Thuja Green Giant Arborvitae for Sale Online

Thuja Green Giant Arborvitae (Thuja plicata x standishii), more commonly known as Western Red Cedar, are pyramidal evergreen trees known for their fast-growing habit, lasting color, and lush green foliage. They grow well in just about all parts of the United States.

Known as the fastest-growing privacy tree, this evergreen tree can reach a mature height of 60 feet and 14 to 18 feet wide if left untrimmed. Its bright green color persists year-round, enhancing curb appeal while creating protective barriers and privacy with its dense foliage. Green Giant Arborvitae are excellent for use as a sound barrier due to their dense foliage, which can reduce noise from busy roads or loud neighbors. 

Unlike some evergreen trees, Thuja Green Giant trees have few pest and disease problems. It's known to be deer-resistant no matter where it's planted in your yard. Green Giant tolerates a wide range of soil conditions, even drought. While Arborvitae trees grow best in full sun, they can endure in partial shade, but they will have a more open growth habit.

Thuja Green Giant is recognized as an Elite Plant by the US National Arboretum and has been granted the prestigious gold medal by the Pennsylvania Horticultural Society.

How to Care for Thuja Green Giant Arborvitae

Once you buy an Arborvitae Green Giant, follow the planting and care instructions below for the best outcome:

HOW TO PLANT An Arborvitae Green Giant

HOW TO PLANT An Arborvitae Green Giant

This Arborvitae does best when grown with a single leader, and extra main stems should be removed before planting. If you plant Thuja Green Giant it in a wet area, it is suggested that the top of the root ball be placed roughly on an inch or so above the existing soil level. Otherwise, we typically recommend using the pot it was delivered in as a guide for measuring how deep to dig the planting well (approximately 8-12 inches deep) for traditional soil. Planting it deeper than the pot it was delivered in can cause rotting of the stem and death to the tree. Remove enough soil from the hole or trench so that the plants sit just an inch or so below the final level of the ground. It’s best if the soil underneath is firm so that your plant will not be pushed deeper as you plant.

HOW TO FERTILIZE A THUJA GREEN GIANT ARBORVITAE

HOW TO FERTILIZE A THUJA GREEN GIANT ARBORVITAE

When it comes time to fertilize your Arborvitae Green Giant, we recommend Espoma Bio-Tone Plus Starter Plus fertilizer. We have tried many so-called “starter fertilizers” over the years and have come to rely on this one exclusively for our use. Simply mix the recommended amount of Bio-Tone Plus Starter Plus into the back-fill soil and water in generously when back-filled. We recommend adding fertilizer to the soil when the tree is freshly planted in its new home in your garden, and during early spring to give it the extra boost it needs to flourish and grow after the winter season. This will give new branches and foliage a chance to kick start growth before the season ends.

HOW TO WATER Arborvitae Green Giant

HOW TO WATER Arborvitae Green Giant

For the first few weeks after planting, water your arborvitae by counting 5 seconds for every gallon in the pot it was delivered in (if your tree was delivered in a 3-gallon pot, you would water the tree for 15 seconds). Once the tree has had a chance to settle, you can reduce the frequency of the watering schedule. An easy way to determine this is to check the soil moisture yourself. It’s as simple as sticking a gardening tool in the ground and feeling the soil with your fingers - if it’s damp, you may want to wait a day to water it again.

HOW TO MULCH THUJA GREEN GIANT ARBORVITAE

HOW TO MULCH THUJA GREEN GIANT ARBORVITAE

Mulching is not necessary but is highly recommended. This technique helps to keep weeds away which will compete with the tree for the water and nutrients it receives. We recommend using a high quality mulch made from ground hardwood or cypress. As you lay the mulch on top of the soil, leave an inch of space between the mulch and the base of the tree trunk. A 2 to 3-inch layer of mulch is sufficient but remember to take care not to cover any part of the stem of the plant with mulch.


Additional Information

If you’ve had problems with the Leyland Cypress or Emerald Green Arborvitae in your yard, this plant is a great replacement. The smooth, delicate, dark-green foliage emits a pleasantly sweet aroma when crushed. What’s the point in planting a beautiful tree if you have to cover it up with burlap or deer netting every winter? This tree does just fine without those ugly protections.

Arborvitae Green Giant trees are known for their ease of care and low maintenance, which makes them so popular. This class of trees is a perfect choice for any homeowner who has a busy or inconsistent schedule but still wants to enjoy the beauty and benefits of live plants.

How to create a PRIVACY SCREEN

If the goal is to create a privacy screen around your home or property, we recommend planting Green Giant Arborvitaes in a line with about 8 feet apart from each other to create quick privacy. However, they can be planted at 10 to 12-foot intervals if you don’t mind waiting a bit for privacy; planting them closer together will reach the privacy goal faster.

Planting a Sound Buffer or Wind Break

Arborvitae Green Giant trees make an excellent windbreak, standing up to the strongest of winter winds, due to its substantial root system. Windbreaks are a perfect way to reduce your heating bills in the winter time by blocking the cold winds that sneak into the house and create a cold environment. When planted in a staggered row, this tree can also act as a sound buffer and reduce noise coming from busy streets, loud neighbors, or anything else that can be disturbing your peace.

When creating a windbreak or privacy hedge, it's essential to know how far apart to space your plants. Remember, it is a pyramidal tree and can reach up to 60 feet tall and up to 18 feet wide so it’s important to give Thuja Green Giant trees ample room to expand allowing for symmetrical growth.

Plant one row of trees with another row 6 to 8 feet in front of the first row filling in the gaps between the plants. This method creates instant privacy and will virtually eliminate unwanted sounds or wind once it fills in. See the diagram below for an example of the staggered planting pattern:
