How to Split Pampas Grass


Pampas grass is a native ornamental grass of South America. The grass grows to heights of 12 feet. During the summer the blooms sprout a foot above the foliage and remain until winter. The color of the blooms depends upon the variety of pampas grass growing. The grass is rough and hard, causing abrasions on the skin when you come in contact with the blades.

Step 1

Put on protective eye-wear and gloves before working with the pampas grass. In early spring or late fall, cut back the pampas grass using pruning shears or a sharp knife. Leave 3 to 4 inches of grass exposed. Add the grass blades to the compost pile but do not add the plumes, which contain seeds.

Step 2

Dig up the root ball of the pampas grass. Remove any side shoots from the root ball for planting in another area that receives full sun.

Step 3

Cut the root ball into three equal sections by inserting the knife directly into the middle of the roots and cutting a wedge using a sawing motion. Repeat the cut with the remaining section of roots.

Step 4

Add compost or other organic matter to the existing hole where the pampas grass is planted. Replant one section of the pampas grass at the same level as previously planted. Water generously at first planting and continue watering each day until the grass establishes itself.

Step 5

Dig a hole for the other two sections of pampas grass wide enough to allow the roots to spread. Make the depth of the hole the same depth as the grass was planted before division. Add compost around the newly planted grass. Water thoroughly and water every day until the divisions establish themselves in the garden.
