Hollyhocks are beautiful, tall flowering plants that add color and charm to any garden. Harvesting seeds from hollyhocks allows you to propagate new plants and enjoy their blooms year after year. After dividing your hollyhock plants, collecting seeds is an essential step to ensure successful propagation.
Understanding When to Harvest Hollyhock Seeds
Knowing the right time to harvest seeds is crucial for viability. Hollyhock seeds are ready to collect when the seed heads turn brown and dry out. Typically, this occurs in late summer or early fall, depending on your climate and planting schedule.
Preparing for Seed Collection
Before harvesting, gather the necessary tools: a pair of scissors or garden shears, a clean container or envelope, and gloves if desired. Wearing gloves can help prevent staining from the seed heads’ natural pigments.
Identifying Ripe Seed Heads
- The seed head has turned brown and feels dry to the touch.
- It may begin to loosen from the stem naturally.
- The seeds inside are dark and hard.
Harvesting the Seeds
To harvest, carefully cut the seed heads from the plant using scissors or shears. Place them in a paper bag or envelope to prevent moisture from causing mold or rot.
Once collected, gently shake or tap the seed heads to release the seeds. If necessary, you can also break open the seed heads to access the seeds inside.
Cleaning and Storing Seeds
After harvesting, spread the seeds on a paper towel or screen to remove debris and chaff. Allow them to dry completely in a cool, dry place for several days.
Store the dried seeds in an airtight container or paper envelope. Label with the date and variety for future reference. Keep seeds in a cool, dark location until planting time.
Tips for Successful Seed Propagation
- Plant seeds in well-draining soil in early spring or late fall.
- Provide adequate sunlight and water for optimal growth.
- Consider stratifying seeds by chilling them in the refrigerator for a few weeks to improve germination.
- Be patient; hollyhocks can take a year or more to bloom from seed.
By following these steps, you can effectively harvest and store hollyhock seeds after dividing your plants, ensuring a thriving garden filled with vibrant blooms for seasons to come.
