Lemon Tree Died

Ok, it's official, the lemon tree has died. I left it out this winter in hopes that it might survive and be a super hardy lemon tree. It didn't happen but I don't feel too bad about it. I was out and about today and saw a citrus tree that had to be fifteen years old or more. The trunk was thick and had many branches. It was dead. The frost probably hit it pretty hard this last winter as it did a lot of trees in the area. Good news... The kaffir lime tree lives! Of course I kept it inside and under a grow light with plenty of water and babying but I really really like it.
