Yeah, but ever since I've been spraying it with water it seems better.
Great. Be sure to keep it out of too much sun. Also, be sure that when you put trees in pots (other plants too) that you use pots with a hole in the bottom so the water drains out. If the water does not drain out the plant drowns or the water sours. In either case the plant/tree dies. The exceptions to this are water loving plants like willow.
