Are used coffee grounds useful for mixing with garden soil?

Question

I’m interested in planting some bushes and trees on my property (approx. one half acre in size).

Answer 1

They are useful for adding organic material to the soil which improves aeration, water retention and drainage. Used coffee grounds DO NOT increase the acidity level of your soil as many people think. That is only true of unused coffee grounds.

You can also add used coffee grounds to your compost pile to add nitrogen.
