Can you mulch them good, Leo, and throw plastic over the beds if a hard frost is predicted?

I'm really enjoying the salad greens I planted in the pots. With just me one week, and just me and my son the other week, I am going to get a lot more mileage out of them than I thought I might. 2 advantages I had not thought of, are not having to bend so low to harvest baby greens, and NO SLUGS!

I agree Maggie, that growing yer own is worth the pleasure of doing it, the increased freshness and flavorfulness, even if it does cost more.   Even produce bought at the local farmer's market is never quite as good as what you eat 15 minutes out of the garden. And around here, we have some serious organic truck farmers who harvet throughout the week. Still a lot fresher than stuff trucked in from Florida, California or Mexico - but not as good as literally just picked.

I've got one pot of lettuce in bright shade and am wondering if I might be able to harvest lettuce a bit longer than is typical here, since they are protected somewhat from the heat.

I also wonder what it would be like to live where you can grow lettuce all season. Here, by the time the cukes and tomatoes are ready to start harvesting, lettuce and salad greens season is way past.
