Pictures will be helpful, but in the meantime...are you certain that the leaves are torn and not eaten? Does this involve a lot of the leaves? I, personally, don't believe that any plant should be purchased with obvious signs of damage, disease, or pests, but a FEW torn leaves should not be a problem for your tree.

I checked for bugs and didn't see any signs of insects. As for disease I don't know. It's not only a few leaves but many of the leaves ahve some kind of tear. This was the only persian lime tree left. There were lots of meyers and orange trees. I saw a key lime one, but didn't like those. I thought it was odd that the leaves were torned, but my friend told me they were o.k. Too late now. the tree does have blossoms. I will try to upload pics tonight.

Can't figure ou how to upload pics..but I brought my tree indoors..
