You don't need to do anything but let it grow Ken. As long as it gets plenty of sunlight and is kept above freezing, it will produce.
It will likely drop most of its flowers and young fruit, but almost every group of flowers will surely hold on to from 1-3 fruits. You will have something...
Congratulations on your tree.
I need to go out and finish picking mine now that you remind me. We have so many Citrus trees around here in DeLand its easy to take them for granted...
