What is compost fertilizer? Compost manure is the substance that is produced in the organic system as a result of the action of various microorganisms from plant and animal wastes. In addition to nitrogen and carbon, the benefits of this fertilizer are incomparable to root, leaf, flower, and fruit for curry leaf plants. The application of compost manure is as great as the growth of curry leaf plants. That is why the people involved in curry leaf cultivation have lovingly named it the black gold of the curry leaf plant.

Benefits of compost fertilizer

Good organic manure compost. Applying this fertilizer in the garden or in the tub enriches the soil and increases the fertility of the soil. This fertilizer greatly enhances the water holding capacity of the soil. There are also many other benefits of compost. This fertilizer:

  • Increases ventilation in the core of the soil.
  • Increases the activity of beneficial microorganisms in the soil.
  • Helps to control soil acidity.
  • Helps prevent erosion. And also
  • When applied on the ground, it works as mulching or covering.

How to make homemade compost fertilizer for curry leaf plant

Place for making compost manure

You can make compost by digging a shallow hole in one corner of the garden and storing the organic waste in the house. However, using the compost bin can be to your advantage. Different models of compost bins made of metal or plastic are available in the market. You can make your own wooden or plastic compost bin to store organic waste. Whether the bin is purchased or self-made, you need to make sure that it has enough holes or ventilation around it for ventilation.

Ingredients for making compost manure

What can be used in composting?

Holes or bins, wherever you do composting, you need to know in advance what kind of waste can be used in the method of making compost and what kind of waste cannot be used. The method of making compost manure is an organic method. The main ingredients are mainly divided into two parts, green and brown. Examples of greens: vegetable peels, fruit peels, garden green grasses, weeds, etc. The brown group includes: dried leaves and small stalks of trees, pieces of paper, pieces of cardboard, straw, dried tea leaves, etc. In addition to green and brown, another type of material can be added to the composting process. That is white, that is, the eggshell.

The green ingredients for making compost are high in nitrogen. The brown ingredients provide extra carbon for fertilizer. Another benefit of brown ingredients is that they also help to remove odors during composting. The white material comes from the shell of the egg and it adds a lot of calcium to the compost manure. In the process of making compost manure, it is better to mix the green and brown ingredients in the ratio of 2:1 according to the weight. However, even if this ratio is a little more or less, there are no major problems in composting.

What cannot be used in composting

It is better not to use fish skewers, bones of fish, pieces of fish or meat, liquid part of eggs, milk products, or any other animal remains in the method of making compost manure at home. These can spread rotten odor. Moreover, there is a fear of spreading diseases from these. For the same reason, it is not right to use the waste of dogs, cats, or any other carnivorous animal to make compost manure. However, there is no problem in adding various vegetarian animals, such as cow, goat or sheep waste to the composting mixture. This will improve the quality of the fertilizer produced.

Any vegetable or animal residue containing pesticides or any other pesticides should not be used in composting. Care should also be taken to ensure that plastic or any ‘non-biodegradable waste, which does not mix easily with the environment, does not get into the composting mixture.


The composting process requires occasional mixing of organic matter with moderate water. This should be done in such a way that the compost manure waste always has a wet feel to it, but it cannot be given too much water.

The wind

In case of domestic composting, the composting mixture must be adequately ventilated. For this, when making compost in the hole, at least once a week, the hole mixture should be shoveled with a spade or shovel. If you use a compost bin, you have to shake the compost bin well in a couple of days. During composting, if air reaches all parts of the composting mixture properly, it will not give off a bad smell. The quality of the fertilizer produced will also be good. This method of making compost manure is known as the aerobic method.


Organic waste can sometimes be added to small amounts of garden soil to make compost manure. The advantage of this is that it will speed up the composting process. Also, if you ever feel the smell coming from a composting mixture, cover the mixture with some brown material, such as a piece of paper, a piece of cardboard, straw or dried leaves. This will stop the spread of odor.

Things to keep in mind

The organic waste mixture of the house should not be given to the curry leaf plant till it is completely decomposed. If the organic waste mixture is applied to the leaves of the curry plant before it turns into rotted manure, the plant may die. It may take at least three/four months for compost to be made from the organic waste mixture. This can take up to a year also. It remains to be seen whether the composting mixture is ready for use as a fertilizer. When fertilized, the color will be dark or dark brown, the structure will be loosely or crumbly and the smell will be just like soil.

One more urgent thing at the end of it all. Nothing is too good. The same is true of homemade black gold compost manure in the garden. The plants should be given as much compost as they need. With moderate compost fertilizer application, the curry plants in your garden or tub will be leafy, bloom, and become beautiful. There will be no need to give extra fertilizer.

