How can one obtain weed seeds?

To get weed seeds you first have to spot the weeds you want to harvest, generally in

the spring when they are flowering. Keep an eye on them as the mature and begin to

die. The seeds are generally contained in the old flower head. So collect the flower heads after the blooms have died and the seeds have had time to grow. Once you

have the flower heads. Separate and label them as seeds all look alike once they are

removed from the flower head. Let the flower heads dry out completely. I put the

flower heads in individual paper bags, lunch sacks work great, label the bags and let

them sit in a cool, dry place. After about a month they should be dry enough to fall

out of the old flower head, which you can now throw away. Wait until the following spring and plant your seeds. Happy growing!!
