Dishsoap as an effective moss killer

By August 24, 2010

Follow me on:

Moss is not always considered a weed, but don't tell that to those who have tried to deal with it. Here's a 'green' recipe for getting rid of moss in a lawn. It's safer than chemical pesticides and only a fraction of the cost. It sounds odd but it works and is used by turf professionals everywhere.

  • 4 ounces Ultra Dawn liquid dish soap
  • 1 gallon water

Gently mix contents in a 1-2 gallon hand sprayer. Holding the spray nozzle a couple of inches from the target, drench moss with solution. Moss will turn orange/brown in 24 hrs and eventually dry up while the surrounding grass takes over.

Here's another interesting home-made solution.

Vinegar as an herbicide.

Some organic lawn care tips for good measure.

Will this dawn/ water mix for controlling/killing moss hurt my garden plants?

I’ve only used it on turf and it did not harm it. If you are unsure about a plant, maybe test the mixture in an inconspicuous are and check for damage.

I need a home made moss killer for my deck. The material of my deck is not wood, it is Evergrain. I am also needing it for my cement driveway. ?????? HELP ??????

Did you really mean to say pesticide, when you are referring to an herbacide? Dawn (or any) dish soap and water in a spray bottle will kill most insects and IS a good, organic herbicide. never heard of it killing moss, which is a plant, after all.
