How Big Do Mums Grow

A: Hardy chrysanthemum plants can grow 1 to 3 feet tall, depending on the cultivar, with a spread sometimes equal to the height. To keep them growing optimally, they should be planted in a full-sun location that receives at least six hours of direct sun per day.

How much space do mums need?

I usually space mums a minimum of 24 inches apart. Remember, these plants are perennials that will increase in size over time. I always start with a row around the perimeter of bed and then stagger plants towards the inside of the perimeter row, and so on towards the center until the bed is full.

Do mums spread out?

Mums steadily spread, but tend to die out in the centers. So every couple of years, lift the clump in spring, discard the old, woody center, divide the remainder into 3-4 plants, and replant.”.

Do mums get bigger each year?

Cut back the stems of the mums to 3 to 4 inches (8 to 10 cm.) above the ground. Leaving a little bit of the stems will ensure that next year you have a full plant, as the new stems will grow from these trimmed stems. If you cut the mums back to the ground, fewer stems will grow next year.

Do mums come back every year?

They will grow back and your plant won’t look dead in the middle.” Many people buy mums in the fall thinking the plants are annuals. But if you buy hardy mums, you can get them to bloom year after year.

Can mums survive the winter in pots?

Mums can survive light frosts and cold fairly easy, but a hard freeze can kill roots in pots permanently. Once potted mums have endured a hard freeze, their chances for surviving winter are slim. Cut mums back to within a few inches of the soil line before bringing indoors.

How long do mums last in pots?

Garden mums may be grown in containers, or planted in beds with existing shrubs and flowers. Flowers generally last about two or three weeks, depending on the outdoor temperatures and how far along the blooming process was when the plants were purchased.

Do mums like sun or shade?

Chrysanthemums are sun-loving plants. Although they technically require only 6 hours of sunlight each day, the more light they receive, the better their growth, bloom and hardiness. Slight shade in hot, summer afternoons is appropriate in warmer gardening zones to prevent scorching.

When should I buy fall mums?

Mid-September is the earliest time you should consider buying mums. However, each year the longer and hotter summers are pushing that date later and later into September, even into the month of October. As a rule, we at Southern Living recommend “buying plants as they start to break bud. You’ll maximize bloom time.

Are garden mums invasive?

A: That sounds like what’s commonly called “wild chrysanthemum” or mugwort. It’s actually a type of invasive artemisia that has scalloped leaves that do look somewhat like garden mums. It is one of the nastier weeds because it’s a perennial with a really deep, vigorous and spreading root system.

Why do mums flop over?

Even in their perennial range, mums fall over when they get tall and leggy, one reason that some gardeners grow them as annuals for the seasonal color their bright flowers add to the landscape. And, routinely dividing your mums is another way to control the size of the clumps.

How do you keep mums compact?

Regular pinching will keep them compact and prevent them from growing too tall; however, plants should not be pinched later than the Fourth of July to assure good bud development and gorgeous blooms before the threat of freezing fall or winter temperatures.

How do I save my potted mums for next year?

Keep mums indoors until one week before the last expected spring frost. At that time, take the pot outdoors to its summer location for two or three hours, then bring it back indoors to its winter location. Each day, bring the pot outdoors and leave it there for an hour or so longer each time.

Can you put potted mums in the ground?

Technically, however, they can be planted in your garden any time before the first frost of fall. This means you can try removing the mums from your pot and planting them in the ground in the fall. Plant them at the same depth as they were in the pot and water them thoroughly after planting.

Are potted mums annuals or perennials?

There are potted florist mums, which look just like garden (hardy) mums and even share the same botanical name (Chrysanthemum x morifolium)—and they’re perennials, but their survival depends on when you get them and where you live. Garden mums, also known as hardy mums, are perennial mums.

What do I do with my mums after they fall?

Shortly after Fall or in late winter, when the mum has finished blooming, ensure you cut the plant’s stem to 6 to 8 inches above ground level. However, if you find the dead stems of winter valuable to wildlife or of interest, you may choose to leave the stems intact until the spring growth develops.
