Caring for Chrysanthemums indoors is considered a medium-level task, primarily because they require a bit more attention to light and watering than some other indoor plants. These plants are highly valued for their long-lasting flowers and the extensive range of colors available, from bright yellows and whites to deep reds and purples. Beyond their aesthetic appeal, Chrysanthemums are known for their air-purifying qualities, making them a functional and beautiful choice for any plant lover.

Light Needs

Chrysanthemums thrive in bright, indirect sunlight. They prefer to be placed in a spot where they can receive at least 5-6 hours of sunlight a day but should be shielded from the harsh midday sun, which can damage their delicate flowers. A spot near an east or west-facing window is ideal, offering the perfect balance of light to encourage vibrant blooms.

Soil Type

A well-draining, fertile potting mix is essential for Chrysanthemums. They prefer slightly acidic to neutral soil, with a pH range of 6.5 to 7.0. Enhancing your potting mix with organic compost can provide the nutrients these flowering plants need to thrive and produce an abundance of blooms.

Watering Preferences

Consistent moisture is key to keeping your Chrysanthemum healthy, especially during the blooming period. Water the plant thoroughly when the top inch of soil becomes dry to the touch, ensuring that excess water drains away to prevent root rot. Be mindful not to wet the leaves and flowers, as this can lead to fungal diseases.


Chrysanthemums prefer average indoor humidity levels but will appreciate a bit of extra humidity during the dry, winter months. If your indoor air is particularly dry, consider using a pebble tray with water or a humidifier to increase humidity around your plant.

Ideal Temperature Range

Chrysanthemums enjoy cooler temperatures, ideally between 60-70°F (15-21°C) during the day and slightly cooler at night. Avoid placing your plant near heat sources or in areas with drastic temperature changes, as this can stress the plant and affect its flowering.


Repotting is usually necessary every one to two years to prevent your Chrysanthemum from becoming root-bound and to replenish its soil with fresh, nutrient-rich mix. Choose a pot that’s slightly larger than the current one and repot in the spring before the new growth cycle begins.


Pruning is crucial for maintaining a bushy, well-shaped Chrysanthemum. After flowering, cut back the stems to about 8 inches to encourage healthy growth and more blooms in the next season. Regularly remove any dead or wilted flowers to keep the plant looking its best.


Propagation of Chrysanthemums is typically done through cuttings or division:

  • Cuttings: In early spring, take 4-6 inch stem cuttings from a healthy plant, remove the lower leaves, and plant them in a moist, well-draining potting mix. Cover with a plastic bag to retain humidity until new growth appears.
  • Division: Divide the root ball during repotting, ensuring each section has roots and shoots. Replant each section in its own pot.

Common Pests

Chrysanthemums can encounter a few pests and issues:

  • Aphids: Small, sap-sucking pests that can cause stunted growth. Rinse off with water or treat with neem oil.
  • Spider Mites: Cause yellowing and webbing on leaves. Increase humidity and wash the plant with soapy water.
  • Powdery Mildew: A fungal disease that appears as white powder on leaves. Ensure good air circulation and avoid overhead watering.

Common Growth Issues

  • Leggy Growth: Caused by insufficient light. Move to a brighter location.
  • No Blooms: Lack of light or incorrect temperature can affect blooming. Ensure adequate light and cooler temperatures.
  • Yellow Leaves: Overwatering or poor drainage. Allow the soil to dry slightly between waterings and ensure good drainage.

Frequently Asked Questions

Chrysanthemums carry diverse meanings across different cultures. In general, they symbolize longevity, fidelity, joy, and optimism. In Japan, chrysanthemums are celebrated during the Festival of Happiness, symbolizing the sun and the emperor, reflecting longevity and rejuvenation. In China, they represent a life of ease and longevity. In Western cultures, chrysanthemums are often given as gifts to express well wishes, support, and friendship. The color of the chrysanthemum also affects its meaning—white chrysanthemums are associated with loyalty and honesty, while red mums symbolize love and deep passion.

The lifespan of a chrysanthemum flower can vary depending on the care it receives and the environment in which it grows. Generally, chrysanthemum blooms can last between 3 to 4 weeks when properly cared for. Factors such as temperature, light, and water play significant roles in the duration of their bloom. In gardens, mums typically flower in the fall, offering a late-season burst of color until frost. When grown indoors or as part of a floral arrangement, their longevity is influenced by indoor conditions, such as consistent temperatures and avoiding direct sunlight.

Yes, chrysanthemums can survive indoors with the right care, though they are traditionally grown outdoors. To thrive indoors, mums require:

  • Bright, indirect sunlight: Place them near a window that receives ample sunlight but is shielded from the direct rays of the sun.
  • Regular watering: Keep the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out before watering again.
  • Good air circulation: Ensure the plant is not cramped or in a stuffy location to prevent disease.
  • Proper temperature: Mums prefer cooler conditions, ideally between 60°F to 70°F (15°C to 21°C) during the day and slightly cooler at night.

After blooming, indoor mums can be moved outdoors to a partially shaded spot to continue growing. With annual pruning and proper winter care, they can be encouraged to bloom again in the following season.


Chrysanthemums bring a burst of color and life to any indoor setting, and with the right care, they can flourish and bloom spectacularly.
