Fall Garden Mums | Hardy Mums

As our summer draws to a close and cooler temperatures begin to prevail, we know the growing season is nearing its end. But is it really the end... or time for a new beginning?
We've all heard the saying "Fall is for Planting".

This months topic... Fall Garden Mums

A very popular plant for late season color is Fall mums, sometimes called "Garden mums" or "Hardy mums". Fall garden mums were once known as Chrysanthemums but taxonomists have recently changed their botanical name to Dendranthema x grandiflora. Fall garden mums are available in a wide selection of colors, flower types... shapes and sizes. Fall garden mums are a low maintenance easy to grow plant that can be kept in containers or grown in beds. They are drought resistant and generally free of insect and disease pests.

How to Grow and Care for Fall Garden Mums

Planting
Most Fall mums are purchased and planted from late August into September. Fall mums prefer to be planted in an area that receives full sun, but most cultivars can get by with a half day of direct sunshine. For ultimate growth, plant your new fall garden mums in fertile well drained soil. Poorly drained soil is the leading cause of winter mortality. Young plants... that is those in small containers should be planted 18" to 24" apart. Mature plants can be planted at any desired spacing providing they are planted no closer than just touching its neighbor. Fall mums in above ground containers need to be planted in a flower bed before the first hard frost!

Watering
Fall garden mums should never be allowed to wilt... especially newly transplanted plants. Check your fall garden mums every couple of days for watering until you become familiar with their needs, particularly during dry spells. Be sure to thoroughly water-in your new transplants.

Fertilizing
Newly planted fall garden mums will not require any fertilizer their first season. During the following growing season begin feeding your fall garden mums as new growth emerges, with the plant food of your choice. Feed your plants monthly until August.

Over-wintering... getting them to come back again
Most fall mums are winter hardy in Colorado. One of the most important tips in over wintering fall garden mums is to keep the soil moist as winter approaches. If you're the tidy type... after several hard frosts have blackened the plants, cut them back to near soil level. If not, just leave the plants until the next growing season and cut them back then.

Mulching your fall garden mums to a depth of 3" - 4" after the soil has frozen will help to ensure their return the following spring. The purpose of mulching your fall mums is to keep the soil frozen.

Re-growing... Fall Garden Mums the following spring
Once your fall garden mums start re-growing... remove the old stems if you haven't done so previously. This is the time to start feeding your fall garden mums with your favorite plant food every month until August.

To encourage branching and compact bushy growth, its important to pinch your fall garden mums in early spring. Once your plants have reached 4" - 6" remove about 1" to 2" of new growth on every shoot. After the plants have grown 3" to 5" shoots from the first pinching... its time to pinch again. Stop pinching your plants around mid July. This may seem like a drastic measure... but come fall you'll be rewarded with compact bushy plants that are robust with flowers.

Propagating... giving new life to old plants
Your fall garden mums can be divided every other year in early spring. This helps maintain their vigor. To divide your plants simply take a sharp shovel and press it through the center of the plant and down into the soil. Dig out one of the halves and relocate it to a sunny area. Be sure to thoroughly water-in the new transplant. If you wish, the halves could be divided into quarters.

That's it. As you can see fall garden mums are very easy to grow. They'll provide you with constant color until the first hard freeze.
