Coffee Waste as an Organic Fertilizer



We consume millions of cup every day where normally the waste from coffee we thrown it away. Except if we use the instant coffee than no more waste to be thrown. However, in lots of cases, these coffee waste or used coffee grounds are binned, tossed in the garbage or washed down the sink.

Most of the coffee shops throw away the waste, where if you have any ideas to collect it you could use it as fertilizer for free.

Used coffee grounds contain useful amounts of phosphorus and potassium are a low-level source of nitrogen and also contain minor amounts of calcium, magnesium, copper, and other trace minerals, carbohydrates, sugars, some vitamins as well as some caffeine.


Coffee grounds are not acidic as most of people claim it to be. The pH of used coffee grounds is approximately 6.8 to 6.9, with a significant amount of buffer capacity - adding the coffee to either acidic or basic solutions drove both towards neutral pH.

How to use it?                 

One of the best methods is to compost the used coffee ground and based on few results it shows best result when it was being composed. 


However if you don’t have those tools for your garden, you also could mix it with soil. Another alternative way is to make it as liquid fertilizer by mixing it with water. You have to test and make some experiment on your plant to know the suitable amount for it. No right formula for it since every different place has different soil and different pH. Good luck
