My landscaper installed three white (or Jacquemontii) birch trees

summer. They are each about 8 feet tall. I live in NJ and we had a
drought last year where it didn't rain for two months. I diligently
watered the trees almost every day and they seemed to be doing ok.
Our soil is mostly red clay.

My bet is the wrong watering schedule. An inch of water 1 or 2 times a
week would have been better than wetting the top of the ground every
day.
