Cattails can spread rapidly to water depths of four feet.
Established cattails over time trap sediments, grass
clippings and leaves. As this foundation builds creating shallower
conditions the cattails further encroach accelerating the transition
from open water to a dominant emergent weed pond or shoreline.
Pond and lake views are reduced by cattails that
can grow to ten feet.
Q. What are the best control
A. Herbicide Application:
The best method is the application of a herbicide
with the active ingredient called glyphosate
found in brands like Rodeo and Shore-Klear. Rodeo herbicide
is applied directly onto the dry emergent portion of the plant. The
herbicide will translocate down into the root system controlling the
We recommend cutting only when there are a few Cattails
in the way. Cutting is labor intense and regrowth typically occurs
within the same season.
Q. When is the best time to treat?
A. Cattails should be treated when mature from July to approximately
one week before the first killing frost. Cattails can be treated sooner
but the need for a repeat application increases.
Q. Can I treat a portion of the Cattails?
A. Yes, because the application is topical it will only affect the
cattails that are sprayed so you can choose to control a percentage.
Q. How do I actually apply the product(s)?
A. Liquid herbicides like Rodeo
should be applied by a hand held pump up type sprayer
or a Solo
Back pack sprayer.
Q. Do I have to treat Cattails every year?
A. No, control can last anywhere from three to five years or more
depending upon if you treat all the cats or a portion. Ninety plus
percent of Cattails are controlled the first year within the chosen
treatment site. Some follow up is usually required the second season.
Q. Is the water safe for humans, fish and wildlife after treatment(s)?
A. Yes, There are no swimming, fishing or irrigation restrictions
with Rodeo herbicide. There are no restrictions for domestic pets or
wildlife such as ducks, geese, cats, wild birds or the family dog.
Q. How long before I see results?
A. Generally within ten days the tips will begin to turn brown migrating
