Ornamental grass is beautiful in a small space garden. In the photo above, I planted pineapple sage with ornamental grass in a contrasting color behind it for vertical interest.

Most grasses are pretty much self-sufficient. Potted plants need to be watered deeply and less frequently. Allow the pot to dry out between watering unless you are growing a water loving species or marginal grass.
Every two years remove the plant from the pot, replace the soil mix and divide the grass. Cut the plant into two pieces. Then replant each piece separately.
Ornamental grass care for containers includes pulling out the dead blades.
Some grasses will die back in winter and the blades will turn brown. You can leave them until early spring and then cut them back to a couple of inches from the crown.
Brand new blades should grow and fill in the plant as spring progresses.
Ornamental grass thrives in an area that gets at least 5-6 hours of sunlight daily.
You need a container that is deep enough for the plant to have room to spread and to support the root system. Make sure the bottom of the container has adequate drainage.
An excellent medium for ornamental grass is one part compost, one part top soil and one part perlite.
Different types of grass have different needs. But as a general rule water your ornamental grass container when the top two inches of soil is dry.
Fertilize annually in spring with sow release fertilizer.
