Just some clarification :) Bar soaps are typically made using sodium hydroxide; liquid soaps are typically made using potassium hydroxide. "Castile" soap can be either: historically (and typically) it must be made from olive oil to qualify as castile soap regardless of whether it's solid or liquid. Agree that it's probably best not to use either on plants, or as little as possible.

I watched a previous video of yours on this subject. Thank you for the clarification of detergent vs soap.

SO many people are obsessed with dish soap for plants when Castile soap or tween 20 will do so much better.

Thank you for all the information you share with us.

Thank you so very much for this very helpful information. God bless.

Thanks for your content . I use Dawn , salt and vinegar on weeds only

I used that last year to kill the Spotted Lanternfly pandemic we had. Killed the bug as I was told, and as you pointed out here, it killed the plant as well. (Grapevine)

Thanks! I was looking for a cheap surfactant for herbicide. The more harm the better for these weeds.

I always called it dishwashing detergent. Tried it once on a warm day and the plant cried. Never used it again.

You're like "The most interesting man" of gardening ❤

Awesome video. Many thx. 🎉

Great contents. Thanks for sharing. This video brings back old memory 30 years ago in biology and chemistry class! I cannot agree more about your comments on product labelling. Don't we all love about marketing 🤣 Happy gardening everyone!

Very informative. Can you talk about Horticultural Oil and how to use it during the growing season ? Can we use Vegetable Oil as an alternative to Horticultural Oil ? Thanks.

thank for the info. I wonder how about wetting agent ?

Similar with the sodium polyacrylate(bad) vs potassium polyacrylate(better) for those old school gelled/jello like planters you would see all over. I use KOH (vsNaOH) and HCI for plants so i see where castile can make a difference. I hadn't a clue they used different saponification's.

Thanks for the information

Thank you so much!

Use cheap baby shampoo…..NOT to kill anything but to make water “wetter”….small amount mixed with water….will increase the amount of water getting to the roots by breaking the surface tension of the soil…..

I just started Dawn in order to stop whiteflies. Yes it killed the white flies but it is also put my watermelon and cucumbers in a terrible state. I do have surfactants can I use for my lawn when I spot treat weeds. I think I may give that a try instead. Thank you for your information

I LIKE TO USE GASOLINE

I use hand liquid soap, works a treat !

For 70 Year’s my grandma through her dish water on her plants outside and her plants were beautiful. Maybe it’s made differently these days.

Thank you so much

I used Dr Bronners castille soap with neem oil and haven't had any issues. Just not on a consistent basis.

Great content.

Thank you Mr.P 🌷💚🙃

Going with a Castile soap, I would opt for Dr. Bronner's Unscented Baby formula. No added fragrance. No added essential oils. No added salts. The only questionable part would be the citric acid and Tocopherol (Vitamin E).

Actually soap makers aren’t using sodium hydroxide because it’s cheaper than potassium hydroxide. The choice between the two comes down to the type of soap you are making. Sodium Hydroxide creates a solid soap. Potassium Hydroxide will not harden to a solid state so it is used to make liquid soaps.

Lucky i watched this i was going to use it

I’m gonna say this to be helpful not to simply complain, but it seemed like this was way longer than it needed to be. It was slow and repetitive. That may just be his speaking style and some people may enjoy it, but myself and I think most people these days want to get right to the point. We could’ve learned about surface tension and detergents versus soap, and what things to use instead of dish detergent in just a minute or two.

I use dawn on all my plants works great

Thanks for the video. I had some aphids that were eating up a newly planted Apple tree. My neighbor who knows everything about everything told me to mix some Dawn in water and spray them. The Aphids were gone but the leaves turned brown overnight.

👍👍👍Thank you

Where is the 10c soap video? KZfaq not showing the link

Does this apply to grey water from the washing machine aswell?

Thankee

Thank you!!!

I have been using dawn in the garden to make a drench for fire ant mounds. Not on plants but I'm sure it probably gets on a few roots. Do you think I should stop?

What affect will detergent have on the soil?

I always wondered about using soap. Im so glad I never got into that habit.

What about Yucca extract as a surfacant?

