Meyer Lemon Tree

I bought a Meyer Lemon Tree about 8 years ago here in Orlando. It was only about 12 inches tall at the time. I came home and planted it and within a year it had grown to about 4 feet tall, and I had a dozen lemons the size of grapefruits. Then the following year it was about 10 feet tall and I had hundreds of lemons half of them the size of grapefruits.
