I'd love some. Mine disappeared as soon as I added goldfish. Yum.

I am surprised your fish/wildlife aren't eating it. As soon as I add it to my pond, its gone in a matter of days as my fish love it.

In hot humid Florida duckweed will strangle your pond in a single season. Leaving it be will Kill the pond. My pond has been full of grass carp for the 20 years I've owned this property. The carp sure didn't stop the duckweed from taking over the pond the past few months. The ducks can't handle it either. I don't know anyone in central Fla that wants duckweed in their pond. Hillsborough county has a video on YouTube on how to get rid of it. There are several other videos also-we just don't have the manual/mechanical resources right now. There are some chemicals that are theoretically safe for wildlife. We've got a pro working up an estimate. the duckweed grew way faster than the dozens of grass carp that reside here can eat it. From what I understand it's not their preference but will eat it if there is not much of a choice. I was floored when I learned people buy this stuff. C'mon down, it's free. We did get a price on dredging the pond... $20K. Ha! Chances are it's the silt that's providing the nutrient that's caused the bloom

cedrbp,

Go on Ebay and put in live duck weed for sale. You will be surprised at how it sells.

I would buy some more, you would probably sell so much of it, you will be shocked. Especially now, everyone is setting up ponds, adding fish, they will want it.

Just a thought.

No one in Florida wants duckweed. Nothing personal at all, but I don't want to use my pond as a duckweed farm. I want to have an inviting clear pond that will be an attractive feature for renters. The porch overlooks it and duckweed covering the half acre body of water choking out the ecosystem that lives within it is unattractive. It looks like a disgusting green swamp. It is not worth my time to engage in such a tedious exercise as scooping up a nuisance weed that yields such a dismal return. You are not aware of the problem it creates inI Florida. Duckweed removal/control is an industry for a reason.

It makes great mulch/fertilizer. Here in Oregon we have to buy duckweed for our ponds and I am always thrilled when a bit winters over. Sorry you are so over run with it :(

update: the duckweed started to diminish (by about 1/2) even before we've had a chance to deal with it... but then another disaster struck. about 7 days ago a greenish powdery film that kind of looks like pollen started forming. i know what pollen looks like floating on the top, its yellow and disappears in a week. this stuff is getting thicker every day and now there are bubbles on the surface everywhere. as i've mentioned, there is a tremendous amount of silt on the bottom of the pond which is a 1/2 acre natural pond, spring fed and full of grass carp, small bass and a few other types. soft shell and snapping turtles live in it as well as a 4 ft gator. i can only imagine that the decaying muck/silt is responsible. the "lake doctor" said it would cost $20K to dredge it. that's out of the question. anyone have any idea what this green stuff is? its not like the algae blooms we've had in the past. those look like clumps of slimy green fuzz. this ain't that.

A pond with a 4 foot (and growing) alligator would be an attractive feature for renters?

Never been a problem. 6 sets of tenants across 20 years and no one has ever cared or had an issue. The gators come and go. One will move in at about 2 ft and they typically move on to a larger body of water, such as lake Jesup, at about 4-5 feet. There is no such thing as a body of fresh water in Florida that does not have a gator. The "problem gators" are ones that have been fed by humans. same with the bears.

I have BUY duckweed up here in zone 6 and I have to go to New Jersey! They charge about $5 per portion and I assure you it is not a generous sized one. Sheesh.

there are different varieites of duckweed. the stuff people buy for
their koi ponds is tiny and bright green. the stuff in my pond is
brownish green with larger leaves, relatively speaking.

giant duckweed

i
understand that in asian cultures people eat it as well. ounce for
ounce more protein than soy beans. people also eat spirulina and blue
green algae. it costs a lot too, but i still don't want it in my pond. oh the irony!

Maybe you have Azolla? https://en.m.wikipedia.org/wiki/Azolla#/media/File%3ACanning_rv_azolla_02_gnangarra.jpg

Not that it matters, I suppose. That costs $5 per portion up here, too.

that's the free market at work! scarcity sets the price. its worth $0 down here.

azolla is a fern - or at least has fern-like leaves. we definitely have duck weed, there is no mistake. i have pics, but not on my laptop where i'm typing this now. its so incredibly common in florida. i have another pond on my property that has always been covered in duckweed. can't see the water. it has no flow, boils feed it fresh water but not an actual spring like my nice pond. the boils are the only reason its not dead. i don't care about that pond because its on the back part of the property and surrounded by woods. about 8 of my 10 acres are undeveloped.

as i mentioned earlier, duckweed removal is an entire industry. while small amounts of duckweed are a sign of a healthy pond, once it covers the pond - the pond's survival is at risk. imagine not being able to tell there is water in the pond because the duckweed is so dense it looks like someone tossed a brown/green tarp over it. you don't want that.

on an upbeat note, the green coating is disappearing. based on my research i think its a type of algae that breaks down on its own. my husband went out in the canoe and stirred it up real good and the water is clearing up. i think i'm about settled on treating the duckweed with fluridone and keep the algae at bay with Orb-3 Lake & Pond Enzymes. anyone have any experience with either or those? the duckweed is starting to diminish which is good, but it can easily get out of control again.
