Back when I had my outdoor kitchen next to the shade garden, I dumped the ash from the grill and the coffee grounds in a pile together right there in the shade garden... reckon the wood ash took care of whatever acidity the coffee grounds might have contained.
I checked the article....
I didn't see the point in even writing it...
when we dump the coffee grounds in the compost, and add whatever other kitchen scraps, plus the plants that get pulled out of the garden and whatever else... it really doesn't matter how acidic or alkaline anything is... it all balances out.
