Understanding Green Giant Arborvitae

Green Giant Arborvitae, a hybrid cultivar resulting from the cross-breeding of the Western redcedar and the Japanese Arborvitae, is a remarkable tree. With its potential to reach heights of 40-60 feet and a spread of 12 to 18 feet, it serves as an excellent choice for creating natural screens or windbreaks in large properties. The lush and dense foliage of Green Giant is resistant to browning and shedding, making it an attractive privacy option. Moreover, it is also resistant to many pests and diseases, making it an ideal choice for areas with wildlife.

Ideal Growing Conditions

Green Giant Arborvitae thrives in full sun to partial shade, although it prefers exposure to at least six hours of sunlight per day for optimal growth and vitality. It is adaptable to various soil types, including loamy, sandy, and clay soils, as long as they are well-drained. It is crucial to avoid planting Green Giant in areas with standing water or compacted soil, as these conditions can lead to root rot and other problems. Adding organic matter such as compost or peat moss can help improve soil quality and fertility. Avoid planting Green Giant near concrete or other impervious surfaces to prevent root restriction and water runoff.

Planting Thuja Green Giant Arborvitae

Choosing the Right Location

Before planting your Green Giant Arborvitae, carefully select the best spot in your landscape that meets its growing requirements and suits your landscaping goals. Green Giant works well as a specimen tree, hedge, or windbreak, depending on how you space and prune it. For privacy screens or natural fences, plant it in a row spaced at least 10 feet apart to allow for maximum growth and coverage. Avoid planting Green Giant too close to buildings, power lines, or other structures that can interfere with its height and spread.

Preparing the Soil

The next step in planting Green Giant is preparing the soil. Start by clearing the planting site of weeds, grass, or other debris. Loosen the soil to a depth of at least 12 inches using a shovel or tiller, ensuring there are no clumps of dirt or foreign objects that can hinder root growth. Test the soil pH and nutrient levels using a soil test kit, and adjust them according to the recommendations provided. Adding a slow-release fertilizer can provide essential nutrients for Green Giant during its initial growth stages.

Planting Steps and Techniques

Once the soil preparation is complete, it’s time to plant your Green Giant Arborvitae. Follow these steps for optimal results:

  1. Dig a hole that is twice as wide and equally deep as the root ball of the young tree.
  2. Lower the root ball into the hole, ensuring that the top of the root ball is level with the soil line.
  3. Backfill the hole with the soil mixture, gently tamping it around the roots to eliminate air pockets.
  4. Water the newly planted tree thoroughly to saturate the roots and settle the soil.
  5. Apply a layer of mulch, such as wood chips or shredded bark, around the base of the tree, leaving clearance around the trunk to prevent moisture retention and pest damage.

Spacing and Arrangement Tips

To create a well-spaced and attractive screen or hedge, consider the mature sizes and shapes of Green Giant Arborvitae. Space the trees 10 to 12 feet apart between rows and 4 to 6 feet apart within rows for optimal growth and coverage. Vary the spacing based on your preferences and the landscape’s needs. Use stakes and strings to mark the planting locations before digging to ensure the trees are straight and evenly spaced.

Caring for Thuja Green Giant Arborvitae

Watering Requirements and Techniques

Green Giant Arborvitae has moderate water needs and can tolerate periodic droughts once established. However, regular watering during its first year after planting or during hot and dry spells can promote healthy growth and prevent stress. Water the tree deeply and infrequently, applying 1 inch of water per week or more during extremely dry periods. Check the soil moisture regularly and water if the soil feels dry.

Fertilizing Your Arborvitae

Green Giant Arborvitae does not require heavy fertilization, but it can benefit from a nutrient boost from time to time. Fertilize your tree once a year in late winter or early spring before new growth begins or in fall after the tree sheds its needles. Use a slow-release granular fertilizer that contains nitrogen, phosphorus, and potassium, applying it according to the package directions. Water the tree well after fertilization.

Pruning and Shaping

Green Giant Arborvitae requires minimal pruning, other than removing any dead, diseased, or broken branches as soon as they appear. However, you can shape and trim your Green Giant to enhance its aesthetic appeal or control its size and shape if necessary. Prune your tree in late winter or early spring before new growth appears, using sharp and clean pruning tools to make clean cuts.

Pest and Disease Management

Green Giant Arborvitae is relatively pest and disease-resistant, but it is not immune to certain problems that can affect its health and appearance. Monitor your tree regularly for signs of infestations or damage, such as webbing, discoloration, or defoliation, and address them using appropriate insecticides or pesticides if necessary. Some common diseases that can affect Green Giant include root rot, canker, and blight. Avoid overwatering or creating a moist environment near the trunk or branches to prevent fungal growth.

You can also wrap your tree with burlap or a frost cloth to protect it from wind and cold weather, especially if you recently planted it or live in an area with harsh winters.

Spring Maintenance

Spring is an active growing season for Green Giant Arborvitae. Check its health, remove any dead or damaged branches, and fertilize it.
