Cardinal flowers (Lobelia cardinalis) are a stunning addition to any floral arrangement, known for their vibrant red color and tall, elegant spikes. Harvesting these flowers at the right time and using proper techniques can ensure they stay fresh and beautiful in your arrangements. This guide will walk you through when and how to cut cardinal flowers for the best results.
Best Time to Harvest Cardinal Flowers
The optimal time to cut cardinal flowers is when the blooms are fully open but not yet starting to fade. This ensures the flowers are at their peak color and vitality, which helps them last longer once cut. Typically, this is during the late morning after the dew has dried but before the heat of the day intensifies.
Look for flowers that display vibrant, deep red petals with a firm, upright spike. Avoid flowers that are wilting, browning, or showing signs of fading. Harvesting at this stage guarantees the best color and longevity in arrangements.
Tools Needed for Cutting
- Sharp pruning shears or scissors
- Clean cloth or alcohol for disinfecting tools
- Bucket of water for immediate placement of cut flowers
How to Cut Cardinal Flowers
Follow these steps to harvest cardinal flowers effectively:
- Disinfect your cutting tools to prevent disease transmission.
- Choose a healthy, fully bloomed spike during the optimal time of day.
- Cut the spike just above a leaf node or set of leaves, about 4-6 inches below the bloom.
- Make a clean, angled cut to increase water uptake and reduce damage.
- Immediately place the cut stems in a bucket of water to keep them hydrated.
Post-Harvest Care
After harvesting, remove any lower leaves that might fall below the water line to prevent rot. Keep the flowers in a cool, shaded area until you are ready to arrange them. For longer vase life, recut the stems every few days and change the water regularly.
Additional Tips for Success
- Harvest early in the day when flowers are most turgid and fresh.
- Use clean tools and containers to prevent infection.
- Keep the flowers away from direct sunlight and heat sources.
- Combine with other fresh flowers and greenery for a balanced arrangement.
By following these guidelines, you can enjoy the vibrant beauty of cardinal flowers in your floral designs, ensuring they stay fresh and striking for as long as possible.
