Pat:
I make containers from newspaper and plant the whole thing.
I used this idea in the past 2 weeks for peas. Tried finding innoculent, but didn't find it, so I started peas in a paper towel in a dish with some water. Once the root sprout started coming out, I made newpaper cups around small square pots, then stuck them in the pots. Filled the bottom with good potting soil mixed with some peat, and the top half got seed starter mix. Planted the peas and they are starting to sprout! Soon I'll be planting the newspaper pea cups in a bed outside. Thanks for this idea!
BYW, for the first time I bought Red Pontiac (certified) seed potatoes. I've read about planting in cardboard boxes (filling with layers of mulch and dirt). I want to try this. Never grew potatoes before, so if anyone has tried the cardboard box method or has any tips or pointers, let me know.
