Propagation of Japanese forest grass is best done through division, a process that's surprisingly easy. You'll want to dig up the entire clump with a shovel in the spring, when new growth is just beginning.

To divide the clump, use a spade or garden knife to separate it into three or four sections, each with a healthy group of roots and some active shoots. This will give you the best chance of successful propagation.

If you're using Japanese forest grass as a ground cover, make sure to plant the sections 18 to 24 inches apart. This will give the plants enough room to spread out and thrive.

Propagating is an essential part of gardening, and it's great that you're interested in learning more about it. Japanese forest grass is one type of plant that can be easily propagated by division, but it's essential to do it at the right time.

Potting and repotting is an essential part of plant care.

Choose a pot with large drainage holes to prevent waterlogged soil.

Fill the pot with rich, well-draining potting soil to give your plants a healthy start.

Place the pot in a shady spot that receives some dappled light.

Potted plants need more frequent watering, especially in hot conditions, up to daily in some cases.

Some plants, like Japanese forest grass, benefit from a monthly feeding with diluted fertilizer to replenish lost nutrients.
