All the leaves have fallen off a new planting. Should I be concerned,
will it recover? I am seeing new buds and there are remaining
buds/start of flowers? where leaves used to be. Not sure if the new
buds are leaves or flowers. Should I continue to water or back off?

Tree is about 3 ft tall if that helps as far as age.

All recommendations appreciated, sorry for the limited description.
