Trimming of large grasses

katskan41April 4, 2009

Hi all. We have some very large ornamental grasses, not sure what species. It grows very tall (10 feet) and has dense and thick, bamboo-like stalks.

Any suggestions on the best way to cut these down? I've used pruners but that is a lot of work. Was thinking of using a machete or similar tool.

Rent a good gasoline powered hedge trimmer. It's like a chain saw motor with a hedge trimmer blade. A good quality (Echo) 20-24" trimmer will make fast work of any grass, but unless you have lots of grasses and hedges to trim, you probably can't justify the $300+ cost of purchase.

There are other, multi-use tools which can include a trimmer blade, which may be easier to justify owning, as you can use them for more than one task.

I've been able to cut my large miscanthus clumps with an electric hedge trimmer. I just work around the outer edge, removing canes as I cut toward the center. Sharp blade is key...and keep the cord out of the way!

I'd like to thank both donn and grass guy for their suggestions. My wife and I were able to cut down our grasses with an electric hedge trimmer. This worked very well. We used a bungee cord to tie up the grasses and hold them together then used the trimmer at the base. Took some time to cut down the largest grasses but it worked!

Thanks again for the great idea.

Now that you've cut them back, be sure to clean the crown of debris that can cause rot. Rake through with a stiff metal rake.

Sounds like you managed to avoid the cord while trimming...I won't go into why I mention that...:)
