Growing and caring for mum plants can be tricky if done improperly. Their growth requirements depend on where they are grown. Most growers often wonder: are mums indoor or outdoor plants?
Mums are generally outdoor plants where they can live year-round. For optimal results, use a 5-to-6-inch pot and keep mum plants well watered with temperatures close to 60 degrees Fahrenheit. When new sprouts appear, move them to full sun and give them plenty of water (Source: University of Missouri)
Mums are classic houseplants that are usually brought as a present at Christmas, Easter, or Mothering Sunday. In some parts of the world, people gift mums as a symbol of motherhood, for instance, shortly after a woman gives birth.

Are Mums Indoor Or Outdoor Plants?
Mums thrive outdoors. It is recommended to keep mum plants outdoors as long as possible in the fall. When light frost threatens, cover your plants, lift the pots, and bring them indoors. During cold, freezing temperatures, you can bring mum plants indoors.
I suggest you place your plants in a sunny south window with temperatures around 60 degrees Fahrenheit at night and between 70 to 75 degrees Fahrenheit during Day time.
In addition, hardy garden mums thrive in pots and are suitable for outdoor planting. Put them out in a sunny, well-drained spot when the ground is warm in spring.
How Do You Know If Your Mums Are Perennial Or Annual?
The annual variety is Chrysanthemum multicaule, and the perennial, fall-flowering form is Chrysanthemum x morifolium. If you can’t identify your plant, remember that the annual mums have thinner, strappy leaves that are not as toothed as the perennials, which are wide and a little notched.
Garden mums, also referred to as hardy mums, are perennial mums and are easier to find for sale online. And most mums sold in garden centers and nurseries are annuals, especially in growing zones 1 to 4.
Hardy chrysanthemums are generally easy-to-grow perennials; unlike other chrysanthemums grown as annuals, perennials mums return year after year, even in colder climates.
Mums Growth Requirements
Mums are perennials, hardy in U.S. Department of Agriculture (USDA) plant hardiness zones 5 through 10, and they grow 6 to 24 inches (15.24 to 60.96 cm) tall and wide.
As houseplants, mums are loved for their ability to purify the air of pollutants. You successfully grow mums and extend their lifespan by learning mum’s growth requirements.

Caring For Mums
Whether you are getting your mums inside your home or outdoors, if you want their blooms to last longer, choose ones where the flowers haven’t opened.
Tips For Growing And Caring For Mums:
- It is best to plant mums in early spring in full sun with moist, rich, well-drained soil.
- When planting mums in the fall, ensure you remove all the flowers to encourage root growth and cover them with thick mulch.
- Good soil drainage is essential for overwintering roots.
- Without sufficient light, mums might survive but thin out; their stems will become long and floppy, affecting their appearance.
- To encourage branching and flower bud production, pinch the stems or shear the plant as soon as the buds appear in the spring.
- You might need to prune during summer if the plant becomes leggy, but ensure to leave the stems on the plant to keep the crown protected over the winter.
- You use stem cuttings to propagate the plant about once a year.
- You can also use division in the spring to avoid dieback in the center of your mum plant.
- Check each day to ensure that the soil is moist. Do not let the plant wilt, and avoid keeping the pot sitting in water.
