How Resilient To Cold Are Chrysanthemums?

To winterize chrysanthemums, it is essential to choose the type that can survive in freezing temperatures. Most hardy chrysanthemums can survive temperatures as low as -20 degrees Fahrenheit (-29 degrees Celsius). To ensure the longevity of these beautiful flowers, it is crucial to provide proper winter care.

Chrysanthemums are popular end-of-season flowers due to their bold, beautiful, and sweet scent. They are low-maintenance and hardy plants, making them an excellent choice for gardens. Hardy garden chrysanthemums, or hardy mums, are cultivars developed for winter hardiness and are popular for adding color to the landscape in early fall. To ensure the plants establish roots, plant cold hardy cuttings in the spring after the last frost or 6-8 weeks before the first frost.

In moderate climates, the most popular fall perennial is the garden chrysanthemum, also known as cushion mum. Although most garden mums are hardy to zone 5, it is safe to assume that new plants will require some winter protection, especially its first one.

Frost tolerance varies with species, but most potted mums sold in late summer for fall display are hardy to -0°F (-18°C) if well rooted. Their hardiness range tends to be within USDA Hardiness Zones 5-9, but some can take even colder winters. Potted mums thrive in daytime temperatures between 60°F and 70°F (15°C to 20°C), and most hardy mums continue to bloom as temperatures dip down as low as 20 degrees Fahrenheit.

How cold is too cold for mums?

Potted mums can withstand light frosts but prolonged exposure to freezing temperatures can damage their foliage and reduce their cold tolerance. Protective measures include placing them in a sheltered location near a building or under an overhang, and surrounding them with insulating material like straw or mulch to regulate soil temperature and protect roots. Mulching also helps retain moisture, preventing soil drying out during winter months.

At what temperature should I cover my mum?

To encourage new growth in mums, remove wilted blooms and use mulch to cover the base when temperatures reach 20°F. Maintaining a consistent temperature is crucial for their health, as soil temperature fluctuates from freezing to thawing, damaging roots. Mums bloom throughout the fall, with some species providing blooms from late spring through November. However, 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. Keeping the soil well-drained and consistent in temperature is essential for maintaining the health of your mums.

What is the low temperature for Chrysanthemums?

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.

What is the difference between mums and hardy mums?

Hardy mums are perennial plants that go dormant in winter and return the following year, while florist mums are annual plants that die after a hard freeze. Gillespie’s carries both types in the spring and fall, making them suitable gifts for various occasions, including sympathy expressions. Hardy mums can serve as a reminder of loved ones during their bloom cycle. Gillespie Florists also offers cut flower options featuring mums and fun trim options or plant inserts for various occasions.

What are the best colors for mums?

Fall mums are a great way to add a burst of color to your landscape, with their vibrant hues of orange, purple, gold, and warm white. There are two main types of fall mums: florist and perennial mums. Perennial mums are planted in gardens and bloom in the fall, but are typically too tender for North Dakota’s climate. Florist mums are often found in stores during this time of year. When buying the best mums, it is recommended to choose healthy-looking plants with many buds, as these are at an early stage of their bloom cycle, allowing for longer blooms. Plant care is easy as long as the pot is healthy.

How to winterize mums?

Fall mums, also known as “garden mums” or “hardy mums”, are a popular late-season plant that can be grown in containers or beds. They are low-maintenance, easy to grow, and can be kept in containers or grown in beds. They are drought-resistant and generally free of insects and disease.

To grow and care for fall mums, cut them back to within one inch of the soil and ensure it is moist. Place the pot in a protected area, such as an unheated shed, basement, garage, cold frame, against a building, or under the protective branches of an evergreen tree. If keeping the plant indoors, cover it with mulch or leaves. If keeping the plant in an unheated building, place it on top of newspapers or magazines to help insulate the roots.

Check the plant once a month to see if it needs watering. If dry, water. When the weather turns mild in March, bring the pots outside and plant them in the ground.

Fall mums are typically purchased and planted from late August into September. They prefer full sun, but most cultivars can get by with a half day of direct sunshine. For optimal growth, plant the new mums in fertile, well-drained soil. Young plants should be planted 18-24 inches apart, while mature plants can be planted at any desired spacing.

Are chrysanthemums short day plants?

A short-day plant requires a long period of darkness, forming flowers when day length is less than 12 hours. Examples include chrysanthemums, poinsettias, and Christmas cactus. Exposure to more than 12 hours of light per day prevents bloom formation. Long-day plants require only a short night to flower, such as asters, coneflowers, California poppies, lettuce, spinach, and potatoes. Some plants, like tomatoes, corn, cucumbers, and some strawberries, form flowers regardless of day length. Some plants, like petunias, flower earlier and more profusely with long days. Horticulturists and home gardeners manipulate day and night length to get plants to bloom at times other than naturally.

What temperature do garland chrysanthemums like?

Garland chrysanthemum is an annual herb with a yellow center and yellow or half-yellow/half-white petals. It grows up to 90-120 cm tall and is used as an ornamental plant. It can be grown up to 1500 meters, with 600-2500 mm/year rainfall, and prefers well-drained soil with a pH of 5. 3-7. 3. Its light range is full sun to partial shade. Its day length sensitivity is not significant, and its cultivation requires a temperature range of 7-25 °C.

What are the most cold hardy mums?

It is recommended that early blooming varieties such as Belle O’ The Ball, Cameo, Gold Country, Centerpiece, Peach Centerpiece, and Quarterback be selected in order to maximize the duration of flowering.

Do I need to cover my mum for frost?

To overwinter potted mums, cut them back after the first frost and cover them with 3″ of mulch. Cover the pot with an old sheet and move it into a cool garage. Once the weather warms again in spring, remove the sheet and mulch layers and move the pot outside. If mums are growing in the landscape, cut them down and cover them with 3″-4″ of mulch. Keep them moist throughout the winter and remove the mulch layers once the frost threat has passed. If growing mums in the landscape, divide them every other year to allow them to grow to their full potential.

After the frost threat has passed, dig up clumps, separate plants, and replant them, offering 18″ of space between new transplants. Plant mums in well-prepared garden soil and an area with full to part sun.
