How to Get Rid of Cattails?

Cattails are tall grass-like plants that grow in wetlands and around water bodies like ponds, lakes, and streams. These plants are beneficial to the ecosystem as they provide food and habitats for many wildlife species. However, this can become invasive and overgrown in some areas, causing problems with drainage and water flow. In this article, we will discuss various methods of getting rid of cattails.


Hand-pulling is the easiest and most economical way of removing cattails. This method involves pulling the plants out of the soil by hand or using a weeding tool. Hand-pulling is effective for small areas but may not be practical for larger patches of cattails.

The best time to hand-pull cattails is in the fall or winter when the soil is moist and the plants are dormant. Alternatively, you can also pull this during the growing season, but it may require more effort. Be sure to wear gloves and protective clothing to avoid irritation from the prickly leaves.

Mowing and Cutting

Mowing and cutting are other effective methods of controlling this plant. These methods work well for large areas and can prevent the plants from going to seed and spreading. Mowing or cutting cattails 2-3 times a year can gradually weaken the plants and reduce their growth.

When mowing or cutting cattails, it is important to cut them as low to the ground as possible. This will prevent the plants from regrowing and spreading. The best time to mow or cut cattails is in late spring or early summer, just before the plants start to flower.


Dredging is a more invasive method of removing cattails. This method involves removing the soil and plant material from the water body to eliminate the cattails’ root system. Dredging can be effective for large areas, but it is expensive and can cause damage to the ecosystem.

Dredging should only be performed by professionals who have experience and the necessary equipment to perform the task. The best time to dredge cattails is during the fall or winter when the water levels are low and the plants are dormant.



Flooding and freezing are natural methods of controlling this plant. These methods work by exposing the plants to extreme conditions that can kill or weaken them. Flooding involves raising the water level in a wetland or pond to cover the cattails, depriving them of oxygen and sunlight.

Alternatively, freezing involves exposing the cattails to freezing temperatures for an extended period. This method works well for small areas and can be achieved by covering the plants with a tarp or plastic bag and exposing them to extreme cold.

Caution should be taken while using flooding and freezing methods as they can result in the death of other beneficial plants and animals in the ecosystem. These methods are also dependent on the unpredictable weather conditions.


Chemicals can also be used to control cattails. Herbicides are the most effective chemical treatment for cattails. Herbicides work by killing the plant’s root system, preventing them from regrowing. It is essential to use the right herbicide and follow the manufacturer’s instructions to avoid harming other plants and wildlife.

Chemical treatment should be performed by professionals who have experience and knowledge of the chemicals to prevent harm to the environment. It is also essential to follow the manufacturer’s instructions and local laws regarding herbicide use.

Preventing This Plant Overgrowth

The best way to control cattail overgrowth is to prevent it from happening in the first place. Here are some tips to prevent cattail overgrowth:

1. Maintain proper water flow. Ensure that drainage systems are functioning correctly and that water bodies have a proper flow to prevent cattail overgrowth.

2. Control nutrient levels. Cattails thrive in areas with high nutrient levels. Regularly monitoring nutrient levels and reducing them can prevent cattail overgrowth.

3. Regular maintenance. Regular maintenance like mowing, cutting, and hand-pulling can prevent cattail overgrowth and keep them under control.

Cattails can be an essential component of wetland ecosystems, but overgrowth can cause problems with drainage and water flow. There are various methods of controlling cattails, including hand-pulling, mowing, and cutting, dredging, flooding/freezing, and chemicals. It is essential to choose the right method for your situation and follow the manufacturer’s instructions to prevent damage to the ecosystem. The best way to control cattail overgrowth is to prevent it from happening in the first place by maintaining proper water flow, controlling nutrient levels, and regular maintenance.
