Coffee grounds are one of the kitchen wastes and business, which can be recycled in the garden. So then, the discussion becomes how to use the coffee grounds. Using coffee grounds in the garden, basically, come down to composting. There several approaches to composting, which can be applied to coffee grounds.
The Value Of Coffee Grounds As Fertilizer
- The three principal nutrients by which the value of fertilizer is typically measured are; Nitrogen (N), Phosphorus (P), and Potassium (K). Measured by those nutrients, Coffee grounds do have value as a fertilizer when used as compost or applied directly as a soil
The NPK Value of Coffee Grounds

How Much Coffee Grounds To Use
- When using coffee grounds as compost or when applied directly as a soil amendment, the volume of coffee grounds should be limit to more than 20 percent of the soil or mix to which it is being added. This rule applies to sheet, trench, and/or postal composting.
Coffee Grounds As Mulch
- Coffee grounds are generally, fine ground and easily compacted so much so that they can form a barrier not allowing air and water to pass through your mulch. For this reason, coffee grounds are generally not recommended for use as mulch.
Sources of Coffee Grounds
From you Own Kitchen
- An obvious source of coffee grounds as your own kitchen, Americans tend to drink coffee nearly every day so rather than throwing your coffee grounds in the trash toss minute compost bin and use of her garden fertilizer.
From Your Local Coffee Shop Or Restaurant
- If you’d like to have more coffee grounds or you’re not getting enough coffee grounds for your purpose from your own kitchen, there are several local opportunities to acquire coffee grounds. In my local area, there are coffee shops like Starbucks or on the grind from which coffee grounds can be readily obtained. As a matter of fact, I’ve seen signs in the local Starbucks saying to ask the barista for coffee grounds for your garden. However, coffee shops may be an obvious choice, but there are any number of restaurants and cities and towns which can be taken advantage of with a little creative negotiation with the owner-operators.
