If you’re looking for soft, plush, deep-green foliage, a manageable size suitable for small spaces, and a tough tree that can weather the elements, pests, and insects, then the Emerald Green Arborvitae is the tree for you and your yard. The Emerald Green Arborvitae is a handsome tree with a narrow pyramidal shape – a maintenance-free choice for hedges and decorative purposes.
The Emerald Green Arborvitae originates in Denmark, which is why it is also known as Thuja Occidentalis Smaragd, as “Smaragd” is the Danish word for green. The shimmering green leaves that have a feather-like look take on an even brighter, rich hue in the sun.
To plant your Emerald Green Arborvitae, dig a hole twice as wide as your root ball. Place your root ball gently in the hole, ensuring there are no twigs or wires in the hole or around the root ball. Once you’ve placed the root ball in the hole, fill it with soil, and pat it down to ensure the soil is firm. You may surround the tree with a 3-4-inch-deep layer of mulch, making sure to keep the mulch at least six inches away from the tree trunk.
The Emerald Green Arborvitae thrives in well-drained soil of any type, with a neutral to alkaline ph. You should make sure your Emerald Green Arborvitae is planted at least four feet away from your home or any fence to allow air circulation and to allow you to get around the tree. Fortunately, the Emerald Green Arborvitae roots are not invasive and it can be planted near pools, sidewalks, and roads!
The Emerald Green Arborvitae grows in USDA zones 3-8 and can survive in extremely cold conditions, though it doesn’t thrive as well in climates that are hot. The Emerald Green Arborvitae is pest and drought resistant, but a level of care must also be exercised to allow your Emerald Green Arborvitae to be well established. The Emerald Green Arborvitae benefits from full sun, though it will also thrive in partly shaded conditions. A newly planted Emerald Green Arborvitae should be watered generously. It would be best if you watered your Emerald Green Arborvitae every day for its first week, and once a week for the first two months.
Once the Emerald Green Arborvitae is established, you need to water only when the weather is hot and dry. Water should be applied evenly over the root zone, and the ideal quantity is 10 gallons of water for each inch of the trunk’s width. Apply a slow-release 10-10-10 fertilizer during the spring season to give your tree a boost.
The Emerald Green Arborvitae is largely pest and disease resistant. However, poor air circulation may increase the risks of needle and twig blight caused by fungi. The Emerald Green Arborvitae may also be affected by bagworms, spider mites, and stem canker. During the winter, you may want to keep an eye out for deer, as they will eat the leaves.
The Emerald Green Arborvitae is a semi-dwarf cultivar and typically grows to heights of about 10 to 14 feet, though there are trees that will reach 20 feet in height. The Emerald Green Arborvitae has a four feet width, making it a perfect choice when there is a need to manage space. The Emerald Green Arborvitae will grow 1 to 2 feet in its first year but will slow down to about 6 to 12 inches as it ages. The Emerald Green Arborvitae has a narrow column-like shape, that narrows into a pyramid at the top, and will usually grow straight upward without any assistance.
Pruning is best done in the spring to not disrupt the tree’s growth. Avoid cutting branches back to bare wood, as the tree may not produce new growth. When pruning, ensure to clean your prunes before and after pruning to prevent the spread of diseases. The Emerald Green Arborvitae will be better off with selective thinning as opposed to overall shearing. Thinning is cutting selected branches to their point of origin. When pruning, shorten higher branches to allow the sun to reach the lower branches. This method is especially important if you’re growing a hedge.
If you’re growing a privacy hedge, trees should be planted three feet apart from the center. In the instance of specimen planting, trees should be spaced by 5 to 6 feet for the best results.
