In Warm Climates, Do Chrysanthemums Grow Year-Round?

Chrysanthemums, also known as mums, are perennial plants that can be kept outdoors in the ground through the winter. They prefer slightly acidic to neutral soil with a pH between 6.5 and 7.0. They can be bought from garden centers or nurseries year-round.

Chrysanthemums can tolerate light shade but can become leggy if they have to stretch for light. In temperate climates, plant out in spring to ensure roots are well-established before cold winter temperatures. In warm climates, plants often appreciate some afternoon shade. To avoid confusion, plant them near nighttime.

Chrysanthemums grow back each year if planted correctly. To ensure healthy growth, learn how to grow chrysanthemums from seeds or transplants, and choose from different types, colors, shapes, and sizes of these fall-blooming perennials. They can be grown in borders and containers, flowering from September to November.

Chrysanthemums are easy to grow in the garden, but some are hardy only in mild climates and freeze out when planted beyond their zone of winter tolerance. For a reliable perennial chrysanthemum, choose hardy garden varieties that can be left in the ground all year round.

Chrysanthemums can be warm-season annuals or perennials that grow year-round in most climates. They can be sold in the spring as cuttings, in spring and fall as packaged plants, and year-round as potted plants. Plants should be in full sunshine all day.

Do chrysanthemums come every year?

Chrysanthemums are hardy perennials that go dormant in winter and re-sprout in spring. They bring fresh vibrancy to borders and containers during late summer and autumn, making colorful, long-lasting cut flowers. They grow in borders and containers, blooming from September to November. Plant outside from late spring, preferring sun and fertile, well-drained soil. Winter protection may be needed. New plants can be made by taking cuttings. It is recommended to read the instruction labels on your plants.

Are chrysanthemums in winter?

The flowers of the genus Mum typically bloom in the autumnal season, preceding the onset of winter and the subsequent freezing of the ground. This phenomenon results in the display of vibrant colors on the foliage of trees and other plants. Furthermore, they can re-emerge in spring, thereby providing color to bouquets. However, for them to survive, they must endure the winter. To guarantee a spring resurgence, it is essential to select an appropriate variety with robust roots, as not every variety possesses these attributes. Hardy mums have developed deep roots, which make them more resilient and able to withstand winter freezes.

What is the season for chrysanthemums?

Chrysanthemums bloom naturally from mid-August to mid-January and are divided into early flowers (mid-August to mid-September) that can be grown in the garden, and late flowers (mid-October onwards) that are grown in pots for easier propagation in a greenhouse. Early flowering Chrysanthemums bloom outdoors in August and September and can be planted in the garden from April. Before planting, apply Chrysanthemum plant food or another general fertilizer, plant firmly about 60cm/2in apart, and feed every two to three weeks until buds start to form.

Most cultivars can be stopped around the 1st week of May or after this date, when they are about 15cm/6in tall. If premature buds have formed, cut them back hard at least half their height to encourage new shoots to grow from lower down without buds. For blooms, one bud should be allowed to develop on the top of each side shoot, while other buds should be removed as they appear.

Late flowering Chrysanthemums are grown in pots outside until frost is likely, then moved into the greenhouse to flower in November and December. On arrival, they should be placed in 13cm/5in pots in early May and in early June into their final pots, either 20cm/8in or 23cm/9in, using a cane suitable for the variety’s final height. If the plant is ready to pot, turn the pot upside down and tap it out, ensuring the root covers the outside of the soil.

How can you tell if a Chrysanthemum is annual or perennial?

Perennial chrysanthemums, native to China, have broad, deeply toothed leaves and grow to 1 to 3 feet tall and wide. They provide a second bloom in spring in frost-free zones. Plant mums in well-draining soil as early as possible, but not at the garden center. If temperatures dip below freezing within six to eight weeks of planting, enjoy the show until the plants go dormant and store them in an unheated garage or cellar over winter.

Water them occasionally, and plant them in spring after the danger of frost has passed. Consider using them alongside sedums, asters, and goldenrods for a colorful seasonal display in your garden bed.

Are mums all season?

Mums bloom throughout the fall, with some species providing blooms from late spring through the fall. Some mums may be fooled by cool weather and short days into blooming in spring, so it’s important to cut them back to ensure they bloom again in the fall. Perennial mums can bloom yearly, and potted harsh varieties can withstand winter months. To preserve the plant, move it indoors in a cool and frost-free environment like a garage.

Pinching back mums is a trick used by savvy gardeners to encourage a bushier, more floriferous plant in the fall. Pinching or pruning the tip of every stem in spring or early summer, removing any buds that have started to form, can be repeated if stopped in July.

What temperature can chrysanthemums tolerate?

Chrysanthemums are tolerant of USDA hardiness zones 5 to 9, with some varieties able to tolerate lower temperatures. The optimal temperature for indoor or garden growth is between 62 and 72 degrees Fahrenheit. Mums thrive in humid conditions between 70 and 90 degrees Fahrenheit, making the South prime territory for this plant.

Fertilizing and pruning are essential for chrysanthemums. Cut stems at three to four inches above the ground, leaving a little to ensure full plant next year. Once the ground has frozen, add mulch, straw, or leaves to keep the plant insulated. Mulching prevents soil from changing from warming to freezing and back, confusing the plant about whether to stay dormant or begin new growth.

In spring, watch for new foliage, fertilize with organic fertilizer, and pinch every two to four weeks to ensure sturdy plants come fall.

Do chrysanthemums like heat?

To ensure the longevity of blooms, it is recommended that mums be kept in cool conditions and receive partial shade when temperatures exceed 75 degrees Fahrenheit. Excessive exposure to heat and sunlight can result in a reduction in the duration of the blooming cycle.

Do chrysanthemums need full sun?

Chrysanthemums flourish in soil with good drainage and full sunlight. For optimal growth and flowering, they require six or more hours of sunlight per day during the summer months. Plants that receive less light tend to exhibit stunted growth and produce fewer flowers.

Do chrysanthemums like sun or shade?

Chrysanthemums flourish in soil with good drainage and full sunlight, requiring a minimum of six hours of sunlight per day during the summer months. Plants that receive insufficient light will exhibit stunted growth, reduced vigor, and a diminished capacity to produce flowers.

Are chrysanthemums hard to keep alive?

Chrysanthemums, also known as mums, are easy to grow perennials that bloom in the fall, providing a showstopper in gardens. With hundreds of varieties, they offer various height, color, flower size, and time of bloom options. Choose one or two colors for maximum effect or arrange a gradual transition of related colors. For a yard with green foliage, choose bright pinks, lavenders, whites, or reds. Mums can be started as seeds or purchased at garden centers in various sizes. They grow best in full sunshine and receive ample food and moisture. They can be started as seeds or purchased in gallon-size containers.

Will mums survive winter?

It is not uncommon for fall-planted garden mums to experience difficulties in surviving the winter season, even when provided with adequate winter protection. It is advisable to consider them as provisional additions to the landscape. In Iowa, spring-planted mums have the advantage of a longer growing season, during which they can establish themselves and are more likely to survive the winter than those planted in autumn. Spring-planted mums demonstrate greater resilience and are more commonly found in Iowa.
