Duckweed, or water lens , is a family of small flowing plants that float on the surface ponds and lakes, similar to water lilies. Unlike algae , which compromise a group of photosynthesizing micro-organisms, duckweed is an actual plant and can have similar benefits to ponds that come from regular aquatic plants.

For this reason, so long as duckweed is not allowed to become invasive and take over the entire pond, small levels are usually left alone as they provide extra water filtration by making use of extra nutrients. Duckweed also provides a good snack for goldfish and koi; with goldfish in particular being very fond of the taste!

Even so, duckweed is notorious for its fast spreading capabilities under the right conditions, and can quickly become dangerous, especially in small ponds with fish. If levels are allowed to get too high the duckweed will begin to reduce oxygen levels and contribute to an increase in waste, sludge, and harmful substance build-up.

If you find a sudden duckweed bloom it could be a sign of a growing water quality problem that requires further investigation. Often duckweed is carried to a pond by birds or other animals; starting as a small floating seed which is very difficult to identity until it grows.

Once a single instance of duckweed has been introduced to a pond it can quickly spread under the right conditions, so the best time to remove duckweed is as soon as you see the first few sprouts appear. Duckweed can also be carried with other aquatic plants you purchase, usually hidden away among the foliage or within substrate.

Duckweed and blanket weed are often mixed up, with duckweed being a plant and blanket weed being a form of algae. Blanket weed is often seen during summer when algae blooms are common, and usually grows alongside more common forms of algae, such as green pea soup algae.

Unfortunately, blanket weed is far more difficult to remove in comparison to duck weed, especially if nutrient levels are high and weather conditions are right. If you do happen to have duckweed in your pond, it can actually help with the removal of blanket weed and other alage as it directly competes with them for nutrients and sunlight. Sometimes leaving a little duck weed during summer can help with algae control, especially in areas of intense sunlight.

For more information on blanket weed and how to remove it, along with algae in general, check our full guide on this here. Small amounts of duckweed may be beneficial as they can help reduce excess nutrients, control algae growth, improve oxygen levels, and even provide shade and predator protection.

The problem with duckweed is that is can be difficult to maintain, and if your pond is already very high in nutrients or has problems with water quality, it can spread at lightening speed. Unless you simply hate the look of duckweed on your pond, the only reason you would need to remove it is if the duckweed is growing too fast and causing issues with water conditions.

This is especially true in ponds with fish, as excess duckweed can actually reduce oxygen levels and cause harmful spikes in ammonia. As duckweed grows a similar amount will die off, and as beneficial bacteria work to break down the decomposing matter they consume large amounts of oxygen from the water.

If the amount of decaying matter becomes too much for the biological filtration, ammonia and nitrites levels will spike, and oxygen will continue to be reduced until waste is removed. Keeping a small amount of plants, which includes even duckweed, can be beneficial to fish as it provides shelter and helps reduce excess nutrients from water.

If you have a pond with goldfish and koi, duckweed should never be allowed to spread uncontrolled across the entire pond. One of the easiest methods of removing duckweed is with chemical herbicides, which destroy the plants at the cellular level.

We would only recommend treatment with a herbicide as a last resort, and we do not ever recommend them for fish stocked ponds as the risk of fish death will always be very high. Never use on ponds with fish! For ponds without fish, they can be a easy and quick fix to remove duckweed, but we still strongly urge the methods below instead which help remove duckweed without chemicals. Be careful, however, as any plants you have will also be damaged so it should always be a last resort for all kinds of ponds!

If you have a growing duckweed problem, you may also have an underlying issue with water quality which needs to be investigated.

For example, if your pond has insufficient filtration or excess waste there may be a build-up of substances and nutrients contributing to the duckweeds rapid growth. Testing water quality if you have fish is an important aspect of fish keeping, and should be carried out at least twice a year, or at the first sign of problems. If the duckweed is spreading across the pond daily, you should test your water with a wide-range water test kit to make sure substance levels are within safe parameters.

The main things to look out for when testing are: ammonia, nitrites, and nitrates and phosphates. The first two are indications of insufficient filtration and can become very dangerous to fish in high doses. The latter two, nitrates and phosphates, act as natural plant fertilizers and will be readily taken up by any duckweed present in the pond. For more information on water testing and what can be done, you can read our full guide on this here. This guide includes all the information you need to reduce levels of harmful substances and how to test water correctly for the most accurate results.

It may not be the easiest option, but the best way to remove the majority of duckweed from ponds, especially those with fish, is to simply remove it manually with a strong net or vacuum cleaner. Unlike algae, which comes in many forms and can hide throughout the entire pond, duckweed will always be clearly visible on the surface water — making it easy to net out!

This also gives you full control over cleaning, and allows you to leave a little behind if you want to keep the beneficial aspects that come with small amounts of plants.

