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

To successfully plant a Thuja Green Giant tree, choose a location that receives ample sunlight and has well-draining soil to ensure optimal growth. Start by digging a hole that's double the width of the tree's root ball and as deep, which encourages root growth and provides a strong foundation. Carefully place the Thuja Green Giant in the center of the hole, aligning the top of the root ball with the existing soil line to promote proper growth. Mix the excavated soil with rich compost before backfilling to enrich the planting site and support healthy development. Water the tree deeply to settle the soil around the roots and eliminate air pockets, and continue to provide consistent moisture, particularly in the first growing season, to establish a resilient root system. Adding a layer of organic mulch around the base can conserve moisture, suppress weeds, and maintain soil temperature.

How to fertilize a Thuja Green Giant

How to fertilize a Thuja Green Giant

Fertilizing your Thuja Green Giant tree is essential for maintaining its lush, vibrant growth and overall health. For optimal results, apply a balanced, slow-release fertilizer such as Holly-tone by espoma, in the early spring, just as the growing season begins. This will provide a steady supply of nutrients throughout the most active growth phase. Ensure that the fertilizer contains a mix of nitrogen, phosphorus, and potassium to support foliage development, root strength, and overall tree vitality. It's important to follow the manufacturer's instructions regarding the amount and frequency of application to avoid over-fertilizing, which can harm the tree. Additionally, watering the tree after applying fertilizer helps distribute the nutrients evenly around the roots. Regularly feeding your Thuja Green Giant with the right fertilizer can significantly enhance its growth and ensure a healthy, robust appearance for years to come.

How to water Thuja Green Giant

How to water Thuja Green Giant

Proper watering is crucial for the health and growth of your Thuja Green Giant tree, especially during its establishment period and in times of drought. After planting, water your Thuja Green Giant deeply and regularly, about once per week, to encourage deep root development, which is vital for long-term health and stability. As the tree matures, it becomes more drought-tolerant, but maintaining consistent moisture in the soil can greatly enhance its growth and vitality. Utilize a soaker hose or watering bag to deliver water directly to the base, ensuring thorough saturation of the root zone without wasting water. During hot, dry spells, increase the frequency of watering to keep the soil evenly moist but not waterlogged. Monitoring soil moisture levels before watering can prevent both under and over-watering, preserving the Thuja's health and promoting lush, green growth throughout the seasons.

How to Mulch a Thuja Green Giant

How to Mulch a Thuja Green Giant

Mulching regularly will enhance the growing conditions for your Thuja Green Giant tree. Apply a 2-3 inch layer of organic mulch, such as hardwood mulch or pine needles, around the base of the tree, extending out to the drip line. This layer of mulch helps to retain soil moisture, suppress weeds, and regulate soil temperature, providing a more stable environment for the roots. Be sure to leave a small gap around the trunk of the tree to prevent moisture buildup, which can lead to bark rot and other diseases. Refreshing the mulch annually also adds nutrients back into the soil as it decomposes, further boosting the Thuja Green Giant's growth and health.


Additional Information

If you've had problems with Leyland Cypress in the past you can replace your Leyland Cypress trees with Thuja Green Giants and this  can be a wise decision for several reasons. Leyland Cypresses are susceptible to a variety of diseases and bagworm attacks, which can weaken and even kill these trees. In contrast, Thuja Green Giants are notably more disease-resistant and robust, offering greater durability and lower maintenance requirements. Additionally, Thuja Green Giants are better suited to a wider range of soil types and environmental conditions, including both dry and wet climates. Their fast growth rate and dense foliage provide quick privacy and effective windbreaks, similar to Leyland Cypresses, but with fewer health issues. The adaptability and resilience of Thuja Green Giants make them an excellent alternative for those looking for a reliable, long-term solution for landscaping, particularly in areas where Leyland Cypresses have struggled.

How to create a privacy screen with Thuja Green Giants

Using Thuja Green Giants to create a privacy screen is an excellent choice due to their dense foliage and rapid growth rate. These evergreen trees can grow up to 3 to 5 feet per year, quickly forming a solid green barrier that offers substantial privacy. Thuja Green Giants are ideal for this purpose because they maintain a uniform, conical shape that requires minimal pruning, making them low maintenance. They can be planted in a straight line or staggered pattern, depending on the desired thickness and immediacy of the privacy screen. Their height, which can reach up to 60 feet, and their spread of 12 to 20 feet at maturity, ensure a high, wide coverage that is perfect for enclosing backyards, lining property boundaries, or shielding unsightly views, all while adding aesthetic value to the landscape.

Planting a Sound Buffer or Wind Break

Thuja Green Giant trees are highly effective when used as a windbreak or sound buffer due to their dense growth and tall stature. To create an efficient barrier against wind, plant these trees in a single row or a staggered double row where space allows, positioning them about 5 to 6 feet apart. This spacing ensures that the trees grow together to form a tight, continuous screen. As Thuja Green Giants can reach heights of up to 60 feet, they can significantly reduce wind speed and deflect it upwards and around a property rather than allowing it to pass through. This natural barrier also helps in dampening traffic noise, machinery sounds, and other environmental noise pollutants, making it ideal for properties near busy roads or industrial areas.
