Key Information: Coffee Grounds for Plants
- Nitrogen Content: Coffee grounds contain approximately 2% nitrogen.
- pH Level: Coffee grounds are slightly acidic, with a pH around 6.5.
- Suitable Plants: Acid-loving plants like blueberries, azaleas, and hydrangeas benefit most.
- Application Rate: Use sparingly, no more than 1/4 inch layer at a time.
You can use coffee grounds in several ways in your garden:
- Soil Amendment: Mix coffee grounds directly into the soil to improve drainage and aeration.
- Mulch: Spread a thin layer of coffee grounds around plants to suppress weeds and retain moisture.
- Compost Activator: Add coffee grounds to your compost pile to speed up decomposition.
- Pest Repellent: Sprinkle coffee grounds around plants to deter slugs, snails, and ants.

| Coffee Ground Mulch | Weed suppression, moisture retention, slow-release nutrients. | Can mold if not dried properly, may attract pests if too thick. | Protecting delicate seedlings and retaining moisture. |
| Coffee Ground Compost | Adds valuable nitrogen to compost, balanced nutrient release. | Requires mixing with carbon-rich materials, takes time to decompose. | Creating nutrient-rich compost for a variety of plants. |
| Coffee Ground Pest Repellent | Natural and non-toxic, easy to apply. | Needs reapplication after rain, may not be effective for all pests. | Deterring slugs, snails, and ants from gardens. |
Pro Tip #1: Drying Coffee Grounds
Always dry your coffee grounds completely before storing them or using them in your garden. This will prevent mold growth and ensure that they don’t clump together.
Home Hacks: Cleaning and Deodorizing
Coffee grounds aren’t just for the garden; they can also be used to clean and deodorize your home. Their abrasive texture makes them ideal for scrubbing, while their absorbent properties help eliminate odors.
Here are some ways to use coffee grounds around the house:
- Odor Absorber: Place a bowl of dried coffee grounds in your refrigerator, freezer, or car to absorb unpleasant odors.
- Pot Scrubber: Use coffee grounds to scrub stubborn food stains from pots and pans (avoid using on delicate surfaces).
- Drain Deodorizer: Pour coffee grounds down your drain followed by hot water to eliminate odors and prevent clogs.
- Furniture Scratch Repair: Make a paste of coffee grounds and water and rub it into scratches on dark wood furniture.
Pro Tip #2: Drain Cleaning Caution
While coffee grounds can help deodorize drains, use them sparingly. Too many grounds can contribute to clogs over time, especially in older plumbing systems.
Beauty Boost: Coffee Grounds for Skincare
Coffee grounds can also be used in your beauty routine. Their coarse texture makes them an excellent natural exfoliant, while the caffeine content can help reduce the appearance of cellulite.
Here’s how to use coffee grounds for skincare:
- Exfoliating Scrub: Mix coffee grounds with coconut oil or olive oil to create a natural exfoliating scrub for your face and body.
- Cellulite Treatment: Massage coffee grounds into areas affected by cellulite to improve circulation and reduce its appearance.
- Foot Scrub: Use coffee grounds to scrub away dead skin and calluses from your feet.
DIY Coffee Ground Exfoliating Scrub
- Collect Used Coffee Grounds: Ensure they are completely dry.
- Mix with Oil: In a bowl, combine 1/2 cup of dried coffee grounds with 1/4 cup of coconut oil or olive oil.
- Optional Additives: Add a few drops of essential oil (like lavender or tea tree) for added benefits and fragrance.
- Apply to Skin: Gently massage the scrub onto damp skin in circular motions.
- Rinse Thoroughly: Rinse with warm water and pat dry.
- Moisturize: Apply your favorite moisturizer to keep your skin hydrated.
Pro Tip #3: Patch Test First
Before using coffee grounds on your face or body, perform a patch test on a small area of skin to check for any allergic reactions or irritation.
Composting Coffee Grounds
Composting coffee grounds is a fantastic way to enrich your garden soil. Coffee grounds are considered a “green” material in composting, meaning they are rich in nitrogen. They need to be balanced with “brown” materials, which are rich in carbon, like dried leaves, shredded paper, or straw.
Here’s how to compost coffee grounds effectively:
- Mix with Brown Materials: Combine coffee grounds with an equal amount of brown materials to create a balanced compost mix.
- Turn Regularly: Turn your compost pile regularly to ensure proper aeration and decomposition.
- Maintain Moisture: Keep your compost pile moist but not soggy.
Pro Tip #4: Coffee Filters Too!
Don’t forget to compost your paper coffee filters along with the grounds. They are a great source of carbon for your compost pile.
