I would like to thank the Triad Women’s Blogger Network and McDonald’s of the Triad for inviting me to attend this weekend’s Earth Day Event. I enjoyed learning more about the Good Neighbor, Good Grounds coffee recycling program, and how it’s being implemented in my area.

McDonald’s was so kind to offer prepared jars of used coffee grounds for attendees to take home. I took home two.

As you can expect, I am delighted and appreciative. This post highlights my experience and some well-known reasons for using coffee grounds in your garden. My opinions are shared without bias.


Do you garden?

Yea, me too.

Grin. I’m pretty excited about being able to say that I have a garden. I’ve had opportunities in the past to participate in community or company gardens, but this one – the current one that keeps my hands dirty and my mind preoccupied – is all mine.

Well, almost all mine…

To be 100% transparent – I’m co-gardening with my neighbor, but the plant plot is on my property.

If you haven’t heard about the adventures of Mr. J. and Me, well…I’d encourage you to take a look.

The Plethora Pointe Plant Plot…

…that’s what I like to call it in my mind.

But I digress.

This weekend, as a part of my participation in the Earth Day Event with McDonald’s of the Triad, I was reminded that used coffee grounds are a GREAT way to give your garden a boost.

I drink coffee every day.
ALMOST. EVERY. DAY.

And what have I been doing with those grounds?!

I came home from the event and Mr. J. caught me out spending time with the little baby plants. I showed him my two jars from the event and he was surprised. He didn’t realize you could add used coffee grounds to the soil to fertilize it. He told me that he would start saving his grounds immediately.

“Me too,” I told him.

7 Reasons to Use Recycled Coffee Grounds in Your Garden

1. Coffee grounds can be used to help kill weeds

Who likes weeding the garden?

Good. Those of you who raised your hands…feel free to come over to my garden anytime!

Using coffee grounds isn’t a magical weed killer, but incorporating grounds as a part of your mulch can help control the the growth you don’t want.

2. Coffee grounds serve as an excellent fertilizer

If you don’t want to add coffee grounds to your compost – or like me, haven’t gotten around to composting yet – you can use coffee grounds as fertilizer by working it into the soil around your plants.

That’s what I did. As I added the new baby plants to the big garden area, I tipped a handful of coffee grounds into the spot I was digging up, worked it in and then planted the new plants – in this case, spinach and okra.

3. Coffee grounds add minerals to the ground, which in turn help your plants

When grounds decompose, they release nitrogen, potassium and phosphorus, which all support plant growth.

Spinach is one of the plants that is particularly keen on this kind of added boost, which makes me happy. I love fresh spinach – even better, the kid loves fresh spinach. Growing these little leaves will make this household very happy.

4. Coffee grounds add organic material to the soil

Adding organic material helps enrich the soil. It improves drainage, water retention and aeration.

All important things to growing great plants – and good food.

Is it wrong that I refer to my baby plants as my future food? You’re doing great, little guys! Keep growing.

5. Recycled coffee grounds also helps to feed worms

Earthworms love to feed on used coffee grounds because it helps them grow and reproduce.

Normally, I’d be like ewww….but it’s important to have worm activity in your soil to mix it up and help in mineralizing your vegetation.

As Mr. J. and I have worked the soil together to prepare and plant, we’ve noticed some earthworms. I’m a big fan of encouraging more worm activity, as I know it helps support healthy plants (also known as healthy future food).

6. Coffee grounds help repel troublesome insects

As excited as I am about encouraging earthworm activity, I am equally so when it comes to keeping troublesome insects away. The caffeine in the grounds acts as a poison absorbed through slugs’ and snails’ skin, and they’ll avoid it.

And the smell, which is SO ALLURING to me in the mornings, is not so in the case of insects like ants, slugs and snails. To them, it is not an aroma, it’s an odor; and works as a repellent.

7. Utilizing recycled coffee grounds is good for the environment

When coffee grounds are dumped into landfills they create methane, which is a greenhouse gas. Methane can be very harmful and is a cause of global warming.

By recycling the grounds, we are helping reduce greenhouse gas emissions and improving the overall quality of our air and water.
