Barley grass, or barley, is a grass and grain that has been grown since prehistoric times as a staple food. However, in recent years, it has become popular to grow barley as a "cat grass" to keep cats from "grazing" on prized houseplants. In addition, a number of nutritional systems recommend using barley grass as part of a juice or other nutritional supplement. As such, many people have become interested in growing barley grass at home. Although a somewhat complicated process, growing barley in pots is not difficult.
Put your barley seeds in a bowl. The number of seeds will depend on the size of your final pot or growing location.
Add water to your bowl. Use two to three times the volume of water as barley. The water should be between 60 and 70 degrees F.
Soak your barley overnight, or between eight and 12 hours.
Place the soaked seeds in your sprouter and place the sprouter in full sun.
Rinse and drain the seeds every eight to 12 hours until you see a small root.
Plant the sprouted barley in flowerpots filled with soil that drains well.
Water the seedlings thoroughly. Do not let them dry out.
After a week, your barley should be large enough to either use as a dietary supplement or as a cat offering to try to keep them away from your houseplants.
