I started growing a grapefruit tree from a seed when I was about eight. Now I am eighteen so my tree is about ten years old. I have always kept it in the house because we live in northern Alberta, Canada and it has reached about eight feet tall. It has never flowered or produced fruit, and I am wondering if there is anyway that I can get it to produce fruit.
Grapefruit trees started from seed take at least ten years to begin fruiting when grown outside in warm areas like Florida. There are many thrreads on this citrus forum talking about containerized grapefruit trees that never seem to flower and fruit. It comes up frequently, look for them. Use the search feature and you can read to your hearts content. When grown constantly indoors the minimum time for the tree to fruit might be double the amount of time when grown in Florida. Some very knowledgeable members of this forum say that a containerized grapefruit grown as a house tree will never fruit. I, my self think it will but I have to admit I have never seen one that has. You should have planted a Key Lime seed, with fruiting time of only about two years, or a Mandarin with a fruiting time of 5 years. - Millet
