Cut a narrow strip of newspaper.
Use a baggie to mix a slurry of flour and water (pancake batter consistency).
Cut off a small bit of baggie corner and dispense drops of flour mix onto paper in intervals. (1-1/2” for carrots).
Sprinkle seeds lightly over the wet drops. If they don’t stick press a few into each drop of flour mix and discard excess seeds.
Once tape is dry, lightly bury the tape. Then water as you would for regular seedlings.
