Are Coffee Grounds Good For Geraniums

Hook: Have you ever wondered what to do with your used coffee grounds?

I know I have. After consuming my daily dose of caffeine, I always felt guilty about throwing away the leftover coffee grounds. It wasn’t until I stumbled upon a gardening article that I realized coffee grounds could be used as a natural fertilizer for my plants, including geraniums.

Thesis: Coffee grounds are not just for brewing a delicious cup of coffee, they can also be beneficial for your geraniums.

As a plant enthusiast and avid coffee drinker, I was ecstatic to learn about this eco-friendly and cost-effective method of plant care. But let me tell you, not all plant experts agree on the use of coffee grounds in gardening.

Some argue that it can harm plants while others swear by its benefits. So, in this article, let’s dive into the benefits of using coffee grounds on geraniums and how to use them effectively.

Preview of main points: In this article, we will explore the benefits of coffee grounds for geraniums and how to use them effectively.

Firstly, we’ll look at some key benefits that make coffee grounds a great addition to your garden soil – from being nutrient-rich soil amendments to acting as natural pest deterrents. Then we’ll examine how you can incorporate used coffee grounds by composting or topically applying it to your geranium plants. Let’s debunk some myths surrounding the use of coffee grounds in gardening before concluding whether it is truly good for our beloved geraniums or not.

Benefits of Coffee Grounds for Geraniums

Nutrient-rich soil amendment

Let’s get one thing straight: coffee grounds are not just waste, they are a valuable resource for your garden. When used as a soil amendment, coffee grounds can provide your plants with essential nutrients that promote growth and overall health.

Coffee grounds are primarily composed of nitrogen, phosphorus, and potassium, which are commonly found in commercial fertilizers. However, unlike synthetic fertilizers that can harm beneficial microbes in the soil, coffee grounds nourish the soil without causing any harm.

Geraniums thrive in nutrient-rich soil that is well-draining and high in organic matter. By adding coffee grounds to the soil mix or simply sprinkling them around the plant roots, you not only enrich the soil but also improve its structure and water-holding capacity.

The result? Healthier geraniums that bloom more vibrantly than ever before.

Natural pest deterrent

If you’re tired of dealing with pesky insects like aphids and spider mites on your geraniums, listen up: coffee grounds can be a natural pest deterrent that saves you from using harmful pesticides. The secret lies in caffeine – yes, caffeine – which is present in high concentrations in coffee grounds.

When applied to the soil or plant leaves, caffeine acts as a toxin to insects by disrupting their nervous system and causing paralysis or death. The best part?

This natural pesticide only affects pests and has no negative impact on beneficial organisms like bees or butterflies. So what pests commonly infest geraniums that can be deterred by coffee grounds?

Aphids are one such pest known for damaging tender new growth on geraniums; spider mites cause yellowing leaves and webbing on plants; while mealybugs leave behind sticky honeydew residue that attracts ants. All of these nasty critters can be repelled by the caffeinated power of coffee grounds.

Composting with Coffee Grounds: The Ultimate Nutrient Boost

Composting with coffee grounds can be one of the best things you can do for your geraniums. Composting is a process that breaks down organic matter into nutrient-rich soil, which is then used to fertilize plants.

When you compost coffee grounds, you’re taking advantage of their high nitrogen content, which is essential for promoting healthy and robust plant growth. To start, you’ll want to gather a few things: a compost bin or pile, some leaves or other yard waste, and of course, your used coffee grounds.

Start by placing a layer of leaves in the bottom of your bin or pile. Next, add a layer of coffee grounds on top.

Repeat this process until all your coffee grounds are in the bin or pile. Now add another layer of leaves and mix everything together.

Over time, the microbes in the compost will break down the organic matter into nutrient-rich soil that’s perfect for geraniums! You can apply this soil directly around your plants as needed throughout the growing season.

Topical Application: A Quick Fix for Healthier Geraniums

If you don’t have time to wait for composting but still want to give your geraniums a boost with coffee grounds, a topical application might be right for you! By sprinkling coffee grounds directly onto the soil around your plants, you can provide them with an instant shot of nutrients. To apply coffee grounds topically:

1. Brew up some fresh coffee and let it cool. 2. Sprinkle the used coffee grounds around each plant.

3. Gently work them into the top inch or two of soil. 4. Water as normal.

It’s important not to overdo it when applying coffee grounds directly to geraniums. Too much can actually harm the plants, so stick to a thin layer of grounds no more than once or twice a month during the growing season.

Coffee Ground Myths Debunked

There are a lot of myths surrounding the use of coffee grounds on plants, and it’s time to set the record straight. One of the biggest myths is that coffee grounds will make your soil too acidic for plants to grow in.

This is simply not true. While coffee grounds are slightly acidic when they are fresh, they quickly neutralize as they decompose in the soil.

In fact, coffee grounds can actually help to buffer alkaline soils and bring them closer to a neutral pH. Another myth is that coffee grounds will attract pests like slugs and snails to your garden.

While it’s true that slugs and snails are attracted to caffeine, there isn’t enough caffeine in coffee grounds to be a significant attractant. In fact, as we mentioned earlier, coffee grounds can actually help to repel some pests due to their natural caffeine content.


Let’s talk about coffee for a minute. Coffee is one of the most popular beverages in the world, with billions of cups consumed every day. But what many people don’t realize is that coffee is also one of the most heavily sprayed crops on the planet.

In fact, conventional coffee farming uses more pesticides than any other crop except cotton. So what does this have to do with using coffee grounds on your geraniums?

Well, if you’re using conventional (non-organic) coffee beans, there’s a good chance that those beans have been sprayed with pesticides that could potentially harm your plants. That’s why it’s important to use organic or fair-trade coffee beans whenever possible.


Yes – coffee grounds are good for geraniums! They provide valuable nutrients for your plants and can even help deter pests naturally. But it’s important to use them correctly – either by composting them first or by applying them in a thin layer on top of your soil.

And remember to use organic or fair trade coffee beans to ensure the health of your plants and the planet. So next time you’re sipping on your favorite cup of coffee, don’t toss those grounds in the trash!

Give them a second life by using them in your garden. Your geraniums (and the environment) will thank you for it.
