Good! Very good! You get a cookie!!
Seriously, make sure that you don't keep the little dish under the pot also....just wanted to mention it.
Keep a good eye on him so that if he gets any spider mites, etc, you can take care of it right away. Look for little webs...put a piece of white paper underneath and tap the branch...if you see little "cayenne pepper" dots then you have mites. The tree is sick and compromised and can fall prey to various predators. But not for long, probably! These elms are tough.
