I planted three 12' "duraheat" b&b river birch on 9-10-06. They were planted on uphill side of hole in sloped yard with root collar exposed and soil sloped away from trunk on all sides. I covered with 3-4" of mulch and supplied daily watering. I pulled back mulch the other day and found large quantity of feeder roots growing on top of soil and into the mulch. The 6-10" feeder roots appear to be growing horizontally from root ball and exiting out soil sloping away from trunk. I can't figure out whether this is normal or I've a possible overwatering issue creating an oxygen shortage or something else.Thoughts and comments appreciated!
