The wine barrel container gardens are growing nicely. I do think they got a head start due to coveirng with plastic. Now I'm leaving them uncovered, except for some chicken wire to discourage birds.
Everything has sprouted, with the exception of the old chinese celery and the onion seeds. Maybe they just need a little more time. The seeds that have sprouted and are growing actively are spinach, chinese radish, radish, brassica mesclun, lettuces, and cilantro. I don't know if they will give edibles in the claimed 20 to 30 days, since it's chilly. Still, very encouraging.
