Moving Overgrown Mums: Timing and Technique for Minimal Shock

Optimal Transplant Window

Fall: 30–45 days before first frost (allows root establishment).

Spring/Summer: Possible now—cut back to 6", dig generous rootball, replant immediately.

Step-by-Step

1. Cut stems to 6 inches.
2. Dig 12–18" out from crown to capture fibrous roots.
3. Replant at same depth; water thoroughly.
4. Mulch and water weekly if dry.

Expectations

• Plants will regrow and bloom in fall (if moved now).
• Mums tolerate transplanting well compared to many perennials.

For future size control, pinch stems in early summer (before July 4) to promote branching and shorter stature.
