Dwarf Dogwood tree – areas of bark cracking and splitting, how to repair ?
I planted a semi dwarf Dogwood tree , it is in its second year and there are 2 areas ( about 8 to 10 inches ) that are showing cracking and splitting of the outer bark . What is the recommended method(s) for repair? It was suggested that I apply spag moss and a tree wrap product? Your opinion? Much Appreciated Jim Mulcahy / Larchmont , N Y
