If you are looking for a fast-growing and evergreen tree that is resistant to the bagworms and deer, then look no further than Thuja green giant arborvitae. The Thuja green giant arborvitae also acts as an excellent focal point evergreen either as a grouping or a specimen. It is a fast growing tree that grows to 35 feet high in seven years. It takes the shape of a cone and stays green throughout the year even during winter. This is because it is resistant to snow and ice load damage.
This thuja tree is close to perfect as far as the hedging tree is concerned. During the first year after they are planted, the trees establish their roots. After the first year, their subsequent growth will grow depending on some factors. Some of these factors include the amount of sunlight that they receive and how they are pruned and maintained.
With the right care, they will add between four and nine inches in height and between two and six inches in width. It is, therefore, critical to note that if you are planting these trees for privacy reasons, then you have to wait patiently for some years. If you need instant privacy, then you may need to buy bigger trees rather than the seedlings.
Bushy and skinny species
These trees are cylindrical coniferous trees. If they are allowed to grow without being pruned, they will grow thin and tall. However, if they are pruned on top, they will not increase in height but will get bushier. The gardener, therefore, has a choice on whether he wants the tree thin and tall or bushy. Many people usually allow the tree to grow without pruning them.
For the skinny species, the gardener will need to plant the trees close together or wait for few years before they fill in the spaces. The trees that are grown in a container are usually skinny and tall. The concern is usually how to transplant the overgrown tree.
How far should they be planted?
The rule of the thumb should be applied when planting the green giant arborvitae; which is two feet between two trunks. Some individuals usually prefer planting the trees close together so that there are no gaps, but there are those who plant them further apart and fill them later. The width of the tree will determine whether the much-desired privacy will be achieved. If you buy narrower species of this tree, then you should know that you will have to plant them close together.
