Potted chrysanthemums, commonly known as mums, are a favorite among garden enthusiasts due to their vibrant colors and ability to brighten up any indoor or outdoor space. Caring for potted chrysanthemums involves a combination of proper watering, sunlight, soil management, and pest control. This guide will help you understand the key aspects of potted chrysanthemum care to keep your plants healthy and blooming.
Choosing the Right Pot and Soil
Pot Selection:
Choose a pot with good drainage holes to prevent water from stagnating, which can cause root rot. The pot size should be appropriate for the plant’s size, allowing room for the roots to grow but not so large that the soil remains wet for too long.
Soil:
Use a well-draining potting mix, preferably one designed for flowering plants. A mix containing peat moss, perlite, and vermiculite works well. You can also add compost to enrich the soil with nutrients.
Watering
Consistency is Key:
Chrysanthemums require consistent moisture, but they do not like to sit in waterlogged soil. Water the plant thoroughly when the top inch of soil feels dry to the touch. Ensure excess water can drain out of the pot.
Avoid Overwatering:
Overwatering is a common mistake. Ensure the pot has proper drainage and never allow the plant to stand in a saucer of water. Overwatering can lead to root rot and other fungal diseases.
Light Requirements
Sunlight:
Chrysanthemums thrive in bright, indirect sunlight. Place your potted mum in a location where it can receive at least 6 hours of sunlight each day. Too much direct sunlight, especially in the afternoon, can cause the flowers to wilt.
Indoors vs. Outdoors:
If you keep your chrysanthemums indoors, place them near a window with plenty of light. Outdoors, choose a spot that gets morning sun and some afternoon shade.
Temperature and Humidity
Optimal Temperature:
Chrysanthemums prefer cooler temperatures, ideally between 60-70°F (15-21°C) during the day and slightly cooler at night. Avoid exposing them to temperatures below 32°F (0°C).
Humidity:
While chrysanthemums do well in average humidity, they benefit from slightly higher humidity levels. You can increase humidity by placing a tray of water near the plant or using a humidifier.
Feeding and Fertilizing
Balanced Fertilizer:
Use a balanced, water-soluble fertilizer every two weeks during the growing season (spring through early fall).
A 10-10-10 or 20-20-20 fertilizer works well. Reduce feeding as the blooming period approaches.
Avoid Over-fertilizing:
Too much fertilizer can lead to excessive foliage growth at the expense of flowers. Follow the recommended dosage on the fertilizer package.
Pruning and Pinching
Pinching:
Pinching back the stems of your chrysanthemum will encourage bushier growth and more flowers. Start pinching when the plant is about 6 inches tall. Remove the top 1-2 inches of each stem, and repeat this process every few weeks until midsummer.
Pruning:
After the blooming period, cut back the plant to about 4-6 inches above the soil level. This helps the plant conserve energy and encourages new growth in the following season.
Pest and Disease Control
Common Pests:
Watch out for aphids, spider mites, and thrips. Use insecticidal soap or neem oil to treat infestations. Regularly inspect the plant and remove any affected leaves.
Diseases:
Chrysanthemums are susceptible to fungal diseases such as powdery mildew and botrytis blight. Ensure good air circulation around the plant and avoid overhead watering. If you notice signs of disease, remove affected parts and apply a fungicide if necessary.
Repotting
When to Repot:
Repot your chrysanthemum every 1-2 years in the spring to refresh the soil and provide more room for root growth. Choose a pot one size larger than the current one.
How to Repot:
Gently remove the plant from its current pot, loosen the roots, and place it in the new pot with fresh soil.
Water thoroughly after repotting to help the plant settle in.
Caring for potted chrysanthemums requires attention to detail, but the effort is well worth it when you see their stunning blooms. By providing the right conditions and care, you can enjoy these beautiful plants year after year. Remember to monitor your plant regularly and make adjustments as needed to keep your potted chrysanthemums thriving.
Seasonal Care Tips
Spring:
Begin watering more frequently as the weather warms up and the plant starts to grow actively.
Start fertilizing with a balanced fertilizer to support new growth.
Pinch back stems to promote bushier growth and more blooms.
