Executing the Annual Spring Prune


Appropriate equipment and attire are required for a thorough prune. Long-sleeved clothing, cut-resistant gloves, and safety goggles are recommended to protect against the sharp leaves. Instead of trimmers, opt for a chainsaw or long-handled pruner to handle the task.

Pruning Steps

  • Before you start, inspect the base of the pampas grass for any animals that may be hiding.
  • Cut the leaves close to the base, leaving a tuft of branches approximately 5 inches high.
  • Work in sections to make the process more manageable.
  • Apply a suitable fertilizer to facilitate recovery and healthy growth.
  • Be careful to avoid damaging new shoots during the pruning process.

Thinning the Cluster

Every 2 to 3 years, a thinning of the pampas grass cluster is recommended. The plant typically has a main cluster with smaller ones emerging from it. These smaller clusters should be removed to maintain the shape of the main one and control the plant's growth. This thinning can be done concurrently with the annual pruning. To separate the roots of the clusters, an axe or saw may be needed.
