Using coffee grounds to fertilize plants is very good but must be used properly
1. Detailed analysis of nutritional ingredients in coffee grounds
Used coffee grounds, especially the composted variety, are an excellent source of organic nutrients for plants. The average nutritional composition of coffee grounds includes:
- Nitrogen (Protein – N): About 2% (Organic Protein). Nitrogen is a key factor that helps plants develop leaves and stems. Although coffee grounds contain protein, this protein is slowly released when microorganisms decompose organic matter, helping plants absorb it more sustainably than with chemical fertilizers.
- Phosphorus (Phosphorus – P): About 0.2% – 0.4%. Helps plant roots grow strongly, enhancing flowering and fruiting.
- Potassium (Potassium – K): About 0.6% – 0.8%. Important for overall plant health, helps increase disease resistance and agricultural product quality (sweeter, better color).
- Microminerals: Contains Magnesium (Mg), Calcium (Ca), Copper (Cu), Iron (Fe), Zinc (Zn) in significant amounts, supplementing trace elements that soil is often lacking.
- Organic matter: Accounts for 75% – 85%. Helps improve soil structure, increase porosity and water holding capacity, creating an ideal environment for roots and soil microorganisms to grow.
With a N:P:K ratio of about 2:0.3:0.7, coffee grounds are an organic fertilizer that is rich in nitrogen and potassium, very suitable for the stage of plant growth and preparation for flowering.
2. Why are coffee grounds used in plant fertilizer?
Coffee grounds are agricultural products that are removed during the annual coffee processing process.This residuepossesses a lot of nutritional ingredients. These nutrients have very good effects for farming activities.
There are coffee grounds in thereapprox80% is organic matter and minerals. That’s why,residueCoffee can be used to process into organic fertilizer. This type of fertilizer not only brings high efficiency in growing plants but also helps save costs. So, the number of people choosingCoffee grounds fertilize plantsincreasingly increasing.
Coffee grounds contain many useful nutrients for plants such as nitrogen, phosphorus, magnesium, potassium, organic matter, soil-sponging fiber… Therefore, it is used as fertilizer for plants, helping to accelerate the growth process of plants and effectively improve the soil. In particular, coffee grounds are very suitable for use as fertilizer for plants that prefer mildly acidic soil environments such as sweet potatoes, potatoes, roses, carrots, cabbage, onions, etc.
Besides, the continuous cultivation process along with the excessive use of organic fertilizers and pesticides has caused the land to become infertile and poor in nutrients. Organic fertilizer made from coffee grounds is an effective solution to improve soil.
Organic fertilizer from coffee grounds will provide nutrients to the soil, increasing humus and fertility. Beneficial microorganisms will work strongly to create a pH balance in the soil. Make sure the soil becomes more fertile and loose.
ButtoCoffee grounds applied to plants need to be composted before use. Avoid applying pure coffee grounds to create an environment for fungal diseases to growBecause fresh coffee grounds may contain growth inhibitors and have high decomposition temperatures that are harmful to roots.
Coffee grounds have many nutrients that are good for plants
3. Common applications of composted coffee grounds
Coffee grounds fertilize plantsused more and more commonly. People can take advantage of coffee grounds to make fertilizer, create an environment for earthworms to live in, improve soil, grow mushrooms, roses, etc. With each application, coffee grounds will bring different effects. Specifically:
3.1 Use coffee grounds as fertilizer
People can take advantage of coffee grounds mixed with other organic products to make fertilizer. These types of organic matter are composted with microbial products to become nutrient-rich organic fertilizer.
However, to be highly effective, the amount of coffee grounds used should be at a reasonable level. Accordingly, coffee grounds should not exceed 25%.total volume of composted materials. The composted coffee grounds will provide minerals, moisture, potassium, magnesium, and protein. This helps organic fertilizer add humus and does not become too dry, affecting quality.
When plants are fertilized with organic fertilizer from coffee grounds, they will have new sources of nutrients, stimulating rapid growth. People can mix coffee grounds with seeds before planting or fertilizing other plants such as green vegetables, roses, cabbage, etc.

3.2 Coffee grounds are used to feed earthworms
Earthworm is a very nutritious animal. They are effective in loosening soil, preparing food for animals, etc. People can use coffee grounds in raising earthworms or earthworms. Coffee grounds create a well-ventilated environment and retain moisture well. Create ideal living conditions, helping earthworms grow quickly.
3.3 Coffee grounds repel ants and pathogens that harm plants
Coffee grounds fertilize plantsIt is also effective in repelling ants and harmful pathogens. Ingredients in coffee grounds contain nitrogenorganic. When sprinkled directly (thin layer) or used as irrigation solution on the soil, coffee grounds are said to have the ability to create an unfavorable environment.for ants and some typesslug/snaildevelop. When coffee grounds are spread all over fruit trees, roses, etc., ants will not be able to crawl up the trees and harm the flowers and fruits.
