Potted mums are more vulnerable to freezing temperatures than those planted in the ground. Without proper winterization, their roots can freeze, preventing regrowth in spring. Follow these steps to protect your mums and ensure they survive the winter.

Step 1: Stop Pruning After the First Frost

• Once mums start wilting, leave the stems and leaves intact for insulation.
• Do not cut back the plant until spring.

Step 2: Move the Pot to a Sheltered Location

• Place the pot in a garage, shed, basement, or unheated greenhouse.
• If left outside, move it to a protected spot, like next to a wall or under a porch.

Step 3: Insulate the Pot

• Wrap the pot in burlap, bubble wrap, or blankets to prevent root freeze.
• For added protection, place the pot inside a larger container filled with mulch or straw.

Step 4: Apply a Thick Layer of Mulch

• Add 3–4 inches of straw, pine needles, or shredded leaves over the soil.
• This helps retain moisture and warmth during winter.

Step 5: Water Lightly Throughout Winter

• Keep the soil slightly moist, but don’t overwater.
• Water once a month if stored indoors to prevent roots from drying out.

Step 6: Bring Mums Back Out in Spring

• Once temperatures stay above 50°F (10°C), move the pot outside.
• Trim dead stems and wait for new green shoots to appear.

Conclusion

Winterizing potted mums is essential to protect their roots from freezing. By moving them to a sheltered spot, adding insulation, and watering occasionally, you’ll increase their chances of blooming again in spring.
