How to Cut Back Pampas Grass for Healthy Regrowth

Poplars are often planted in rows.

Overview

Pampas grass (Cortaderia selloana) provides three-season texture with green summer blades that turn golden in winter. Proper pruning requires understanding its growth habit and heavy-duty tools for thick foliage.

Step 1: Winter Preparation

Allow foliage to die back naturally for winter interest. Tie twine around the clump at 6-inch intervals to prevent heavy blades from flopping.

Step 2: Timing

Prune in late winter before new shoots emerge. Removing dead material lets light penetrate the crown, stimulating fresh growth.

Step 3: Bundle & Secure

If not already tied, gather all blades and wrap twine around the entire clump. Trim loose ends to avoid snagging on cutting tools.

Step 4: Cut Back

Wear gloves—blades are razor-sharp. Using loppers (or a chainsaw for large clumps), shear dead foliage straight across to 6 inches above ground, like a buzz cut.

Step 5: Clean Out Debris

Run gloved hands through the center to remove remaining dead material. Goal: open the crown to light for vigorous new shoots.
