Do I need to cut down the cattails before I spray them? | Ponds & Lakes Q&A

A: Slashing through cattails would certainly be cathartic, wouldn’t it? Well, we don’t recommend it – at least not yet. The best way to rid your pond or lake of those nuisance plants is to use a systemic herbicide with a surfactant, like Shoreline Defense® and Treatment Booster™ Plus. Apply the mixture on the plant’s leaves with a sprayer. The herbicide then kills the entire plant, rhizome and all.

Destroying that rhizome is critical to controlling cattails. Along with cottony seeds that explode from their brown, conical flowers, cattails propagate via their rhizomes, or root systems, which produce shoots in the fall that sprout in the spring. When you stop their underground spread, you can manage their footprint in your pond or lake.

If you’re new at removing cattails from your pond, here are some tips to make it hassle free.

  1. Treat the cattails between late July and first frost, when the plant is actively growing.
  2. Use a tank sprayer, like the Specialty Pond Sprayer, to apply the herbicide to the leaves that are growing above the pond or lake’s surface. Make sure they’re at least 12 to 18 inches out of the water.
  3. Completely wet the foliage for maximum results when rain is not in the forecast for 24 hours.
  4. Once the plants have completely died and turned brown, you can get out your Weed Cutter and slash through those dead stalks. Aim for the base of the plants, which will allow for easier removal with your Pond & Beach Rake.

Cattails aren’t all bad. Besides adding to the aesthetic value of your landscape, they also make a good home for a variety of birds, insects, amphibians and underwater inhabitants. Consider leaving a few of the cattails around for those critters – but keep the plant carefully controlled with Shoreline Defense®.

Pond Talk: Various parts of the cattail are edible, including its rhizome, young shoots and green flower spike. Would you ever consider harvesting and eating your cattails?

I have a lot of cattail growth. Should I spray it now or just wait until spring? | Ponds & Lakes Q&A

A: As long as those cattails are green and growing, you should spray them. Fall is actually an ideal time to treat pesky pond weeds because that’s when the matured plants soak up nutrients through their leaves to prepare for the coming winter. They’ll do the same thing with the herbicide—but it will cause their demise!

If you don’t spray the cattails, they won’t dry up and die. No, that would be too easy! When the weather gets cold, the leaves and stems will turn brown and dry up while the tuberous root systems in the soil below the surface lie dormant. Those tubers, having stored up energy all winter, will explode with new shoots and growth in the spring.

Plus, all that dead and dried up foliage will fall into your pond, adding decaying organics to the mix. That detritus—which is like fertilizer to pond weeds and algae—will cause an even bigger headache next year.

Spraying cattails now when they’re still green is your best bet. Here’s how we recommend you do it.

  1. Spray Growth: Using your tank sprayer, treat the cattails with Shoreline Defense® with Treatment Booster™ PLUS. Apply the herbicide, which has no usage restrictions, directly to all above-water foliage. The plant will draw it in through its leaves and die—roots and all.
  2. Spray Again: Wait about two weeks for the herbicide to kick in, and then repeat the process again to be sure you get that weed under control. This will be necessary in ponds with thick, abundant cattail growth.
  3. Remove Dead Foliage: As the cattails die, cut and rake out dead debris with your weed removal tools, like a weed cutter and pond rake. This will cut down on decomposing organics left in the pond, making it easier to get on top of any new growth in the spring.

Take some time during this late summer and fall to treat cattails. You’ll be glad you did!

Broad Spectrum Emergent Weed Killer - Shoreline Defense® & Treatment Booster™ PLUS

Controlling Cattails – Reclaim Your Shoreline | Learning Center

Cattails and other emergent aquatic plants can add natural beauty to any pond or shoreline, but if left unchecked for too long, they can overtake these areas and create a maintenance nightmare. A consistent program is the most efficient way to combat excessive spread of unwanted weeds. Fortunately, there is a simple solution to keeping cattails in check. Follow these tips to maintain a pristine shoreline all season long.

Set Boundaries – Cattails are not all bad. They are nature’s solution to providing habitat for wildlife, preventing soil erosion and they make a great visual barrier to add some privacy to your pond. Like most things however, cattails are best in moderation. Highlight boundaries where you would like to contain cattails by using landmarks, rocks or other unobtrusive markers. Treat cattails that try to stray from these boundaries to keep their growth under control.

Spray Unwanted Growth – To maximize the effectiveness of your cattail treatments, wait until there is at least 12” – 18” of exposed growth to apply product. A systemic herbicide like Shoreline Defense® & Treatment Booster™ PLUS will kill the cattails down to the root to prevent the plant from re-growing. The roots of cattails are the most difficult part of the plant to kill. So, allow the mixture to absorb into the plant for one to two weeks. This will ensure the treatment gets into the root system. Do not try and stretch the application further than the instructions state. This will likely lead to unsatisfactory results and end up in more product used in the long run.

Remove Dead Cattails – Wait until treated cattails are brown and wilted to remove them from your pond. Cutting them down too early will prevent your chemical treatment from fully reaching and killing the cattail rhizome (root) resulting in a quick return of the weed. Don’t leave dead cattails, or any other vegetation, in your pond to decompose. This decomposition turns into nutrient-rich pond muck that fuels new weed growth. Tools like the Weed Cutter and Pond & Beach Rake exist to make the process as quick and simple as possible.

Retreat As Needed – Due to the fact that cattails have a robust root base, multiple treatments may be necessary to properly gain control. Once under control, they will make a nice addition to your landscape and encourage wildlife to call your pond home.

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.
