Q: My pond is full of floating algae. How do I get rid of it?

C.J.- Dumas, AR

A: With summer temperatures settling in, algae blooms are coming out swinging. Bright sunshine and warm temperatures trigger green growth, so it’s critical to keep floating and submerged algae in check before it grows out of control.

For the health of your pond and its inhabitants, keeping algae blooms to a minimum is necessary. Here’s an approach that works to eliminate the green stuff and prevent it from taking over:

Treat the Growth
First, use an algaecide to great rid of the algae bloom. You can treat floating algae with a fast-acting liquid spray like Algae Defense® Algaecide with Treatment Booster™ PLUS, which treats floating algae and chara that’s less than 3’ deep. Simply spray it on with a pressurized sprayer to combat floating and bottom-growing algae.

Submerged algae can be treated with sinking granular products, such as Cutrine®-Plus. It works well for algae submerged deep in your pond or lake, such as Chara. It’s best distributed on a calm day via a granular spreader in the morning before mats form.

Remove the Dead Algae
Once the algae is dead, you should remove it. Why? By leaving the dead foliage in the lake, it will start to break down and become nutrients—or algae food—for new blooms. It’s a vicious cycle!

Use a pond skimmer, like the PondSkim™, or a rake, like the Pond & Beach Rake, to prevent that muck from accumulating.

Add Beneficial Bacteria
Three days after you’ve used algaecides, treat your pond with PondClear™. It contains beneficial bacteria that gobbles through the organic material that’s suspended in the water column. The result is a lake filled with clean, clear, odor-free water—and a healthy ecosystem for your game fish and other pond inhabitants.

Shade Water with Pond Dye
Finally, be sure to add blue or black pond dye to your pond throughout the spring and summer. By reducing the amount of sunlight that shines through the water and stimulates plant growth, you will ultimately reduce the amount of algae.

How Do I Get Rid Of Phragmites? | Ponds & Lakes Q&A

How Do I Get Rid Of Phragmites?

Robert – Steamboat Springs, CO

Phragmites, also known as common reeds, are wetland grasses that can grow up to 15 feet in height. They quickly become a nuisance because they form dense patches that choke out native plant and wildlife species, block shoreline views, and reduce access for swimming and fishing.

Completely eliminating phragmites takes several treatments. The majority of the plant is an extensive underground root system that is very difficult to fully eliminate. You can control the density and spread of phragmites with regular chemical treatments applied with a pond sprayer. Consider using an herbicide such as Shoreline Defense®, which carries no restrictions on recreational use or livestock consumption of water from the treatment area.

Once phragmites have died, you should cut or burn the dead vegetation. The best time to treat phragmites is the summer when the plant is actively growing and seeding.

Should I cut cattails before I treat them? | Ponds & Lakes Q&A

Should I cut cattails before I treat them?

Kevin – Boise, ID

At first blush, it seems pretty logical to cut cattails before treating them. But when you understand how the treatment works, it’s immediately clear: cutting first is the wrong way to go.

Here at The Pond Guy®, we’re big fans of Shoreline Defense® Aquatic Herbicide. When it comes to eradicating cattails and other grassy plants, nothing does a better job. Shoreline Defense® works best when use with a powerful surfactant that breaks down the waxy cuticle of the plant, allowing the herbicide to penetrate the stalks of cattails. The cattails then do the rest of the work, carrying the chemical treatment throughout the root system to kill the plant at its source.

Because cattails only use a small portion of their root system at one time, a single application of Shoreline Defense® should be allowed to work for a week or two before cutting the plants down with our Jenlis Weed Razer™ or Jenlis Weed Razer™ Pro Aquatic Weed Cutter. Occasionally, some roots will survive and send up new growth. When that happens, simply reapply Shoreline Defense®, wait an additional week or two, and repeat the process.

So, while it might be tempting to take out your frustrations and cut down offending cattails to remove the blight before treatment, take your time. The results will be worth the wait.

I have phragmites in my pond, and they are so aggressive they even outgrow the cattails. What should I do? | Pond & Lakes Q&A

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 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.

Controlling Cattails – Ponds & Lakes

Dyed Pond

 

Controlling Cattails
Cattails provide a natural habitat for fish and help reduce nutrients and sediment that run off into your pond. They are also used in some ponds to add to its overall aesthetic appeal. While there are a few benefits to having cattails around your pond, at what point do they become an inconvenience and how do you get rid of them?

Mark Your Territory
While you enjoy the presence of cattails in your pond, they can quickly take over your pond and become an unsightly pest. An easy way to keep your cattails in check is by marking boundaries in your pond. By establishing reference points, it will be easier to tell when your cattails are trying to spread out, enabling you to address the situation before it has a chance to get out of hand.

Spray it, Don’t Say It
When a pond becomes overgrown with cattails, it can seem like regaining control will become an epic battle. Using a spray on aquatic herbicide like Shoreline Defense®” will make short work of your cattail woes. Treating cattails is as simple as mixing Shoreline Defense® into a tank sprayer with the corresponding amount of water and spraying it onto the plant surface. The herbicide will soak into the plant and work its way to its roots, killing it completely. Once the cattails are dead, you can cut them away from your pond with an aquatic weed cutter and rake them away from your pond.

Even Super Heroes Use Sidekicks
Using a surfactant like Treatment Booster™ PLUS will greatly increase the effectiveness of Shoreline Defense®. Treatment Booster™ PLUS helps break down the waxy cuticle of the cattail leaves, enabling a more effective uptake of herbicide. Mix 2 ounces of Treatment Booster™ PLUS for every gallon of water and Shoreline Defense® solution and you are ready to spray! Treatment Booster™ PLUS can be used in a number of aquatic herbicides and is not exclusively used with Shoreline Defense®.

New and Improved
To make your pond maintenance even easier, you can now purchase Shoreline Defense® & Treatment Booster™ PLUS Combo.
