Harvesting goldenrod seeds is a great way to expand your garden! You’ll want to look out for the fluffy, white seed heads that form after the flowers have dried, which usually happens in late fall. Carefully cut these seed heads and place them in a paper bag to finish drying. Once completely dry, you can gently shake the bag to release the seeds.
For storage, keep the seeds in a cool, dry place, ideally in an airtight container. A glass jar or a sealed plastic bag in the refrigerator can work well to maintain their viability. Just ensure the seeds are completely dry before storing to avoid any mold.
Sharing seeds is a wonderful idea, and I’m sure your friends will appreciate the vibrant addition to their gardens! For more details, you might check out resources from local gardening clubs or university extension programs, which often have region-specific advice. Happy gardening!
