5 Benefits using Coffee Grounds for Peace Lilies

Sharing is caring!

Peace Lilies are considered to be evergreen tropical plants that thrive on forest grounds.

By replicating similar environmental conditions, Peace Lilies can thrive in an in-home environment and grow up to 16 inches (40cm) tall. Whereas those grown outdoors have leaves that are up to 6 feet in height (15cm). Peace Lilies thrive best in temperatures between 65 to 80 °F (18°C-26°C) and thrive by using a balanced fertilizer from time to time.

The big question here is if coffee grounds are good for Peace lily? Let’s find out.

 

Are Coffee Grounds Good for Peace Lilies?

Coffee grounds are popularly used as fertilizer due to their high nutrient content. Their acidic properties also make coffee grounds an excellent choice for reducing alkaline soil’s pH (soil pH of above 7). Additionally, they are also used in soil to ward off indoor pets and help in reversing the browning of Peace Lilies Leaves.

 

Benefits of Coffee Grounds for Peace Lilies

 

As a Fertilizer

Fertilizing indoor plants is an important step in plant care, especially in the case of plants like Peace Lilies.

Coffee Grounds make an excellent fertilizer for indoor plants as they are rich in nitrogen (2.5-3%). It is an essential nutrient if your Peace Lilies are to have green leaves and strong stems.

Peace Lilies, in general, do well with fertilizer mixtures containing nitrogen, phosphorous, and potassium.

Begin by adding coffee grounds to your soil once a month. You can always adjust the quantity in the future if there aren’t any improvements.

 

As pH balancer

Houseplants can be classified into two categories depending on their pH, either acidic or alkaline.

If your Peace Lilies are suffering due to high pH levels (alkaline soil), adding coffee ground can reduce the soil pH.

 

Using as Compost

Coffee grounds act as organic matter when added to the soil. This addition of coffee grounds helps improve the growth rate of your Peace Lilies by increasing water retention, providing aeration, and improving drainage.

 

Keeping Pets Away

Peace Lilies, although incredibly beautiful, are very toxic to indoor pets. The presence of calcium oxalate in its leaves and flowers make it poisonous.

If ingested, the reaction can manifest as respiratory and stomach irritation.

You can keep Peace Lilies out of reach of your pets to ensure their safety.

Furthermore, you can add coffee grounds to your soil as a fool-proof method of warding off your indoor pets.

 

Reversing Leaf Browning

Yellowing or browning on their leaf tips is quite common. The most probable cause of this is overwatering.

Coffee grounds improve drainage, thereby helping with overwatering. Although coffee grounds can reverse several types of leaf discoloration, it is recommended to overcome the root cause.

Your Peace Lilies could be undergoing discoloration due to excessive use of fertilizers, over-watering, improper drainage, wrong choice of fertilizer, and even under-watering your plants.

 

Others Benefits of Using Coffee Grounds

Coffee grounds can be used to promote vermicomposting. Earthworms use coffee grounds as a source of nutrition from the soil.

Promoting vermicomposting improves the soil aeration as they move about. Moreover, it is a great way of improving the nutrient content of the soil.

Additionally, coffee grounds can be used to discourage fungal infections and keep pests away.

Fusarium, Pythium, and Sclerotinia are few fungi species that coffee grounds can prevent from attacking your Peace Lilies.

On the other hand, snail and slugs that often infest soils can be kept away by sprinkling few coffee grounds onto the soil. The caffeine in the coffee grounds drives off these pets.

 

Problems Associated With the Use of Coffee Grounds for Peace Lilies

 

Attracts Pests

Although it’s previously mentioned that coffee grounds can ward off slugs and other pests, the reverse is true as well, coffee grounds can attract certain insects, like roaches. Hence, it’s recommended to use coffee grounds as compost rather than spreading them on the soil.

 

Stunts Growth

If your soil conditions are already acidic, further addition of coffee grounds will reduce the soil pH. Peace Lilies grow best in pH ranges of weak acids. Should the soil pH drop more than necessary, it will stunt the growth of your Peace Lilies.

 

Promotes Fungal Growth

Coffee grounds can provide an ideal environment for certain fungal diseases. These fungal diseases can lead to mold formation, which can harm your Peace Lilies. To prevent fungal growth, use your coffee grounds as compost rather than laying it on the soil.

 

Excessive Water Retention

The most common mistake faced by indoor plant owners is overwatering. Moreover, Coffee grounds are well-known to hold moisture.

When used as organic matter, the fine particles of coffee grounds act as a sponge. Hence using coffee grounds can significantly increase the risk of overwatering your Peace Lilies.

To overcome excessive water retention, you can alter the soil composition by adding perlite or coarse soil, using a smaller pot or pot that is porous.

These changes will improve drainage, reducing the risk of excessive water retention.

 

Other Better Alternatives to Using Coffee Grounds as Fertilizer for Peace Lilies

Grass clippings make an excellent fertilizer alternative to coffee grounds for Peace Lilies. They are rich in phosphorus, potassium, and nitrogen, all of which are essential to Peace Lilies.

Making your grass clipping fertilizer is fairly simple. Take your grass clippings and at them into a pot of water, following one to one ratio. Occasionally, stir the grass clipping-water mix over the course of three days.

However, note that natural fertilizers only last for two days. Hence, you will need to make a fresh batch regularly.

 

Frequently Asked Questions about Coffee Grounds and Peace Lilies

 

Can I use coffee directly on my Peace Lilies?

It is recommended you dilute your coffee grounds before you add them to the soil. Concentrated coffee can lead to fungal overgrowth and moisture retention.

 

In what pH do Peace Lilies thrive?

Peace Lilies grow best in acidic soil conditions, within the pH ranges of 5.8-6.5.
