Is Coffee Grounds Beneficial for Plants?

“Plants are just like us; in addition to water and sunlight, they need nutrients to grow. The difference from us is that plants get their nutrients from the soil. Many people put coffee grounds in the soil so that the plants grow better. It is believed that this way the plant will get better nutrients. is it really true? “

Although coffee grounds contain small amounts of nitrogen, it is not a type of fertilizer. It turns out that nitrogen, a nutrient essential for the growth of plants, was not present in the grounds immediately after brewing. To provide any real value to the plants, coffee grounds need some time to break down in a compost pile.

Organic matter must first be decomposed (by composting) in order to obtain the individual nutrients in plants. Soil researchers at the University of Melbourne applied coffee grounds directly to broccoli, leek, radish, viola, and sunflower soil. Coffee grounds seemed to increase the amount of water the soil could hold, but eventually prevented the growth of all five types of plants.

Uncomposed kitchen scraps of all kinds can attract unwanted fungi, bacteria and fungal mosquitoes into your plant, as well as creating the conditions for mold.

How is coffee grounds used for plants?

1.Add the grounds to your compost pile

In addition to nitrogen, coffee grounds can add phosphorus and potassium to your finished compost, both of which help the plant grow. Add the coffee grounds to your compost bin, and if you’re lucky, you’ll have a nutrient-dense soil additive after a few months.

2. Make a compost tea

If you prefer to use liquid feed instead of adding the finished compost to your potting mix, you can brew your own compost tea. Compost tea will also contain soluble nutrients from compost and some beneficial microbes.
