Once seeds start coming up you can save them the way they are in the paper tubes and transfer to a pan to take to your garden or you can replant them in another type of container to continue to grow. See REPLANTING SEEDLING FOR FARMERS MARKET video.
pencil holder video. My paper square for making the size box I needed were 8X16 and 10.5 X 21. I folded the newsprint in half for either an 8 x 8 or 10.5 x 10.5.
Newsprint is light and I wanted a heavier construction for the planter so it would hold up with all the handling I would be doing and all the watering.
Look closely at the picture and you will see the very tip of the flat box cut off. This creates a hole for water drainage. Although water will seep through the paper I gave it a route of least resistance. Before pushing the paper into a box shape I wrote on in inside flaps the name of the plant.
Water new mix in well.
When planting, plant entire box. Cover box with soil completely, do not allow paper to be exposed to air and sun..you want the entire box to decompose.
