How to Encourage Liatris to Re-Bloom After Division

by

Growing Liatris, also known as blazing star or gayfeather, is a rewarding experience for gardeners who enjoy vibrant purple spikes. After dividing your Liatris, encouraging it to re-bloom can enhance your garden’s beauty and health. Here are some effective tips to promote reblooming.

Understanding Liatris Growth and Division

Liatris is a perennial plant that produces tall flower spikes with dense, purple florets. It thrives in full sun and well-drained soil. Dividing Liatris is usually done in early spring or late fall to rejuvenate the plant and control its size. Proper division helps prevent overcrowding and encourages vigorous growth.

Steps to Encourage Re-Blooming

  • Proper Timing: Divide Liatris in early spring or late fall when the plant is dormant or just starting to grow.
  • Adequate Spacing: When replanting divided sections, ensure they are spaced appropriately to allow for growth and airflow.
  • Soil Preparation: Amend the soil with compost or organic matter to improve drainage and provide nutrients.
  • Watering: Keep the soil consistently moist but not waterlogged, especially during the initial recovery period.
  • Fertilization: Apply a balanced, slow-release fertilizer in spring to support new growth and flowering.
  • Pruning: After the initial bloom, cut back the flower stalks to encourage new growth and potential reblooming.
  • Sunlight: Ensure your Liatris receives full sun, which is essential for optimal flowering.

Additional Tips for Success

Patience is key when encouraging rebloom. Some varieties of Liatris may rebloom later in the season, especially if conditions are favorable. Regularly monitor your plants for pests and diseases, and address issues promptly to keep your Liatris healthy and blooming.

Common Problems and Solutions

  • Leggy or Sparse Growth: Improve soil fertility and ensure adequate sunlight.
  • Poor Re-Blooming: Check for proper watering and fertilization; consider deadheading spent flowers to promote rebloom.
  • Pest Issues: Use appropriate organic or chemical controls for pests like aphids or spider mites.

By following these guidelines, you can enjoy a lush, reblooming Liatris that adds color and texture to your garden season after season.
