Mums: Fall’s Last Great Color Show
How to enjoy them now and possibly keep them for years.
❧
The garden may be slowing down, but chrysanthemums clearly did not receive the memo. These flowers have an astounding range of colors that include shades of raspberry, rose, blush, apricot, cream/white, and golds ranging from daisy-yellow to bronze. Fall mums are porch pleasers that bring an operatic performance to a season usually involving heavy coats, leaf blowers, and muddy shoes.
Choose Your Color Personality
Deep pink, magenta, and burgundy mums bring the drama. They are the flowers most likely to enter a room before you do.
Soft peach and blush blooms are gentler and work beautifully with grasses, silvery foliage, pumpkins, and weathered wood.
Yellow mums provide instant sunlight when the actual sun has decided to make fewer appearances.
Bronze and gold shades add a regal air and are totally in keeping with a theme based on fall colors.
Mixed displays are cheerful, but try grouping colors rather than scattering every shade everywhere. Even flowers appreciate a little organization.
How to Care for Mums in Containers
Give them bright light. They need at least four hours of sun to stay compact and continue flowering.
Water thoroughly when the surface of the potting mix feels dry and at the beginning of fall, that’s probably every day, if not twice a day. Container mums can go from pleasantly moist to dramatically wilted with surprising speed, especially in warm weather.
Make sure excess water can drain. A decorative pot with no drainage hole is a beautiful little bathtub, not a happy home for a mum.
Remove faded flowers when you like. This tidies the plant and can encourage the display to keep looking fresh, though many mums will continue flowering without constant deadheading.
If the plant is packed tightly in its nursery pot, check it often. Dense roots and autumn breezes can make a small container dry out faster than expected, and with a big ‘crown’ of foliage and blooms it can literally blow off your porch, across the front lawn and down the road.
Repotting from the nursery container into a larger one will give your mums longevity. In a nursery environment, they are cosseted with every need attended to. At your place, that may not happen, and repotting will provide your plant with a buffer on the days when plant care slips to the next day on your to-do list.
Can You Plant Them in the Ground?
Yes – get the compounding floral interest out of your investment! Although many of the mums sold in autumn are not bred for permanent garden beds, they can sometimes live for many years when planted in the ground. Florist and pot mums are frequently selected for compact growth, heavy flowering, and a precise selling-season display rather than outstanding garden-bed performance. That does not mean they are doomed after one season; it simply means their long-term hardiness can be less predictable.
For the best chance of success, plant them while the soil is still workable. Choose a sunny, well-drained site, loosen the roots if they are circling the pot, and plant at the same depth they were growing in the container. Cut the top growth in half so the plant can concentrate on rooting in, and keep an eye on watering while they establish, especially if autumn stays dry.
In growing zones 7 and above, many mums have a reasonable chance of returning, but survival still depends on the cultivar, drainage, winter weather, and how well the plant has rooted before very cold weather arrives. Leave the remaining stems standing over winter for protection, then cut the old growth back in spring when new growth begins. If the plant returns, many gardeners pinch the growing tips in spring or early summer to encourage a fuller shape and more flowers. I don’t bother and have never regretted missing that step.
A Few Sensible Expectations
A plant that returns may not look exactly like the original autumn display. The flowers may be smaller, later, or less densely packed.
Some plants will thrive for years. Others will give you one magnificent encore and then permanently retire. It’s a tiny bit of work that may reward you every year for many years to come.
Many of the gorgeous full displays are actually many plants rather than one plant. If you decide to plant the end-of-season porch pleaser in the ground, check to see if it can be divided and planted in a large group or several different locations.
Save the plant label if you have it. The cultivar name and hardiness information are much more useful than trying to identify a mystery mum next spring.
Avoid planting in soggy soil. Wet feet are a guaranteed mum killer and a bigger problem than winter cold.
Enjoy the Encore
Whether you treat mums as seasonal color and chuck the dried-out leftovers in the bin, or invite them to stay permanently, they earn their place in the autumn garden. Give them sunlight, water, a free-draining location, and a little patience. Some will simply brighten the porch for a few weeks. Others may surprise you by returning next year, ready to put on the same flamboyant show all over again.
