Hi. I broadcast a bunch of seeds, Spinach, Chard, Bok Choy and only the Chard came up, so I did it again. The last seeding was a bit over three weeks ago. Chard is doing fine considering I am in San Francisco and there is little sun, and plenty of snails. Between the Chard plants there is a zillion of starters , but are they edible? I am attaching two photos of the area in question. Are these smaller plants Spinach? I would take this to a garden shop here in SF, but nobody knows a thing... Thanks, Mike
