How to Move an Established Shrub (Timing and Root-Ball)
The short answer
Move established shrubs while they're dormant — fall or early spring. As a rule, transplant spring/early-summer bloomers in fall, and late-summer/fall bloomers in early spring, so you're not disrupting the plant right before it flowers. Dig the widest root ball you can realistically move: aim for a ball roughly as wide as the shrub's canopy, or about 1 foot of root-ball diameter for every 2 feet of shrub height on upright plants.
The whole job hinges on keeping roots moist. Replant immediately at the same depth it grew before, water in thoroughly, and mulch. For a large shrub, root-prune the season before by cutting a ring around the future root ball, which encourages a denser root system inside the ball you'll eventually lift.
When to move it
- Best windows: fall (after leaves drop) or early spring (before growth starts), while the plant is dormant.
- Spring and early-summer bloomers: move in fall.
- Late-summer and fall bloomers: move in early spring, just as they break dormancy, so roots establish before flowering.
How to dig and move it
- 1Size the root ball — Dig a root ball about as wide as the canopy; for upright shrubs, allow ~1 foot of ball diameter per 2 feet of height. Bigger is better — most feeder roots are near the surface, out toward the drip line.
- 2Root-prune large shrubs ahead of time — For big or long-established shrubs, dig a trench in a ring 8-12 inches wide the season before the move; the outer wall becomes the edge of next season's root ball, and the shrub grows new roots inside it.
- 3Lift and keep moist — Undercut the ball, lift it onto burlap or a tarp, and keep the roots moist and shaded until replanting. Roots that dry out die.
- 4Replant at the same depth — Set it in the new hole at the same depth it grew before — don't bury the root flare — backfill, water in thoroughly, and mulch.
⚠ Don't let the root ball sit and dry between digging and replanting. If you can't replant right away, keep it in the shade with the roots covered and moist.
