Why are cat tails so hard to get rid of in your pond?



  1. 0 Votes

    Cattails thrive in a number of environments, particularly near bodies of water. They have a high growth rate and may overrun a pond to a point of excess. Here are some techniques for cattail growth control / removal: cutting cattails about an inch below the water will deprive them of the oxygen, consequentially killing them; lowering the water level will deprive them of exactly that, resulting in successful removal (if the cattails spring seeds, the process will need to be repeated the following year); deploying pesticides will accomplish the same, although they may also kill other living organisms in the pond.

    Because cattails are thick, they reduce the flow of waves and capture sediment and silt. They harbor many microorganisms in their roots and studies show they can be beneficial in removing pollutants from water. But, thats not to say that you shouldn’t try to ensure a balance of the plants if they are taking over. They are hard to remove because they have solid, strong support and root systems. But you can try mowing, pulling, flooding, or dredging the stubborn things.

    This should be easy.  Cattails will only grow in water up to a certain depth, say 3 feet.  So if your pond goes deeper than that, cattails won’t ever take over your whole pond.  They also spread primarily by underground rhizomes.  So you could build an underwater barrier or dig a trench to contain their spread, if necessary.  I wouldn’t ever recommend using pesticides.  And ripping them up or killing them is not only wasteful, but it may not do any good as they continue to spread.  If you have a vigorous population of cattails along the edge of your pond, consider yourself fortunate and enjoy them!
