Junior Giant Arborvitae for Sale Online

Junior Giant Arborvitae trees boast the same qualities you love about our best-selling Thuja Green Giants but in a smaller, more manageable form for secluded landscapes.

Sporting deep green foliage and a pyramidal uniform shape, the Junior Giant Thuja tree is a rich addition to any landscape. Reaching a mature height of 15 to 20 feet, as opposed to a 60-foot tall green giant, the Junior Giant brings great coverage to an outdoor space without entirely overwhelming it. 

The Junior Giant is best suited for hardiness zones 5-8. Best care practices for the Junior Giant include well-drained soils, full sun, and the application of a slow-release fertilizer in the growing seasons of spring and summer. Additionally, we recommend you water the tree regularly until it is established. 

While these trees are incredibly hardy to the elements and can withstand freezing temperatures and extreme weather conditions, your Thuja Junior Giant would benefit from the application of mulch around the base of the plant, especially in the winter and summer months. Mulch works to conserve moisture and protect the rootball in extreme conditions.

If you have limited space in the yard but want to install evergreen privacy, the Thuja Junior Giant Arborvitae is the way to go! Beyond their perfect size and form, these trees are known for their fast growth rate, lasting color, and lush foliage.

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.

Junior Giant Arborvitae 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 Junior 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

Junior 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. 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 Junior Giant Arborvitae 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:
