Green Giant Arborvitae Shade Tolerance

Green Giant (Thuja plicata 'Green Giant') performs best in full sun to partial shade. Deep shade stunts growth—it needs minimum 4-6 hours direct sun for dense, vigorous form.

Light Requirements

• Full sun: Maximum growth rate (3-5 ft/year), densest foliage
• Partial shade: Good growth, slightly open habit
• Full shade: Slow, leggy, poor screening value

Key Characteristics

• Western redcedar hybrid—naturally shade-tolerant species
• Deer resistant (unlike most arborvitae)
• Windbreak excellence—flexible branches shed snow/ice
• Decay-resistant wood, but brittle—avoid heavy ice loads

Planting Considerations

Site away from quiet deer browsing areas (near structures, lights, roads). Space 5-6 ft for hedges, 10-12 ft for specimens. Your partial shade site may work if it receives morning sun or dappled light all day.
