Using used coffee grounds for fertilizing home garden

Many Uses of Used Coffee Grounds in Your Garden & Around the Home

Coffee is a favorite morning beverage for many, but what happens to the used coffee grounds after that last sip? Surprisingly, used coffee grounds can have many uses in your garden and around the home.

In the garden, used coffee grounds can be used as a natural fertilizer, pest repellent, and soil amendment. Coffee grounds are rich in nitrogen, phosphorus, and potassium, making them an excellent fertilizer for plants that require an acidic soil environment, such as blueberries, azaleas, and rhododendrons. The high nitrogen content in coffee grounds also makes them an effective pest repellent against slugs and snails. Simply sprinkle the coffee grounds around the base of plants to create a barrier that these pests will avoid.

Used coffee grounds can also be added to compost bins to increase the nutrient content of the compost. Coffee grounds are considered a green compost ingredient, which means they are high in nitrogen and can help balance the carbon-to-nitrogen ratio of the compost. The high acidity of coffee grounds can help break down organic matter in the compost, resulting in a nutrient-rich soil amendment for your garden.

In addition to their uses in the garden, used coffee grounds can also have many applications around the home. They can be used as a natural deodorizer for the refrigerator or as a cleaning agent for pots and pans. The coarse texture of coffee grounds makes them an effective abrasive for scrubbing away stubborn stains, and their natural acidity can help remove grease and grime.

Used coffee grounds can even be repurposed for beauty and skincare uses. The caffeine in coffee grounds has been shown to have anti-inflammatory properties, making them a popular ingredient in homemade face masks and body scrubs. The coarse texture of coffee grounds can also help exfoliate dead skin cells, leaving your skin feeling smooth and refreshed.

Fertilize garden using used coffee grounds

2. Fertilize Your Garden

As mentioned earlier, coffee grounds are high in nitrogen and make a great fertilizer. Mix used coffee grounds into the soil in your garden or sprinkle them around the base of plants to help them grow healthy and strong.

Fertilizing your garden with used coffee grounds is a simple process that can help improve the health of your plants.

Here’s how to do it:

  1. Collect your used coffee grounds. You can either collect them from your own coffee pot or ask a local coffee shop if they have any to give away.
  2. Let the coffee grounds dry out for a few days. Wet coffee grounds can clump together, making them difficult to work with.
  3. Sprinkle the dried coffee grounds around the base of plants in your garden. Be sure to spread them out evenly to avoid creating clumps.
  4. Work the coffee grounds into the soil using a gardening fork or rake. This will help the nutrients from the coffee grounds to penetrate the soil and be absorbed by the plant roots.
  5. Water the plants as you normally would. The water will help the coffee grounds break down and release their nutrients into the soil.
  6. Repeat the process every few weeks throughout the growing season. This will help keep your plants healthy and strong.

It’s important to note that coffee grounds are acidic, so they should only be used on plants that prefer an acidic soil, such as azaleas, blueberries, and rhododendrons. If you have plants that prefer a neutral or alkaline soil, it’s best to use a different type of fertilizer. Additionally, coffee grounds should be used in moderation, as too much can make the soil too acidic and harm the plants.

Composting using used coffee grounds
