How to Plant Black Mondo Grass Seeds

Wait until mid to late winter when the berries on the black mondo grass turn completely black with no sign of green. Pick off as many berries as desired. Each berry contains one seed.

Lay the berries on a dish and smash them with the back of a spoon to remove the inner seed. After all of the berries are smashed, scoop them up and place them into a strainer. Hold the strainer under a gentle stream of running water to remove any additional pulp.

Fill a bowl half full of water and place all of the black mondo grass seeds into it. Allow the seed to soak for 24 hours. Pour the seeds through a strainer to discard the water and place them back into the bowl. Refill the bowl with water and allow them to sit for an additional 24 hours. Repeat the water changing process for at least three days.

Fill an unsegmented seed tray three-fourths full of a sterile compost mixture.

Place the black mondo grass seeds on top of the soil, spacing them at 1-inch intervals. Cover the seeds with another 1/4-inch layer of compost.

Water the soil until the compost is saturated and then place a piece of clear plastic wrap on top of the tray to prevent the water from evaporating.

Place the tray in a brightly lit location but not in direct sunlight. Check the compost once per week and add additional water, if needed, to prevent it from drying out.
