Celery from seed was a complete bust for me. Nothing, nothing came up. Good thing I have those four Tango celery in a pot that I cheated and bought as seedlings. And looks like if I want parsely I am going to have to buy seedlings as nothing came up in my parsley bowl either. My dill bowl came up but not my cilantro bowl. I have a tomatillo plant this year for salsa and I need the cilantro. Humm, I think I will go out now and just scratch up the potting mix in those bowls and resow the seed. Nothing to loose by doing that.
