Best time and way to use Roundup on Eulalia

mishko_2006June 5, 2006

I am going to use Roundup to spray my invasive Japanese Silver grass (eulalia ???). It has already grown to large clumps some 4 feet tall. It's a real nuisance!!

I read somewhere that I should wait till it's about to flower for the best results.

I'm afraid I'll have too much of it over a large area if I wait till then as it flowers in August or Sept here in Korea. Should I go ahead now?

2nd (related) question. Should I cut down the leaves with my bushwhacker before spraying with Roundup? Or is it better to spray the complete undisturbed plant?

Thanks for your advice!

Your Ornamental grass is Miscanthis sinensis.
You will need to kill the entire root system to completely stop it.
Here is some info last paragraph

Thanks very much Vera. I'll let you know how it goes, having tried Roundup on both cut and uncut plants, now and in fall if necessary!
