Some of the most common Evergreen Trees are Thuja Green Giant (Arborvitae), Nellie Stevens Holly, Leyland Cypress and Wichita Blue Juniper. Most evergreen species do well in full sun. Some species of evergreen trees may need protection from Summer Scald (foliage drying out and burning) or winter wind which will also dry out the foliage. This can avoided by watering sufficiently in the summer and watering well in the fall before the ground freezes. Spray solutions called “anti-dessicants” are available to help prevent the drying out of the evergreen foliage.
How to Plant an Evergreen: When selecting a location to plant your Evergreen Trees, the site conditions are the key to long-term tree survival. The major things to consider are soil conditions, exposure to sun and wind, drainage, space constraints and hardiness zones.
Once you have selected the site, begin by digging a hole for the evergreens. The hole should be twice as large as the pot diameter as a guide. Place water inside the hole using a hose. Continue watering until the hole is approximately half-full with water, and then allow the soil to fully absorb the water. Gently tease apart and loosen the pot-bound root ball. Place the evergreens in the center of the hole.
The point where the plant stem enters the soil that came in the pot should be level with the surface of the surrounding ground. Shovel the soil into the hole, gently packing the soil down around the perimeter of the evergreens. Create a ridge of soil around the base of the evergreens.
Use your hands to create a two-inch mound of soil that encircles the base. The circular ridge of soil should be the same diameter as the original hole. This ridge will prevent water from flowing away from the evergreens. Water the newly planted evergreens daily for the first month, unless there is significant rainfall (one inch or more).
