using Coffee grounds in the garden
When using coffee grounds in the garden, do they need to be used? I got some coffee which turned out to be awful to drink. I wanted to use the raw or unperked coffee grounds in the garden. Do I need to actually "use" the grounds first, or can I use them as is?
Unbrewed coffee should not be used because they are more acidic and so rich in nitrogen that they could potentially burn plants.
