water grass mulch?

[Tropheus76]

As most people from FL can tell you, we have a problem with invasive water grass in our canals and lakes. I know seaweed works well providing nutrients and such as it breaks down. Would freshly harvested freshwater grass work as a mulch as well? Some of us could literally get more than we could ever use.

should be fine.

It will probably melt down into nothing in a few days or weeks. Wood chips will not. Water grass might provide a good range of minerals but not much bio-mass.

I agree with Zands, but I still think it's worthwhile using. I get a lot of algae and waterplants (from my own place) that I use for mulch and whatever nutrients that are in them. I also use woodchip. Waterplants do dry down to less bulk than when fresh, but there's still a lot of organic matter there. If you want more biomass, and there's plenty of water grass, just use more. But don't let it pack down into an anaerobic mess. That's where my woodchip helps.

Oh yeah, it was more of an idea for natural mineral import than true mulch. I also use fresh woodchips from the tree cutter people.
