Transplanting a 12-Ft Spruce on a 3:1 Slope: Root Ball Size and Timing

Root Ball Specs

3.5-inch caliper → root ball 31.5–42 inches wide × 21 inches deep. New hole: 2× ball width, same depth.

Timing

• Spring preferred (before bud break).
• Fall OK if ≥6 weeks before ground freeze and not in a snow belt.
• August is risky—heat stress on a large transplant.

Procedure

1. Pre-dig destination hole.
2. Dig tree, keep ball intact, wrap in wet burlap.
3. Move on trailer, plant same day.
4. Backfill with topsoil, mulch, water 1 inch weekly.

Protect roots from wind/sun during move. A few men + trailer can work if ball is manageable (~1,000+ lbs).
