How to Grow Wheatgrass Indoors

By Kathleen Sonntag ; Updated September 21, 2017

Wheat grass is known for its high nutrient content. It is primarily regarded as a beneficial detoxifier to help remove impurities from the blood and intestinal system. Growing wheatgrass indoors and harvesting it while it is young increases the nutritional value. It also offers you the opportunity to control the growing environment.

Soak wheatgrass seed for at least 12 hours in a clean quart jar or sprouting jar. Rinse it several times before leaving it to soak. The amount of seed depends on the planting container. Place the container on the counter in a cool location. The seeds may take longer than 12 hours to sprout.

Drain the water from the seed by covering the top of the jar with cheese cloth. You can also pour the seed into a colander or strainer, but place a paper towel in the bottom first to keep the seed from going through. Rinse the seed again before planting.

Plant the seed in wheatgrass trays or other planting containers by spreading it on top of a layer of organic soil. The seeds should be close together, but not in piles. Water by spraying gently using a spray bottle. Cover with a newspaper or tray cover to keep out light and retain the moisture. Place in a warm, dark spot for two to three days while the seeds start to grow. Keep the seeds moist.

Uncover the tray and move it to a sunny location near a window when the plants are about 1 inch high. Continue to water daily. Check to be sure the soil is damp but not saturated. Wheatgrass grows very quickly.

Cut the wheat grass at the bottom of the stem in eight to 10 days or when it is 8 to 10 inches in height. You can use scissors. Use it right away for best results, though it will keep in the refrigerator for a few days. Wash before using, store dry.
