  • This dudes knowledge is amazing ! He’s my go to for plant / garden information! The fact he is providing this information for free is an honor! He is a scientist, enough said 🥰 Thank you for allowing us inside your brain and providing us such amazing knowledge!
  • @Me-gf5ym
    Good information, and another idea. If you happen to use Dr. Bronner's Castile Soap already, you don't need to go out and buy the Safers concentrate. Dr. Bronners soap contains relatively benign organic ingredients and potassium hydroxide, not sodium hydroxide.
  • Good info! I knew the difference between detergent and soap AND was trying to save money. Knowing that sodium hydroxide disappears during the saponification process of soap making, I saved my soap slivers in a jar of water over for about a year. Then I used the resulting soap slurry to make my insecticidal spray. It was so-so, left some residue on my leafy veggies, but didn't kill my plants. Then I found bulk liquid castile soap at my local co-op. Seeing it is made with potassium hydroxide, it worked fabulously! No sickly plants, no residue, no aphid or spider mites!
  • @racebiketuner
    Great stuff! I'm really looking forward to your how-to-make-it vid.
  • @gforcekaras
    Great straight talk about these bogus internet recipes! Thank you! Looking forward to the next video about the recipe!
  • Thank you for taking the time out to make this video it's very helpful and informative, I've definitely learned something today.thank you.
  • @justetv0505
    I just bought that garden safe insecticidal soap from tractor supply about an hour ago to use this evening on my little garden. A few plants have bugs eating their hearts out! Then I watched this video. This guy is on point. So I subscribed to learn more. I have ten thousand videos saved to watch over and over to weed out what's true and not worth using. Doc here said that this is less harmful so I'll use it sparingly and only on the plants that need it. Last year I made up a concoction from a video to keep the bugs down and it killed everything!!!!! So I'm kinda leary about these videos. There's a few who mean you well and this guy is one!!!
  • @shawnsg
    I don't know if your going to mention this in the next video but you can find soaps made with potassium hydroxide instead of sodium hydroxide. Usually they are labeled as Castile soap.
  • @jcribbdvm
    Thank you Sir for sharing this information. I wish I would have found this video decades ago. I have suspected a few times in the past that I actually injured the plant more than the insects in my efforts to use the homemade “dawn” water +/- alcohol mixture.
  • I have learnt this by experience. Used dawn last year to get rid of aphids and killed all my bean plants instead. Thanks for the detailed information
  • @tinab7791
    I knew I did that to my peppers myself. Dang it. Thank you for explaining. They seem to be recovering okay but I will definitely change my practices in the future.
  • @Me-gf5ym
    I use Dr. Bronners liquid castile soap with Tea tree oil, available at London Drugs and most health food stores. Worked like a dream on the aphids that attacked my lupin plants this spring.
  • @tsumplay3094
    thank you so much. I had tried the detergent method, the aphids did die, but my plant not healthy as before.
  • @survivalist0723
    Right so, and well explained. I presume the sodium soaps and the detergents also damage the soil in some ways... Maybe you can explain this in another video to us.
