River Birch are under stress
My 4 year old River Birch leaves are turning yellow and falling off. 60% of the trees are affected either- yellow or dropping.
We went away for 4 days for July 4th and came home today to
see our beauiful 20 ft trees in trouble. It has been steadily in the 90s for several days so I know the heat has affected them. We are watering but hoping tree experts here will reassure us that our trees will come back in time. Any Suggestions beyond watering are much appreciated. Thanx
