Mum Planting Guide

Excited for your fall blooms? You’re in for a treat! Whether you’re nurturing spring plant plugs or newly purchased established plants, let’s make sure your mums flourish. Here’s your go-to guide!

What You Need to Know

Mums are tender perennials, meaning they can return year after year if planted correctly. They thrive in specific growing zones and require attention to their light needs. Mums are photoperiodic, blooming when the days shorten, so understanding their care will help you enjoy their vibrant display!

To determine your growing zone, checkout the USDA’s Plant Hardiness Zone Map.

In some areas, bloom times may be after the threat of killing frost. If you're located in an area that has an early frost, we recommend planting the mums in portable containers so they can be moved indoors as needed. Knowing the growing zone specific to your geographic location will help you in planning how to enjoy these fall beauties.

Planting Options

1. For Plant Plugs (Spring Shipping):

  • Transplanting: Use pots at least twice the size of the plugs (quart-sized recommended).

  • Soil: Fill with all-purpose potting soil. Plant the mum so the root ball is covered, keeping the foliage above soil level.

  • Environment: Keep in a cool area (above 45°F) with indirect sunlight. Water lightly every few days, ensuring the soil is moist but not soggy.

  • After Frost: Once the threat of frost has passed, you can transplant into the garden or larger containers.

2. For Established Plants (Fall Purchase):

  • Immediate Planting: Plant your mums as soon as you get them home to ensure they establish well.

  • Location: Choose a sunny spot and plant the root ball completely covered, with foliage above ground.

  • Watering: Regularly water, as mums have shallow roots and can dry out quickly.

Ongoing Care

  • Pruning: Trim the tips of stems early in the season to encourage branching. Avoid pruning after early July to allow growth for flower height.

  • End of Season: Remove dead foliage after the first frost. Cut back to about 4 inches.

  • Dividing: As your mums grow, consider dividing them to promote healthy growth.

Bloom Insights

Mums will bloom at different times based on their variety, climate, and care. Expect blooms to appear in the fall, typically 6–10 weeks after the nights grow longer.

For best results, keep an eye on local frost dates and adjust your care accordingly. Enjoy your beautiful mums and thank you for supporting American Grown Flowers!
