer lemon. Both trees will need supplemental light though the fall and winter to keep the trees healthy. After separating the plant give the plant a couple of day rest from direct sunlight. Then place the trees in broken sunlight. I just transplanted my poncirus trifoliata to a larger container and placed it in broken sunlight and it appears to be doing well.

Greendreamhome, I am going to make an assumption that because you are living in AZ and in zone 9 like myself that you are going to be planting you tree in ground. With that said, I have both a key lime and a Bearss (Persian) line tree. My key lime tree produces year round, it is very very prolific and I barely give it any attention other than water and fertilizer a couple times per year. My bearss lime tree also produces well but is still young and does not produce as much as my key lime. The limes on the bearss are a little larger but not by much. As for frost sensitivity of the key lime tree, I had temps down to the mid 20's over the Christmas week with absolutely no damage to It and minimal damage to my bearss lime (it had some fresh growth that hadn't hardened over yet that was nipped by the cold temps). So in my opinion either tree is a good choice for a home garden but be prepared to give away half of your key limes because of how many it will eventually produce. Here is a picture of my key lime tree. As you can see below it, I picked as any limes as I could and I still have some falling off sitting on the ground. This is my bearss lime tree. As you can see a much younger tree, but it will be producing much more this season as it is in its second year in ground. Best of luck and let us know what you decide to do! Evan
