Why should you plant Thuja Green Giant?
Instead of a boring ugly fence, you can have a stately living privacy barrier when you plant a Thuja ‘Green Giant’ (Thuja standishii x plicata ). Since they are evergreen, you will have vibrant color throughout all four seasons. These trees naturally form into conical shapes and rarely need any pruning.
One of the greatest features of Thuja Green Giant is how carefree it is. Pests and diseases usually pass on by this tree. You will not have to spray chemicals with this conifer. Even deer prefer not to nibble on this plant!
One you have given it a chance to develop roots and settle in, it can tolerate drought periods. Whether your oil is light sand or heavy clay, as long as their is drainage this arborvitae can handle them all!
Pollution can cause many problems for trees in urban locations. The Green Giant Thuja is tolerant of this problem, making it an excellent choice for a city tree.
Because of its many positive characteristics, it was awarded the Pennsylvania Horticultural Society’s Gold Medal Plant Award in 1998. Over the years this has come to be THE species to grow as a living fence.
How fast do Green Giants grow?
After a year of proper watering and care to help the roots establish, you can expect your Green Giant to grow at a rapid rate of 3-5 feet per year. There are few trees that can match this! At maturity, your tree will be 20-60 feet tall.
What are the problems for Thuja Green Giant?
You may find that some of the needles turn brown in the middle of the tree, but this is usually natural. This can happen in winter when cold winds dry out the foliage, or if the Thuja has been in drought conditions for an extended length of time. If chemicals are sprayed near these trees, especially in hot weather, it may also cause this problem.
If you have leaky pipes, it is slightly possible that the fibrous network of roots could grow towards them and cause further damage. As long as your structure is intact, though, you should not have any problems. This tree will not crack driveways or sidewalks, either.
Heavy snows could potentially cause some problems, though this variety is very resistant to snow and frost damage.
What Trees Might Work Better Than Thuja Green Giant?
There are few, if any, trees that can come close Thuja Green Giant when it comes to creating a privacy screen. This variety is now used as an attractive substitute for the Leyland cypress (Cupressus x leylandii), which is more problematic.
If you want to try a different variety of Thuja with a similar habit, you could try Green Splendor.
For a deciduous privacy species, you could use the fastigiate European hornbeam (Carpinus betulus ‘Fastigiata’). It is also generally free from pests, diseases, and the need for pruning.
How do I plant them for the fastest privacy?
For the fastest privacy screen you should choose the tallest trees that your budget will allow. You should also plant them 5-6 feet apart so they grow together more quickly. Keep them properly watered to encourage strong roots and maximum growth.
When is the best time to plant?
These trees should be planted in early spring for optimal results. It is possible to place them in the fall, but frost damage or chilly winds may hamper the growth of your new plant. Fall planting will be more successful in the warmer USDA zones as long as they are placed at least 6 weeks before the first expected frost date. Contact your local nursery or extension service to determine when that will be.
Where do they grow the best?
Gardeners in USDA Zones 5-9 will find the best success in growing Thuja Green Giant. The fastest growth will occur in full sun, but you can plant in a location that receives part shade.
How many trees will I need?
Each Thuja will have a mature width of 8-12 feet. Measure the length of the area where you want to grow these trees and divide by 8. If you are going for especially fast privacy coverage, divide by 5 feet. Round to the nearest whole number and you will have the number of trees you need to buy.
What do I look for when buying Thuja Green Giant?
Choose a sturdy straight tree that has developed one main central branch, which is called a leader. This will help ensure the best pyramidal form.
Inspect the root ball when possible to make sure it is properly developing. If it is in a container, gently slide it out. The soil should stay intact around the football. It should not have roots circling on the outside as they will continue to grow in this manner even after planting and cause problems.

Thuja Green Giant Planting Directions When your Thuja Green Giant arrives, carefully remove it from its packaging and set it in a shady location.
Tips for Planting Success:
Thuja Green Giant has a mature height of up to 60 feet and reaches spreads of 12-20 feet. This is a large tree. Before you plant it, determine if the area will accommodate the mature size of the tree.
- If you intend to create a privacy hedge, you will need to space your trees at least five feet apart.
- Water the tree in its original pot before you transplant to help loosen the roots and make it come out of the pot easier.
- Gently loosen the roots to give them growing room immediately prior to transplanting.
- Follow general planting directions and water in well. Pay special attention to the drainage of the hole you just dug as Thuja trees do not tolerate standing water. »
- Place hardwood mulch around the tree’s perimeter (cypress mulch) to help hold moisture in. Leave three inches around the tree trunk clear of mulch so that mulch does not touch the trunk. Then add mulch to a level of three inches deep, one or two feet outward from the tree. »
- Water deeply every other day for the first two weeks, and then you may taper back gradually to every third day the next two weeks, and once a week thereafter. We consider a once-weekly “deep” watering to be much better than frequent shallow watering. Water your tree at the root or ground level, not by misting from overhead. This will cut down on the potential for fungus-related diseases. If you experience drought conditions, more watering may be necessary. A good rule of thumb for deep watering is to hold the hose to the ground around the roots while you slowly count to at least 20.
- Fertilizing and pruning are not necessary, unless you have specific problems that you need to address.
Follow these general instructions and you will ensure success with your Thuja Green Giants.
