Chrysanthemums, commonly known as mums, are one of the most popular flowers in the world. They are cherished for their vibrant colors, variety of shapes, and ability to bloom in late summer and fall when many other flowers have faded. For gardeners and flower enthusiasts, having a lush display of chrysanthemum blooms is a delightful sight. If you want to know how to get more flowers in your chrysanthemums, this comprehensive guide will help you understand the essential steps and techniques needed to maximize bloom production and enjoy a bountiful floral display.
Understanding Chrysanthemums
Before diving into the techniques for increasing flower production, it’s essential to understand the basics of chrysanthemums. These flowers belong to the Asteraceae family and come in various forms, including daisy-like, pompon, spider, and cushion types. They are perennial plants, meaning they can grow back year after year if cared for properly. Chrysanthemums thrive in well-draining soil with plenty of sunlight and are generally easy to grow, making them a favorite among gardeners.
Selecting the Right Variety
Choosing the right chrysanthemum variety is the first step to ensuring abundant blooms. Different varieties have unique growth habits, bloom times, and flower sizes. Some chrysanthemums are bred specifically for their large, showy flowers, while others are known for their smaller, but more numerous, blooms. When selecting a variety, consider the following:
Bloom Size and Type: If you want more flowers, choose varieties that produce multiple blooms per stem, such as cushion or pompon chrysanthemums.
Bloom Time: Early, mid, and late-blooming varieties are available. Planting a mix of these can extend your flowering season.
Climate Compatibility: Some varieties are better suited to certain climates. Check with your local garden center or extension service for recommendations on varieties that perform well in your area.
Soil Preparation
Healthy soil is crucial for growing vibrant, flowering chrysanthemums. They prefer well-draining, fertile soil with a slightly acidic to neutral pH (6.0 to 7.0). Here’s how to prepare your soil to encourage more blooms:
Test Your Soil: Conduct a soil test to determine its pH and nutrient levels. You can purchase a soil testing kit or send a sample to a local extension office.
Amend the Soil: Based on your soil test results, amend the soil to correct pH and nutrient imbalances. Adding organic matter such as compost or well-rotted manure can improve soil structure and fertility, providing a rich growing medium for your chrysanthemums.
Ensure Good Drainage: Chrysanthemums do not like wet feet. If your soil is heavy clay or tends to retain water, consider planting chrysanthemums in raised beds or adding sand or perlite to improve drainage.
Planting Techniques
Proper planting is essential for ensuring that your chrysanthemums produce a profusion of flowers. Here are some key planting tips:
Timing: Plant chrysanthemums in the spring after the danger of frost has passed. This gives them plenty of time to establish their root systems before blooming in the fall.
Spacing: Space plants 18 to 24 inches apart to allow for adequate air circulation and room for growth. Overcrowding can lead to poor air circulation, which increases the risk of disease and reduces flower production.
Depth: Plant chrysanthemums at the same depth they were growing in their nursery pots. Planting too deeply can smother the roots and reduce blooming.
Watering Practices
Consistent watering is crucial for chrysanthemum growth and flower production. Here’s how to water your plants for optimal results:
Water Regularly: Chrysanthemums need about 1 inch of water per week, either from rainfall or irrigation. Water them deeply and regularly, especially during dry spells. Deep watering encourages the roots to grow deeper into the soil, which helps the plant withstand drought and promotes more blooms.
Avoid Overwatering: While chrysanthemums need consistent moisture, overwatering can lead to root rot and other fungal diseases that reduce flower production. Always allow the soil to dry slightly between watering sessions.
Fertilization
Proper fertilization is key to getting more flowers from your chrysanthemums. They are heavy feeders, especially when they are preparing to bloom. Here’s how to fertilize effectively:
Balanced Fertilizer: Use a balanced fertilizer, such as a 10-10-10 or 20-20-20 formula, to provide essential nutrients. Apply this fertilizer in the spring when new growth begins.
Bloom Booster: As the blooming season approaches, switch to a fertilizer high in phosphorus, such as a 5-10-5 formula, to encourage flower development.
Frequency: Fertilize every 4-6 weeks during the growing season, but reduce fertilization once the plants start to bloom to avoid excessive foliage growth at the expense of flowers.
Pruning and Pinching
Pruning and pinching are essential techniques for encouraging more blooms in chrysanthemums. These practices promote bushier growth and more flower buds.
Pinching: Start pinching back your chrysanthemums in early summer when they are about 6 inches tall. Pinch off the top 1-2 inches of each stem. This will encourage the plant to branch out and produce more stems, leading to more flowers. Continue pinching every 2-3 weeks until mid-July, depending on your climate.
