Averaging 10 to 15 feet tall and 3 to 4 feet wide, Emerald Green arborvitae can become natural privacy fences. Once established, they require only basic care to maintain.

If you are thinking about putting Emerald Green arborvitae in your landscape, here are some tips on how to get them properly in the ground so they live a long and happy life.

  1. Plant Emerald Green arborvitaes approximately 2 to 3 feet apart when planting more than one to create a natural hedge. This spacing allows mature plants to spread out slightly, but prevents roots crowding and competition of nutrients and water. The Emerald Green grows 6 to 9 inches a year once established.
  2. Position the arborvitae in full sun; while it can live in partial shade, the evergreen cannot withstand full shade and will begin to turn brown, eventually dying from lack of sunlight.
  3. Provide well-drained soil, and water the tree thoroughly at planting. The soil can slightly dry out between water applications, but this variety of evergreen is not drought resistant and must receive plenty of moisture during the growing season. Water more frequently and deeply during drought conditions.
  4. Apply a 10-10-10 fertilizer — the number indicated the percentages of nitrogen, phosphorus, and potassium in the product — in early spring to boost the arborvitae’s health for the coming growing season. Fertilize it again in mid-fall after the summer heat is over. Avoid fertilizing when the tree is being planted, as well.
  5. Prune only the sides of the arborvitae if stray branches become too long, or a dead stem needs removed. Pruning the top of the tree is not recommended, as this can ruin its natural, pointed shape. However, it can be done to control the height of the plant. If deer mar the evergreen’s look, pruning can be used to reshape the arborvitae, but do not over-prune.
