Harvesting Seeds:
Timing: Giant Ornamental Allium seeds are usually ready for harvesting when the seed heads have dried out and turned brown on the plant.
Collection: Cut the seed heads from the plant once they have dried. Place them in a paper bag to catch any seeds that may fall during handling.
Drying: Allow the seed heads to continue drying in a warm, well-ventilated area until they are fully dry. This usually takes a few weeks.
Extraction: Once the seed heads are fully dry, gently crush them to release the seeds. Remove any remaining plant material to obtain clean seeds.
Caring for Seeds:
Storage: Store the seeds in a cool, dry place in an airtight container, such as a labeled envelope or glass jar. Make sure the container is sealed tightly to prevent moisture from entering.
Labeling: Clearly label the container with the date of harvesting and the type of seeds to keep track of them.
Temperature: Aim to store the seeds at a consistent temperature, preferably between 40°F and 50°F (4°C and 10°C), to maintain their viability.
Moisture: Keep the seeds dry to prevent mold or fungal growth. Avoid storing them in areas prone to humidity.
Caring for Giant Ornamental Allium Plants:
Planting: Choose a sunny location with well-draining soil to plant Giant Ornamental Allium bulbs. Plant them in the fall, about 6-8 inches deep and 12-18 inches apart.
Watering: Water newly planted bulbs thoroughly to help them establish roots. Once established, Giant Ornamental Allium plants are drought-tolerant and generally do not require much watering.
Fertilizing: Apply a balanced fertilizer in the spring when new growth appears to support healthy plant development.
Pruning: Deadhead spent flowers to encourage continuous blooming and prevent self-seeding, as Allium giganteum can self-sow prolifically.
Dividing: Every few years, dig up and divide overcrowded clumps of Giant Ornamental Allium bulbs to maintain plant vigor and prevent overcrowding.
Pest and Disease Control: Monitor plants for signs of pests or diseases, such as onion flies or fungal infections, and take appropriate action, such as applying insecticidal soap or fungicides if necessary.
