Is this River Birch going to survive?

How much water is your tree getting?  River birches need to be well watered.  He suggested 5 gallons of water each week, and to be sure, he said it must be measured.  If an irrigation system is used, it is not enough water.  Is there mulch around the tree?  Is it planted in landscape fabric and rock?  He mentioned that this is a difficult environment for birch trees to grow in.   Rock is quite heavy, and rocks absorb heat.  If there is mulch around the base of the tree, simply move away the rocks/wood mulch from the base and then water as usual.  This will help the tree gets the amount of water it needs.  He said not to be surprised if some of the foliage falls.  Careful watering, and the right amount, will benefit your tree, and it WILL bud out and leaf again.  He also said next spring it may start out kind of slow, but don’t be alarmed.  It will catch up with your other trees and shrubs in no time.  Hope this helps alleviate some concerns.
