Q.Katsura Tree Dying
I built a deck around my katsura tree 13 years ago. Last year I noticed it seems to be dying, lots of dead limbs high up. This year I saw that some branches started budding then went dead. Can something be done?

Covering the tree roots with a deck could have deprived the tree of moisture and sufficient air circulation. The best thing to put around a tree is mulch to the dripline. You can prune out the damaged limbs and take extra care to see the tree gets its cultural needs. I've included a link to tips for its care. You may want to call an arborist who may be able to save it.
