Well, I grew it from seed over 3 years ago. Since then it has grown to more than 2 feet tall. It has been neglected a few times but it is doing well dispite it's bad treatment. I have heard form some sources that it takes 3-4 yrs for them to fruit and from others that they take 10+ yrs to fruit. So, exactly how long do they take to fruit and will they even fruit if the seed was from a store bought lemon?
