I planted 10 Thuja fast growing Arborvitae trees 2 yr. ago. They are about 3-4 ft tall now. Just the other day I noticed very small light green balls on 4 of them. I don't know if this is normal or could it be diseased ? I live in Raleigh area of NC 27592

  • Fast-growing arbs don't exist. You'll get 12 - maybe in a good year, 18 - inches of new growth per year.
