Cane grass scourge

[tada]

My theory is to wackem just just before they start to seed. Then each time it rains again wait about a week when they inevitably reappear wack them again. So as to prevent the millions of seeds to disperse. After a few months the wall of green get sparse???


I am on the Leeward side where there's distinct intervals between rainfalls so might be like playing wacka mole on other side. But might get rid of the scourge faster due to frequent regeneration on the rainy side.
