Just a quick update from the garden today: The Walla Walla onion seeds have finally matured, so I'm harvesting them to save for starting next year's onions. I hear starting onions from seed is the hardest way to grow onions in the home garden, but they tend to bulb without flowering as much, which is a good thing! (Bulbs that send up flower stalks get really spongy centers.)
I could tell these little guys were ready to be picked because the flower stem was completely yellowed and dry, and the flowers were opening up, revealing the black seeds ready for dispersal. I picked the whole head and crumbled the flowers to release the seeds, and I'm saving the seeds in a plastic baggie for next year!
