I bought a few inch plant online 4 minths ago and it grows so fast that already replanted twice, last in a 20 gal container. The tree is pretty, and if it continues growing like this, it may start giving fruit this year.
I plan to keep it in the container and maintain its size for long. Last time I pruned for shape, i put cuttings in for rooting. Too early to say, but the cuttings still look green and nice.
Never tasted the fruit. Just got it for fun and for kids to enjoy the novelty.
