Calendula, also known as pot marigold, is a popular garden flower valued for its vibrant orange and yellow blooms. For gardeners in Zone 7, harvesting seeds at the right time ensures a continuous supply of these cheerful flowers year after year.
Understanding Calendula Blooming and Seed Maturity
Calendula typically blooms from early spring to late fall in Zone 7. The seeds are ready for harvest when the flower petals have fallen, and the seed heads turn brown and dry. Recognizing the right stage of seed maturity is crucial to ensure viable seeds for planting.
When to Harvest Calendula Seeds in Zone 7
The ideal time to collect calendula seeds is in late fall, after the flowering period has ended and the seed heads have dried completely. In Zone 7, this usually occurs between October and November, depending on local climate conditions and the specific planting time.
Signs of Seed Readiness
- The seed heads have turned a dark brown or black color.
- The seed pods feel hard and dry to the touch.
- The flowers have faded and no new blooms are appearing.
How to Collect Calendula Seeds
To harvest seeds, wait until the seed heads are fully dry. Gently cut the seed heads from the plant using scissors or pruning shears. Place them in a paper bag or a breathable container to prevent mold during storage.
Once collected, you can further dry the seed heads in a warm, dry place for a few days to ensure they are completely dry before storing or planting.
Storing Calendula Seeds
Store calendula seeds in a cool, dark, and dry location. Use airtight containers or paper envelopes to protect them from moisture and pests. Proper storage can keep seeds viable for 2-3 years.
Tips for Successful Seed Saving
- Choose healthy, disease-free plants for seed collection.
- Label seed containers with the date and plant variety.
- Allow seed heads to mature fully before harvesting.
- Keep seeds dry during storage to prevent mold and rot.
By following these guidelines, gardeners in Zone 7 can enjoy a sustainable cycle of calendula cultivation, ensuring vibrant blooms season after season.
