  • Grows Rapidly – Seagrass grows back rapidly; it is one of the fastest-growing plants. The cutting and the harvesting of Seagrass does not damage marine life because the plant will grow back very fast.
  • Marine Food – Many Marine life and species depend upon Seagrass. Seagrass is an essential part of the entire marine ecosystem. That is also why when Seagrass is cut here in Vietnam, it is only cut in certain areas, and those that are harvesting the seagrass are very careful not to damage the marine or sea life.

Seagrass is not the same as Seaweed; both were very different plants. The only thing that Seagrass and Seaweed have in common is they both use the name Sea in their names, and both grow underwater. 

Seagrass and Seaweed have different uses; one is used mainly for food, and the other is used to weave baskets such as home decor baskets or other home decor accessories.
