 What? Oak Trees Produce Acid?

 

 

Do you have oak trees near your house? Have you noticed that the gutters have corroded rather quickly? Your oak trees are filled with oak galls containing tannin. Tannin is a very corrosive liquid when mixed with water, forming tannic acid that will eat through metal. Seriously.

In a relatively short period of time, your gutters could look like this.

I believe that vinyl is okay Wonderwoman Peg.

If someone still wanted a metal gutter, aluminum would be non-corrosive to the tannic acid.

I'm thinking that people aren't too concerned about the tannins in the wine.  :)

There are many, many oaks here in Connecticut. I have wondered about the effects of the tannin's on the house. We use aluminum for gutters, so not an issue.

Ever stop to think about the effects of tannic acid on the fasteners and support brackets used in decks James?

Thanks for the comment!

Tom, That's good stuff, I think the tannin is a defense mechanism of the plant to make its leaves less digestible. I think they will produce more tannin's if the tree senses attack. So you can have varying degrees of tannin production.

I was not aware of the tree defensive ability, the wonders of nature.

It sure beats wielding swords!

Enjoy this day Donald.
