How do you use coffee grounds in the garden, if you do?
I haven't picked up any of the free bags at Starbucks, but I have begun recycling my own in the garden. With such a small amount, I'm just adding to old soil in beds I haven't used yet, and putting a bit beneath acid-loving plants. I'm also trying it out as an experiment on a small patch of grass in my yard to see what happens.

I might even take off the hard bits and put it through the blender with a bit of water. A summer smoothie for the garden!
I buy a larger coffee can with lid, and just save an empty one for keeping the collection under the sink. Once it's full I rinse it outside and THEN I put it in the recycling bin, and start a new collection with the next empty tin.
I am now saving the grounds and banana peels for the roses LOL
coffee grounds are a good source of nitrogen and it is avaliable to the plants over a longer period than cemmerical formulations, because it takes time for the grounds to break down. Not sure aobut them being acidic - pine needles are good for that. Banana peels are a terrific source of potassium -- remember the scene in the movie (sorry, senior moment! -- the one with Kevin Spacey where he may or may not be an alien) where he eats the banana peel? It has so much potassium it is toxic and apprently he had to be careful not to swallow too much of it but it took a lot of takes to get the scene. LOL, set my teeth on edge just thinking aobut eating the peels! Thereforee, banana peels are also good in compost. But either can be applied directly to the soil around the particualr plants you are interested in.
I know people who bury cut up banana peels around their roses, why ? I do not know.
I think roses take to coffee grounds. I might be dreaming, but I recall an episode of Three's Company where Mr. Furley had red roses that he grew with the help of coffee grounds.
I know years ago people added tea leaves and coffee grounds to the garden as a compost I guess. I know under Hostas grounds can keep slugs away from the plants. Other than that I am not familiar with their use.
