How to Make a Seed Tape
It's time to make more seed tapes because we have a lot of carrots to plant!
Why make your own? First, finding exactly the seed you want in a pre-made seed tape is almost impossible. Second, pre-made seed tapes are expensive! And third, it's easier to space the seeds by placing them on a seed tape than doing it in the garden with wind blowing those tiny carrot and herb seeds.
Here's how: Take a somewhat thin square of toilet paper... I usually use 3 squares as they are about 4" per square, so 3 squares x 4" each = 12". This works well when planning a square-foot garden. The pic above has 3 squares for the grouping of onions above. We use Angel Soft, or another really cheap brand. Always use white - you don't want dyes possibly affecting your seeds.
I put an ink-mark where I plan to place the seed. Remember to space them out according to your package unless you plan to transplant. Using washable elmer's glue or a paste made with flour and water, dot it where you want the seed, place the seed, place another sheet of toilet paper on top, and let it dry.
Be sure to write on the seed tape (in ink!) what you've made. Red bunching onion seeds look pretty much like white bunching onion seeds. And if you're planting 5 different carrots like we are this year, you'll need it.
After they are very dried, I store them flat in an oversized baggie.
When you're ready to plant (it's about time for lettuce, radishes and carrots), smooth the surface of the upturned soil where you want the plants to grow, and place the seed tapes on the surface. Cover with enough soil per instructions for the seed (a little more for the bigger seeds, and just barely any for the smaller like carrots). Gently water. Actually, I recommend you use a mister until the seeds have sprouted and have firm roots. It's not very pretty to have water (or rain!) displace the soil to leave the white toilet paper just hanging out there!
