Uses for Used Coffee Grounds

In the spirit of making the most of what you have, here are some ideas for getting more use out of your used coffee grounds.

Garden

Used coffee grounds are particularly good for plants that love acidic soil. They can improve soil texture and drainage and contain nitrogen as well as trace amounts of various other elements. Used coffee grounds are better than unused coffee grounds for your garden as unused grounds are more acidic and contain much of the caffeine.

·        Soil Booster – Mix used coffee grounds in with your top soil or sprinkle directly on top of the soil around the plants. This is especially good for acid-loving plants, such as blueberries and hydrangeas. Be cautious with plants that do not love acidic soil.

·        Compost Pile – Coffee grounds can be added to your compost pile.

·        Pest Deterrent – Coffee grounds are said to help deter certain pests such as slugs, mosquitos, fleas, and wasps. Sprinkling on top of the soil is the best way to use it to deter pests.

 

Homemade Coffee Liqueur

We couldn’t find the recipe we originally used when we first tried this, but there were many things we would do differently anyway, so we searched for a couple of other options. We used vodka with the batch we made, but we would definitely try this with rum, as in the All Recipes option. Just a note: we dried the coffee grounds at a very low temperature in the oven before using in order to not dilute the recipe.

Mosquito Repellant

Dried coffee grounds can be used to repel mosquitos. Light a pile of dried coffee grounds in a fire safe dish. The smoke from the smoldering grounds helps to deter mosquitos.

 

Coffee Logs

Turn your used coffee grounds into logs to burn in your fireplace or campfire. These reportedly burn hotter than traditional dried wood. Some instructions use coffee grounds, wax, and molasses. Others use sawdust and coffee grounds or shredded paper and coffee grounds and create bricks by mixing them together with water, pressing out the water, and drying them thoroughly. The process for the latter seems a bit more involved than the recipe that uses wax, but it is good to have multiple options. We searched for instructions for several options and are posting them below:

·        Coffee and Sawdust Logs – YouTube This is a great video of how one YouTuber makes logs from sawdust, wood dust, coffee grounds, and water. The video is under 15 minutes and gives great detail.

·        Coffee, Sawdust, and Paper Logs – YouTube This video is super short, but gives you the basic idea of how to make the logs.

·        Coffee and Wax Logs This site shows you how to make a coffee log out of used coffee grounds, wax, and molasses.

·        Coffee and Wax or Cooking Grease Logs This page gives instructions similar to the one above, but gives an extra option for using used cooking grease in place of the wax.

·        Coffee and Egg Carton Mini Logs  This article gives you instructions for making mini coffee logs without wax using paper egg cartons.

 

Coffee Soap

You can use used coffee grounds in your next batch of homemade soap to add exfoliating properties to your bar. We found this recipe that looks promising. We can’t wait to try it!

Garden Update - Late Spring 2025

Outdoor Garden We set up the last garden bed that we didn't get to last summer. We purchased our third two-pack of the 6x3 beds last year and only set one of them up. I prepped the bed with cardboard and threw in some limbs, leaves, and grass clippings. I then topped it off with soil. We also did a bit of planting. Our larger bed has mint and tarragon on one side. They are healthy plants and come back every year, so I like to leave them alone. We planted a few flower seeds in the bare spots on this side. We planted dry beans on the other side using beans I had saved from a previous garden. The seeds are a couple of years old, so if they do not come up within a reasonable time, I will re-plant with newer seed. We also planted two of the shorter beds. This gives us four beds that are ready to go for the season: one of strawberries, two we just planted, and one with tarragon and mint on one side and the beans we just planted on the other. We will plant the remaining beds when the weat...

Indoor Garden Update

Our indoor garden has been in for one month now and we are so pleased with the progress! If you would like to read about our experience in setting up our indoor garden, you find the information on our blog post " Starting an Indoor Garden ." Our AeroGarden one month after planting Below is a progress breakdown by pod: Lettuce/Mixed Greens (1st pod)   The first pod of mixed lettuce greens we planted is doing fabulous . I can't tell if two of the same kind of seeds sprouted or if it is just one large plant. We have harvested several leaves already. The plant continues to grow well so we should get a good harvest from this pod. Lettuce/Mixed Greens (2nd pod)   The greens didn't come up at first in the second pod, so I added a couple more seeds and moved some of the sponge over the seeds since it hadn't really closed over them. I had no idea if it would help, I was just experimenting. They eventually sprouted and two plants are growing. Due to the delay in sprouting, ...

DIY Tooth Powder

We have been trying different options for better oral health. We already make a mouthwash that we like really well, so it was time to try making something else. We chose to make our own tooth powder. While most recipes claim these ingredients make a "re-mineralizing" tooth powder, we found that whether or not it re-mineralizes, this recipe gets your teeth sparkling clean. After reading through several recipe options, we came up with our own based on the ingredients we had on hand. Here is the recipe we created: Note: This blog post contains affiliate links.
