Pampas grass can be difficult to trim back. The leaves are razor sharp, necessitating the use of protective clothing and garden gloves. Some gardeners advocate burning the grass to the ground and allowing the plants to spring back from the roots in the next growing cycle. However, if you are determined to cut back pampas grass, there are a few tools that can help you.
Hand-operated hedge clippers are a low-tech way to deal with pampas grass. To protect yourself from the sharp leaves of the grass it is recommended to wear protective gloves, a long-sleeved shirt, pants and goggles. It is best to avoid wearing sandals or other open-toed shoes while trimming pampas grass with hedge clippers.
Electric Hedge Trimmers
Mid-sized or industrial-strength electric hedge trimmers are powerful enough to cut through pampas grass without binding or seizing up. Additionally, these types of trimmers are often simpler to use than hand shears.
Some gardening companies manufacture circular saw blades to attach to string trimmers for trimming tough grasses such as pampas grass. Using these types of tools require the same attention and care as a chain saw. To use a tool such as this to cut pampas grass, bind the grass into sheaves, and cut the bases with the saw.
Although a chain saw is designed for cutting woody plants such as trees and large vines, it can be used to cut back pampas grass. To use a chain saw, first bind the grass into sheaves to make the cutting surface uniform. Then only cut using the top of the chain and bar section of the saw. This will prevent the chain saw from dragging particles of grass into the machinery.