Used tea bags/tea leaves

Fresh or used tea leaves contain tannic acid (tannin), which when added to the soil increases nitrogen levels in the soil and creates a fertile environment for plants. Nitrogen is a necessary component for plant enlargement and improvement. Although nitrogen is one of the greatest rich items in the world, nitrogen shortage is most likely the usual dilemma affecting plants worldwide. Nitrogen is not found straightly in plants from the environment and the land’s crust. Most importantly, nitrogen deficiency in plants disrupts chlorophyll production and hinders plant food production. Adding nitrogen to the soil through organic fertilizers is also safer for the environment than chemical fertilizers.

Due to the presence of natural organic matter in the tea leaves, it increases the level of nutrients required by the plants and at the same time enhances the quality of the soil. This attracts earthworms and other beneficial microorganisms and increases their activity.

Proper rules of use

After using the tea bag or tea leaves, wash them thoroughly in cold water and separate them from other ingredients (ginger, cardamom, cinnamon, bay leaves, etc.). Then dry it in the sun one day and store it. You can also use this dried tea leaf at the base of the curry leaves plant or mix it with tea leaves, dried eggshell powder, and banana peel powder in equal proportions and use it once a month. Before flowering on the curry plant, you can mix a mixture of tea leaves, dried eggshell powder, and banana peel in the ratio of 2: 1: 2 and use it at the base of the plant. Before applying these to the soil, loosen the soil as required and water the roots of the plant after mixing the fertilizer.


Homemade eggshell fertilizer

Eggshells are made up of more than 95% minerals. Eggshells contain mainly calcium carbonate (37%), which is essential for plant growth. In the absence of calcium, the young tips develop poorly and their number decreases with time. In the absence of calcium, the edges of the curry leaves appear dead and scorched, the roots weaken and the plants fall. Thus, eggshells help in increasing the calcium of curry plants. Eggshells also contain a lot of phosphorus. Phosphorus greatly affects the fruit and flowers of the curry leaf plant. Phosphorus is essential for the growth of curry leaf roots and stems. This is very important for pollination and seed germination. Phosphorus helps plants to produce lots of flowers and fruits. Eggshells also contain magnesium, potassium, and iron.

Proper rules of use

After keeping the eggshells for a few days, they should be washed well and dried in the sun. Then they can be crushed and stored for several days. Then it will be possible to use them as needed by the plant.

Banana peels

Banana peels contain about 42% potassium. Potassium has a direct effect on plant growth. Increases the immunity of plants to fight against harmful insects. Helps in fruit development. It controls about 50 different enzymes in plants. 

Potassium protects plants when the weather is cold or dry. In addition to potassium, banana peel is also rich in calcium and manganese.It accelerates germination, healthy roots, flowering, pollen formation, and fruit formation.

Proper rules of use

  1. Soak the banana peel in water for one or two days. Then use that water at the base of your plants.
  2. If you want to use all the parts of the banana peel, cut the banana peels. Dry the cut pieces in the oven or in the sun. Then use them at the base of the plant. This will increase the water-holding capacity of the soil along with the required elements.
  3. You can also mix banana peel directly in the soil. For this, cut the banana peels very short. The cut shells are buried 4 inches deep in the soil. Do this before planting. The shells will rot and mix with the soil. The vitamins and minerals in the banana peels will increase soil fertility. The curry plants in your garden will also become fresh by getting nutrition from the fertile soil.
  4. Many times flies or such insects are a nuisance in the garden. You can make an insect trap to get rid of it. This method is also not toxic. Take some pieces of banana peel, grate it and mix with apple cider vinegar. Fill a jar with this mixture and shake well. When the smell of banana starts to come out, make a hole in the jar. Leave it in the garden. Then your insects will be trapped and your garden will be free from harmful insects.
  5. The use of fermented banana peels in the garden will increase the productivity of the curry plant. You can use banana peel in this way to get the flowers and leaves of the curry plant. Put the banana peel in a jar. Put water in it. The banana peel should be submerged in water. Cover the mouth of the jar with a cloth and tie it with a rubber band. Leave it for a week. If you see the presence of algae, throw it away. If the banana peel is fermented, you will notice the smell. Remove it from the water and mix it with the soil. You can also spread the excess water at the base of the curry plant in the garden.

