Can Chrysanthemums Be Grown Outdoors?

Chrysanthemums are hardy perennials that thrive in full sun locations in humus-rich, loamy soil with a slightly moist but well-draining pH of 6.5 to 7.0. They can be planted outside from late spring and require regular fertilization. Two varieties that thrive outside are ‘Allouise Salmon’ and ‘Pandion Bronze’.

Chrysanthemums are widely available, straightforward to grow, and flower abundantly outdoors in late summer and autumn. However, it is best to protect them from frost. Late-flowering chrysanthemums should be potted into a loam-based compost and grown in a sunny spot outdoors in summer. They can also be grown under cover, but they don’t mind cold, but not cold and wet.

Chrysanthemums can be kept outdoors (in the ground) through the winter, but in extremely cold areas, overwinter. Early flowering chrysanthemums bloom outdoors in August and September in the open ground and can be planted out in the garden from May.

Fertilizing chrysanthemums regularly during the growing season with a balanced fertilizer like a 10-10-10 formula is essential for healthy growth. Planting chrysanthemums in fertile, well-drained soil in full sunshine all day is recommended. When buying packaged mums in the fall, plant them in the same location as the original ones.

How long do chrysanthemums last?

It is advisable to avoid cultivating plants with faded flowers, as garden mums can be successfully grown in containers or beds in proximity to existing shrubs and flowers. The typical lifespan of flowers is two to three weeks, with the precise duration dependent on external temperature and the blooming process.

How long do chrysanthemums last in garden?

Garden mums can be cultivated in containers or beds in proximity to existing shrubs and flowers. The typical lifespan of flowers is two to three weeks, with the precise duration dependent on external temperature and the plant’s blooming stage.

Is chrysanthemum an indoor or outdoor plant?

Chrysanthemums thrive in indoor temperatures between 10-18℃ and prefer slightly cooler areas to extend their flowering period. They require moist soil and frequent watering. The night’s darkness is symbolized by the first rays of light, signaling our bodies to join the waking world. Chrysanthemums burst with brightness and come in various shapes and sizes, adding a subtle spark of life to any room.

Their variety of colors, affordability, and easy care instructions make them an ideal choice for anyone. Chrysanthemums have long-lasting blooms, making them suitable for indoor enjoyment and garden planting. While enjoying them indoors, follow these guidelines for their care:

1. Water regularly.
2. Avoid direct sunlight, as it can extend the flowering period in cooler areas.
3. Water Chrysanthemums regularly to maintain their health and longevity.

Can mums stay in pots outside?

Florist mums, which come in various bloom forms, are grown in greenhouses and are used indoors. They produce few underground runners, which are needed for cold weather survival. They are often used as short-term bedding plants when the blooms are spent or frost kills them. Potted florist mums are not expected to survive winter outside. Garden mums, on the other hand, can survive cold better and are perennials in Zones 5-9. However, some cultivars are less hardy and can be killed by early spring frost.

Both types of mums make excellent container plants, and care for them by selecting the right plant with more buds than open flowers. This will help them last longer and make the repotting process less traumatic for plants not yet in full bloom.

Can you keep potted mums outside?

Potted mums should be moved outside during Labor Day weekend to prepare for fall gardening and decorating. If the weather is still hot, wait a few weeks and plant them in mid-to-late September. When the weather cools, it’s time to set out the pots. Choose plants with many closed bloom buds and buy “hardy mums” to ensure longevity.

To keep potted mums over winter, plant them in a sunny spot with fertile, well-drained soil with organic matter. Replant them every couple of years, discarding the old center and dividing the remaining plants into three to four plants. Remove wilted blooms to encourage new growth and use mulch to cover the base of the mums when temperatures reach 20°F. This helps maintain an even temperature through insulation.

In summary, potted mums should be moved outside during Labor Day weekend to prepare for fall gardening and decorating. They should be planted in sunny spots with fertile, well-drained soil and replanted every few years.

Are chrysanthemums heat tolerant?

Once established, Hardy chrysanthemums demonstrate tolerance to elevated temperatures and periods of drought. They flourish in soil that is fertile and well-drained, with a pH that is neutral to slightly acidic. They are capable of withstanding low temperatures, with some species demonstrating resilience to temperatures as low as -0°F (-18°C) when well-rooted, while others have been observed to survive temperatures as low as -30°F (-34°C).

Can chrysanthemums be grown in pots?

Chrysanthemums thrive well in pots, especially for space-limited gardeners or those who enjoy container gardening. To grow them, choose a pot at least 30cm in diameter with good drainage holes and consider using clay or ceramic pots for healthier root growth. The optimal planting time is in spring, post the last frost, to allow the plants to establish a robust root system before winter. This will help Chrysanthemums thrive in waterlogged soil and provide ample time for healthy root growth.

How long do potted chrysanthemums last?

Potted mums are best suited for cooler temperatures, as they can last up to eight weeks before frost. To ensure their longevity, it’s recommended to buy them when the temperature is cooler, as the flowers may fade soon. To care for potted mums, follow these simple tips:

1. Choose the best chrysanthemums for your fall containers. Ensure that the plants are not under or overwatered, as this can stress them and affect their performance.

2. Avoid placing the mums in warm conditions, as the flowers may fade soon. Waiting until it’s cooler will help maintain their beauty for up to eight weeks before frost.

Can mums get too much sun?

To ensure the longevity of chrysanthemums, water gently to avoid breaking or saturating the blooms, using a hose or watering can under the blooms or self-watering pots. Keep the plants cool to prevent heat stress and allow them to receive partial shade. Chrysanthemums can be susceptible to leaf spot, powdery mildew, and viruses like mosaic or stunt. Prevention is key, as they should not be crowded or planted in shade, as this can create a breeding ground for disease.

Give them plenty of air and sun, and avoid feeding them to bugs like aphids, caterpillars, leafhoppers, leafminers, and spider mites. Rabbits and deer are generally not interested in chrysanthemums’ fuzzy, fragrant leaves and blooms, preferring blueberry bushes. The ‘Clara Curtis’ is a tough, old-fashioned chrysanthemum flower with pink, daisy-like blooms with golden centers, measuring 2 to 3 inches in diameter.

Where is the best place to plant chrysanthemums?

Chrysanthemum plants are sold as rooted cuttings or small plants in spring. They can be grown at home after frost has passed, in moist but well-drained soil with compost or manure. Single-bloom chrysanthemums need staking and can be pinched out and ‘disbud’. Tender types can be grown as house plants or in the greenhouse for cut flowers. Chrysanthemums can also be grown in pots and brought undercover in autumn for continued flowering. Monty Don believes that chrysanthemums should be grown more, as they are a popular and versatile plant.

Can indoor chrysanthemums be planted outside?

Chrysanthemums are ready to be planted in the garden when their roots have filled the pot, around mid-May. Choose a sunny, sheltered spot with strong winds and well-drained, fertile soil. Push bamboo canes into the ground at 30-45cm intervals and plant one chrysanth next to each cane. Choose from various chrysanthemum varieties, such as Avignon Pink, Bigoudi Red, Pip Salmon, Pip Sunny, Rossano Elizabeth, Spider Bronze, Spiro White, Spiro Yellow, Tarantula Red, Tula Carmella, Tula Improved, Tula Purple, and Tula Zoraya. These varieties should be grown in a greenhouse, polytunnel, or sheltered southerly garden.
