Gardening enthusiasts often think about using coffee grounds to improve the overall health of their plants. You might have heard about the practice of using coffee grounds in your garden as well. But is it really helpful or harmful?
Opinions on this topic are divided. While some gardeners swear by using coffee grounds to grow plants, others believe it to be the worst thing you can do for your garden. If you’re wondering which side to trust, we’ve got you covered.
In this blog post, we’ll discuss whether or not coffee grounds are good for your garden and how you can use them to get the most out of it.
Are Coffee Grounds Good for your Garden?
Quick answer? Yes, coffee grounds can be good for your garden. Why? Because they contain high levels of nitrogen, which is essential for plant growth and can help increase soil fertility. Not to mention, coffee grounds can attract beneficial earthworms to your garden, which can help improve soil structure and overall health.
However, it’s important to add coffee grounds in moderation. Too much coffee can create an acidic soil environment, which can be harmful to some plants. It’s recommended to use coffee grounds as a supplement to other fertilizers, rather than relying on them as the sole source of nutrients.
It’s important to note that not all plants benefit equally from coffee grounds. Acid-loving plants like azaleas, rhododendrons, and blueberries can benefit from coffee grounds, but other plants like tomatoes, lettuce, and peppers may not thrive as well with coffee grounds.
It’s always a good idea to research which plants in your garden can benefit from coffee grounds before using them.

Use them as a Soil Amendment
Coffee grounds add organic matter to the soil, which improves soil structure, water retention, and fertility. You can surely use them as a soil amendment, providing numerous benefits to your garden. As a natural fertilizer, coffee grounds are rich in nitrogen, which promotes healthy plant growth.
As mentioned earlier, coffee grounds can also improve soil structure and drainage, creating an environment that is ideal for plant growth. When you use them as a soil amendment, it retains moisture in the soil, reducing the amount of water needed for your plants.
They can also help to regulate soil pH, which can be especially helpful for acid-loving plants. By incorporating coffee grounds into your soil, you can create a healthier and more productive environment for your plants to thrive in.
Besides, if you’re planning to lay turf, improving the quality of the soil will improve the effectiveness of your turfing efforts. For more information, seek advice from our turf laying service providers in London.
Use them to Improve the pH balance
Coffee grounds are slightly acidic, which can help to balance the pH level of alkaline soils.
You can use coffee grounds as a natural way to adjust the pH balance in your garden. Research has shown that coffee grounds are slightly acidic, with a pH level of around 6.2, making them a great option for those looking to lower the pH level of their soil.
Adding coffee grounds to your soil will make it more acidic, which can be especially beneficial for acid-loving plants like blueberries, azaleas, and rhododendrons. Besides, coffee grounds can also help you regulate the pH balance in your soil over time, creating a more stable environment for your plants to thrive in.
While coffee grounds can be helpful in adjusting soil pH levels, you can use them in moderation. Just make sure to add coffee grounds sparingly and mix them well into the soil to avoid creating concentrated areas of acidity. With proper use, however, coffee grounds can create a healthy environment for your plants to grow.
Using Coffee As Fertiliser
Did you know that you can use your coffee grounds to give your plants a nutrient boost? They contain nitrogen, phosphorus, and potassium, which are essential nutrients for plant growth.
Experts suggest using dregs as fertilizer to reduce waste. Simply sprinkle the grounds onto your soil and rake them in lightly. You can also create a liquid plant fertilizer using leftover diluted coffee.
It is recommended to mix two cups of brewed coffee grounds with five gallons of water in a bucket overnight. This will give your plants a slow-release dose of nutrients, and it’s an easy way to repurpose your leftover coffee.
Use them for Pest Control
Did you know that coffee grounds can be used to keep pests out of your home and garden? Sprinkling them on the soil can deter slugs, snails, and ants, which can harm plants.
Ants, in particular, are not fans of such food items due to the damage they can cause to their exoskeletons.
To keep ants out of your house, try laying down a 2 inch wide line of spent coffee grounds around the foundation and entrances. You can use the same technique against worms, snails, slugs, and other insects.
For plants, you can create a similar line or mix the coffee grounds with hot water and pour the solution over anthills. This will help you get rid of fleas, but be sure to keep it away from your pets, as they may not appreciate a coffee shower.
Using coffee grounds as a natural pest control method, you can avoid harsh chemicals and keep your home and garden free of unwanted visitors. One of our blog posts offers valuable tips for improving the soil quality and preparing the ground.
Coffee grounds as a Compost accelerator
Adding coffee grounds to a compost pile can speed up the decomposition process and improve the quality of the compost. If you’re looking for a natural way to accelerate your composting process, look no further than your morning coffee.
A balance of “greens” and “browns” is essential for successful composting. Greens are nitrogen-rich materials, such as fruit and vegetable peels, dried leaves, and used coffee grounds, which provide microorganisms with the nutrients they need to grow and reproduce. Browns, on the other hand, are carbon-rich materials, such as dried leaves, twigs, and newspaper, which give microorganisms the energy they need.
To create the ideal composting environment, aim for a 1:4 ratio of greens to browns. Too much green material can cause your compost pile to smell, while not enough green material will prevent the microorganisms from generating enough heat to break down the compost.
After about three months, your organic material will have been transformed into nutrient-rich compost, which you can use to give your plants a much-needed boost. By repurposing your used leftover, you can create a natural and effective compost accelerator for your home garden.
Coffee Grounds As Mulch
You can also use them as mulch to help retain moisture in the soil and suppress weeds. You can use them as a type of mulch by mixing them with other organic materials, like shredded leaves. Mulching helps to prevent moisture from evaporating from the soil and regulate soil temperature.
It can also prevent weed growth, as the mulch acts as a physical barrier to weed seeds and prevents light from getting through. However, when using dreg as mulch, it’s important to mix them with other materials to prevent compaction and ensure water can still penetrate the soil.

Final Thoughts
If you’re a fan of filtered coffee, don’t toss your leftover coffee grounds! Collect them in a large container and use them to benefit your garden. Simply mix the grounds with your soil or other organic materials like shredded leaves or lawn clippings to make a mulch. This will not only help reduce waste but also provide your plants with a nutrient boost.
If you usually drink instant coffee, consider switching to filtered coffee to collect grounds for your garden or ask your local coffee shop for their used grounds. Remember to always mix them with other organic materials to avoid compacting and prevent water from reaching the soil.
