I have phragmites in my pond, and they are so aggressive they even outgrow the cattails. What should I do?
Kandy – Portland, OR

Phragmites are the worst kind of uninvited guest: once it makes its appearance, it’s too late to give it the slip. For those who have experienced phragmites, they’ll attest to its tenacity. They’ll also attest to its heartiness. Unlike the plants you’re actually trying to grow in your pond, phragmites requires no care and feeding at all – and it’s remarkably adept at withstanding any effort to slow it down. .

Characterized by a green stalk with purple/tan plumes in late July, the majority of each phragmites plant is underground. As a result, by the time you actually see a phragmites plant in your pond, its root system is well established – laying the groundwork to take over the entire body of water. In fact, phragmites plants continue to spread throughout their life, sending stalks skyward at a blistering pace. And once the stalks reach maturity – typically from early to late summer – the plants double their efforts at pond domination by distributing seeds throughout the watershed. Phragmites, it seems, is quite capable at taking care of itself.

When taken alone, phragmites might actually be considered attractive. Unfortunately, it has no interest in sharing its turf. Through its aggressive growth, phragmites chokes out native plant species in short order, and can transform an entire pond’s flora over the course of a single season. And while it’s nearly impossible to eliminate phragmites once it’s established, our Shoreline Defense® & Treatment Booster™ PLUS Combo – carefully and regularly applied with our Specialty Pond Sprayer– can significantly impair root system growth, while leaving room for the plants you’d like to keep around.

After herbicides are applied, many pond owners are eager to eliminate both existing growth and dead stalks left over from the previous season. Our Aquactic Weed Cutter makes short work of offending plants. Once the cutting is done, our Pond & Beach Rake helps to remove mess. In some instances, pond users also use controlled burns – after herbicide application – to remove standing plants. While this can be effective, it should never be practiced apart from herbicide use. Some evidence suggests that burning alone – without the use of herbicides – can actually increase the density of phragmites plants.

Good luck with your battle against phragmites. Stay vigilant, stay focused, and act quickly to curb new growth. The fight may last a long time – but the results will be worth the effort.

How can I reduce algae growth in my pond? | Pond & Lakes Q&A

How can I reduce algae growth in my pond?

How can I reduce algae growth in my pond?
Ryan – Dallas, TX

As we progress through spring and into summer, it is important that you know how to treat algae growth should you experience an algae bloom. Persistent algae blooms will still flex their muscles even if you maintain a clean pond. There are really two approaches, a reactive approach-treating growth, and a proactive approach-treating the source.

Reactive Approach-Treating the Growth
You can provide a temporary relief from algae by treating these algae break-outs with an algaecide like Algae Defense® or Cutrine®-Plus Granular . It is best to treat the algae first, making contact between the chemical and the target algae as much as possible and then raking out the debris once dead. If the algae mat is more then an inch or two thick, you may want to rake out some of the algae before treating. To apply use a Pond Sprayer or Hand Spreader to kill off the remaining algae particulate. Once the treated algae dies and browns out, remove the debris with an Pond & Beach Rake so it does not sink the bottom of the pond and decay, encouraging new growth.

When selecting the type algaecide to use you will want to observe any use restrictions the product may carry. Algae Defense® and Cutrine®-Plus granular are a popular choice as they do not carry any water use restrictions. . These products do however contain chelated copper which will not harm the pond or most common gamefish but are not as friendly to trout if carbonate hardness is less than 50ppm. You can test your carbonate hardness before treatment with a carbonate hardness test kit. If Koi, Goldfish or Trout inhabit your pond and you are looking for another option you may want to consider using Clipper™. This product does carry some water use restrictions however it does not contain copper.

