How to Harvest Delphinium Seeds Successfully: Tips and Techniques


Understanding The Delphinium Life Cycle

Delphinium seeds, when harvested, can be an excellent addition to your garden. To gather them, you must understand the delphinium life cycle. It starts with planting the seeds in the spring and waiting for them to sprout. Once they grow, delphinium blooms for a period of about 4-6 weeks, and then the petals fall off.

After that, the plant begins to produce seeds that can be collected in late summer to early fall. To ensure the seeds are ready for harvesting, wait until they have changed their color and hardened. Once ready, remove the seed pod by cutting the stem below it and allowing it to dry indoors.

Once dry, gently crush the pod to extract the seeds. Remember, delphinium seeds are small and should be stored in a dry and cool place for use in the spring.

Starting With The Harvest

Harvesting delphinium seeds can be a simple process if you follow these guidelines. Firstly, wait until the flowers have bloomed and the seed pods have turned brown and dried out. Then, carefully cut the stem below the seed pod and place it in a paper bag.

By following these simple guidelines, you can successfully harvest and store delphinium seeds for use in your garden.
