My Arborvitae that I planted 2 years ago are very green on the outside but the center appears brown and dead. Is this normal or are they dying?
Should I feed them, with what?

It is normal for the interior foliage to stop growing as it is shaded out by new growth. Feed you arborvitae Espoma Tree-Tone. Arbs don’t like acidic soil so evergreen food that contain sulfur are NOT appropriate for them. Tree-Tone has no sulfur.
