Delphinium blooms are a favorite among florists for their tall, elegant spikes and vibrant colors. Proper harvesting techniques ensure the longevity and beauty of these flowers in arrangements. Understanding the best practices can help florists maximize the quality of their delphinium displays.
Understanding the Life Cycle of Delphinium
Delphiniums are perennial plants that bloom in late spring to early summer. They develop tall flower spikes that can reach up to 6 feet, depending on the variety. Recognizing the optimal harvest time is crucial for obtaining fresh, long-lasting blooms.
Timing the Harvest
The best time to harvest delphinium blooms is when the buds are fully developed but before they start to fade. Typically, this is when the lower buds are open, and the upper buds are still in the process of opening. Harvesting during this window ensures the flowers will last longer once cut.
Signs of Peak Bloom
- Color is vivid and consistent across the spike
- Lower buds are fully open
- Upper buds are swollen but not yet opened
Tools and Preparation
Use sharp, clean pruning shears or floral scissors to make clean cuts. Prepare a bucket of clean, lukewarm water to place the harvested flowers immediately after cutting. Wearing gloves can help prevent damage to the delicate stems.
Harvesting Technique
Follow these steps for optimal harvesting:
- Identify the ideal bloom stage as described above.
- Cut the flower spike at a 45-degree angle about 1/4 inch above a leaf node or just above a set of leaves.
- Immediately place the cut stems into the prepared water to prevent air from entering the stem.
- Repeat for all selected blooms, working in the early morning or late afternoon for best results.
Post-Harvest Care
After harvesting, remove any lower leaves that will be submerged in water to prevent bacterial growth. Keep the flowers in a cool, shaded place until they can be arranged or further processed. Recut stems before arranging to improve water uptake.
Maximizing Vase Life
To extend the life of delphinium blooms:
- Change the water regularly, at least every two days
- Add floral preservative to the water
- Keep flowers away from direct sunlight and heat sources
- Recut stems at an angle every few days
Conclusion
Harvesting delphinium blooms with care and attention to timing ensures the flowers remain vibrant and long-lasting. Proper tools, techniques, and post-harvest care are essential for florists aiming to create stunning arrangements that showcase the delicate beauty of these iconic flowers.
