Coffee Grounds for Plants

Coffee grounds are an excellent, natural fertilizer for houseplants. Not only do they add nutrients to the soil, but they can also increase the acidity of the soil, making it more suitable for acid-loving plants.

Those grounds are rich in nitrogen, potassium, and magnesium, which helps promote healthy green foliage and strong roots. But, before giving your plants a taste, make sure you dry the coffee grounds to reduce the risk of mold. You’ll also want to till the coffee grounds into the soil to prevent compaction.

So, without further ado, here are some examples of plants that love coffee grounds!

Philodendron is one of the most popular indoor plants in existence. This lovely indoor plant enjoys a slightly acidic soil and is easy to care for! Adding coffee grounds to your philodendron is a great way to give it an extra nutritional boost and slightly increase the acidity in the soil.

To get the most from your coffee grounds, apply them in moderation every four weeks during the growing season (spring and summer). Simply sprinkle a decent amount of dry, used coffee grounds around the base of your philodendron.

Christmas Cactus

This cheery plant loves a soil pH of  between 5.5 and 6.2, so used and dry grounds are an effective fertilizer for your cactus, helping to promote growth and maintain overall health.

Just spread a light layer over the surface of the soil in November to experience the benefits of this sustainable practice!

Jade plants are a favorite amongst succulent enthusiasts because of their unique foliage. And coffee grounds are great for fertilizing jade plants! You can apply them safely with minimal fuss.

To get the most out of this organic fertilizer, apply it every four weeks during the growing season (early spring to early fall).

Spread the coffee grounds evenly around the plant’s base, but be careful not to overload your jade plant with too much fertilizer; too much can cause root burn and other serious damage.

Cyclamen is a popular choice for winter flower displays because of its bright, cheery blooms. And adding coffee grounds to your cyclamen is a great way to give it the nourishment it needs for lush, vibrant flowers, as well as the slightly acidic soil it deserves.

Simply add a spoonful of the used coffee grounds every four to six weeks to your cyclamen’s soil or compost. These nutrients will help your cyclamen thrive, producing bright, abundant flowers throughout its growing season.

Coffee grounds can be a great supplement for your outdoor plants. The nitrogen and nutrient content of coffee grounds make them an ideal fertilizer. Simply sprinkle the grounds around the base of your plant, or even mix it into the soil.

However, when using coffee grounds on indoor plants, exercise caution. Because they are so finely ground, they can pack down tightly in soil and reduce aeration. This can lead to fungal growth and a buildup of soluble salts that might damage your plants.

Fruit flies are also attracted to damp coffee grounds, which could become a problem. You may still want to use coffee grounds for your indoor plants, but take proper precautionary measures!

Share Your Morning Cup of Coffee

Used coffee grounds are a fantastic way to give your plants the nutrients they need. And you can feel good knowing that you’re using every last bit of your favorite drink. So, next time you brew a pot of coffee, save some grounds for your greenery. Your plant babies will thank you!
