Emulsifying Neem Oil with Neem Soap

 In Tips and Tricks

“Big box” brands of neem oil are undeniably easier to use but “real” neem oil is worth the extra trouble. That’s because major brands of neem oil have removed the most important insect-repelling ingredients to sell as a separate, more expensive treatment — then they add in inert ingredients they don’t even identify. Those inerts make it easier to mix with water, but you no longer know what you’re spraying on your food.

NimBioSys is a cold-pressed, full-spectrum neem oil so you’re using it exactly as Mother Nature intended. But like any oil and water mixture, neem needs to be emulsified before it’s used on your plants. If not, you’ll end up with too much neem burning some leaves and not enough neem to control pests on others.

We’ve been using neem soap as an emulsifier for the last few years and have been delighted with the results. It’s easy and cheap to make!

Just put a bar of our all-natural neem aloe soap in a gallon of hot water and leave it overnight to
dissolve. (We upcycle milk cartons, so we slice the soap to fit it through the spout, which makes it dissolve faster.)

Shake the diluted soap mixture well and mix one cup in a gallon of water. We believe the soap makes the oil more effective so you can dilute it below recommended levels. Rather than a tablespoon of neem oil per gallon, start with a teaspoon and track results. You may increase neem oil to an ounce per gallon but that hasn’t been necessary here.

If you prefer to follow the EPA recommendations, add 1.3 tablespoons of neem oil to a gallon of water with ¼ cup of neem soap to emulsify it.
