How to Grow Ornamental Grass in Containers

By Amy Hannaford ; Updated September 21, 2017

Grow ornamental grasses in containers for a low-maintenance, decorative look. Confining ornamental grasses to a container eliminates worries of them spreading and taking over your garden. Planting grasses in containers simplifies the task of dividing them in the fall, although they also become less hardy and may need to be grown as an annual or transplanted into a garden at the end of the season. Containers of ornamental grasses provide a nice change of pace from typical flower pots used to decorate a home's front entrance, patio or deck.

Select a large container at least 18 inches in diameter to allow the grass plenty of room to grow. Ornamental grasses can reach heights of 36 to 48 inches tall. Use a container with drainage holes in the bottom.

Fill the container halfway with a good quality potting soil, preferably one with peat moss added to increase drainage. Grasses generally prefer dry to moist conditions and do not like soggy soil.

Place the ornamental grass in the container, gently spreading out the roots. Fill in with more potting soil to within 1 inch of the rim of the container. Tamp down gently and water well.

Water the grass consistently with about 1 inch of water per week. Water when the top inch of soil dries out. To check the soil's moisture level, poke your finger into the soil down to your second knuckle.

Feed your grass weekly with a high-nitrogen fertilizer, such as a 10-5-5 fertilizer, which encourages abundant foliage growth. Use a liquid fertilizer for best results and water it in well after applying.

Set your grass in a sunny location where it will receive full sun for at least six to eight hours daily. For best results, plant in the spring, although grasses can be planted in the fall.
