My wildlife pond has got a lot of duckweed. Normally I just scoop it out with a net but I notice a fair amount below the surface as well.
Is there a treatment available which rids the pond of this without adverse effects on other pond life?

When I had a pond, I used to roll it up around a cane. It worked.

I put Barley straw in my pond, it not only keeps the blanket weed away but it keeps duck weed under control too. The barley straw has to rot to have any effect, if you put it in now you won't see results for about six months.
As the weather warms up the duck weed will come back to the surface, it sinks down for winter protection.

It don't half pen and ink after it has been there a while. not sure how effective it was but the main fish pond is crystal clear atm The wildlife pond has no pump or filter and is left very much to its own devices but I will get some barley straw bundles and try that. Thank you both. |

I got a childs fishing net last year and kept scooping it out, doesn't get rid of all of it, but it did keep it under control. (the child is still crying ;D)

Get a duck?  Seriously I've observed some wild ducks eating the duckweed at a fishpond. The owner raises tilapia in his fishponds and the fish are voracious consumers of duckweed. He even has to grow duckweed and azolla in different ponds to keep up with the fishes appetites. Oh and hubby said he used to grow catfish and observed that they eat duckweed, well they eat everything else so it's nothing new I guess. |

I was going to say that Cherry is confused between duckweed and blanket weed but Sweetpea has beat me to it.

I'm not aware of any control methods other than scooping. the blinking stuff even survived last winter frozen soild for 3 weeks.