Wood ash – natural fertilizer

Wood ash is good potash and phosphorus fertilizer for acid or neutral soils. In addition to potassium and phosphorus, wood ash contains calcium, magnesium, iron, sulfur, zinc, and many other trace elements. It is enough to add 1-2 tablespoons of wood ash per square meter when planting seedlings and while digging the beds. Sprinkle the ashes very early in the morning after dew or spraying with clean water.

Onion peel

Use it to make potassium-rich fertilizers for almost all types of plants. The use of onion peels will increase the immunity of the curry plant, strengthen the stems and increase productivity. Fertilizers made from onion peel are rich in calcium, iron, magnesium, and copper.

Proper rules of use

Soak 2-3 handfuls of onion peel in 1 liter of water for 24 hours. If the water is colored and thick, separate the water from the peel. Use this water fertilizer on plants 3-4 times a month.

Orange peel

Orange peel contains a chemical called D-limonene which can be used as a natural pesticide. It damages the nervous system of insects like aphids, ants and kills them. You can directly put orange peel or spray around the plants that have insect problems.

Proper rules of use

Boil a few orange peels in water for ten minutes. When cold, separate the water into a spray bottle and spray your plants once a week.

Epsom salt

Epsom salt will help reduce magnesium and sulfur deficiencies. Mix one tablespoon of Epsom salt in one gallon of water. Spread on plant leaves with a sprayer. Once a month you will get good results.

Kitchen scraps

Do not peel vegetables after cutting them in the kitchen. You can collect them and give them to the plant. Maybe carrot or banana peel. Everyone is instructed to keep the vegetable peels in water for a week. Then you have to pour the water at the base of the tree. This will help a lot even if your plant gets nutrition slowly. It will also help to retain soil moisture during the hot season.

Sour yogurt and buttermilk mixture

A mixture of sour yogurt and buttermilk is a homemade fertilizer very useful for curry leaf plants. This mixture provides the nitrogen needed for curry plants. As well as this it creates a good habitat for the beneficial microorganisms present in the soil. This mixture provides nitrogen as well as other nutrients such as calcium, potassium, and phosphorus which makes the curry leaves alive and vibrant. The best time to apply this sour yogurt and buttermilk mixture is when the soil is dry. In winter, when the curry plants are in a dormant condition, their water demand is less, in which case this mixture can be given on dry soil and on the surface of the plant. Buttermilk makes the soil acidic and sour yogurt contains a variety of organic ingredients and probiotics that create high microbe levels in the plant-soil that help fight diseases against bacteria, fungi, black spots, white spots, powdery mildew, etc. It increases the immunity system of the plant.

How to apply the mixture of buttermilk and sour yogurt on the leaves of the curry plant?

  • The soil of the plant should be completely dried before applying the mixture.
  • Mix 2 tablespoons of sour yogurt and buttermilk in 1 gallon of water and mix well with water.
  • The mixture should be applied at the base of the tree once a week.
  • Rice washing water can be used instead of plain water to get good results.

Rice washing water

Rice washing water is the most readily available ingredient in home remedies for curry leaves. Vitamin B, starch, and other trace micronutrients including nitrogen, phosphorus, potassium are available in rice washing water which helps in plant root growth. It acts as a stimulant in creating new roots for curry plants.

The application process of rice washing water to curry leaf plant

  • Store water after washing white or brown rice.
  • When irrigating the plants, you can use rice washing water instead of plain water.
  • For better results you can add a mixture of sour yogurt and buttermilk with rice washing water.

Aquarium water

If you have a fish aquarium at home, save aquarium water before cleaning the aquarium every time. Aquarium water is a good source of nitrogen and phosphorus. We can use the water from this aquarium at the base of the curry plant. We can also use fish wash water at the base of curry plants. However, before using aquarium water or fish washing water on the plant, it is necessary to bring the plant outside the house and apply it, otherwise a bad smell will spread in the house.

Cow dung

Dung manure is the manure that is made by mixing and decomposing cow dung together. This fertilizer is a very well-known and high-quality fertilizer to the farmers of the country. Such a large amount of organic manure is not found in any other domestic animal. But due to lack of proper storage, a large part of this valuable fertilizer is lost.

How to make cow dung in an improved way?

