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.

Using Coffee Grounds in the Garden.

Using Coffee Grounds in the Garden - Uses for Used Coffee Grounds in the Garden:
Coffee grounds are approximately 1.45% nitrogen. They also contain magnesium, calcium, potassium, and other trace minerals.
There are several ways you can put used coffee grounds to work in your garden:

- Put coffee grounds in your compost bin. As noted above, they are a valuable source of nitrogen.
- Add grounds directly to the soil in your garden. You can scratch it into the top couple inches of soil, or just sprinkle the grounds on top and leave it alone.
- Create a slug and snail barrier. Coffee grounds are both abrasive and acidic, so a barrier of grounds placed near slug-prone plants may just save them from these garden pests.
- Make coffee ground "tea." Add two cups of used coffee grounds to a five-gallon bucket of water. Let the "tea" steep for a few hours or overnight. You can use this concoction as a liquid fertilizer for garden and container plants. It also makes a great foliar feed.
- Add coffee grounds to your worm bin. Worms love coffee grounds! Add some to your worm bin every week or so. Just don't add too many at once, because the acidity could bother your worms. A cup or so of grounds per week for a small worm bin is perfect