Deadheading: Remove spent flowers regularly throughout the blooming season. Deadheading prevents the plant from putting energy into seed production and encourages it to produce more flowers.
Cutting Back: After the first hard frost, cut back the plants to about 6 inches above the ground. This helps prepare them for winter and encourages healthy growth in the spring.
Mulching
Mulching helps retain soil moisture, suppress weeds, and regulate soil temperature, all of which contribute to healthy chrysanthemum growth and increased flower production.
Organic Mulch: Apply a 2-3 inch layer of organic mulch, such as shredded bark, straw, or pine needles, around the base of your chrysanthemums. This will help conserve moisture and keep the roots cool during hot weather.
Winter Mulch: In colder climates, apply a thicker layer of mulch in late fall to protect the roots from freezing temperatures.
Pest and Disease Control
Chrysanthemums are relatively resistant to pests and diseases, but they can still be affected by common garden problems. Taking preventive measures can help ensure your plants remain healthy and produce more flowers.
Aphids: These small, sap-sucking insects can cause distorted growth and reduce flower production. Control aphids with insecticidal soap or by introducing beneficial insects like ladybugs.
Spider Mites: These tiny pests can cause stippling and discoloration of leaves. Control spider mites by regularly spraying your plants with water to knock them off or using insecticidal soap.
Fungal Diseases: Powdery mildew and leaf spot are common fungal diseases that affect chrysanthemums. Prevent these diseases by providing good air circulation, avoiding overhead watering, and applying fungicides as needed.

Light Requirements
Chrysanthemums require plenty of sunlight to produce abundant flowers. Here’s how to ensure they get the light they need:
Full Sun: Plant chrysanthemums in a location that receives at least 6 hours of direct sunlight each day. Full sun promotes vigorous growth and abundant flowering.
Shade Tolerance: While chrysanthemums can tolerate some shade, too much shade can lead to leggy growth and fewer flowers. If you notice your plants are not blooming well, consider relocating them to a sunnier spot.
Temperature and Climate Considerations
Chrysanthemums are adaptable to a wide range of temperatures, but they perform best in moderate climates. Understanding their temperature preferences can help you get more flowers.
Optimal Temperature: Chrysanthemums thrive in temperatures between 60-70°F during the day and 50-60°F at night. These conditions promote bud development and blooming.
Heat and Cold Stress: Extreme temperatures can stress chrysanthemums and reduce flower production. Provide shade during hot weather and protect plants from frost in colder climates.
Division and Propagation
Regularly dividing your chrysanthemums can help rejuvenate the plants and encourage more flowers. This process involves separating the root clumps and replanting them, which stimulates new growth.
When to Divide: Divide your chrysanthemums every 2-3 years in the early spring when new growth begins. This helps prevent overcrowding and encourages healthy, vigorous growth.
How to Divide: Carefully dig up the entire plant and use a sharp knife or spade to divide the root ball into smaller sections. Replant the divisions in well-prepared soil and water thoroughly.
Winter Care
Proper winter care is essential for ensuring your chrysanthemums come back strong and ready to bloom the following year.
Cutting Back: After the first hard frost, cut back the plants to about 6 inches above the ground. This helps prevent disease and prepares the plants for winter.
Mulching: Apply a thick layer of mulch around the base of the plants to protect the roots from freezing temperatures. In colder climates, consider covering the plants with a burlap or frost blanket for added protection.
Additional Tips for Maximizing Chrysanthemum Blooms
Rotate Your Crops: If you’ve been growing chrysanthemums in the same spot for several years, consider rotating them to a new location to prevent soil-borne diseases and nutrient depletion.
Avoid Overcrowding: Make sure your chrysanthemums have enough space to grow and receive adequate air circulation. Overcrowded plants are more susceptible to disease and produce fewer flowers.
Regular Monitoring: Regularly inspect your plants for signs of pests, diseases, or nutrient deficiencies. Early detection and treatment can prevent these issues from affecting flower production.
Conclusion
Growing chrysanthemums that produce an abundance of flowers requires attention to detail and consistent care. By selecting the right variety, preparing the soil, providing adequate water and nutrients, and following proper pruning and maintenance techniques, you can enjoy a stunning display of blooms throughout the growing season. Whether you’re a seasoned gardener or a beginner, following these guidelines will help you achieve the best results with your chrysanthemums and ensure a vibrant, colorful garden year after year.
