River birch - no leaves on some branches

Our River Birch has several branches that did not leaf out this year. The branches are sporadically spaced throughout the tree so not just the top or bottom. Ttree are two other trees within 30 yards. The first is about 20 yards away and is a Mulberrt tree; the second is 30 yards away and is a silver maple which is extremely large. I'm curious if we didn't water the tree enough last year. We started watering about once a week in July and August. We are located in the north western part of Cass County Missouri. Thank you in advance. - Laura -