This method works best for smaller ponds, but can also be fine for larger ponds if your water quality is brought back into check. Usually duckweed will not be able to grow fast enough to require constant clean-up if water quality is good.

Testing water beforehand, and improving conditions alongside manually removing the duckweed, is the best method for control and safe fish keeping. If you have only a small duck weed problem, using a good quality net should be sufficient to clean out most of the weeds. After you have removed most of the visible duckweed, you can the move on to Step 3 and apply a natural duckweed killer to the pond, which will ensure the maximum amount of weeds are removed.

Natural duckweed treatments are basically a mix of beneficial pond bacteria which helps reduce nutrient content in the pond and starve algae and duckweed of what hey need to grow. After a big duckweed clean out, adding a natural duckweed remover may be enough to stop the remaining duckweed from spreading, but we still recommend you keep on top of any further growth manually until both water quality and nutrients are in good order.

If you have fish in your pond, either goldfish or koi, you can try reducing their feeding doses which will encourage them to eat more of the duckweed. Many ponds with heavy fish stocks will never see problems with duckweed as the fish will eat it faster than it can grow, but if you like to feed your fish regularly they may just be too full to help out.

If you have a gradually growing duckweed problem, you can try reducing feeding to every other day to increase the amount of weeds eaten by fish. Top quality fish foods will have lower filler content ash and high content that fish actually need proteins, fats, minerals etc.

For a full guide to the top fish feeds, check our dedicated article here. We recommend a few things to keep on top of excess waste and nutrient levels in ponds, all of which can be incorporated for maximum results:.

I had a small wildlife pond which each summer became absolutely choked with duckweed. Eventually I used a different bio control agent, bought from a London-based company that sells a wide range of biological controls for ponds. It was in the form of a white powder, and my understanding is that it is bacterial and that it sequesters nutrients, thus killing duckweed.

Well, it completely killed all the duckweed and everything else. It carried a warning that it could affect aquatic plants. This was an understatement. Two years later, I still have a completely dead pond. I drained it last year, and relined it, but the new pond was infected too — as it only takes a drop of infected water to completely colonise a new pond or even a bucket containing pondweed.

Birds can carry infected water on their feathers. I had bought a first-rate biohazard. I am now facing the prospect of having to completely drain and disinfect the new pond. This can be achieved used hydrogen peroxide, but in quantity this is very expensive. So, be warned, some biological agents can be immensely destructive. The whole disaster has been extremely costly on time, money and emotionally too.

Even soil into which the original infected pond water was poured 12 months ago can still infect water and destroy all aquatic vegetation I have set up a large number of experimental containers with fresh elodea as test vessels. If you see a product that says it affects other aquatic plants, my suggestion is, do not buy it. If you are tempted to do so ie if duckweed is driving you mad , then please use it first in a test bucket and put netting over it to stop birds from transferring the solution elsewhere.

Your advice is sound, and I totally agree with you — as with any product which affects the eco-system or wildlife, always read the label, perform additional research, and just be extra diligent in your approach. Testing new solutions in a separate bucket to ensure there are no ill-effects is also great idea! Kudos to you for not wanting to disturb the newts!

Any duckweed that is sinking is likely either dead or dying, and should be removed promptly. Decaying matter will use up precious oxygen in your pond while also adding to the nutrient load and potentially encouraging algal and bacterial growth that could harm fish or even newts.

If your water has excess nutrients and organic pollutants via decaying plant matter, that means their bodies will absorb some of this. Just do so carefully so as to not accidentally scoop up any newts! I find a good way to reduce duck weed is to wait for a frost, then lift out the newly formed ice sheet with all the weed trapped inside. Yes I found that too. I have one tiny pond which we sorted last year and the newts and frogs are still in there, plus spotted a small grass snake in it last year.

However top pond has so much duckweed, and still needs sorting as it has a leak. Problem is today we have frogspawn!! What can we do!!!! That is wonderful that you have newts, frogs, and a small grass snake! Those are wonderful additions to wildlife ponds. This site uses Akismet to reduce spam.

Is Duckweed Similar to Blanket Weed? Small amounts of duckweed can be beneficial to fish ponds, and goldfish love to eat it as a snack.

Herbicides will remove duckweed quickly, but are NOT recommended for ponds with fish. Step 3: Apply Natural Duckweed Killer Natural duckweed treatments make use of bacteria to help starve duckweed of nutrients. Step 4: Reduce Fish Feeding Pond fish will happily eat duckweed, but you may need to reduce normal feeding to encourage it. Hi Shona, Kudos to you for not wanting to disturb the newts! Hi Kimm, An interesting and useful tactic — thank you for sharing! Hi Val, That is wonderful that you have newts, frogs, and a small grass snake!

In terms of frogspawn, do you mean tadpoles, or the invasive plant species European frogbit? What about adding goldfish to your farm pond to eat the duckweed? Hi Greg, Also a good strategy!
