How To Grow and Care for Mums?


In the world of Chrysanthemums, nature paints a masterpiece with its breathtaking blooms and vibrant colors.

These enchanting flowers have been cherished for centuries as symbols of beauty and joy.

They have captured the hearts of flower enthusiasts with their graceful petals, vibrant hues, and the power to transform any space into a haven of tranquility and natural splendor.

Whether you’re a seasoned horticulturist seeking new horizons or a beginner eager to embark on a journey of green-thumb prowess, in this guide, we invite you to dive into the world of mums as we discover their care and growth patterns.

What Are Mums?

Chrysanthemums, also known as mums, are a genus of about 40 flowering plants that belong to the Asteraceae family.

They are native to northeastern Europe and Asia, with their origins traced back to China and Japan.

They can vary in height from dwarf varieties that reach only a few inches to tall cultivars that can grow up to four feet or more.

The foliage consists of profoundly lobed or toothed, typically dark green leaves.

The flowers of chrysanthemums come in a vast range of colors, including yellow, white, orange, red, pink, lavender, and bronze.

Some cultivars even exhibit bi-colored or multi-colored petals and can vary in shape, from the classic daisy-like form with a prominent central disk surrounded by petals to spider-like petals, quilled petals, and more.

Here’s how to grow and care for mums.

Soil Preparation

Chrysanthemums thrive in moist, well-drained soil with a pH range of 6.5 to 7.5.

So you must prepare the soil by incorporating organic matter, such as compost or well-rotted manure, to improve its fertility and drainage.


Plant your chrysanthemums in spring or early summer when the soil has warmed up.

Dig a hole slightly larger than the root ball and place the plant in the hole, ensuring the crown is level with the soil surface.

Space the plants according to their mature size to allow for proper air circulation and prevent diseases.


Chrysanthemums are sun-loving plants that require at least 6 hours of direct sunlight per day for optimal growth and abundant blooms.

So you must ensure they are planted in a location that receives adequate sunlight.


Throughout the growing season, keep the soil evenly moist but not soggy.

Water deeply but infrequently, concentrating at the base of the plants and avoiding overhead watering, which can promote root rot and other diseases.

Reduce watering as the flowering season comes to an end.


Apply a balanced slow-release or liquid fertilizer with a 5-10-5 formulation every 4 to 6 weeks during the growing season to promote healthy blooms.

Ensure you follow the instructions on the fertilizer package for the appropriate application rates.


Cut back the growing tips of young chrysanthemum plants when they reach about 6 inches (15 cm) in height to encourage branching and lead to bushier plants with more flowers.

Prune off dead flowers to encourage continuous blooming and maintain a neat appearance.

When Do Mums bloom?


Chrysanthemums bloom at different times depending on the specific variety and the growing conditions.

Generally, they bloom in fall, which makes them a popular choice for adding color to autumn gardens.

However, bloom times can vary based on your specific climate and growing conditions.

Factors such as temperature, sunlight exposure, and regional climate patterns can influence the exact timing of chrysanthemum blooms.

Early Bloomers

Some chrysanthemum varieties bloom earlier in the season, typically in late summer or early fall, around August to September.

These early bloomers include ‘Single Korean,’ ‘Sheffield Pink,’ and ‘Clara Curtis.’

Mid-season Bloomers

Most chrysanthemum varieties fall into this category and bloom from late summer to mid-fall, usually from September to October.

These cultivars are often called “garden mums” and are available in various colors and flower forms.

Japan’s National Flower

In Japan, chrysanthemums are the national flower and symbolize longevity, rejuvenation, and changing seasons, characterized by festivals, such as the “Festival of Happiness” or “Chrysanthemum Festival.”

Late Bloomers

Some chrysanthemums can be bred to bloom later in the fall, extending the flowering season.

These late-blooming varieties can start blooming in October and continue until frost.

Possible Problems

Here are some potential problems you might face when growing mums.


Chrysanthemums are susceptible to pests such as aphids, spider mites, thrips, and leafhoppers.

These pests can cause damage by feeding on plant tissues or spreading diseases.

You can use insecticidal soaps, horticultural oil, rubbing alcohol, neem oil, or natural predators to control the pests.


Diseases such as powdery mildew, gray mold (Botrytis blight), leaf spot, and root rot are common in chrysanthemums.

These diseases can cause leaf discoloration, wilting, defoliation, or even plant death.

Good cultural practices such as proper spacing, avoiding overhead watering, and removing infected plant parts can help prevent and manage diseases.

Bud Blast

Bud blast is a condition where flower buds fail to open or wither prematurely.

This can occur due to environmental stress, fungal infections, or inadequate care practices.

Ensure your chrysanthemums receive proper watering, adequate sunlight, and a suitable growing environment to prevent bud blasts.

Nutrient Deficiencies

Common chrysanthemum nutrient deficiencies include nitrogen, phosphorus, and potassium.

Yellowing leaves, weak stems, or poor flowering can indicate these deficiencies.

Fertilize your chrysanthemums with a balanced fertilizer formulated for flowering plants to address nutrient deficiencies.


Growing and caring for chrysanthemums can be a rewarding experience, allowing you to witness the vibrant beauty of these enchanting flowers.

All you need do is provide proper conditions, and you can create a flourishing garden filled with the captivating allure of chrysanthemums.
