The Benefits of Dr. Bronner…

We have used Dr. Bronner’s Castile soap as an insecticide for many years. We find it works wonders in the garden and, if you choose the peppermint or lavender, it takes the experience to a whole ‘nother level. :)

Got Castile Soap? -
Jack Falker

After publishing my last post on spraying non-toxic stuff, instead of the usual fungicides and pesticides, I was reminded by my good friends, Diane and Dick Lawson that they are spraying almost exclusively Castile soap on their garden (which is one of the nicest in the Twin Cities).

I asked Diane, a recently retired high school physics teacher, to explain exactly what Castile soap is vs. the liquid dishwashing soap I’ve been using and was recommending in my article. I was surprised when Diane told me that Castile soap is made primarily from olive and other vegetable oils, which presumably leave a beneficial coating on the plants, vs. detergent soap. In other words, Castile soap is a natural surfactant that remains on the surface of the leaves, much as a surfactant fungicide might, as well as acting as a deterrent to insects.

I remember using Diane and Dick’s Castile formula on my garden a few years ago and that was the summer I saw virtually no thrips or aphids. Diane would contend that’s the case in her garden every year.

Until now, my problem with using Castile soap has been the laborious preparation. They use “Kirk’s” Castile soap in bars, which has to be dissolved in water and then mixed into your sprayer. Their procedure is to dissolve half a bar of Kirk’s in a gallon of water and then mix one cup of that soap mixture into each gallon of spray mixture. For example, for five gallons of soap spray, you would use five cups of the Kirk’s/water mixture.

After talking to Diane the other night and remembering that I didn’t enjoy dissolving bars of soap in water, I “Googled” Castile soap to better understand it and here is what I found… (link) (which includes a picture of a bar of Kirk’s).

I also found this story about making your own Castile insecticidal soap. (link)

If you Google: “Castile soap insecticide” you will find several other articles, as well.

I also found that Target sells Dr. Bronner’s Castile soap in liquid form, so that means you don’t have to dissolve bars of soap in water to use it. Here is the Target shopping site for Castile soap. (link)

I enlarged the label of Dr. Bronner’s Castile Soap and here are the ingredients: Organic coconut and olive oils, organic hemp oil, organic jojoba oil, lavandin extract, organic lavender oil, citric acid, and vitamin E. Now that sounds like something I wouldn’t mind spraying on my roses and, if I happen to get some on me, I’ll just lather up and wash it off!

I believe that adding baking soda to the Castile soap mixture at a rate of 3 TBP per gallon would probably make it a better fungicide, as well.

You could also substitute 2 TBP of Castile soap for the dishwashing detergent in the cider vinegar/aspirin, soap mixture I recommended in my last post (link).

Thanks Jack for such thorough information!

  1. Interesting post. In Europe is is illegal to use anything that has not been approved as a pesticide for that purpose. Not a lot of people know this, but according to the Royal Horticultural Society ‘All chemicals being used to control or deter animals are classed as pesticides in the UK and EU, and must be registered and approved for this purpose by our own government and the EU…Anything that has not been through the system is illegal to use as a pesticide, however safe that chemical is perceived to be. Heavy fines can be imposed for breaches of the laws relating to pesticide use’.
    Having said that, it doesn’t stop us!!

    Beautiful misty morning photo!

  4. Beautiful farm photo and post Teresa. Keeping our gardening practices soil friendly “uppens” the earth and protects the ecosystem that produces our lovely blooms! It’s the least we can do.

  5. What a fascinating article about the Castile soap! I will put this in my garden file, and pass on to others. Gorgeous inspirational picture to start my day….
