Blanketweed gives way to vasculars that grab nutrients more
effectively. Our berm ponds (veggie filters) have blanketweed now and
are developing a better cover of hyacinth. The blanketweed will fade
away...rot...as the hyacinth grow.

Our main pond has no blanketweed...the koi think of it as a snack!
That also works!

More plants or more weedeating fish.
