The Complete Guide to Duckweed in Ponds (Removal, Prevention & More)

In this comprehensive video, we dive into everything you need to know about managing duckweed (Lemnoideae) in your ponds effectively. Duckweed, a small floating aquatic plant, is a common issue faced by pond owners around the world. Its rapid growth and ability to cover the water surface can disrupt the balance of your pond ecosystem, impacting the health and aesthetics of your aquatic environment.
Removing and preventing duckweed is a primary focus of this guide. We'll delve into a range of methods to combat this nuisance weed, including physical removal techniques like raking, and biological control options, such as introducing natural predators, preventing waterfowl access and using our beneficial bacteria product, Envii Sludge Klear.
Throughout the video, Ash shares valuable tips, dos and don'ts, and troubleshooting advice.

Revisiting. The featured pond is fantastic. I hope the owners now see more of its contents.

I skim pond duckweed and put it in my compost bins which have a population of worms normally associated with a wormery. The worms love it.

[@danielvonbose557]

That's good cause I'm gonna try it to make vermicompost. I've had a population crash this summer, so I'm gonna try and get my population up. I will also be applying it mulch style to certain heavy feeders in the garden.

Thanks for the advice!

Thanks for the info from Texas

Very interesting video, cheers, I’ve got duckweed in my small wildlife pond and I scoop it out every few days which is a pain as I’ve got plants and rocks (for birds to land on to drink from the water) and it’s difficult to get the net in around.

[@petelongrs]

Good video. Would be better if we could see the effect of the added product.

[@moses9239]

Very impressive video. But I would like to ask what are the steps to setting up a duckweed farm? Does duckweed require any amount of manure? If yes then what is the best type of manure to be used? Tnx

[@enviipond]

Hi, thank you for watching. Unfortunately duckweed farms are beyond our scope of knowledge! We predominantly cover content on ponds. However, going off our general knowledge of gardening, manure will certainly benefit growth and any type of manure will work fine, just make sure the manure is well composted to reduce risk of ammonia toxicity!

I have actually tried to introduce duckweed into my small garden pond for some years but every time I purchase some the fish devour the lot within days😢

[@Moamanly]

I'm mystified why people in UK think duckweed is a problem, Is is because you don't have as many hours of sunlight in a year perhaps as other countries? Here in NZ we need surface plants to cover 60--70% of the pond to prevent algal blooms. It is drawing nutrients out of the water and provides a home for other creatures as well. Duckweed is like gold!

[@SherrickDuncan]

And it healthy is human food, animal feed and vegetable and fruit garden compost for growing food.

I love our duckweed here in the USA ☺️ Keeps the water clean 👍

[@shanemahabirsingh7215]

You didn't lock back the latch at the start. Now all the fish will get out

[@RayHampson]

What are airstones which are mentioned in the video?

[@enviipond]

Hi, thanks for watching. Air stones are essentially small pumps that can be added to a pond to circulate the water and increase oxygen levels. Hope this helps!

Try using barley straw it works

[@enviipond]

Hi, thanks for watching! Whilst barley straw is effective for some cases, we've always found beneficial bacteria to perform better. Whatever works for you though!

[@hotelsierra86]

What about barley straw?

[@enviipond]

We've always found that barley straw can work in some cases but not in others and can be fairly mixed in terms of results. But if it works for you, it's worth doing!

[@hotelsierra86]

@@enviipond I put three bales into my pond ten days ago but there is no improvement. Any idea how long they take to work? Thanks

[@enviipond]

@@hotelsierra86 It's most effective when you apply it as a prevention rather than cure. It can take anywhere from weeks to months before you see anything.
We recommend using beneficial bacteria or a specific algae treatment instead if you're struggling with that. Algae treatments can work within a week whereas bacterial treatments will be a similar timeline to barley straw but we've always found bacteria to be much more effective.
We have lots of pond blogs on our website that might be of use to you:

[@CarpMan34]

Guys the pond in my girlfriends parents garden probably about 5-6 times the size of this will this product clear the 2 ft of silt and sludge at the bottom of the pond and kill the duck weed ??

[@enviipond]

Hi, thank you for watching. Using Sludge Klear on a regular basis will certainly clear the silt and sludge at the bottom of the pond providing adequate amounts of the product are used. It will also starve the duckweed over time and reduce it. It won't target and kill the duckweed directly though, Sludge Klear targets only the nutrients that feed the duckweed.
Feel free to get in touch with us via email ([e-mail]) if you need more information. Thanks!

[@CarpMan34]

@enviipond sorry only more thing guys I have newts and a few golden rudd will they be OK with this .?

[@enviipond]

@@CarpMan34 Absolutely, Sludge Klear is completely safe for all fish and wildlife.
