Green Giant Arborvitaes have become one of the most highly sought-after privacy screening trees due to their rapid rate of growth and high resistance to deer browsing. Growing at rates of 2-4 Ft per year, Green Giants are a great choice for either privacy screens or wind-breaks. Green Giant Arborvitae are extremely cold-hardy and perform very well throughout the Northeast, especially Long Island. They are uniform growers and do well in hedge-form or individually planted. They prefer full-sun but can handle part-sun conditions as well. Green Giants need regular watering and fertilization. If provided with both, you will have a deer-proof, cold-hardy green wall in no time!