Proactive Approach-Treating the Source
Proactively treating your pond before you actually experience algae blooms can save you time and money in the long run. Algae blooms tend to be a symptom of a much larger problem – a dirty pond. By using only algaecides for pond maintenance you allow your pond to continue to accumulate organic debris and fuel for bigger and more stubborn outbreaks.
If your water temperatures are already around 50 degrees or above you can enlist the help of beneficial bacteria and natural water treatments to reduce organic debris and bind phosphates. Pond Logic® PondClear™ can be used to treat your entire water column and attack floating suspended organics that cause turbid water. Pond Logic® MuckAway™ sinks to the bottom of your pond to eliminate pond muck. Pond Logic® EcoBoost™ naturally binds the phosphates helps sink floating particulates to increase water clarity. EcoBoost™ also introduces trace minerals into your pond which improves the health of your game fish. Remember to also run your Airmax® Aeration System . Aerating your pond will ensure a healthy and well balanced pond for your fish during times of added stress while treating for algae, as well as to promote beneficial bacteria like PondClear™ to continue to breakdown any debris you may have missed while raking.

How do weeds like Cattails and Phragmites survive the winter? – Ponds & Lakes Q & A

How do weeds like Cattails and Phragmites survive the winter?

How do weeds like Cattails and Phragmites survive the winter?
Bryce – Grand Rapids, MN

Your gamefish and frogs aren’t the only ones hiding from the cold winter weather. Even your emergent weeds have developed a defense mechanism to survive over the winter. Being perennial plants, they may appear to die when the weather cools down but they are really just buying time until the spring thaw when they will return in all of their glory. Whether or not this is good news depends on how you feel about the presence of these particular plants in your pond.

Plants like Cattails tend to disperse their seeds as fall approaches. As the weather continues to cool the leaves and the stalk of the plant wilt and die only to decompose and become fertilizer for the roots, or rhizomes, of the plant come spring. While the exposed areas of the plant are dying off, the roots of the plant begin pulling in nutrients to store before going into dormancy for the winter. As these roots can be considered the heart of the plant, cutting down Cattail and Phragmite reeds will not discourage new plant growth in the spring.

If you like having Cattails or Phragmites around your pond then nothing is needed to help them through the winter as they are naturally prepared to make a comeback. If you are not a fan of these emergent plants you can make it harder for them to grow back by physically removing the plant roots or by using pond care products to remove their food source and kill the plants including the roots. Applying aquatic herbicides like Shoreline Defense® while Cattails and Phragmites are still active is infinitely easier than trying to pull their extensive root system from the pond. Shoreline Defense® is absorbed by the plant and carried to its roots effectively killing the entire weed. Since you don’t want to encourage new growth you will want to remove any potential “fertilizers” in the form of plant decay and muck. Once dead cut and drag any dead reeds and leaves away from the pond and burn or compost them. Using a Rake and Weed Cutter will make short work of these shoreline cleanups and give you the advantage for next season.

Rough Around the Edges?

As you’ve enjoyed your pond over the spring and summer, all of a sudden you begin to see that our pond have built what seems to be an impenetrable wall of Cattails and Phragmites. No worries! Emergent weeds won’t ruin your summer fun. Here are the right tools to get even!

Treating emergent weeds in your pond is a two step process. You will want to focus on dealing with your existing growth first. You can kill Cattails and shoreline grasses down to the root by spraying them directly with Shoreline Defense® . If you are dealing more with Phragmites, Water Primrose or Loosestrife then you will see better results using Shoreline Defense® & Treatment Booster™ PLUS Combo. Make sure you are spraying the plants when they are alive and actively growing so that the aquatic herbicide is carried throughout the plant’s root system. A Pond Sprayer is a great way to apply these aquatic herbicides. Also note if the emergent weed growth is very thick, a couple applications may be needed to gain complete control. Once you see all of the target weeds brown and wilt you can cut them down and drag them away with a Weed Cutter and Pond & Beach Rake.

