Newly Planted Green Giant Arborvitae Leaning on a Slope: Stake or Wait?

Assessment

A slight lean (under 20° from vertical) on a recently planted Green Giant on a slope is normal. The tree will self-correct as roots establish.

When to Stake

• Lean >20° from vertical.
• Root ball shifting in soil.
• Exposed, high-wind site.

Proper Staking (If Needed)

1. Two stakes perpendicular to prevailing wind.
2. Flexible ties (wide fabric or hose-covered wire) at ⅔ height.
3. Allow slight trunk movement—this stimulates root growth.
4. Remove stakes after one growing season.

Bottom Line

Your tree sounds fine. Replanting damages more roots than a slight lean. Mulch, water 1 inch/week, and monitor.
