Ornamental grasses look great in any garden. They add interesting colors and textures. However, there are varieties of ornamental grasses that should only be grown in containers. Spreading varieties of ornamental grasses can be invasive if planted in the ground, so it's best to keep them container bound. Planting ornamental grasses in containers does not distract from their beauty as long as you choose the proper size.
Choose ornamental grasses that grow well in a container and in your climate zone. If you are willing to move the container indoors in bad weather, you can plant ornamental grasses in containers that do not grow well in your climate.
Prepare a container large enough for the ornamental grasses, which will most likely spread out in the pot. Also, make sure you use a container that drains well.
Plant ornamental grasses in the container in the early spring for cold-season grasses and early summer for warm-season grasses. This will allow the grasses to establish themselves.
Dig a hole for the ornamental grasses to accommodate the root ball, about 6 to 8 inches deep and 6 inches wide.
Place the root ball in the hole and cover with potting soil. Water your ornamental grasses right away. Allow the water to soak in.