  • Make a hole 1.5 m wide, 3 m long and 1 m deep by choosing a slightly higher place near the barn. You can make small, big or multiple holes by knowing the amount of dung.
  • Beat the bottom of the hole well and spread straw, gravel, sand on it so that it can easily absorb water or cover the bottom of the hole well with dung. The bottom of the hole should be slightly sloping towards the bottom and the top of the hole should be elevated with isles around it so that rain water cannot enter the hole.
  • It is better to fill the hole by dropping dung from the side of the hole or to fill the hole one by one in a few days by dividing the hole into several parts.
  • Pour the fine soil from the bottom of the pond or sinkhole in the gaps between the manure and the pit, as this makes the layer tight and there is no possibility of the manure evaporating.
  • After about a month and a half, the pile of fertilizer has to be turned upside down. If the pile is dry, soak it with fresh cow dung and urine because cow urine is also an excellent fertilizer.
  • The quality of organic manure is better when using TSP with dung. You can use 15 to 20 kg TSP per ton of dung.
  • In order to prevent the dung from drying out in the hot sun and from being washed away in the rain, put a shed on top of the pile. You can make this shed at low cost with straw, date leaves or palm leaves.
  • Thus, within 2-3 months of storage, good quality manure is made by decomposing the dung which is suitable for later use in the land. Reduce dependence on chemical fertilizers by using organic fertilizers and try to save the environment.

Quick compost manure

It takes 2 to 3 months to make ordinary compost manure. At the farmer level, it is always difficult to prepare ordinary compost manure. Therefore, quick compost manure can be made in a very short time and in an easy way. Quick compost manure can be made in just 14-15 days. It increases the water-holding capacity of the soil. Makes plant nutrients readily available. Increases the activity of soil microorganisms. Helps in the growth of plant roots and limbs. Works as mulching in vegetable crops. Above all, it protects soil fertility and increases crop productivity.

Ingredients and proportions required for making quick compost: Rotten cow dung, wood powder, and khail. The ratio of the mixture of ingredients will be Rotten cow dung: Wood Powder: Khail = 4: 2: 1.

Quick compost preparation method

Mix 1 part khail well with 2 parts wood powder or rice husk and 4 parts rotten dung or chicken manure. A moderate amount of water should be mixed in such a way that all the ingredients are mixed very well. The ingredients are mixed well to form a kind of yeast. This is how balls can be made with the yeast of that mixture. If the ball is released from the waist or 1 meter above, then if the ball does not break at all, then it must be understood that the amount of water is correct. The mixture should then be piled up so that water vapor is trapped inside to facilitate digestion. It is better to weigh 300 to 400 kg.

In winter, the pile should be covered with burlap sacks. From 24 hours after the pile, the temperature inside the mixture continues to rise and within 48-72 hours, the temperature of the pile is 600-700° C. If that amount of temperature is felt, the pile should be broken and the mixture should be inverted and the mixture should be cooled for 1 hour and kept in the pile again. If too much heat is felt in the pile, the same amount of rotten dung or poultry manure should be mixed again. This pile will smell like ammonia. The pile should be turned upside down every 2-3 days. The process will continue. It is useful to apply the mixed organic manure in the soil within 14-18 days. One of the main signs of quick compost manure being useful is that there will be no heat or odor at this time and it will turn black and brown, dry and crumbly.


The mixture should be placed in a high and shady place. A polythene sheet should be placed under the pile so that the required nutrients in the mixture do not go to the soil.


Quick compost contains 2.56% nitrogen, 0.98% phosphorus and 0.75% potassium per 100 kg. Moreover, moderate amounts of calcium, magnesium and other secondary nutrients are available.

Preservation: Quick compost should be dried in the shade in such a way that no juice can be seen in it when pressed with the palm of the hand. In this way, it can be stored in jute bags or earthenware for future use.

Earthworm manure

The worms make fertilizer for the land by eating the discarded parts of vegetables, fruit peels, plant herbs, animal intestines, poultry droppings, and chopped straw. This fertilizer can be used in all types of plants.


Vermicompost fertilizer contains 10 of the 16 essential nutrients of the plant. The study found that the standard vermicompost contains organic matter 28.32%, nitrogen 1.57%, phosphorus 1.26%, potassium 2.60%, calcium %, magnesium 0.66%, sulfur 0.74%, boron 0. 06%, iron 975 ppm, manganese 712 ppm, zinc 400 ppm, and copper 20 ppm.

Importance of earthworm

The digestive material that is excreted in the feces after the earthworm meal is called a cast. Increasing the number of germs inside the cast and its activity increases the fertility of the soil. It has been found that the number of germs in the cast is about a thousand times higher than in the surrounding soil. Soil fertility is also increased due to the presence of various enzyme-producing bacteria on the cast. The cast has been found to add 6% nitrogen and 15-30% phosphorus to the plants from the soil. Also, other plant food elements like calcium, magnesium plants can take more amount. In the presence of earthworms, the carbon and nitrogen ratio of organic matter is around 20: 1. In this ratio, the plant can easily take food from compost.

