You think coffee grounds are good for plants.
A quick internet search for “coffee grounds + plants” will draw up close to four million hits, with consistent claims they can add essential minerals to the soil, boost populations of friendly soil bacteria and even reduce the pH of growing media for acid-loving plants like rhododendrons.
The growth of pretty much everything in the coffee bed became noticeably worse in about two weeks of application.
Plant growth slowed, some developed leaf yellowing, others defoliated and died.
Seedling germination in some cases was almost completely inhibited.
While some species looked OK, none of the plants in the coffee group proved better than my basic control.
But it’s just adding organic matter.
It isn’t even always very acidic.
