Mary, I went ahead and seeded my pots with lettuce, kale, spinach and mesclun mix this weekend, (and onion sets in a long planter for green onions,) and know I am pushing the envelop a bit. But like you said, seeds are cheap, and there are more of them in the envelops!

I've never tried veggie container gardening before.    There is only me to feed, and every other week my son, so I don't need to produce much from a salad garden. I'll be curious to see how it goes.

Mid-February is when I usually have usually seeded most of what I seeded in pots this weekend, but it was always in a cold-frame or tunnels. Maybe I should cover the pots with seran wrap?
