Characteristics of Thuja Plicata 'Green Giant' – Green Giant Arborvitae

Elevate your landscape quickly and impressively with Thuja plicata 'Green Giant'. Known for its fast growth and towering presence, this evergreen arborvitae is ideal for creating robust, reliable privacy barriers and windbreaks.

Key Features:

  • Rapid Growth: Quickly establishes tall, dense hedges, ideal for large spaces.

  • Rich Evergreen Foliage: Dark green foliage retains vibrant color throughout the seasons.

  • Durable and Hardy: Tolerates a wide range of soils, resistant to drought, pests, and diseases.

  • Adaptable Landscaping: Excellent as a privacy screen, windbreak, accent, or standalone tree.

For best results, plant Green Giant Arborvitae in full sun with moist, well-drained soil

  • Full Sun (Recommended): Green Giant thrives with 6-8 hours of direct sunlight each day. Plants receiving full sun develop thicker, more robust foliage and achieve their maximum growth potential of 3-5 feet annually.
  • Partial Shade (Acceptable): While adaptable to partial shade, the plant requires a minimum of 4 hours of direct sunlight daily. Growth rate may be slower with less dense branching compared to full sun plantings. In regions with intense summer heat, some afternoon shade can be beneficial.
  • Full Shade (Not Recommended): Like most evergreen conifers, Green Giant will struggle in deep shade conditions. Plants become weak, sparse, and fail to reach their full size potential.

Bottom Line: Green Giant adapts to various light conditions but achieves peak performance in full to partial sun locations. Choose the sunniest available spot for fastest establishment and densest screening.

Planting Guide:

  1. Site Selection: Select a sunny or partly shaded site with well-draining soil.

  2. Preparation: Dig a hole twice as wide and as deep as the root ball.

  3. Planting: Position so the top of the root ball is level with ground surface; backfill soil firmly around the roots.

  4. Watering: Deeply water after planting and regularly thereafter to promote strong root growth.

  5. Maintenance: Mulch around the base to retain moisture and prevent weeds; prune as needed in early spring to maintain desired shape and size.

Spacing Guide for Privacy Screening:

  • Plant 5–6 feet apart to form effective, continuous privacy screens.
