I just ran across this fairly good video on pruning citrus (or as the case may be not pruning), and wanted to share it with everyone https://www.youtube.com/watch?v=hw4ghHbD_1g It is important to remember when it comes to pruning that all of those rules for stone fruits, apples, and pears don't apply to citrus. The end of this video has example of people killing citrus trees by applying traditional fruit and tree pruning techniques to citrus.
