I am planning a small border of 2 Holmstrup Eastern Arborvitae (Dwarf Arborvitae that gets only 6 feet tall) and 2 Rose Of Sharons. I want to alternate the Arborvitaes and the Rose Of Sharons and I'd like to plant them
3 (on center) apart. Has anyone tried this plan with alternating Rose Of Sharons and dwarf Arborvitae like Holmstrup? Since they say the Holmstrup Arborvitaes get 2 to 3 feet wide I am thinking that 3 foot centers would work good. I do plan to trim the Rose Of Sharons (in Fall I would think) as I know they can get as big as you let them!Thanks in advance for any opinions or advice.
