How can I get rid of grubs and sugar cane beetles in a "green" way?
I would give neem oil a try. It is effective against other beetles and should work against this kind, both adults and grubs. It is organic and safe for people, pets and beneficial insects. Here is more information:

[from description of how 19th century slaves harvested sugar cane in Louisiana]: ..."The lead [field] hand, in the first place, with a blow of his knife shears the FLAGS from the stalk." So, what are these "flags"? Nothing I could find about sugar cane in general even used the word, never mind explain what, where located, these "flags" are. poor me....
Unfortunately, your photo did not come through.
Things that can cause these symptoms include high soil pH, low nitrogen content in the soil, over or underwatering, and many other pests and diseases.
In the meantime, Here is an article that will help to give them the proper care that they require:
Hi there, we’ve recently removed our lawn from the front yard. We were wondering if it would be doubly beneficial to put sugar cane down first and then pine bark over it. We previously had Sir Walter Buffalo grass and know that the grass will grow back. We want to use the bark simply because it looks nicer then sugar cane. We are wanting to plant different flowers and foliage. Is there any damage that can be done?
I don't see any reason that this would cause any damage. I think your idea would serve its purpose quite well, actually.
I planted my sugarcane about 8 months ago. It grew pretty well outside but when I moved it in the house for the winter it has not grown at all. I pruned it back and got ride of most shots and fertilized it. I water it Daily with 2 cups of water. What do I need to do?
It won't tolerate that much watering! At this point, the soil is likely infected with something. You can confirm by removing the plant and dumping the soil. It will, likely, smell of sulfur.
You will need a smaller container until the plant grows enough roots to transplant. Make sure that it is a container with holes that allows all water to exit into a saucer, which can be removed to prevent waterlogging the roots. Water, ONLY, when the soil has dried, thoroughly, down to about 3 or 4 inches.
Once it has filled the container, you can put it into a slightly larger one.
The lighting needs will, far, exceed what a window can provide, though. You will need extra horticultural lighting indoors.
