Plant your catgrass seeds in pots, or in a well-worked garden bed. Make sure the top 2 inches of soil is loose.
Plant seeds directly on the surface of your planting material. Lightly cover with additional planting mix or soil, no thicker than a light dusting, Water with as fine a spray as possible, making sure that the water doesn’t pool (the seeds can float off into clumps). Keep the planting bed moist until you see germination (up to 21 days). Once the plants have reached 1” in height you can begin to water more liberally.
