I grow Improved Meyer's Lemon in a pot. It is 3 years old. I was told to transplant it from the 5 gallon pot into a 10 gallon pot and keep it there for 5 years if I planned to keep it as a potted plant. If the pot is too large, the tree will concentrate on it's root system instead of growing branches, flowering and fruit. So far, so good. It has enjoyed a sunny spot on the front porch all winter and his flowers on it now.
On that note, I also have a Miewa kumquat tree. It was in a 7 gallon pot when we got it at 4 feet tall. Hubby wanted one before he went into th hospital for 3 months. That was 2 years ago. Needless to say, I didn't have much time to transplant it into a new pot.
After his discharge, we were busy with Physical Therapy, doctor appointments, my work, and chores etc.. It is still in the 7 gallon pot but has been producing like a Champ. I think it's earned it's new home this spring!
