The leaves of lace leaf maple, in a container, are drying out and the trunk and limbs are discoloring. I cannot see any signs of insects. I live in Seattle. Can I do anything for it?

I would check the roots. You may have root rot, which would affect the visible part of the tree. It may also be a fungus. Treat the tree with a fungicide as well. And last of all, make sure it is getting enough water. A tree in a container outside in summer should be watered daily.
