Also keep them well watered, particularly during the first few weeks. To sprout well indoors, garden seeds need temperatures that are warmer than most Kansans heat their homes. So, gardeners may decide to place their planted seeds in a sunny window or near a furnace vent or register. This can create space problems. To keep those problems as limited as possible, however, gardeners can use the traditional approach to early seeding, said Chuck Marr, K-State Research and Extension horticulturist.
Seeds can sprout while they share just a few containers.
Shallow plastic flats now are the usual containers for mass seedings. You almost fill the container with a lightly firmed layer of a disease-free planting medium. Then you sow the seeds thickly in rows 2 inches apart. When the seedlings have two to four small leaves, they need to move into individual small pots. Then lift the stronger seedlings from the flat by grasping their leaves, not the stem.
