I have had Satsuma Orange, Improved Meyer Lemon, and Miewa (sp) Kumquat in 15 (est) gallon pots for 4 years. In fact, I have new pots standing by for them once the fruits drop. (Should I wait til spring?) We have had mild winters but they have been easy to move under the porch in the threat of a freeze. With the new pots, this will not be possible. So I will opt for covering.
