coffee grounds

Did you know that you can give house plants a “lift” by lining the bottom of pots with coffee filters full of used grounds?

To use coffee grounds as fertilizer, work the coffee grounds into the soil around your plants. Leftover diluted coffee works as a fertilizer as well.

Coffee isn’t what one would consider nutritional. But the organic matter is a notable source of nitrogen, potassium, phosphorus, magnesium and copper for your plants.

Coffee Grounds Lowers Soil pH:

If you rinse your used coffee grounds, they will have a near neutral pH of 6.5 and will not affect the acid levels of the soil.


To make a potting mixture, mix equal parts coffee grounds and topsoil. If you’re adding straight to flower beds just sprinkle it on top.

Make sure you don’t layer it thicker than half an inch. Use a small fork or rake to spread the coffee grounds evenly and mix it in with the top layer of your flower bed.

  1. I had heard that coffee grounds were beneficial in the garden but had no idea how to really use them. Thank you so much for this post. My used coffee grounds will be put to good use as well as the leftover coffee (when I have any). What a neat post. Thank you.

  2. Brenda a few years ago I had hollyhocks planted off of the back porch. I dumped the coffee pot and grounds on to the plant and I forget how big it grew exactly ( without searching through my blog ) but I recall that it was over 20 feet! 🙂
    So you are right, lol!
