Growing up, we had a lemon tree in our backyard in California. I loved to be able to go outside and just pick lemons whenever we needed them. As an adult, I must admit that of all the different kinds of citrus trees – lemon are my favorite. Our first home in Phoenix came with two mature citrus trees in the back garden….grapefruit and orange, but sadly no lemon trees. We did plant one, but moved a year later and so did not get to enjoy any lemons.
