How To Care For Chrysanthemums?

If you’re looking for an easy-to-care-for plant that will add a splash of color to your garden, chrysanthemums are a great choice!

These plants are a member of the Asteraceae family and come in various colors, including yellow, orange, red, white, and pink.

In this blog post, we’ll show you how to care for chrysanthemums so you can enjoy their vibrant blooms all season long!


Chrysanthemums require regular watering, particularly when in full bloom. The soil must be kept moist but not saturated. 

It is important not to overwater, as this can cause root rot. If the leaves begin to wilt, the plant requires additional water.


Chrysanthemums are robust and can grow on their own if necessary, but they require light and frequent feeding with a balanced fertilizer throughout the growing season.

You can also use compost or manure to fertilize your plants.


Chrysanthemums need at least 5-6 hours of full sun per day. They can tolerate some partial shade but will not bloom as well in areas with less light.


Chrysanthemums prefer cooler temperatures and will not bloom well in hot weather. They can tolerate some frost, but their leaves may be damaged if the temperature dips below freezing.


Chrysanthemums need to stay dry to avoid mildew. They also need good air circulation, water drainage, and morning sun to dry the dew. Make sure not to plant them in low-lying, wet, compacted, or boxed-in areas with little air circulation. 

Chrysanthemum blooming occurs in response to shorter days and cooler temperatures in fall, so make sure to plant them in a location where they will not be disturbed by construction or other activities.


Chrysanthemums can be lightly pruned throughout the growing season to encourage bushier growth. The best time to prune is in late spring or early summer before the plants start to bloom. Cut back the stems by 1/3 to 1/2 their length. Pinching the tips of the stems will also encourage bushier growth.

In late summer or early fall, after the flowers have faded, you can cut the plants back by 1/3 to 1/2 their height to encourage fuller growth the following year.


Aphids, mealybugs, and spider mites are typical chrysanthemum pests. These pests can result in stunted development and deformed leaves. Additionally, they can transmit diseases to plants.


Chrysanthemums are susceptible to several diseases, including powdery mildew, rust, and leaf spot. These diseases can cause the leaves to be yellow and drop off the plant.

To prevent diseases, make sure to water the plants at the base rather than from above. Avoid getting water on the foliage, as this can promote fungal growth. You should also remove any diseased leaves from the plant.

Pinching out

When young plants reach approximately 8 inches in height in early summer, pinch off the main growing point to promote branching. Additionally, you can pinch off the tips of side shoots as they grow until midsummer. This will aid in the development of bushier plants that produce more flowers.

To do this, nip the shoot tip with your fingers or scissors and back to the next set of leaves.

Stopping is often done in commercial chrysanthemum nurseries to create compact plants that can be quickly grown and sold.


After planting, apply a thick layer of mulch to the soil surface. This will help to retain soil moisture and prevent weed germination. Utilize well-rotted manure or garden compost to maintain plant health throughout the winter.


Disbudding is a technique used by specialists to make huge blooms or clusters of flowers. This is done on ‘spray’ chrysanthemums, which produce clusters of flowers. If you remove the large central flower bud, you will get a more uniform display of evenly sized blooms.

On single-flowered chrysanthemums, disbudding will make the one remaining flower larger.

Use your thumb and forefinger to disbud to snap off the extra buds. Do this when they are small, about the size of a pea. You should be able to see where the bud joins the stem – you want to break this connection.

Pinching back

Pinching back is a technique used to encourage bushier growth. It is done by pinching off the tips of the stems when they are about 6 inches tall. This will cause the plant to branch out and become fuller. Do this every few weeks during the growing season.


Many hardy chrysanthemums can survive temperatures as low as -5˚C (23˚F). However, in much of the UK, temperatures can drop below this. So if you want to be safe, you can lift and store your plants over winter in light, frost-free conditions, such as a frost-free garage or shed.

When the flowers have finished blooming, cut the stem down to about 20 cm (8 in) tall. This will make a stool. Lift the plant and shake off the soil from the roots. Cut off any green shoots and leaves, leaving you with bare stems. Label each plant if you have different types, then stand the plants in a tray or box filled with just enough sand to cover the roots—store in a cool, dark place over winter and water sparingly.