Once the weeds are cleared away from the edge of the pond you will want to focus on keeping them from growing back. While you can not keep every cattail seed from blowing into your pond, you can extinguish their food sources to deter then from making a repeat performance. Apply some MuckAway™ pelletized bacteria around the shallow areas of your pond to help digest any nutrient-rich slime that has accumulated on the bottom of the pond over time. This layer of muck acts as fertilizer for new weed growth, smells bad, and as if you needed another reason, it feels terrible between your toes when you are swimming in the pond. Aquatic weeds can also use sunlight as a means to grow so you can benefit from using Pond Dye to shade the pond as well. Not only will you reduce the amount of sun exposure your pond receives you can also choose a color that accents your pond and improves the appearance of the water body.

Some people enjoy the look and coverage that emergent weeds like Cattails provide. If you have considered keeping a few around for aesthetic purposes rest assured it is absolutely harmless to do so. You can still control and maintain these areas of growth using Avocet and Kraken, just be sure to mark off boundaries to keep the weeds from slowly creeping their way back out into the pond and out of control.

Do You Know Who You Are Dealing With?

When faced with an outbreak of weeds in their pond some pond owners tend to rush into buying aquatic herbicides and algaecides in an attempt to clear up the pond as fast as possible. While we agree with the idea that your weeds need to disappear on the double, you want to make sure you take some time out to identify your intruder. When you know what you are dealing with your can then chose a product to treat it that will give you the best bang for your buck. If you are having trouble identifying a particular weed you can e-mail a couple close up pictures to The Pond Guy® at weedid@thepondguy.com or check out our Weed ID Guide.

What’s The Difference?

Knowing is half the battle in your war against aquatic weeds. So what do you need to know about Naiad to correctly identify it in a line-up of other unruly pond perpetrators? Naiad is an annual plant that branches profusely and forms very dense stands of rooted submerged vegetation. Leaves are dark green to greenish-purple, ribbon-like, opposite or in a whorl of three, mostly less than 1/2 inch long and 1/8 inch wide. Single seeds are found encased in the leaf sheath. Southern naiad reproduces by seeds and fragmentation. Flowers are at the base of the leaves but so small that they can only be observed with magnification. While Naiad is often confused with Chara at first glance, Chara has a strong, unpleasant odor and a crunchy texture that sets it apart from its counterpart. Chara also is very easy to pull out since it has no attached root base.

Pick Your Pony

You will find a stable full of products available for treating Naiad each with their own application methods and water use restrictions. Hydrolthol 191 for example is a granular that sinks to the bottom of the pond and is applied with a hand spreader. It carries water use restrictions such as a 3 day fish consumption restriction and a 25 day irrigation restriction. Ultra PondWeed Defense® on the other hand is a liquid aquatic herbicide that is applied via a Tank Sprayer and carries only a 5 day irrigation restriction. Read each herbicides application instructions, water use restrictions and dosage rates to determine which product is best for you. In addition to Hydrothol and Ultra Pondweed Defense®, Sonar™ A.S. can also be a viable option for treating Naiad.

Revenge Is A Dish Best Served Warm

For optimal results you will want to treat your pond when your water temps are above 50°F. Waiting for warmer weather in late Spring and early Summer ensures that the weeds in your pond are actively growing and will eagerly take the chemical you add to the water. Once the weeds are killed it is then safe for you to rake them out of the pond using a Pond & Beach Rake or something similar. Keeping your ponds nutrient load in check with MuckAway™ and PondClear™ and proper Aeration will make sure you spend less time wrestling weeds in your pond and more time enjoying your ponding season.

Beat Your Greens
As we approach our warmer spring and summer months, you may find yourself watching in awe as algae takes over your pond at an almost impossible rate. What is going on in your pond that is making it punish you so? Let’s take a look at the cause of algae and your approach on treating it.

