Last year I tried something new when I planted my zinnias from seed indoors. As you can see, my little newspaper pots worked better than the little peat pots that I usually buy. I think it is because they hold more potting soil and they decomposed faster after I planted them. First I planted my seed in a pie tin with potting soil. After they sprouted, I carefully transfer them to the homemade newspaper pots using a toothpick.
To make the pots, I cut newspapers into 4 strips. Roll a strip of newspaper around a can. I used a Pam can. Pull it partially off of the can and fold down the bottom, sealing with tape.
