Errors in the video because I was too lazy to reshoot and I'm dumb:
-neem oil isn't a liquid because of water in it... its because the oil is above its melting point
-sometimes depending on the surfactant/emulsifier you may need to heat the water during the initial mixing steps when you start adding water
-I have had people mention a lack of success with dr. bronners castile soap, I never had those issues but I have primarily used polysorbate-20 and more recently quillaja, I will no longer recommend castile soap
The internet is filled with regurgitated "garden tips" lifted from gardening publications in the 90s and 2000s internet sites and neem oil how-to's are particularly rife with misinformation. Contrary to popular belief throwing dish soap, neem oil and water in a spray bottle and shaking is a terrible method to disperse your neem oil so that you can properly apply it to your plants. Neem oil should not stunt, or burn your leaves if applied properly. Many people kill their pests but also set their plants back by using crude neem oil sprays. Properly emulsifying your neem oil greatly enhances the effects of the neem oil on insects and absorption into plant tissue and reduces the potential harm to your plants. If you follow the three key aspects I've outlined you can have a reliable reproducible, insecticidal tool in your pest control arsenal:
1. appropriate non-ionic emulsifier/surfactant like cosmetic/food grade polysorbate 20 or quillaja saponins

2. high quality, cold pressed and minimally processed neem oil.

3. soft, low tds, low carbonate hardness water or pure water.
General Ratios for 1000mL/1quart
1mL or 1/4 tsp of quillaja saponin or 5mL of tween 20 or
~4mL or 1tsp neem oil
1000mL deionized/rainwater or low tds/low hardness water
Follow label dilution and application schedule. In general: Apply neem oil emulsion when leaf temps are below 75F, preferably in the evening after pollinators and other beneficials are less active.
