Cow Pots. I just followed this link from the National Gardening Association Regional Newsletter. http://www.freundsfarmmarket.com/cowpots/index.html.htm
Looks like a great idea. The peat pots I've used in the past never seem to let the roots grow through. Even though I put a bunch of holes in the pot with my thumb nail at plant time, the pots end the summer intact. I noticed that the pots don't degrade when I re-potted annuals from the garden to bring inside to take cuttings for the next summer.
I may give them a try this year.
