Answer: You didn't mention how long the lime has been in the pot, but transplant shock can cause even a healthy plant to slow its growth, especially if you uprooted it from the garden. I imagine that it will take some time for it to recover from the root loss. While it recovers, be careful not to overwater it, but don't let the soil dry out, either.
New growth is an indicator that the plant has bounced back. When you see new growth, provide fertilizer formulated for for citrus (be sure to follow the label directions).