Summer:
Continue pinching back stems until midsummer to encourage branching.
Ensure the plant receives adequate water, especially during hot, dry spells.
Watch for signs of pests and diseases, and treat them promptly.
Fall:
Enjoy the blooming period of your chrysanthemums. Maintain regular watering and deadhead spent flowers to encourage continuous blooming.
As the blooming period ends, reduce watering and stop fertilizing to prepare the plant for winter dormancy.
Winter:
If you live in a region with cold winters, bring the potted chrysanthemum indoors before the first frost.
Place it in a cool, bright location and reduce watering, allowing the plant to rest.
Alternatively, you can overwinter the plant in a garage or basement, watering sparingly to keep the soil from drying out completely.
Troubleshooting Common Problems
Yellowing Leaves:
Yellowing leaves can indicate overwatering or underwatering. Check the soil moisture level and adjust your watering schedule accordingly.
It could also be a sign of nutrient deficiency. Ensure you are providing balanced fertilizer during the growing season.
Wilting:
Wilting can occur if the plant is not getting enough water or is exposed to too much direct sunlight. Ensure the soil is consistently moist and move the plant to a location with indirect light if needed.
Lack of Blooms:
If your chrysanthemum is not blooming, it might not be getting enough light. Ensure it receives at least 6 hours of sunlight daily.
Over-fertilization with high-nitrogen fertilizer can also lead to lush foliage but few flowers. Use a balanced fertilizer and avoid overfeeding.
Leggy Growth:
Leggy growth usually results from insufficient light or lack of pinching. Ensure the plant receives adequate sunlight and pinch back stems regularly to promote bushier growth.
Propagation
Cuttings:
Chrysanthemums can be easily propagated from cuttings. Take 4-6 inch cuttings from healthy, non-flowering stems in late spring or early summer.
Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a pot with well-draining soil and keep it moist.
Place the pot in a bright, indirect light location until roots develop, usually in 3-4 weeks.
Division:
Every few years, you can divide your chrysanthemum plant to rejuvenate it and create new plants.
In early spring, gently remove the plant from its pot and separate the root clump into smaller sections, each with several stems and roots.
Plant the divisions in new pots with fresh soil and water thoroughly.
With the right care, potted chrysanthemums can be a delightful addition to your home or garden, offering vibrant color and a cheerful display of blooms. By following these guidelines on pot selection, watering, light, feeding, pruning, pest control, and seasonal care, you can ensure your chrysanthemums stay healthy and beautiful year-round. Regular monitoring and prompt attention to any issues will keep your potted mums thriving, allowing you to enjoy their beauty for many seasons to come.
Creative Display Ideas

Enhancing Bloom Longevity
Deadheading:
Regularly remove spent flowers by pinching or cutting them off just above the nearest set of leaves. This encourages the plant to produce more blooms and prevents it from wasting energy on seed production.
Optimal Environment:
Keep your chrysanthemums in a location with consistent temperatures and avoid sudden changes, which can stress the plant and reduce blooming.
Ensure they receive adequate light, but protect them from harsh, direct afternoon sun, which can cause the flowers to fade quickly.
Proper Feeding:
Continue to feed your chrysanthemums with a balanced fertilizer during the blooming season to support continuous flower production.
Reduce fertilizing once the blooming period is over to help the plant transition into dormancy.
Preparing for the Next Season
Post-Bloom Care:
After the blooming period, cut back the plant to about 4-6 inches above the soil. This helps conserve the plant’s energy for the next season.
Gradually reduce watering and prepare the plant for dormancy by keeping it in a cool, bright location.
Winter Storage:
For outdoor chrysanthemums, consider mulching around the base of the plant to protect it from harsh winter temperatures.
Indoor chrysanthemums should be kept in a cool, well-lit area, with minimal watering to keep the soil slightly moist.
Spring Revival:
In early spring, gradually increase watering and begin fertilizing to encourage new growth.
If necessary, repot the plant with fresh soil and a slightly larger pot to accommodate new root growth.
Move the plant to a sunnier location to support vigorous growth and prepare for pinching and shaping.
