Collecting seeds is an easy way to expand your garden. Best of all, it’s free! To collect black-eyed Susan seeds, wait for a dry fall day and clip the seed heads off your plants. If they’re still green, lay them out to dry on a newspaper for a couple weeks. Once the seed heads are good and dry, pop them off the stems and place them in a glass jar. Then close the lid and shake shake shake!
Hold a sieve over a sheet of paper and dump the contents of the jar into it. The tiny black-eyed Susan seeds should fall through onto the paper. You’ll get a little bit of chaff as well, but that’s okay. When you plant your seeds, the extra bits will just go back into the ground. Once you’ve separated your seeds, put them in a paper envelope and store them in a cool dry place, then plant them in the spring.