Ready, Get Set, React
Unless you find your new algae bloom a welcome addition to your pond, you will want to get rid of it as soon as possible. Algaecides like Algae Defense® and Cutrine®-Plus Granular are great products to eliminate existing algae blooms. If you have trout, Koi or goldfish in your pond, you will want to use a non-copper based product like Clipper™ to do the job. While these products address the current outbreak in your pond, they will not treat the source of the issue or prevent future occurrences and they require repetitive treatments. Even after the algae bloom is killed, you will still have to do some legwork in terms of removing dead plant matter. Leaving dead algae in your pond will only hinder your quest for a clear pond by providing even more algae food in the form of decaying plant matter. For these reasons, using chemical applications to fight algae is referred to as a reactive approach.

Going Proactive
As the saying goes, “The way to algae’s heart is through its stomach”. While we might not be current with our sayings, this one still holds some truth. Eliminate the food sources available to algae and you will send it packing. Performing regular maintenance in your pond to prevent algae growth is a proactive treatment. Algae can utilize both available sunlight and nutrients held in your pond to stage its backyard assault. By adopting a proactive routine, you can keep your pond clean and clear all season long and save some money on repetitive chemical treatments.

The best step you can take in establishing a Proactive treatment plan is to implement aeration in your pond. Sub-surface aeration systems like our Airmax® Aeration Series will circulate your pond’s water column and infuse it with dissolved oxygen, which on its own will promote the colonization of beneficial bacteria. These beneficial bacteria will break down that same nutrient load your algae utilizes, thereby discouraging continued growth. The bacteria in products like Pond Logic® PondClear™ and MuckAway™ will reinforce the natural bacteria in your pond, ensuring that your pond is able to break down nutrients faster than they are being introduced into the pond. Without an available nutrient load, algae will have to utilize sunlight to generate food. By adding pond dye, you can not only beautify your pond, but also limit the amount of light able to penetrate the water surface. Pond dyes like Pond Logic® Nature’s Blue™, Twilight Blue™, or Black DyeMond™ give you the option to choose the color that best suits your pond while still obtaining a natural look. If you would like more information on choosing the right shade for your pond, click HERE.

We have packaged a collection of products to take the guesswork out of completing your pond maintenance and appropriately named it the Pond Logic® ClearPAC® . The ClearPAC® contains PondClear™ Beneficial Bacterial, Nature’s Blue™, EcoBoost™ Bacteria Enhancer and Algae Defense® . These products are designed to kill algae, clear water, reduce muck, and shade your pond combining the immediate results of reactive treatments with the economical preventative results of a balanced proactive approach.

Q. I have a ton of algae growing on my pond. What can I do to get rid of it? – Jeff in New York

The ice is finally off. You walk out to the pond for the first time, expecting to see your happy fish except….in their place is a happy, healthy sprout of algae! This may leave you thinking where do I begin? Here is a quick guide to get you started towards taking back your pond.

1) Give your pond short term relief. If you are in a climate where water temperatures are already above 50° Fahrenheit you can begin doing algae treatments. The chemical choice will depend on the type of fish contained in your pond, whether the algae is floating or submerged and how much area the algae is covering. For more detail on choosing the right chemical view our Weed Control Guide.

2)  Add Pond Shade. By adding pond shade you can reduce the amount of sunlight reaching into your pond.

3)  Rake the Pond. Once the algae is dead you can rake out the dead matter in order to reduce the amount of accumulation of muck in the bottom of the pond. Muck is a major food source for algae.

4)  Treat with Natural Bacteria. Adding natural bacteria such as PondClear™ & MuckAway™ will aid in quickly decomposing any organic material that does reach the pond’s bottom. You can also use EcoBoost™ to give your natural bacteria a little extra oomph.
Dyed Pond with Aeration5) Aerate the Pond. If you aren’t already aerating, aeration is a great way to increase the oxygen contact for the bacteria to be more efficient and also to help keep your fish healthy for the upcoming warmer months.

If your pond hasn’t quite hit the 50° F temperature you can still be proactive about algae reduction and prevention. Dye and aeration is not dependent on temperature and can be started at any time.
