Here is an easy way to make little pots for your seeds this spring. They are easy to make, fully biodegradable and don't cost a penny.
Save your toilet paper rolls, paper towel rolls and any cardboard tubes you may have (I even found a long tube from gift wrapping paper that worked great). If your tubes are long cut them to the desired length then flatten them out so that they are square shaped
Cut along the edges of the toilet paper roll up about one inch
Then fold the flaps down and tuck the loose one under like you would with a box
Flip over and add your soil and a couple seeds. Once your seedling have grown and you have hardened them off you can plant the entire roll into the soil.
