Joanne, I've been saving half gallon milk jugs but that's as far as I've gotten. I'm worlds worst procrastinator so it may be another year or two before I make an attempt.
There is so much to read and browse through on that website, I still haven't read every area and link. I've heard lots of positive comments from gardeners that use this method though so I do want to try it. I've had miserable luck with trying to start
seeds indoors in the late winter\early
spring. Marigold, Morning Glories and Hyacinth Bean Vine have been my only successes. I either kill them with kindess or neglect...no happy medium. lol!
I think your idea of the paper pots is excellent. Be sure to let your helper
plant seeds of her own and you'll make a lifetime gardener out of her.
You can plop the whole thing in your planting hole and not disturb the roots as the paper will break down.
I saw an episode of Gardening by the Yard that Paul James actually planted some
seeds in egg shell halves. When it was time to
plant out, he lightly crushed the shell and planted the whole thing. I guess the shell provided extra nutrients? I can't remember all the details.
