Are Coffee Granules Good For Houseplants. Help Your Houseplants Thrive with Coffee and Kitchen ScrapsHeres How Sure you can compost most vegetable peelings and other kitchen waste but a few items like used coffee grounds can go straight from the counter to your houseplants.

For used coffee grounds any water you put in the filter while making coffee also removes acidity.
