I purchased this plant in 2014 and slowly graduated it to bigger pots as it grew. Now it is in a 5 gallon container and is producing fruit and more flowers! Once it is established and happy in a specific location, leave it there, water it regularly, and it will do its' thing!
My Citron arrived in good condition this winter, I transplanted it and it began to grow all winter. Suddenly, this Spring it stopped growing and is now all but dead. I will assume i have done something wrong and will reorder to try to give it a better growing period this summer. This is really a great plant.
I bought a 4" pot in mid May and immediately planted it in an 8" pot. It was about 6 inches tall at the time. Now it is over two feet tall and starting to branch out. Because I live in Nebraska, I've moved it indoors and it seems to like the move. Not sure when it will start blooming, but I can't wait. So far, I'm extremely happy.
