Do I need to cut 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?

Do Cattails actually die in the winter or can I do something to prevent them from coming back? | Pond & Lake Q&A

Do Cattails actually die in the winter or can I do something to prevent them from coming back?

Brian – Holland, MI

As grandfather used to say, “never trust a sleeping cattail.” Actually, grandfather never said that. But he should have – because it’s true.

During the winter months, cattail foliage dies off. Leaves and stems turn brown and dry up when the weather gets cold, and optimistic pond keepers dare to imagine their backyard water features without the scourge of unwanted cattails. But deep beneath the pond, cattail roots are alive and well in their dormant state, saving up their energy to come back strong in the spring.

Fortunately, cattails aren’t invincible. Depending on the season, enterprising pond owners can take steps to eliminate cattails, leaving their backyard water features in great shape to host more desirable aquatic plants and fish.

When winter rolls around, and cattails have dried up, it’s worthwhile to cut the dead foliage and remove it. Our Pond Rake and Weed Cutter is specifically designed to make this process quick and easy. While this won’t kill the cattails, it will lay the groundwork for a successful spring offensive.

In spring, summer and fall, when cattail foliage is thriving, it’s time to apply our Shoreline Defense® Aquatic Herbicide. This safe, powerful herbicide is applied directly to all above-water cattail foliage. Once applied, the herbicide attacks and kills the entire plant – including its root system. Once the plant is dead, you’ll want to resume the use of your Pond Rake and Weed Cutter to remove the dead plants and prevent their potential to spread.

While Shoreline Defense® is effective on spring growth, it’s most effective during late summer and fall, when foliage is at its peak.

Controlling Cattails & Phragmites – Pond & Lake Q & A

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.
