Introduction:
As a dedicated gardener managing the greenhouse at the Akron Lumber Company, I must confess that despite my love for all things spring and green, there's something undeniably enchanting about fall. The crisp morning air, the allure of pumpkins, and the charm of chrysanthemums, or 'mums' as they're commonly known, all resonate with my soul. But as the fall season arrives, questions often arise about the fate of recently purchased mums. Can they be planted in the ground, will they return next year, or should they be kept in pots to regrow? Here in Akron, IA, situated between hardiness zones 4b-5a, the answer isn't straightforward due to our variable winters. We experience temperatures as cold as -20 to -25 degrees Fahrenheit, and sometimes, snow covers the ground for months, while in other years, snowfall is scarce.

Caring for Mums in Your Garden:

1. Planting in the Ground:
   If you wish to plant your mums in the ground after a fall purchase, the ideal time is in August or early September when the threat of a hard frost is still a few weeks away. Mums have shallow root systems, so they need ample insulation to protect their delicate roots from freezing. After planting, apply a 2-3" layer of organic mulch, such as hay or leaves, around the base of the plant. Following the first hard frost, add another 2-3" layer of mulch to create a 6"-12" circle surrounding the plant. Regular watering is crucial until the ground freezes. In late fall, allow the foliage to dry naturally without trimming it. Keeping the dead foliage on the plant might improve its chances of thriving in the spring. Once new growth emerges, trim back the dead stems and foliage.

   Note: Even with proper mulching and early planting, a harsh winter can still be detrimental to mums.

2. Potted Mums:
   If you purchase mums later in the season or prefer to keep them as container plants or plant them in the spring, follow these steps for success. Upon bringing them home, consider repotting them into larger containers to allow for root expansion. Throughout the blooming season, use shears to remove dead blooms to stimulate new growth and ensure the roots stay adequately watered.

Winterizing Your Mums:

1. Overwintering Indoors:
   To safeguard your mums from the first frost, remove all spent blooms to help conserve the plant's energy. Keep the rest of the foliage intact. Water thoroughly, and then place the potted mum in a cool, dark location indoors, such as the basement or garage, with temperatures ideally between 32°F and 50°F.

   Tip: To prevent root drying during hibernation, lightly water the mum once a week. Be cautious not to overwater; maintain slightly moist soil.

2. Spring Return:
   After the final frost, reintroduce your mums to the outdoors. Continue regular watering. When new foliage starts to appear, trim back the old leaves and stems.

With a little care, you can enjoy your mums for years to come. Happy gardening!
