Duck weed hell

[Marb67]

I did a very silly thing 4 years ago when I made my pond. I decided to get a little bit of duck weed from the wild along with other native plants. I can say it's the biggest regret of my pond life because it covers the whole pond and I just can't get the better of it. I fish it out using a baking sieve which is great but I have to painstakingly make sure that tadpoles and those small shrimpy creatures don't get pulled out with it. The pond is only small but I can say after an hour's session of filtering the stuff out I had hardly made a dent only to find next day the whole pond was covered over again.

The only plus side of this is it makes great green manure/compost fodder

Never tried it- but have a look at this- it claims to be natural.

Wait until you have a good thick layer it's easier as it all clings together. Strain it out and leave it in a heap on the side of the pond over night. All the little creepy crawlies will find their way back into the pond by themselves.

I am afraid you will never get rid of it just keep it under control and it will provide shade to the pond and possibly help to prevent algae.

I actually was daft enough to BUY some from a garden centre about 20 years ago!

And yup- you just sieve it out and leave it in the shade at the side of the pond for easy access of the wild life back into the pond.
Yup- some pondlife will die and some will be eaten by the birds, but apart from starting afresh ( had you thought of doing that if it's small??) it's the only other alternative.

Or maybe try that link I just posted????

We made a wildlife pond on our site last year. It's big and at the bottom of the field's French drain. I think all the fertilisers we use also wash down and the pond has been covered in weed all year. Every other week it is fished out and left on the side. It is annoying, but like you say, it makes good compost.

There are chemical treatments available. Depends how you feel about it.

I planted a very young mulberry tree near where my pond is now, it was obviously very unhappy- not growing and with shrivelled curled leaves. I fished out the duck weed and started putting it around tree after I had left it by the pond to give any wriggly a chance to return. To my surprise the tree grew a foot and now has lovely glossy leaves. It may be a coincidence but the transformation has been so incredible that I am experimenting with putting it around other plants.

Hello Marb, I have just read an artical in the Gar. News which says that duckweed is the new supperfood, as it contains 60-70% protein, so if you have a pond full of it, you have a head start on the rest of us, and sure as anything once you start trying to grow it for food, it will die off.
Keep removing it from your pond and place it on a piece of poly. to allow the insects etc. to get back into the water.

I have so much algae, i dream of having duck weed! Yes, I know, I'd regret if I did have it

[Verinda]

I have so much duckweed it gives me nightmares...it didn't occur to me I should be eating it!

....duckweed stir fry??

You must be quackers.

Shade and Barley straw or Barley straw extract should help.

The more sun the Duck weed gets the faster it spreads.

Maybe try and get some plant life that offers shade and covers the surface more to help control the duckweed and is nicer to look at?
