I live in a subtropical area and use vetiver for erosion control. The great thing about many of the tropical trees, such as Moringa, is that they can be started by branch cuttings. I am currently experimenting with optimum length, but so far the cutting placed in water began creating roots in less than a week. Then I transplanted some to soil.
My question is that the leech field downgradient of the septic system in question is really steep and then there is a smallish patch of non-construction bamboo, then a stream. Recent grading of an access road has caused septic water to come out of the embankment and running above ground. So we are trying to find a plant mix that would clean up the septic water before reaching the stream. What are some solid tropical/subtropical plants or what kind of root structure should we be searching for to best clean up the septic before it reaches the stream.
Thanks!