In addition, coffee grounds can also help plants prevent pest attacks. Protect farmers from having a bumper crop without using toxic pesticides.
3.4 Coffee grounds are effective in improving soil
One of the great effects of coffee grounds is the ability to improve soil. Soil after a long period of cultivation is easily poor in nutrients. Fertilizing composted coffee grounds will be an effective solution to add nutrients to the soil.
The soil will be supplemented with an additional source of nutrients and beneficial microorganisms. Besides, coffee grounds also have the ability to retain moisture well. Therefore, the soil will become more porous and fertile. Becomes an ideal growing environment for plants in the next season.
In addition, with organic fertilizer from coffee grounds, even if applied in large amounts, the soil will not experience poisoning like chemical fertilizers. The nutrients will be dissolved by the soil and gradually absorbed by the plants over a safe long period of time.
Coffee grounds improve soil very effectively
3.5 Use coffee grounds to grow mushrooms
Coffee grounds can be used to grow mushrooms. Coffee grounds meet the criteria of nutrition, air permeability and good moisture retention for mushroom growing media. Mushrooms can grow well from a substrate made from coffee grounds. Mushroom growers can save a large amount of money.
4. How to compost coffee grounds to fertilize plants effectively
To be able to useCoffee grounds fertilize plantsneed to go through the composting process. Organic fertilizer from coffee grounds will help plants grow quickly and yield high yields. Besides, the soil will also be supplemented with a large amount of nutrients. The process of composting coffee grounds will be done with the following ingredients and processes:
4.1 Ingredients needed to prepare to brew coffee grounds
Ingredients people need to prepare for brewing coffee grounds will include:
- Coffee groundsfresh (or pre-dried)was crushed and incubated for about 5 days before being composted. You should combine a large quantity of coffee grounds to ensure that each brew takes less time.
- Manure (preliminarily treated)
- Composting product EMZEO+ Trichoderma bacillus fungusDuc Binh
- Composting molasses
- Phosphate fertilizer, urea fertilizer(optional to adjust C/N ratio and promote incubation)
- Clean water
Besides the ingredients, people also need to prepare some additional supporting tools such as shovels, tarpaulins, rakes, etc.
4.2 Select a location to compost coffee and process raw materials
To proceed with incubationCoffee grounds fertilize plants, you need to choose a suitable incubation location. You should choose a spacious, well-ventilated area to ensure the incubation process goes smoothly and is easy to use. Do not compost coffee grounds in flooded locations to avoid rain. You should cover the bottom with a layer of tarpaulin to avoid water infiltration.
Once you have a suitable location, you need to proceed with processing the materials. Water the coffee grounds to moisten them. Mixresiduecoffee, manure, lime, urea, and phosphate fertilizer evenly. Each layer of coffee grounds will be mixed with a thin layer of phosphate and urea fertilizer(if used).
4.3 Mixing microbial products
Take Trichoderma mushroom and EMZEO product and mix it with clean water to create a yeast mixture. Add molasses to create a coffee grounds brew solution. The ratio of biological products used to mix with water needs to be consistent with the amount of coffee grounds used.
Every layer of mixtureCoffee grounds fertilize plantswill be watered with a layer of probiotic solution. The process is repeated until all the coffee grounds that need to be brewed are gone. Then use a rake to mix all the ingredients together. You can determine the appropriate humidity by holding the mixture tightly in your hand and seeing the water leak through your fingers(ideal humidity is about 50% – 60%).
Mix the ingredients into a large pile and cover with tarpaulin to cover. Covering will prevent flies from coming into contact with the compost. Besides, it keeps air and moisture tight for coffee grounds.
Mix ingredients well to brew coffee grounds
4.4 Add more water and biological products
After about 7 days of incubation, you need to open the canvas to check the condition of the coffee grounds. If the outer layer of the compost pile turns black and the temperature is about 60 degrees, you can continue to cover and compost.
In case the compost pile has not yet changed color, you can add clean water and biological products. You should water evenly to ensure appropriate humidity. Next, cover the canvas as before.It is also important to turn the compost pile every 7-10 days to provide oxygen and ensure even decomposition.
Use a discreet cover
4.5 Finished product inspection
After about 20 days, you will have to check the pile again. The surface of the compost pile will have white layers of microorganisms(it could be mushroomsTrichodermaor actinomycetes).If the compost pile is dry, you can continue to add water to ensure moisture in the coffee grounds.
Coffee grounds will turn into a completely decomposed state after about 4-5 months(if not using biological products). If biological products are used, the incubation time can be shortened to about 45−60 days depending on environmental conditions.Successfully brewed coffee grounds will be humus-like, dry and will not have a bad odor. Everyone can use it to fertilize plants. Depending on the type of plant, use the appropriate dose of coffee grounds. Excess coffee grounds can be stored in a plastic-lined bagor sacks in a dry place.
Check the finished product after incubation
