Brush Hogging Cogon Grass. Advice and guidance needed.

Like etpm - never heard of Cogon grass. From what I've read - pretty nasty stuff. I don't use pesticides or herbicides.

I could make an exception........

Sorry I am unfamiliar with that grass, but steel blades swinging at 15k fpm should cut just about anything. Is the tractor/mower laying it down and it just isnt coming back up to be cut?

I too am unfamiliar with that grass but then I don't know grasses to me grass is that green stuff I have to take time from other things to cut. However I do know that several years back we ended up with some kind of grass (was told it was goose grass, whatever that is) that even with fresh blades razor sharp it would not cut, it would just shred it off like you were trying to cut with extremely worn out blades. Between Roundup and reseeding we finally got it beat.

Cogon grass has high silica which dulls blades.

Glad I don't have it around where I live, but in certain areas of the US, I've heard it is nothing but a pain.

For ROW stuff, it is sprayed, but with a more aggressive herbicide than Glysophate. For small scale, spray/burn/dig; and respray on first sign of fresh growth. It's like tropical soda apple and many others; if you get it early, it's easier; but in the end, you treat everything that comes up, eventually the root structure dies. I dont think it typically spreads primarily by seed, mostly by runners.

Cogon grass sound a whole lot like the Horse Tail grass we have around here. Very high silica content. Tough on mower blades.
