- Overwintering Potted Mums:
• Indoor Storage: After the first frost, trim the plant back to about 3-4 inches above the soil. Place the pot in a cool, dark location with temperatures between 32-50°F (0-10°C). Water sparingly to keep the soil slightly moist.
• Outdoor Storage: If indoor space is limited, move the pot to a sheltered outdoor area, such as against a building. Mulch around the pot to insulate the roots. - Mulching:
• Apply a 2-3 inch layer of mulch around the base of the plant after the ground has frozen. This insulates the roots and helps prevent frost heave. - Spring Care:
• Uncovering: As temperatures warm, remove mulch to allow new growth.
• Pinching: To encourage bushier growth and more blooms, pinch back new shoots when they reach about 6 inches tall. Repeat this process until mid-July. - Watering and Fertilizing:
• Watering: Keep the soil consistently moist but not waterlogged.
• Fertilizing: Apply a balanced, slow-release fertilizer in early spring to support growth.
By following these steps, you can transform your fall mums from a one-season wonder into a perennial favorite in your garden.