In early spring, around March, start to check your plants. If they show signs of new growth, it is time to plant them. Water well and give them a liquid feed to help them get going. Gradually acclimatize them to outside conditions over about two weeks before planting them into their final positions.

You can store your plants in a cold but frost-free location, such as a cool greenhouse or conservatory. You can also keep them in a garage. Just make sure the compost is moist throughout the winter. If you need to move plants, you can do so by putting them in a conservatory. You can also overwinter plants in pots outside if you provide some extra protection.

If you have any chrysanthemums that are not hardy, you will need to bring them inside for the winter. Please keep them in a cool, light room and water sparingly. They may not flower the following year, but they should survive.

when to prune chrysanthemums?

When plants reach a height of six inches, pinch off the top to make them bushier and produce more flowers. When they are one foot tall, pinch them once more.

Some gardeners prune their plants every few weeks until July to promote heavy fall flowering. The last pinching should occur approximately 100 days before blooming.

Allow the blooms to remain on the plant until they are fully open and beginning to fade if you cultivate the plants for dried flowers.

When in full bloom, tall varieties of chrysanthemums may require staking to prevent them from toppling over. Use metal or wooden stakes at least 3 feet in height. Drive the stakes into the ground approximately 6 inches from the plant, and then tie the plant to the stake using soft twine or cloth strips. When tying the stem to the stake, be careful not to damage it.


Should Chrysanthemums Be Pruned?

Don’t worry about how to prune chrysanthemums. Mums aren’t “pruned” but are instead pinched throughout the growing season. This helps the plant branch out, become fuller, and offer more blooms. When your plant reaches 6 inches tall in the spring, pinch off 1 inch of each shoot.

If you want your plant to bloom for a longer time, cut off the blooms throughout the fall. Once the plant dies in the winter, could you not cut it back? Research shows that if the plant dies back naturally over winter, it will be stronger when you clean it up in the spring.

Some gardeners cut mums back to about 4″ tall after they have bloomed. You don’t have to do this, but the branches can help hold mulch in place. Chrysanthemums are beautiful both up close and when grouped in different colors.

When Should I Divide My Mums?

You should divide your mums every 3 to 4 years to keep them healthy. This should be done in the spring before they start to bloom. To divide them, dig up the entire plant and carefully separate it into smaller pieces, making sure each piece has some roots attached. Plant the divisions in new locations, and water them well.

Does Spacing Matter?

Planting mums together might be tempting, but it is not a good idea. Spring mums do not look good in a garden next to more giant fall mums.

Keep in mind that most correctly planted mums will grow up to 3 feet tall and wide by the fall. Your flower bed may look a little bare when you.

How long will chrysanthemums last?

The lifespan of the chrysanthemum is only three to four years. However, it could last longer than that, but it will get more susceptible to winter damage as time goes on.

How do you keep a chrysanthemum alive?

It is essential to water indoor mum plants regularly. When you water them, do it from under the leaves. This will help prevent fungal issues. If you want, you can also deadhead the plant to make it look its best. Ensure the chrysanthemum plants have good air circulation and avoid high humidity levels. These are the best ways to keep a chrysanthemum alive.

When should I cut back my chrysanthemums?

After the blooming period is over, you can cut back your chrysanthemums. This will encourage new growth. You can also deadhead the plant to make it look its best.

I hope that this has helped you learn a little bit more about chrysanthemums. These are beautiful flowers that make great additions to any garden. With proper care, they will bloom for years to come.

Do chrysanthemums grow back every year?

Chrysanthemums are plants that grow back every year. They stay alive during the winter by going dormant and returning to life in the spring.

Where do chrysanthemums grow best?

Chrysanthemums are adaptable to soil types, but they flourish in organic soils. Mums want plenty of sunshine in the landscape as well. Chrysanthemums thrive in the shade but will get leggy when seeking light.

Do chrysanthemums like sun or shade?

Chrysanthemums need sunlight to grow. They need at least 6 hours of sunlight every day, but the more light they get, the better they will grow and bloom. If it is hot outside, you can put them in a spot that gets shade, so they don’t get too hot and scorch.

How do you save chrysanthemums for next year?

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

How many times do mums bloom?

Mums usually bloom continuously for four to eight weeks. You can help them bloom longer by pinching them back. It would help if you started by pinching them back when the plant is 6 to 8 inches tall, then do it again when it reaches 1 foot in height.
