AvatarByMichael Rigg Eco-friendly living

When it comes to creating a lush, green landscape, few trees are as popular and versatile as the Green Giant Arborvitae. Known for its rapid growth and impressive height, this evergreen is a favorite among homeowners looking to establish privacy screens, windbreaks, or simply add a touch of natural beauty to their gardens. However, achieving the perfect look and health for your Green Giants starts with one crucial decision: how far apart should you plant them? The spacing of these majestic trees can significantly impact their growth, aesthetics, and overall health, making it essential to understand the best practices for planting.

Planting Green Giant Arborvitae at the right distance is key to ensuring they thrive in your landscape.

  • Moisture: Green Giant Arborvitae prefer consistently moist soil but can tolerate short dry spells once established.

Planting Depth and Technique

Proper planting technique is essential for the healthy establishment of Green Giant Arborvitae. The planting depth should allow for the root collar (where the roots meet the trunk) to be level with the soil surface.

Follow these guidelines for planting:

  • Dig a Hole: The hole should be twice as wide as the root ball and the same depth as the root ball.
  • Amend Soil: If soil quality is poor, mix in organic matter to improve drainage and nutrient content.
  • Watering: Water thoroughly after planting to eliminate air pockets and ensure good contact between the roots and soil.
