Your idea about hanging them is a good one. I would put them in paper bags, upside down, somewhere warm and sunny and let the seeds fall when they’re ready. If the flowers have all dropped, I think it’s safe.
I discovered a few ‘surprise’ lettuce seedlings when I was scrounging around, yesterday - soon to be replanted. Red Romaine. Yay!
Great thanks, I have fluffy and dry on the flowers. I usually use a paper bag and have a good place in the garage to hang things. Nice find on the lettuce. I had the most gorgeous romaine this year. I used to start from seed in a barrel with a glass window over it at Easter time and transplant later. Then for several years I have just bought plants. I’m looking into a hanging LED gro light panel to start my own in the basement with a timer.
