Tips on Using Coffee Grounds in the Garden

Coffee Grounds

If you are an avid coffee drinker and a gardening enthusiast then here’s a great opportunity for you to kill two birds with one stone. In recent years, more and more people have onboarded the sustainability movement and one way to contribute is by re-using natural waste. Coffee grounds happen to be one good waste that can be used in the garden.

Coffee Grounds as a Natural Pest Control
Yes, coffee grounds may help potentially help deter common garden pests. It’s particularly useful when you are dealing with a slug or snail invasion. It could work because of the coarse nature of the coffee grounds. It’s simply too abrasive for soft-bodied insects like slugs to cross over.

Coffee grounds may also work against repelling ants, albeit temporarily. In summary, using coffee grounds as a natural pest control is a bit of hit-or-miss but it’s worth trying in tandem with other natural pest control methods if you want to stay away from using chemical pesticide.

Coffee Grounds as Natural Fertilizer
Coffee grounds is great for gardening because it happens to be a good natural fertilizer. The proportions of macronutrients will differ by coffee products but generally speaking, you can expect coffee grounds to contain about 2% nitrogen, 0.06% phosphorus, and 0.6% potassium. It’s great to use as a slow-release fertilizer. All you have to do is to sprinkle a thin layer of coffee grounds on top of the soil or you can also add some to the compost heap.

Coffee Grounds as Mulch
As some of us may know, mulch plays a very important role in gardening. It can help retain moisture in the soil and also play several other important roles like suppressing weed growth and preventing frost during the cold season. It just so happens that coffee grounds are an excellent material to add to mulch. Mixing coffee grounds with other organic matter can make an effective mulch. Coffee grounds is not acidic so you don’t have to worry about the acidic properties that are typically associated with coffee itself.
