Q.Is my tree lemon or orange?
Recently, I grew excited about the idea of starting a bonsai tree. I went to my local park and grabbed as many seeds as I could find. The fruits of my labor seemed to be a big flop, but I didn’t let that discourage me. I even decided to try lemons and oranges. Now I have one maple tree sapling, and SIX citrus! The only problem is I have no idea if they were from the lemon seeds or blood orange seeds. Is there any way to tell lemon saplings and orange saplings apart? They’re only 2″ tall at this point.
My guess from you image is little lemon trees, but they are small and young yet.
Give them some time and identifying should be a bit easier.
Here are links with some images.
