The luckiest of gardeners has her own greenhouse. While the rest of the gardening world is impatiently waiting out the winter, the greenhouse gardener is tending to her indoor plants. Growing your own grass plugs in a greenhouse is an easy project for the do-it-yourself type of person. Grass grown in a greenhouse will not be as thick as that grown outdoors, according to agriculturists at Michigan State University.
Fill each cell of the seed-starting tray to within 1/4 inch of the top. Water the soil well and allow the excess water to drain from the bottom.
Sprinkle the seeds in each cell. Apply enough seed so that you can barely see the soil, but don’t pile them on top of one another.
Cover the seeds with a light sprinkling of the soil/compost mixture and pat the soil with your hands. This will assure good contact between the seed and the soil.
Place the seeding tray under lights, in an area of the greenhouse where the temperature will remain between 40 and 50 degrees F.
Mist the soil to maintain its moisture. Never allow the seeds to dry out.
