Collect seeds
Two-year-old dandelion plants can blossom and seed in the wild. In early summer, the number of flowering and fruiting seeds increases with the growth years. Some plants have more than 20 flowers, and the number of flowers per plant of excellent varieties can be as high as 20. After flowering, the seeds will mature in 13 ~ 15 days.
The shell of the disk changes from green to yellow-green, and the seeds can be harvested from ivory to brown. Don't wait for the disc to crack before harvesting, otherwise the seeds will easily fly away and lose a lot. Generally, the number of seeds per flower head is above 100.
When collecting seeds, you can take off the dandelion's disk and store it indoors for a day. After the disk is completely scattered, dry it in the shade for 1 ~ 2 days until the seeds are half dry, rub off the fluff at the tip of the seeds by hand, and then dry the seeds for later use.
