There is a lot of information on citrus on this grower's website. They've been around since I was a kid ( a loooooong time!).

Citrus for me, have always done better in the ground than in containers, but it's been more of a nutrient issue. I've been fertilizing this year like crazy, a dwarf Naval I've got in a container, and it's finally coming back around. Once a year just doesn't seem to do it...
I'm not sure I understand the reasoning w/ the smaller container that Cheryl gave.. but 4 Winds recommends against a pot too large so that you have better control over the moisture. They do need good drainage and don't want to stay wet, which I could see happening with an over large container. What we do in California could be very different from your climate too..
I'd love to get a Kumquat... when I worked in nurseries, we'd pretty much strip the bushes by munching on them whenever we'd walk by.. I do grow a Satsuma mandarin, which I would recommend to anyone that can grow citrus. They ripen in December/January here.... are sweet, peel easily and have virtually no seeds. I'm at the tail end of them now.
