First time poster, appreciate any help/direction. In an attempt to try to cut out major chemicals from commercial fungicidal soaps to get rid of aphids and pests, I tried using one of MANY recipes for making one at home.

It included vegetable oil, a few drops of dish soap without any bleach or fragrance (I used seventh generation), and a dab of apple cider vinegar. I used a test portion of the plant and spray lightly at night.

Over the past two days it started to turn extra dark green and dry out the leaves and turning black/gray...definitely killing the plant. What have I done??

Is there anyway to counteract or am I done in? Should I remove the dying limbs?

Thanks for all your help!

Oil, drops of dish soap and water would have done fine. Most people use vinegar to spray and kill weeds!

Depends on how much vinegar.

Let's hope that it was not too much!!

Not only is vinegar an herbicide, but oils used during summer temperatures and in hot sunshine can cause plants to burn. Oils have to be used very carefully during the hotter seasons.

So I've basically made fried green tomatoes 😂

What a rookie mistake. I've attempted to water it out/off to prevent any further dehydration/oil burn. I have high hopes since we had a bit of rain the past couple nights since applying, but the damage may have been done (as you can see from the pics).

The other tomatoes are still covered in aphids and I decided to simply use Garden Safe insecticide.

Today is going to be warm and sunny though..should I cover the affected plant to keep it from getting further burnt?

What's done is done. The air getting to it may be more beneficial then covering with.

You have to remember that vinegar is acetic acid. Acids and plants are not generally a good idea! Citric acid, hey a slice if fresh orange in my whiskey sour is fine as a garnish.
