Instead of buying expensive prepared seed tapes you can make your own. Cut newspaper into 1″ wide strips. Create a paste from flour and water about the consistency of thick gravy. Dot the paste on the newspaper strip at evenly spaced intervals and apply the seeds. Cover the seeds with more paste, then lay the seeds aside to dry. You can store the seed tapes in a plastic container or bag until you are ready to plant.
When you are ready to plant, simply roll out the seed tape, cover with soil and water them in with water mixed with your favorite organic fertilizer. The newspaper will rot away as the seeds grow.
