How to Care for Pink Pampas Grass


With its impressive clumps of tall foliage and silvery pink plumes bending gracefully with the breeze, pink pampas grass (Cortaderia selloana) makes a dramatic mark on the landscape. Native to Argentina, Chile and Brazil, pink pampas grass makes a good windbreak when planted in groups and will stabilize the soil on difficult slopes. As lovely as it is, pink pampas grass isn't always suitable in the home landscape, as the plant can grow to widths of 10 feet very quickly. Pink pampas grass is hardy in USDA Zones 8 through 11.

Step 1

Plant pink pampas grass in full sunlight and well-drained soil. Although pampas grass will grow in nearly any soil type, the plant won't tolerate soggy soil.

Step 2

Water pampas grass immediately after planting and keep the soil moist for the first two to three months. After that time, give the plant about an inch of water every week during warm, dry weather.

Step 3

Prune pink pampas grass every year in late winter before new growth begins. Use hedge shears, hand shears or power pruners to cut the plant down nearly 3 or 4 inches in length. Prune large plants with a chain saw.

Step 4

Scatter a light application of a balanced granular fertilizer around the plant every year, immediately after pruning. Use a balanced fertilizer such as 10-10-10 applied according to the manufacturer's recommendations.

Step 5

Divide pink pampas grass in early spring every three or four years to prevent the middle of the plant from becoming old and unproductive. Separate the healthy young growth on the outer edge of the plant with a shovel, ax or hand saw. Replant the divided sections immediately and don't allow the roots to dry out.

Tips and Warnings

  • Wear full-length pants, long-sleeved shirt and gloves when pruning pink pampas grass, as the blades can be sharp enough to cut skin. Because of the sharp blades, avoid planting pink pampas grass near areas where children play.
