To stop further collapsing of a pond bank, vetiver plug can be planted 6 inches above the water level. Fully grown vetiver grass can withstand a partial submerged in the water without any problem. Fully established, vetiver line will perform as a living wall to slow down run-off rain water into a pond. The root system will form a matted wall to strongly hold soil of a pond bank. No further collapsing bank after 2-3 months after installation. Guaranteed.
