Vibrant green year-round foliage and a neat, slightly pyramidal upright form make 'Smaragd' a great choice for many situations. Thuja occidentalis 'Smaragd' can be planted as a single specimen for a stand alone feature or in small quantities to punctuate a border and create structure. It can also be used for hedging, although it takes a few years to knit together into a consistent screen.
Known as a White Cedar or Arborvitae, Thuja 'Smaragd' can be expected to reach a height of 4+ metres and spread of 2 metres in 20 years. Any moist, well-drained soil in full or part sun will suit. This conifer has received the RHS Award of Garden Merit.
AKA Smaragd arborvitae, White Cedar Smaragd, Thuya Smaragd
When planting Smaragd Arborvitae conifers, it is important to prepare the planting area well. Pot grown conifer trees can be planted at any time of the year.
Firstly, remove all weeds and grass within a metre of your desired planting hole then dig a hole as deep as your root mass and approximately 2x as wide. We recommend digging a square hole as this encourages the roots to grow straight as opposed to around inside the hole. To help your tree establish more effectively, we advise applying root grow (sprinkle in the hole for pot grown trees), especially if you have poor soil. Gently loosen the roots and place into the planting hole.
If your soil is poor, mix 50% of the original soil with 50% high quality compost, fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree as this can cause problems.
We advise planting young trees with a stake and tie kit. To see how to use a tree stake and tie, watch our informational how to videos.
If you’re planting in dry weather, water well and regularly for the first few months. The same goes for spring and summer planting. Make sure to keep an eye on your young tree and increase watering if there are extended periods of hot or dry weather. If you’re planting in autumn, you may only need to water your tree a little. We also stock a range of irrigation kits, suitable for a variety of planting schemes.
Once planted, it is important to keep the area free of competing weeds and grass for the first couple of growing seasons. Using a glyphosate based weed killer or installing mulch matting and bark chips will aid in this. Do not simply mow the grass around the area as this will only encourage it to grow more vigorously. If you know your area is prone to rabbits, we would advise using a rabbit guard.
Ornamental Conifer trees do not require a lot of pruning. Simply remove any dead, diseased or awkwardly placed branches from your Thuya Smaragd conifer as and when you see them.

The product table at the bottom of the page gives the forms and sizes available for this variety. Please note, photos are a guideline as all plants are unique. *Pot sizes may vary. Below are definitions of terms:
Supplied Size: Height measured from the top of the pot.
Single Stem / Pruned and shaped: Classic shaped tree with a single stem that has had pruning to help create a beautiful, natural shape.
Top grafted: A height noted next to this form refers to the length of clear stem, which will not grow taller. Only the head of branches will develop. Top grafted trees do not require complicated pruning and are ideal for small spaces.
Feathered: A feathered tree has branches from the bottom of the trunk all the way up. These branches can be removed if a clear stem is required.
Multi Stem: A multi stem tree has two or more stems arising from or near ground level, growing from one root system.
Bush: A plant with many stems low down, rather than one clear stem.
Clump: Several plants in one pot that can give the appearance of a multi stemmed and very bushy tree.
Climber: A plant that is a natural climber and will be delivered usually running up a bamboo cane, ready to position in the garden.
Standard Tree: A more mature tree with an upright clear stem of approximately 1.8m-2.0m (measured from the soil to the lowest branches of the crown). Standards are available in different forms relating to their girth size (circumference of the stem measured 1m above soil level), not height:
Standard either 6-10cm or 8-10cm girth, approximately 2.5-3.0m in height
Premium Standard 10-12cm girth, approximately 3.0-3.5m in height
Heavy Standard 12-14cm girth, approximately 3.5-4.5m in height
