How to Grow and Care for Fall-Blooming Chrysanthemums

by

Fall-blooming chrysanthemums, often called mums, are a popular choice for adding vibrant color to gardens as the season changes. With proper care and cultivation, these hardy plants can provide stunning blooms year after year. This guide will walk you through the essential steps to grow and care for fall-blooming chrysanthemums successfully.

Choosing the Right Chrysanthemum Varieties

There are many varieties of chrysanthemums suitable for fall blooming. When selecting plants, consider factors such as flower color, size, and growth habit. Popular types include:

  • Garden mums (hardy varieties)
  • Pot mums (more decorative but less hardy)
  • Pompon and spider varieties for unique shapes

Planting Chrysanthemums

Timing is crucial for planting chrysanthemums. For hardy varieties, plant in early spring after the danger of frost has passed. For potted or nursery-grown mums, planting in late spring or early summer is ideal. Follow these steps:

  • Choose a location with full sun, at least 6 hours daily.
  • Ensure well-draining soil rich in organic matter.
  • Space plants about 18 to 24 inches apart to allow airflow.
  • Plant at the same depth as in their nursery containers.

Watering and Fertilizing

Consistent watering is vital, especially during dry spells. Chrysanthemums prefer moist, but not waterlogged, soil. Fertilize regularly to promote healthy growth and abundant blooms:

  • Use a balanced fertilizer (e.g., 10-10-10) every 4-6 weeks.
  • Reduce fertilization as the plants approach flowering.
  • Avoid over-fertilizing, which can lead to lush foliage but fewer flowers.

Pruning and Pinching

Pruning encourages bushier growth and more flowers. Begin pinching back the plants in early summer to promote multiple stems. Remove spent blooms to extend flowering and maintain plant health:

  • Pinch out the tips when plants are about 6 inches tall.
  • Repeat pinching every few weeks until mid-July.
  • Remove faded flowers regularly.

Overwintering and Care for the Next Season

In colder regions, hardy chrysanthemums can survive winter if properly protected. Mulch heavily around the base of the plants after the first frost to insulate roots. In milder climates, leave plants in the ground and prune back in late fall. For potted mums:

  • Bring them indoors before the first frost.
  • Place in a cool, bright location during winter.
  • Reduce watering during dormancy.

Additional Tips for Success

To ensure your chrysanthemums thrive:

  • Maintain good air circulation around plants.
  • Avoid overhead watering to prevent disease.
  • Monitor for pests such as aphids and spider mites.
  • Use organic controls if necessary.

With attentive care, your fall-blooming chrysanthemums will reward you with vibrant, cheerful flowers that brighten your garden during the autumn months. Happy gardening!
