Ever wonder what can be done with used coffee ground beside discard it as waste? Here are some tricks for you to maximize your coffee value even after they provided you a cup a great joe and enrich your garden with this zero-waste solution !
Adding ground coffee into your gardening soil, be it sprinkle on the ground or scratch it into inches of soil. It’s usually very low in acidity as it was mostly extracted at your cup of coffee, so it shouldn’t cause any concern for increasing high acidity level for your plant. The benefit of using coffee grounds as a fertiliser is that it adds organic material to the soil, which improves drainage, water retention and aeration in the soil.
Besides, you can also create a “Coffee Tea” by steeping your ground coffee with water overnight ( 2 cups of used coffee ground with 18 litre, depend on your preference). Use it to water your garden as liquid fertilizer and it will be the great foliar feed you can spray on the leave and steam of plant
2. Keep the Pests Away
Create a slug and snail barrier. Coffee grounds are abrasive, so a barrier of grounds placed near slug-prone plants may just save them from these garden pests. However, be warned that some researchers quibble with this advice and don't think it is effective. You may want to have a backup plan in mind if it doesn't work. Many cats dislike the smell of coffee grounds and may avoid using your garden as a litter box if you mix coffee grounds into the soil.
3. Fresh Coffee Grounds for Acid-Loving Plants
While used coffee grounds are only slightly acidic, fresh (unbrewed) coffee grounds have more acid. Your acid-loving plants like hydrangeas, rhododendrons, azaleas, lily of the valley, blueberries, carrots, and radishes can get a boost from fresh grounds. However, tomatoes do not like fresh coffee grounds; keep them out of that area of the garden. This could be a good use for coffee that is getting old in your pantry or a type you bought for visiting friends but isn't your usual cup of joe.
Fresh coffee grounds still have most of their caffeine content as well as the acid. Be cautious in using fresh grounds around pets or your wire terrier may become extremely wired.

4. Composting with used ground coffee
Using your leftover coffee grounds for composting not only helps your compost heap turn leftover food, fruit and vegetable peelings into nutrient-rich garden soil, it also reuses something that would ordinarily be thrown away.
It is much simpler than you think, just throw your coffee bits straight onto your compost pile or throw them (straight from the pot) into your compost bin. The great new is coffee filters are biodegradable as well, so you won’t have to worry about scraping them clean to throw them away.
The leftover bits add nitrogen to your compost pile and will improve the makeup of your garden soil.
The important thing to remember when you are using used grinds for composting, is they are a green compost material – this means that they are high in nitrogen. Other green materials are grass clipping and vegetable peel. In a good compost heap, you want a balance between green compost material and brown compost material. Brown material is high in carbon and includes eggshells, leaves, paper and cardboard. By getting the balance right in your compost heap, and having an equal amount of both, you will make sure you get the best quality garden soil.

5. VERMICOMPOSTING – LET THE WORMS DO THE WORK
One creature that absolutely loves leftover coffee bits is worms. They are a gardener’s best friend and the use of worms for vermicomposting is a great way to enrich your soil and keep it full of nutrients. Earthworms turn organic waste into extremely high-quality garden soil. A family of worms is the best way to break down your compost heap and vermicomposting systems are a clean and efficient way to break down scraps and garden cuttings.
Worms need gritty food to aid their digestive system which is why the texture of grinds is perfect for them. Their internal organs are helped by the addition of organic grinds which makes them better at munching their way through your compost heap.
