Recently I read an article online that said you can start a lemon tree from a seed in the fruit. I found this hard to believe but decided to give it a try. The lemon I used was from the local grocery store. Four seeds were removed from the fruit and placed into potting soil. They were treated like regular seeds that are started in the spring. The seed packets were placed in a tray overtop a heat mat and covered with a humidity dome. I almost fell over when two weeks later there were sprouts in the container. Sure enough, I have three small lemon seedlings growing.
