Green Giant Arborvitae has become one of the most highly sought-after privacy screening trees due to its 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. The Thuja Green Giant can provide you with a lush, rich privacy screen in 4-5 years, provided it is well-maintained. It’s drought-tolerant, disease- and insect-resistant, easy to grow, and very adaptable to most soil types. Trees must be watered in the summer months; we can help with a watering system.
