How to Germinate Ornamental Grass Seed

In the late summer, as you sit outside enjoying the last of the season's warmth, the slightest breeze can turn ornamental grasses into a fascinating focal point. While the flowers are minuscule, green and uninteresting, the seedhead that forms makes the grass more complex and pleasant to watch. Some ornamental grasses are expensive and difficult to obtain, but you can collect ornamental grass seed in the wild or order it from native nurseries. Starting grass seed indoors is not difficult and can save you money.

Instructions

    • 1

      Soak the 2-liter bottle in warm water and remove the label. You don't have to remove the whole label from the bottle, just most of it.

    • 2

      Drill five holes in the bottom of the 2-liter bottle for drainage.

    • 3

      Add 3 inches of sharp sand to the bottom of the 2-liter bottle.

    • 4

      Dampen the sand by pouring water into the top hole of the 2-liter bottle. Allow excess water to drain out the holes in the bottom.

    • 5

      Mix 1/2 teaspoon of grass seed with 1 cup of seed-starting mix to disperse the seed evenly. This should be done in late February.

    • 6

      Pour 1/2 inch of the grass and seed-starting mix through the whole at the top of the 2-liter bottle. Gently shake the bottle from side to side to disperse the grass seed evenly across the top of the sharp sand.

    • 7

      Replace the lid on the 2-liter bottle and allow the grass seed to germinate. Add a small amount of water at a time if the grass seed begins to dry out.

    • 8

      Remove the cap from the bottle once the seed has germinated and begins to grow. Add water with liquid fertilizer while the grass is growing. Place the growing grass into a brightly lit window. Cut the top off the plastic 2-liter bottle with a razor knife. Remove the grass and plant it outside in the spring once the temperature is acceptable for the species of grass you are growing.