Very informative- but I can’t find insecticidal soap concentrate in Hawaii the stores make more money selling the premixed stuff for $11 a for 16 oz. Amazon won’t ship the concentrate here either 😢

Why are people that’s using dawn dish liquid saying it killed the bugs and not their plants.. if it kills plants why are so many happy with it😊

I only use Palmolive so I’m ok 😊

I used Safer soap insecticide on my plants last night. This morning my petunia blossoms were bleached. No bugs tho......😒

Tocopherol is Vitamin E.

what about using a very small amount of glycerin

i am so sad... I use dish soap as part of a neem oil recipe... I did not know I was hurting plants

Just use a weak solution then hose it off the plant after a minute or two. Best not to use during intense heat of the day.

Except "What are potassium salts of fatty acids? Potassium salts of fatty acids are produced by adding potassium hydroxide to fatty acids found in animal fats and in plant oils. Fatty acids are extracted from palm, coconut, olive, castor, and cottonseed plants to form this active ingredient *Potassium salts of fatty acids can be toxic to plants. Plants that have hairy leaves may hold the soap on their surfaces longer, resulting in a burn*" From Oregon State University. So potassium salts aren't so hot, either.

Would it be alright to use vinegar to kill the bugs in your fruit and vegetables plants that are planted in flower pots

This is the first video of yours I am seeing. I understand that chemists are intelligent people who understand chemicals however alot of chemicals that chemists claim are safe are infact dangerous. That's what I am saying. Look at Monsanto and Round up. Chemists made those formulas and claimed they were safe around humans when they really are not.

but in some of your videos, dishwashing soap like 2 drops with baby oil...now I am confused

does this really matter if you use that water to irrigate the ground rather than spraying it all over the leaves?

I just checked my Ivory dish soap... It says Dish Soap. I use it for medical supplies because it's gentle. My Palmolive says Dish Liquid.

so what do we use , also safe for animals around

Tocopherol is a form of vitamin E.

Can I use soap liquid made of Potassium hydroxide and olive oil only as a fertilizer?

I used dish soap mixed with vinegar and water it didn’t kill the plants

Please pin my comment so people may help me. Hello, I appreciate the information you provided. I followed some DIY videos and created a spray using the following ingredients: 2 tablespoons of dish soap, 2 tablespoons of olive oil, 1 teaspoon of baking soda, and 1 liter of water. I applied this spray around 11 a.m. in August when the temperature was around 35°C. I rinsed the plants after about an hour. However, I've encountered several issues since then. I've observed that the basil leaves have turned black, there are signs of leaf burns on my pumpkins and edamame plants, and new leaves on my pepper plants and other ornamental plants are growing curled. Additionally, the growth points on the pepper and other plants have turned black and appear burned. The tomato fruits display brown spots, and the edges of my mint plant have turned black and become wilted. The common symptoms I'm facing include curling of newly born leaves, leaf burns, and blackening/burning of growth points. I decided to use this spray to combat whiteflies, as I had heard that using chemical insecticides on plants might not be the best approach. I was worried that these insects would harm my harvest, so I chose this DIY solution. It's been a few days, and despite my efforts, the symptoms persist. This is why I'm reaching out through this video, seeking guidance and a solution. Your assistance is greatly appreciated.

What about Ivory bar soap?

Has to be biodegradable... ORGANIC is best...my grandfather showed me❤

Watch at 1.5x speed

Da! It’s says detergent next to it

Fear mongering at its finest. A surfactant is all that matters. Obviously don’t allow your plant to sit and dry in the heat covered in it. You wouldn’t do that your skin either would you? Common sense people.

I used it on my plants and everything is dying

I have said for more than a decade that Dawn marketing department were genius and were the first to realize the potential for free marketing on the internet. Every homemade recipe for . . . well, everything homemade . . . specifies that you have to use Dawn, more specifically, Blue Dawn. Any dish detergent would do the same in those mostly useless recipes. However, those recipes have sold a lot of Blue Dawn over the years. Many, many people do not use critical thought and struggle to tell the difference between marketing BS and fact. Thank you for posting this reality check. I lose my argument all the time with the Blue Dawn zealots.

Yeah ... Don't-Make-The-SOAP Out-of-'Dishes'!!!??? >(*U^)< (Joke) *Wink*

Tocopherol is Vitamin E.
