Plant Fertilizer
Used coffee grounds are an excellent and sustainable plant fertilizer, providing essential minerals and nutrients for plant growth. These grounds contain nitrogen, potassium, phosphorus, and other elements that are beneficial for plants. When added to the soil, coffee grounds can release these nutrients slowly, promoting healthy root development and overall plant health.
To use coffee grounds as a fertilizer, simply sprinkle them around the base of your plants and lightly mix them into the soil. Avoid piling up large amounts of coffee grounds in one area, as it may create a compacted layer that can hinder water penetration. Additionally, coffee grounds are particularly beneficial for acid-loving plants like azaleas, blueberries, and roses, as they help to acidify the soil.
It is important to note that coffee grounds should be used in moderation and mixed with other organic matter. Using too much coffee grounds can make the soil too acidic, which may negatively affect the plants. Therefore, a balanced approach is recommended to ensure optimal plant growth.
Composting Material
Did you know that coffee grounds make a fantastic addition to compost piles? Incorporating coffee grounds into your compost can significantly improve soil health and reduce greenhouse gas emissions. As coffee grounds decompose, they introduce organic matter to the compost, enriching it with beneficial microorganisms.
Coffee grounds are considered a “green” material in composting, meaning they are high in nitrogen. Nitrogen-rich materials provide the necessary energy for microorganisms to break down organic matter. As a result, the decomposition process is accelerated, and the compost becomes rich in nutrients.
To effectively use coffee grounds in composting, mix them with an equal amount of “brown” materials such as dried leaves, newspaper shreds, or straw. This helps create a balanced carbon-to-nitrogen ratio and ensures proper decomposition. Remember to turn your compost pile regularly to allow for oxygen circulation, which enhances the decomposition process.
Pest Repellent
Using coffee grounds as a natural pest repellent can be an effective and eco-friendly way to keep insects and pests at bay. Coffee grounds have a strong scent that repels creatures like mosquitos, fruit flies, beetles, slugs, and snails.
To use coffee grounds as a pest repellent, simply:
- Sprinkle them around areas where pests are likely to gather or enter, such as the perimeter of your garden, patios, or window sills.
- Create a concentrated solution by steeping coffee grounds in hot water and then spraying the resulting liquid in areas affected by pests.
It is important to note that while coffee grounds can be effective against certain pests, they may not eliminate them entirely. Therefore, it is recommended to combine coffee grounds with other pest control methods for maximum efficacy.
Skin Exfoliant
Aside from their benefits in the garden, coffee grounds can also be utilized in your skincare routine. As a natural exfoliant, coffee grounds can help remove dead skin cells, leaving your skin feeling refreshed and rejuvenated. The coarse texture of the grounds helps to slough off dry and flaky skin, revealing a smoother complexion.
To use coffee grounds as a skin exfoliant, mix them with a carrier oil like coconut oil or olive oil to create a paste. Gently rub the mixture onto damp skin in circular motions, focusing on areas that need extra attention, such as elbows, knees, and feet. Rinse off with warm water and follow up with a moisturizer to lock in hydration.
It is worth mentioning that coffee grounds should not be excessively scrubbed onto sensitive or irritated skin, as they may cause further irritation. Additionally, always patch test any new skincare products to ensure you do not have any adverse reactions.

- Patch test new skincare products to avoid adverse reactions.
Weed Control
Coffee grounds can be used as a natural and eco-friendly mulch to control weeds in your garden. When applied around plants, coffee grounds act as a barrier that helps suppress weed growth by preventing sunlight from reaching weed seeds and depriving them of the conditions they need to germinate.
To use coffee grounds as a weed control method, distribute a layer of grounds around the base of your plants, making sure not to pile them up directly against the stems. Reapply the coffee grounds regularly, as they break down over time and may need replenishing.
In addition to suppressing weeds, coffee grounds can also help retain moisture in the soil and improve its overall structure. This means less water evaporation and healthier plants in the long run.

A natural plant fertilizer for your garden. The nutrients in coffee grounds, such as nitrogen, potassium, and phosphorus, can help nourish the soil and promote healthy plant growth.
-
A composting material. Coffee grounds are high in organic matter, which makes them a valuable addition to compost piles. They can help speed up the decomposition process and enhance the nutrient content of the compost.
-
A pest repellent. Some pests, like slugs and ants, dislike the smell of coffee grounds. By spreading them around your plants or at entry points, you can deter these unwanted visitors from your garden.

Frequently Asked Questions
What can you do with used ground coffee?
Used ground coffee can be repurposed in various ways beyond just making a cup of joe. For instance, it can be used to clean your fireplace, as the abrasive texture helps remove dirt and soot. You can also create a coffee firelog by combining used grounds with wax, providing a unique scent when burned. Additionally, the natural grittiness of coffee grounds makes them effective as a cleaning scrub for removing grime from various surfaces. Another interesting application is using coffee grounds to touch-up furniture scratches, thanks to their dark color that can blend well with wood tones. Furthermore, coffee grounds can be utilized as a natural dye, producing earthy hues on fabrics or paper. Considering their tenderizing properties, coffee grounds can also be used as a flavor-enhancing meat tenderizer. Lastly, coffee grounds can act as an insect repellent and help de-frost and de-ice surfaces.
Which plants do not like used coffee grounds?
While coffee grounds can benefit the growth of soybeans and cabbage, certain other plants do not appreciate their presence. Several examples include geranium, asparagus fern, Chinese mustard, and Italian ryegrass. These plants are negatively affected by the inhibitory properties of coffee grounds and may experience hampered growth or development when exposed to them. It is crucial to consider the specific preferences and tolerances of different plant species when deciding whether or not to use coffee grounds as mulch or compost.
Are used coffee grounds good to eat?
Coffee grounds can be consumed, but it is important to note that they are not commonly consumed directly as a standalone food. While they still contain some caffeine, antioxidants, and dietary fiber, the taste and texture may not be pleasant for most people. However, coffee grounds can be repurposed in various creative ways, such as using them as a flavoring agent in baked goods or as an ingredient in skincare products. So, while they are technically edible, it might be more enjoyable and beneficial to explore alternative uses for coffee grounds rather than consuming them directly.
Are used coffee grounds good for all plants?
While used coffee grounds can be beneficial for some plants, they may not be suitable for all types of plants. The grounds are a good source of nitrogen, which helps with leaf growth, but they lack other essential nutrients that plants require for overall health. Therefore, it is recommended to supplement the use of coffee grounds with other fertilizers or fresh potting mix to ensure that your plants receive all the necessary nutrients for optimal growth.
while using used coffee grounds as a fertilizer for houseplants can be a helpful addition, it is important to remember that it may not provide all the necessary nutrients. Supplementing with a premade houseplant fertilizer or fresh potting mix will ensure your plants have all the nutrients they need to thrive and be healthy.
