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!

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?

Picture of Cattails & Phragmites

Q: How do you control emergent cattails & phragmites around my pond? -Several Customers from across the US

A: At first site, cattails and phragmites seem to add a natural look to your farm pond. But before you know it, they grow out of control and wrap around the pond causing a very unappealing look. Here are 3 Easy Steps to killing cattails, phragmites or other emergents: Spray … Cut … Remove.

1.) Spray – The best products to use to get rid of emergent weeds is the Shoreline Defense® & Treatment Booster™ PLUS Combo. It it always best to read the product labels for dosage rates, but a great suggestion is to mix 8 oz Shoreline Defense®, with 4 oz Treatment Booster™ PLUS, with 2 gallons of water into a pond sprayer. This recommendation will treat approximately 2,500 sq. ft. of emergent weeds. It is best to spray when cattails or phragmites are around 12″ high or taller. Before cutting and removing, it is recommended to wait a week and a half to allow the chemical to get into the root system. By not allowing this time to pass or cutting too early will allow the root system to stay alive.

2.) Cut – Use a Weed Cutter to cut at the base of the cattails/phragmites. This will allow for easier removal.

3.) Remove – Use a Pond & Beach Rake to assist in removing the of the cut cattails/phragmites.
