The Emerald Green Thuja is a very popular plant for hedges and screens, especially in colder climates. It can also make a good foundation plant and is sometimes planted singly as a landscape specimen plant. Occasionally, this plant is pruned to form spiral topiaries. While other members of the T. occidentalis species can be towering specimens as much as 60 feet tall, 'Emerald Green' is a semi-dwarf cultivar that has a narrow pyramid shape. The foliage consists of flat sprays of glossy bright green. The tree has urn-shaped cones about 1/2 inch long that turn reddish brown in fall. Most specimens are 7 to 15 feet in height, occasionally reaching 20 feet. It reaches a maturity size of 12 to 14 feet tall, with a spread of 3 to 4 feet. USDA Hardiness Zones: Zone 3, Zone 4, Zone 5, Zone 6, Zone 7, Zone 8.

Most Plant Me Green trees can be shipped and planted any time of year, unless the variety is specified as only seasonal delivery (such as bare root trees). Our shipping schedule is Monday, Tuesday, and Wednesday. This is to ensure our trees do not stay in a box longer than necessary and arrive to you as healthy as possible. If a package needs to arrive prior to a specific date, or at a more convenient time for you, please notate that upon placement of your order. On some occasions, severe weather and other unusual issues can delay shipping and delivery of your Plant Me Green package. Holiday shipping schedules are set by the carriers.
First, decide on a planting location. Consider carefully what kind of sun, soil, and growing-space your tree or shrub will need. Once you've located the perfect spot, the hole you are digging must be at least double the width and as deep as the root system you are planting. The top of the root system should be level with the ground. Before placing the tree or shrub in the hole, use your hands to gently break up the root system. Once the tree is in place, backfill the hole with native soil and any leftover potting material. Pack down the soil to eliminate any air pockets. When finished, water thoroughly. To insure your plants a successful growth rate and productive life, plant your seedlings per the instructions included in your PlantMeGreen package.
Plant your Thuja in an area with well-drained soil and where it will receive about six hours of direct sunlight each day. Water regularly after planting, making sure to give the tree a deep watering. Try running a slow hose over the roots for an hour or two to accomplish this. While you should fertilize your Green Giant about three times a year, it needs little pruning. Simply remove any dead limbs.
