Some of the most common complaints we get are about cattails….


“Cattails have overtaken my pond. Now it looks like a swamp”

“I can’t see my pond through all the cattails”


Cattails (typha sp.) can, and will, grow in water up to SIX FEET DEEP. It’s true – I’ve witnessed it. Conventional wisdom has them stopping at four feet of depth, but a few years ago I went wading in a pond to cut some cattails a couple weeks before a wedding was taking place in the adjacent gazebo. Lo and behold those buggers were growing all the way out to six feet of water, and they were just as tall as the rest at approximately 7′ above the waterline. That’s right, do the math – these cattails were 13′ TALL!

So long story short – if you have a considerable area of your pond that is less than 6′ deep, DO NOT allow cattails to grown unless you plan to keep them under control.

“How do I keep them under control?”

Glad you asked. There’s a few ways:

Use approved aquatic herbicides seasonally. The best ones contain Glyphosate, which is systemic and kills the roots. Spray in early fall before the stalks start to turn brown. Always use a surfactant, as well as Breakdown Booster.

Cut them at the waterline. This is labor intensive, and you will get wet! Cutting the cattails frequently at the waterline will slow their growth and spread. This prevents seed pod formation and causes the plant to starve itself by continuously trying to send up new growth. Over time (as in several years) you can dramatically decrease their spread.

Dig and pull them out by the root. Hah! Yeah, trust me. Don’t even try it. Unless you like back injuries. If you have an excavator, give it a shot. But be careful not to cause a leak in your pond by digging through the clay bed.

I prefer the first two methods, and which one depends on the individual situation.

Check out the following videos describing method number two – Cutting them down and treating the pond with Breakdown Booster.
