This post will clear up the following question: do gardenias like coffee grounds? There are many articles and websites that say gardenias love coffee grounds, so it might seem a bit strange to hear this article says they don’t.

But is there any scientific evidence to back up either side of the argument? We have found some other plants that thrive with added compost or organic matter, but what about gardenias? Let’s find out

Do Gardenias Like Coffee Grounds?

Yes! Gardenias like coffee grounds because the grounds act as great mulch and provide the acidic soil that gardenias need to grow.

You see, coffee grounds are great for the soil because they release nitrogen into the earth and provide extra potassium.

However, this is not true with all plants in general, so it’s important to know if your plant likes coffee or even needs acidic soil before adding any ground-based mulch.

Although I’ve said, you may be surprised to hear that I don’t add coffee grounds to my own gardenias, or any plant for that matter. This is because uses a specialist fertilizer is a better option as it provides everything the plant needs to thrive, not just nitrogen.

What Are The Benefits of Adding Coffee Grounds to Gardenias?

Adding coffee grounds to plants has many benefits. This is because they are rich in nutrients like potassium, nitrogen, and phosphorous, which helps give the plant what it needs to thrive.

They also have anti-fungal properties that will discourage diseases from forming on your plants’ leaves or roots while improving their appearance over time as well. The compost helps keep weeds at bay too!

How Much Coffee Grounds To Use?

In order to get the best results for your gardenia, it’s important to know how many coffee grounds you should use.

You can apply around two handfuls of coffee grounds to the soil and water as normal.

You can also add coffee grounds to the soil around your gardenia when you are fertilizing it, or at least once every one and a half months.

What Happens If You Add Too Many Coffee Grounds?

If you add too many coffee grounds, it can lead to a buildup of nitrogen in the soil, which is not good for your gardenia plant. In addition, this may cause other issues, such as nutrient deficiencies or root rot if there are too many nutrients contained in the ground-based mulch.

So make sure that you don’t overdo it when adding any type of organic matter to your plants’ potting mix!

Conclusion

In conclusion, gardenias love coffee grounds because they provide the acidic soil that it needs to grow.

However, it is important to know that not all plants do and they may even be damaging. It’s best practice to read up on the plant you are growing before adding any extra fertilizers or mulch.

Although I recommend using coffee grounds on your gardenias if don’t want to throw coffee grounds away, I wouldn’t buy coffee grounds JUST to use as fertilizer. Instead, you an all-purpose fertilizer, like Miracle Grow.

If unsure, consult a local garden center as they’ll have plenty of advice for your specific type of plant.
