Pinching Mums: Timing, Transplanting, and Frost Safety

Early Growth = Early Pinching

Mums at 5–6 inches in early spring (due to mild winter) should be pinched now. But coordinate with transplanting:

Pinching Schedule

• Plants staying put: Pinch now.
• Plants moving Saturday: Transplant first, wait 10 days, then pinch.

Why Wait After Transplant?

Cutting tips triggers regrowth energy. Damaged roots need that energy for repair. Pinching too soon = double stress = plant decline.

Frost and Fresh Transplants

If heavy frost forecast: DON’T MOVE. Newly disturbed roots in cold soil = root kill. Wait until frost-free date.

Pinching Technique

1. Remove top 1–2 inches of each stem (above a leaf node).
2. Repeat every 2–3 weeks until July 4th.
3. Stop by July 4th for fall buds.

Pro Tip

Pinch with fingers (not shears) for clean break. Sanitize if disease present.

Your mums will be tighter and flower-heavier come autumn. Patience on the moves.
