Mums, also known as chrysanthemums, come in various types and sizes.

Some chrysanthemum plants can grow up to 4 feet tall, while most reach a height of 3 feet.

The tallest chrysanthemum varieties are the pompon and spoon types.

Pompon mums have small, round flowers that can be as large as 4 inches in diameter, while spoon mums have semi-double flowers with curved florets resembling spoons.

Hardy chrysanthemums can grow 1 to 3 feet tall, depending on the cultivar, with a spread equal to their height.

To prevent tall and spindly growth, they should be planted in a sunny location with well-drained, slightly moist soil.

Regular pinching back of taller mums, starting when they are about 6 inches tall, will keep them compact.

Pinching should not continue later than the Fourth of July to ensure good bud development and beautiful blooms.

Shorter varieties do not require pinching, but it can be done to delay flowering.

Growing Chrysanthemums In Pots

Chrysanthemums, with their diverse range of sizes and colors, are an ideal choice for growing in pots. Whether you have limited outdoor space or simply prefer to have more control over the growing conditions, pots offer a convenient way to nurture these beautiful flowers.

To successfully grow chrysanthemums in pots, ensure you have a large enough container that provides ample space for root growth. A 12-inch container is generally recommended for most garden mums, allowing their roots to spread comfortably. Additionally, it is crucial to use fertile planting soil that offers good drainage.

To create a rich environment for your potted chrysanthemums, consider adding aged manure or compost to the potting soil. These organic amendments contribute vital nutrients and promote healthy growth. Furthermore, place your potted mums in a sunny location to ensure they receive the necessary sunlight. Fertilizing them weekly will help maintain their vitality and encourage abundant blooms.

Pruning back branch tips in spring and early July is also an essential step in growing chrysanthemums in pots. This practice promotes new growth and aids in bud development. By setting buds and flowers in July, your potted mums will be in full bloom by September, providing a dazzling display of colors and textures.

  • Ensure you have a large enough container for root growth.
  • Use fertile planting soil with good drainage.
  • Consider adding aged manure or compost to the soil for vital nutrients.

Pruning And Bud Development For Chrysanthemums

Pruning is crucial in the development of chrysanthemums. Selectively cutting back branch tips stimulates new growth and encourages an abundance of buds. Here are some important considerations for pruning chrysanthemums:

  1. Timing is key: Prune back branch tips in spring and early July. This allows for optimal bud development and prevents interference with blooming before freezing temperatures arrive.
  2. Regular pruning: Every two to three weeks during the specified period will help keep chrysanthemums compact and prevent excessive height.
  3. Healthier growth pattern: A well-pruned chrysanthemum plant not only looks visually appealing but also promotes a healthier growth pattern. By removing dead or diseased parts, the plant can channel its energy into producing more buds and achieving an overall balanced and vibrant appearance.

Remember, proper pruning techniques and timing are essential for maintaining healthy and beautiful chrysanthemums.

Preventing Mums From Growing Tall And Spindly

While there are various factors that contribute to the size and shape of chrysanthemums, there are ways to prevent them from growing tall and spindly. By providing the right growing conditions and implementing proper care practices, you can maintain compact and healthy plants.

One important aspect is selecting the right location for planting. Chrysanthemums should be placed in a full-sun position that receives at least six hours of direct sunlight per day. If planted in shady areas, they may stretch and become straggly in search of more sunlight.

In addition to sun exposure, the soil should be well-drained and slightly moist. Proper watering techniques, such as watering at the base of the plant and avoiding overhead watering, will further contribute to the plant’s overall health and prevent leggy growth.

For tall hardy mums, it is recommended to start pinching them back when they reach about 6 inches in height, which is typically in late spring. This practice should be continued every two to three weeks. Regular pinching will encourage branching and keep the plants compact. However, it is important not to pinch the plants after the Fourth of July to ensure good bud development and stunning blooms before the arrival of freezing temperatures.

It is worth mentioning that shorter varieties of mums do not necessarily require pinching to maintain their compact form. However, pinching can be done if one wishes to delay the flowering process.

Chrysanthemums exhibit a wide range of sizes, from towering pompon and spoon varieties to more compact and versatile options.

  • Whether grown in pots or directly in the garden, chrysanthemums add a touch of elegance and splendor to any landscape or floral arrangement.

  • Proper location and sun exposure is crucial for preventing leggy growth.

  • It is important to provide well-drained and slightly moist soil to promote healthy plant growth.

  • Starting the pinching back process at about 6 inches in height will help maintain compact plants.

  • It is important not to pinch the plants after the Fourth of July for optimum bud development.

  • Shorter varieties of mums may not require pinching, but it can be done to delay flowering.

Frequently Asked Questions

Do mums come in different sizes?

Yes, mums do come in different sizes. They range from petite compact varieties, perfect for containers or small spaces, to tall and vibrant ones that can make a statement in a garden bed. Whether you’re looking for charming buttons of blooms or voluminous clusters, there is a size of mum to suit every gardener’s preference. The wide range of sizes allows for creativity in landscaping and ensures that there is a mum for every space, no matter how big or small.

Why are my mums so big?

The reason why your mums are growing so big is due to their natural growth pattern. When left to grow without intervention, garden mums tend to become tall and leggy by summer. This growth can cause them to produce flowers prematurely, which is not desirable. To maintain smaller and more compact mums, it is important to properly manage their growth through pruning and controlling the flowering process.

Will mums multiply?

Yes, mums can multiply through the process of division and cuttings. During early spring, when new growth starts to emerge, gardeners can dig up the entire plant and divide it into separate sections using a sharp knife. This method allows each divided clump to grow independently, resulting in multiple mums. Additionally, mums can also be propagated through cuttings, where a small portion of the plant is cut and replanted to grow into a new plant. With these methods, mums have the ability to multiply and create a beautiful display of colorful flowers.

Do mums spread as they grow?

As mums grow, they have a tendency to steadily spread outwards but often die out in the center. This natural process calls for periodic maintenance. Therefore, it is recommended to lift the clump of mums in the spring, removing the old and woody center, and dividing the remaining plant into three to four smaller ones. By replanting these divisions, you can ensure the healthy growth and longevity of your mums. Additionally, pruning wilted blooms is crucial as it stimulates new growth, leading to a more vibrant and flourishing display.
