Cutting back huge clumps of miscanthus
I have five huge clumps of miscanthus sinensis. Sorry I'm not sure of the exact variety. I think it's the silberfeder. The clumps are something between 3 and 4 feet in diameter at ground level.
In the past I have used all of these to cut it back: large lopping shears, electric hedge trimmer and chain saw. I simply am not able physically to do the lopping shear method anymore.
The electric tools will cut okay, but the housings constantly get jammed full of dried grass stems. I have to stop every few minutes to laboriously prod it all out.
Has anyone else found a better method/tool for cutting these grasses back? The time to do it is coming near and I'd like a fairly fast way to do it. The job of gathering and disposing of the mass of cut stems alone is a major one without having to take all day to do the cutting.
Any advice would be much appreciated.
