I've been using this method for years. I Fill a plastic pots to the half with seed starting potting mix, i drop three sprouted seeds in every pots and i gently cover to the top. I use a spray to
water smoothly. The soil
should stay constantly moist, but not soggy. My sweet peas will emerge in three or four days. By this way i will have a very good start and won't have to worry about birds and rotting seeds!
