First, welcome to Gardenweb. The people here a good folks and very helpful. But we need more information. Your profile doesn't where you live or your USDA zone. If you are on the northern Gulf coast and you are in drought conditions that will be a factor. If you are in central or south Florida and the dry season is coming, that will be another factor. How large is the tree, how old? So we need more information before we can answer your question. I can make one suggestion. Call your local county agricultural college extension agent. Google for your state, and in parenthesis "Cooperative extension agent". Every county or parish has a a coop agent, usually at the county seat courthouse. The agent should be able to advise you.

Thanks, I'm in South Ala. Zone 8 - 50 miles north of the Gulf of Mex. The tree is 1.5 years old and about 6 ft. tall.

I would wait till late Feb. if you can. Get as much of the rootball as possible. Cut the foliage back equal to the amount of root mass lost.

bz,
Thanks. I thought that would be about the safest time. Nice to hear confirmation from someone with more experience wih citrus. My neighbor has a big satsuma tree that bears like crazy. He says to add lime every year. Our soil ph is usually very low.
