Update on lemon trees

It has been exactly 3 months since I plucked my lemon seeds from their nesting place inside some store bought lemons. I have been nuturing them daily since. A few of them have really made me happy, but most of them stopped growing after they were only about an inch tall. They are still alive, just not doing anything. I'm not giving up on them. I think I'm going to re-pot them into some less compacted soil and see if that will help them. This is a photo of my largest lemon tree.

As you can see, it is much larger than the lemon trees around it. I can't explain it.
