Deeply Rooted
Newspaper is potentially toxic, peat is nonrenewable, but there are always Cow Pots! Pricey, I know, but totally degradable and nourishing at the same time.
As for peat pots not disintegrating, I've always ripped the rim off to make sure it's totally underground when I plant them (I don't buy them, but sometimes plants come in them), or I rip them off completely, without ruining the rootball integrity. I use a styrofoam planting system I bought from Gardener's Supply many years ago to grow my seedlings. I'm very happy with them.
