Wheatgrass is often used as a medicinal plant for humans as well as a nice snack for cats. Due to its intolerance of both hot and cold weather conditions, it is generally grown in small batches indoors. In order to survive, wheatgrass needs to stay in between 60 and 90 degrees Fahrenheit. However, if planted at the right times and in ideal conditions, wheatgrass can be successfully grown outdoors in the spring and fall seasons.
Soak the wheatgrass seeds in a bowl of water for 12 hours to soften the outer shell. Remove them from the water and let them air dry for an additional 12 hours.
Prepare a spot in a shady area to plant the seeds. Loosen the top inch of soil to make root growth easier.
Water the soil so it's just moist enough that it packs when pressed.
Sprinkle the wheatgrass seeds on the prepared soil. Try to lay around 10 seeds for every square inch of space. Press down lightly on the seeds with the palm of your hand to press them into the soil.
Keep the soil moist at all times. The seeds should germinate within a week.
Check the soil daily after the seeds germinate. Add water when the top of the soil begins to feel dry. Wheatgrass can survive short periods of drought, but it's best to keep the soil moist for the entire growth cycle.
