So at my best guess I put 32 ounces of vinegar in the container and sprayed at a ration of 8 ounces to on gallon.
That would be 1 cup per gallon of 5% acidity vinegar.

I saw some agricultural vinegar at the store for a lot higher price and I said what the heck I'll use what I have.

I would have no idea about the boric acid but I think I saw some stuff with phosphoric acid in it for the same purpose.

They have a product that is for turning hydrangea blooms from pink to blue ad blue to pink.
One is acidic and the other is alkali.

You can also use sulfur to make soil acid.

Here is a link and a chart at the bottom of the page.

The whole thing was an experiment for me. I had no idea what I was doing and it worked.


Thank you much. I found one tomato today with BER so I am also trying to add calcium without disturbing the plant....would milk work? I'm unsure of what to use and how much to try to tweak my soil.
