Growing Wheat Grass:
How to Grow Wheatgrass Organically

Growing wheat grass outdoors is challenging, so most gardeners choose to grow it inside in a more controlled environment where it is very simple to grow. Wheatgrass can grow in virtually any soil (actually, it doesn't even need soil to grow!), but the higher the quality of soil, the more nutritious your wheatgrass will be.

In a controlled indoor environment, wheatgrass is very easy to grow.

As you may have noticed in your local smoothie shop, wheatgrass doesn’t need soil to grow. But if you allow it to grow in soil, the more nutritious the soil is, the healthier your wheatgrass will be.

To prepare the seeds, first soak them for about half a day and allow them to drain for the same amount of time. Next, sprinkle them onto any porous surface (they will grow literally anywhere as long as they can “grab ahold”) or directly on top of the soil. A porous surface will allow the root to attach and hold the plant upright. If you use soil (highly recommended), use an organic potting mix or a thin layer of well-composted soil.

Wheatgrass grows best in temperatures that are 60 to 75 degrees Fahrenheit (15.6-21.1 degrees C) until they are about ¼ to ½ inch (0.64 to 1.27 cm) high, after which they will tolerate lower temperatures.

  • Germination soil temperature: 60 to 70 degrees F (15.6 to 21.1 degrees C)

  • Days to germination: 12-18 days

Keep your newly planted wheatgrass seeds continually moist but not soaked. Keeping them covered with a slightly damp paper towel is an easy way to retain moisture.

If your climate is above 80 degrees Fahrenheit (26.7 degrees Celsius), make sure to have proper air ventilation to prevent mold.

After your wheatgrass reaches a height of just over one inch (2.5 cm), remove the cover and set it near a window that does not receive direct sunlight.

Growing Wheat Grass: Harvesting Time

You can start harvesting wheatgrass when a second blade begins to branch out from the stalks. Be careful not to overgrow your wheatgrass, as its taste will change if you leave it unharvested for too long.
