My houseplants and I have something in common, we both love coffee! I give left-over coffee to our houseplants, and they love it! It’s the number 1 thing I do with leftover coffee, and it has nothing to do with me drinking it!
Yes! Diluted coffee is an all-natural fertilizer for houseplants.
Do you always have leftover coffee sitting in the coffee maker? Or, are you like me, who orders a grande iced coffee and somehow leaves it on my desk, and then I find it the next morning feeling guilty for wasting $6!?
Did you know you can use your leftover coffee when watering your houseplants for extra nutrients? It’s True! Leftover coffee can be used as an organic fertilizer for your houseplants, and I highly recommend it! Just dilute it and use it!

I started watering my houseplants with diluted leftover coffee last year, and they went from happy to absolutely thriving!
I got the idea because I was curious about how the leftover coffee (and coffee grounds) contributed to our compost pile in the backyard. I throw as much as possible in our prairie area, and what doesn’t get eaten by the rabbits has helped with the growth of wildflowers.
I researched and found that coffee grounds and leftover coffee are a great source of nitrogen for your soil. Nitrogen is important for houseplants because it helps them produce more leaves & stronger stems. Coffee also contains calcium and magnesium which are also great for houseplants. I am so happy that I found this inexpensive natural fertilizer with something I have in my house every day!
You may be asking, do you just pour the coffee directly into your houseplants? Nope! I dilute it and I make sure it is at room temperature.
My golden ration mixture is 1 Part Coffee to 5 Parts Water.
Coffee can be pretty acidic which can potentially be dangerous for your houseplants. The diluted coffee should be the color of a weak or watered-down iced tea. Be sure to wait until the coffee has cooled so that you do not burn & shock your houseplants.
I water my plants with diluted coffee about once every 2 weeks, and they all seem very happy when I do! My Fiddle Leaf Fig has been growing lush new leaves like crazy since I started the coffee watering regiment. Same with my Varigated Rubber Tree – I bought it from a houseplant seller in California, and my diluted coffee really helped it “perk” up after its trip via USPS all the way to Wisconsin!
Have you given your houseplants coffee? Did you notice a difference?
I use the diluted coffee fertilizer on my ficus, rubber trees, umbrella tree, dwarf umbrella plants, monsteras, spider plants, snake plants, and fiddle leaf figs. I do not use it on my cacti, succulents, or calatheas. I also use the coffee fertilizer in our container garden, veggie and herbs, and our raised planter garden in the summer.
