Liatris, also known as blazing star or gayfeather, is a popular perennial flower admired for its tall spikes of vibrant purple flowers. Proper post-harvest care is essential to ensure the longevity and quality of cut flowers and to prepare bulbs for the next growing season.
Understanding Liatris Post-Harvest Needs
After blooming, Liatris requires specific storage techniques to maintain its freshness and vitality. Knowing how to handle the plant after harvest can significantly impact its future growth and flowering potential.
Harvesting Liatris
The best time to harvest Liatris is when the flower spikes are fully developed but before they start to fade. Use sharp scissors or pruning shears to cut the stems at the base, ideally in the morning when the plant is hydrated.
Preparing for Storage
Immediately after harvesting, remove excess foliage to prevent mold and disease. Handle the stems gently to avoid bruising or damage, which can reduce storage life.
Storage Techniques for Cut Liatris
Proper storage extends the vase life of cut Liatris and preserves its appearance. Follow these techniques for optimal results:
- Water and Hydration: Place stems in clean, water-filled vases immediately after cutting. Change the water every 2-3 days to prevent bacterial growth.
- Temperature Control: Keep the flowers in a cool, shaded area away from direct sunlight and heat sources. Ideal storage temperature is between 34°F and 40°F (1°C – 4°C).
- Use of Preservatives: Add floral preservatives to the water to supply nutrients and inhibit bacterial growth.
- Refrigeration: For longer storage, refrigerate cut Liatris in a plastic bag or container, maintaining high humidity and cool temperature.
Storing Liatris Bulbs
For bulb preservation, proper drying and storage are crucial. Follow these steps:
- Digging Up: Wait until the foliage has turned yellow or brown, indicating dormancy. Carefully dig up the bulbs to avoid damage.
- Cleaning: Gently brush off soil and allow bulbs to dry in a well-ventilated area for a week.
- Storage Conditions: Store bulbs in a cool, dark, and dry location, such as a paper bag or mesh container, at temperatures around 50°F (10°C).
- Monitoring: Check periodically for signs of rot or pests and discard any compromised bulbs.
Tips for Successful Post-Harvest Care
Implementing these tips can improve the quality and longevity of your Liatris after harvest:
- Use sharp tools to prevent crushing stems.
- Maintain cleanliness to avoid disease transmission.
- Handle flowers gently to prevent bruising.
- Keep flowers in a cool environment until they are used or stored.
- Label stored bulbs with the harvest date for proper rotation.
Conclusion
Proper post-harvest care for Liatris, whether for cut flowers or bulbs, ensures their beauty and vitality for future seasons. Following these storage techniques can help gardeners and florists enjoy Liatris’s vibrant blooms year after year.
