15 Ways to Reuse Coffee Grounds

15 Ways to Reuse Coffee Grounds

Oh, coffee! Many of us rely on you to start the day or help us push through that early afternoon slump, but what happens to those coffee grounds after we finish the pot?

When you toss coffee grounds into the trash, they break down and release methane, like any other organic matter would do. Methane is a greenhouse gas 20 times more powerful than CO2. Luckily, there are lots of ways to divert all of that coffee from the landfill by using it in beauty products, cleaning supplies, and even in the garden!

For many of these tips, moist ground will do (just let them cool, so you don’t burn your skin!). If you’re planning to hang on to the grounds, though, you have to dry them out or they’ll get moldy. Dry them out by spreading a thin layer on a cookie sheet and placing them in a sunny spot to dry. When they’re all dried out, they’re ready to re-use!

Ready to start repurposing those old coffee grounds? Here are 15 tips to get you going! If you have more ideas on how to reuse coffee grounds, I’d love to keep the inspiration going in the comments.

1. Use them as fertilizer on acid-loving plants (like tomatoes and carrots)
2. Deter cats from the garden by sprinkling around beds or pots.
3. Mix with mashed avocado for an invigorating face mask.
4. Scrub your hands with spent coffee grounds after chopping onion or garlic to get the smell off of your skin.
5. Compost them.

Me and my family have been using coffee grounds for fertilizers for plants!
It really does a good job by keeping the lovely cats who enjoys urinating on our plants! =)

Great tips, thanks!
Coffee can also be used to darken hair if you have some leftovers. Just rinse through your hair after washing. Or let the used coffee grounds soak in some apple cider vinegar for a couple of weeks, then strain and dilute 1 part vinegar with about 6 parts water and rinse your hair (no need to wash out).

I have been using the grounds to put around roses and azaleas for a while, and they always give the roses a great boost! My son has some wonderful old camellia bushes in the yard of their rental home, and has been feeding them with grounds to good effect, as well.

The other thing I reuse from the house to the garden, is the mopping water. I mop with water with a cup of vinegar in it, and pour it on the azaleas and roses as well. Very appreciated by the plants, as I always get a lovely flush of flowers afterwards!
