Ray picked this up on another post as I am currently trying to recover the grass that exists in the garden at my in-laws primarily to maintain moisture in the ground but also to cut down on the dust flying around in the air. Either way Ray mentioned Bermuda grass would be a good alternative and after reading up on it makes perfect sense as its also a herbal plant as well as offers the ground cover I want with low quantities of water required.
The other thing I like about it is it can survive extensive droughts and flooding which with the Wet and Rainy seasons in the Philippines makes it perfect for covering the ground. On the negative side it can act as host to some diseases such as brown spot, leaf spot, early blight, stripe disease of rice, barley yellow dwarf, lucerne dwarf, and of nematodes. So worth checking if its any good for your area but where I am looking it can’t do too much damage as most of the ground has turned to dust already and only a couple of banana plants exist.
