Are Coffee Grounds Good for Succulents? (2024)

Many people throw their old coffee grounds into the compost pile and use it in their gardens with good results. But as you all know, what works best for other plants doesn’t always work for succulents, especially when it comes to fertilizer!

Chemical fertilizers more easily burn succulents than other plants, so there’s always a risk that your succulent babies could get damaged when you use them. Could coffee be a better alternative to harsh chemical fertilizers, or is it too acidic for your plants? One thing is for sure. It’s great to drink!

Today, we will tell you whether or not your succulents will love coffee as much as you do! By the end of this post, you’ll get all the info you need to decide if your coffee grounds should go in your succulent pot or in your garbage can, so read on!

Nutrients in Coffee

Coffee grounds are about 2% nitrogen, benefiting plant health and getting thrown into compost piles. Brewed coffee also has some pretty great nutrients – potassium and magnesium. Nitrogen, potassium, and magnesium are essential nutrients your plant babies need. If the soil you plant them in doesn’t have enough of these minerals, their leaves will start to turn pale, and they won’t be able to grow well. Yikes!

That’s why it’s so important to fertilize your succulents, especially if their home garden is an adorable little potor a rustic driftwood planter, which you can learn how to make by checking outour article down below. After living in that container, your succulents will use up all the available macronutrients in the soil, so you’ll have to add some nutrients to keep them healthy.

Coffee seems like a great way to do that because it has so many vital nutrients… but is it too acidic for your plants?

What Does Coffee Grounds Do For Soil? Is Coffee Good For Plants’ Soil?

OK, we know what you’re thinking… acid? How can that be good for my plants? But most plants, succulents included, grow best in slightly acidic conditions.

It all comes down to pH levels. The tap water you use to water your plants has a slightly alkaline pH of around 8, but plants grow best in slightly acidic soil. They like a pH between 5.8 and 7. So whenever you water your plants, you push the pH higher than they like!

So using something slightly acidic, like coffee, as fertilizer can help rebalance the pH and return it to the levels your plant baby prefers.

We’ve seen succulent growers online report good results from planting succulents in mildly acidic soil. Several people said their succulents looked healthier and bloomed more frequently. Those are just some of the benefits you can expect from fertilizing your succulents with coffee and paying attention to the pH levels of the soil!

Note: Use Diluted Coffee On Potted Succulents

Coffee grounds from your favorite coffee brand will work as fertilizer in your garden, but they won’t work on potted plants. Pots don’t have enough microbes hanging out in them to break down the coffee grounds into a form your succulent can use. If you brew the coffee grounds into coffee and dilute it with water, it will work well as an alternative to chemical fertilizer!

Brew a cup of your least favorite coffee—you wouldn’t want to waste the good stuff on your plants—and then dilute it with water. You should use equal amounts of coffee and water on your plants(Ratio of one to one). So if you brewed eight ounces of coffee, add eight ounces of tap water.

Now you can use that diluted coffee to water your plants like usual. Test out this DIY fertilizer a few times during your succulent’s active growing season to see if your plant baby likes it!

Are Coffee Grounds Good For Succulents?

Coffee grounds don’t work on potted plants, but if you have some succulents planted outside in your garden, you can place used coffee grounds directly onto the soil. As the used coffee grounds break down, they’ll add nitrogen to the soil, a vital succulent nutrient. They’ll also help aerate the soil, improve drainage, and even suppress weeds and keep pests away.

Remember not to add unbrewed coffee grounds to the soil—their high caffeine content can harm your plants! Brewed coffee grounds have much less caffeine, so they’re safe to use. We recommend any dark roast brews (or light roast brews that may have the same or a bit more caffeine) at the grocery store. The coffee from Maxwell House is a favorite of our office plants!
