Creative Uses for Leftover Coffee Grounds: From Fertilizer to Odor Control

Leftover coffee grounds might seem like a waste at first, but they have numerous practical and creative uses. From repelling pests to improving soil health, these grounds can transform your household and garden into greener, more sustainable spaces.

1. Fertilizer for Plants

Used coffee grounds make an excellent fertilizer, especially for plants that prefer slightly acidic soil, such as hydrangeas. They provide essential nutrients to the soil and can improve its structure. Many people have been using coffee grounds as a natural soil conditioner for years, and their plants reap the benefits. These grounds can be mixed directly into flower beds or used in planters.

Interesting Fact: While used coffee grounds should go into the compost bin, our city council has advised their employees not to do so anymore due to the overwhelming amount of grounds collected in a week. The sheer quantity can spoil other compost materials, making the batch virtually unusable.

2. Repelling Pests and Slugs

One effective way to use coffee grounds is in the garden to repel pests and slugs. Their strong odor can deter many insects and small creatures from damaging your plants. Simply sprinkle the grounds around the base of plants or in areas where pests tend to gather.

3. Odor Control

Leverage the natural odor-neutralizing properties of coffee grounds to eliminate unwanted smells in your home. Place small bowls of dried coffee grounds in your refrigerator, gym bag, or shoes to absorb unpleasant odors. This is an eco-friendly and cost-effective alternative to reliance on commercial deodorizers.

4. Natural Cleaning Scrub

For a natural deep-cleaning solution for pots and pans, use used coffee grounds as a scrub. The grounds' texture and alkalinity help tackle tough stains and grime. Simply wet the grounds and use them to scrub away stuck-on food particles. Rinse thoroughly with water afterward.

5. Exfoliating Skin

Leftover coffee grounds also serve as a gentle exfoliant for your skin. Mix the grounds with a little water to form a paste. Apply it to your skin in circular motions and then rinse off. This technique can help remove dead skin cells and leave your skin feeling smooth and revitalized.

Reminder: If you decide to put coffee grounds in your compost bin, be sure to balance them with other types of compostable materials to avoid overwhelming the microbial activity.

By repurposing your leftover coffee grounds, you can reduce waste, save money, and cultivate a healthier, more sustainable environment. Whether you use them as a natural fertilizer, pest repellent, or odor absorber, coffee grounds have versatile applications that can benefit both your home and your garden.
