Thuja 'Green Giant' Hedge Spacing: 4–5 Feet for a Solid Screen

Will Planting Green Giants 4–5 Feet Apart Cause Long-Term Problems?

A follow-up to a question about planting 100 Green Giants (5-gal, 4 ft) for a 600–1000 ft privacy hedge on cleared land in full sun.

Spacing for a Hedge vs. Specimens

• 4–5 feet apart: Trees grow together into a continuous green hedge. No negative health effects; this is the standard for quick screening.
• 8–10 feet apart: Trees remain distinct individuals.
• Staggered double row (8–10 ft between rows, 8–10 ft within rows): Creates a wider, denser screen if space allows.

Planting Tips

• Dig hole twice the root ball size.
• Backfill with good topsoil.
• Mulch and water well.

Bottom Line

4–5 ft spacing is ideal for a fast, solid hedge. The trees will merge beautifully and remain healthy.
