About 6 years ago I planted a tangerine seed in my classroom as a project with my students and our tree is now about 5 feet tall. I never assumed it would produce anything, but it makes for a neat houseplant, and I know it will probably not grow true from the parent fruit.

We potted it up about two months ago and it's flowering like crazy right now. Is there anything we can do to increase the odds of it producing something? I have zero expectations out of this, but might as well give it a try, right?
