About Your Thuja Green Giant Arborvitae Trees

Benefits of Buying Thuja Green Giant Trees


Highly Tolerant & Resistant

Unlike some evergreen plants, the Thuja Green Giant has few pest and disease problems. Green Giants are one of the most tolerant and resistant trees sold today for many different uses. For those that live in the mountains or areas that have a lot of wildlife traffic, you’ll be pleased to know that Green Giants are deer-resistant, so you won’t have to worry about forest critters eating its branches and vibrant greenery.

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.

Low Maintenance

Green Giant Arborvitae trees are known for their ease of care and low maintenance, which makes them so popular. This class of trees are 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.

Windbreak Privacy Hedge

Green Giant arborvitae 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. They can also be used to block the low setting sun in the evenings - this can heat the outer walls of homes and comes through the windows and raises the temperature in a room quickly.

Planting Information

After you buy a Thuja Green Giant, follow the planting and care instructions below for the best outcome:

HOW TO PLANT A THUJA GREEN GIANT ARBORVITAE

HOW TO PLANT A THUJA GREEN GIANT ARBORVITAE

Green Giants tolerate a wide range of soils including sandy soils, wet sites, and heavy clay soils which are typically poorly drained soils. When planting 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. When planting this tree in regular, well draining soil, we do not recommend planting it deeper than the pot it was delivered in because this 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 - laying a stick across the hole is a good way to check this. It’s best if the soil underneath is firm, so that your plant will not be pushed deeper as you plant. When planting Green Giant Arborvitaes, the spacing matters for what you’re trying to achieve:

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.


Sound Buffer or Windbreak

An added benefit that Green Giant Arborvitaes bring is noise canceling or windbreak abilities. When planted in a staggered row, this tree can act as a sound buffer and reduce noise coming from busy streets, loud neighbors, or anything else that can be disturbing your peace. If you live in a windy area, the dense foliage and sturdy trunks of this tree can also provide protection from elements as a windbreak.

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

Plant one row of trees and then plant 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:

HOW TO FERTILIZE A THUJA GREEN GIANT ARBORVITAE

HOW TO FERTILIZE A THUJA GREEN GIANT ARBORVITAE

When it comes time to fertilize your Green Giant Arborvitae, our recommendation has consistently been to use 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. This is an all-natural plant food that is combined with a stronger concentration of our beneficial bacteria along with both endo and ectomycorrhizae. The “good” fungus in Bio-Tone Plus Starter Plus colonizes on the growing roots of your newly planted plant and does not allow the disease-causing fungus to attack the new roots. It has also shown promise in stimulating the growth of the new roots which means a quicker establishment for your plant. 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 THUJA GREEN GIANT ARBORVITAE

HOW TO WATER THUJA GREEN GIANT ARBORVITAE

We like to follow this helpful tip when watering our own plants, as well as providing recommendations to others on how to properly water a Thuja Green Giant tree for the first few weeks after it’s been planted: count for 5 seconds for every gallon in the pot it was delivered in. So 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 after a few weeks, you can reduce the frequency of the watering schedule. Thoroughly watering the plant in its first phase of life is essential, but after that, you run the risk of overwatering the tree and increasing the chance for root rot. It’s okay to check back on the tree every other day between watering to see if it needs additional moisture. 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

Is mulching necessary? No, but it’s highly recommended. This technique helps to keep weeds away which will compete with the tree for the water and nutrients it receives, essentially taking it away from the Green Giant Arborvitae. While any mulch will do the job, we recommend using a high quality mulch made from ground hardwood or cypress (this depends on your local availability). 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 (don’t press it against it). 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.