Earthworm manure cultivation method

Mix at least 60% dung with all types of organic waste of the house such as banana peel, water hyacinth, tree leaves, weeds, etc. and cut it into small pieces and fill it in a polythene bag and keep it in a shady place for 10-12 days. Build a house with brick sand 5 feet by 6 feet high in a shady high place. Pour the dung-mixed garbage inside the house and release about 500 earthworms. Cover it with some coconut leaves on top. In the dry season, sprinkle one to three kg of water every six to seven days if necessary. If cared for in this condition, the earthworms will eat the garbage and turn it into earthworm manure. Manure and earthworm should be separated by removing the manure from the house and sifting it through a perforated sieve of 0.5 cm or one-fifth of 1 inch. Manures can be used for crops and plants and earthworms can be used for making new fertilizers. Apart from this, it is possible to produce earthworm manure by pot method, enclosure method.


Ants, termites, cockroaches, beetles, chickens, and various birds are the enemies of earthworms. These will not die with any pesticide. However, pesticides can be given around the house. Ash, sand, broken glass, etc. cannot be kept with used dung. Keep the house covered with a lid to protect it from chicken and bird attacks. To keep the earthworms alive and active, the house should not be watered too much, nor should the water be drained. If there is any other species of earthworm in the house other than the specified species while sifting, it can no longer be used for making fertilizer.

Caution to use homemade fertilizer for curry leaf plant

  • Never apply more fertilizer to plants below one year of age.
  • Always use balanced fertilizer for best results. It is a good idea to use granular and liquid fertilizer with homemade fertilizer for best results.
  • With the onset of winter, the plants need less water and fertilizer, limiting watering and fertilization in winter.
  • Curry leaf growth is hampered in winter due to variations in weather and low temperatures. Ensure adequate sunlight at this time. And move the curry leaves indoors during the winter.
  • When mixing granular fertilizer in the soil at the base of the plant, take care not to damage the roots of the plant. If the roots of the plant are damaged, the growth of the plant is disrupted and in many cases the plant may die.
  • Fish emulsion fertilizer should be applied to the leaves of the plant after it is taken out of the plant from the house. Otherwise it can spread a bad smell in the house.
  • Seaweed fertilizer should be applied to the plant every three consecutive weeks. A mixture of sour yogurt and buttermilk with seaweed fertilizer can be used.
  • In cold and cloudy weather, apply fertilizers and pesticides on the leaves. Keep the plant away from scorching sunlight after applying fertilizers and pesticides. Otherwise it can burn the leaves of the plant.
  • Water the plant regularly. Stop watering the plant before applying the fertilizer. This will allow the thirsty plant to fully absorb nutrients and fertilizers when it regains water.
  • After using aquarium water and fish emulsion fertilizer, enclose the plant with a fence. Otherwise, pets may be attracted to the smell of fish and dig the soil and destroy the plants.
  • If flies, scales, aphids, ants and other insects are attacked by applying fertilizer on the leaves of the plant, apply neem oil or wood ash on the leaves.

Frequently asked questions

How do you fertilize curry leaves?

Compost manure should be mixed with the soil before planting curry plant seedlings. Tea leaves, dried eggshell powder, and banana peel should be applied at the base of the plant in the ratio of 2: 1: 2. Wood ash 1-2 tablespoons per square meter should be given to the soil at the time of planting seedlings. 1 tablespoon of Epsom salt in 1 gallon of water should be sprayed on the leaves of the plant. Mix 2 tablespoons of sour yogurt and buttermilk in 1 gallon of water and use it once a week at the base of the plant. Cow dung, earthworm should be applied to medium to large-sized curry plants 3 to 4 kg.

Half a teaspoon of Asafoetida powder mixed with buttermilk or sour yogurt water should be used once a week at the base of the plant. 2 tablespoons of fish emulsion mixed with 1 gallon of water should be used once a week on the leaves and roots.

How can I increase my curry leaves?

Urea is a nitrogen-containing chemical fertilizer that helps plant leaves grow. Regular use of compost manure, blood meal, asafoetida powder, fish emulsion, seaweed fertilizer at the base, and leaves of the plant makes the leaves green and increases in number.

In addition to fertilizer application, the plant needs regular watering, pruning, adequate sunlight, ventilation, and winter care, so that more leaves can be found on the curry plants.

Is buttermilk good for curry leaf plant?

A mixture of buttermilk and sour yogurt is a very useful homemade fertilizer for curry leaf plants. When it is used regularly with rice washing water, the leaves of the curry plant become green, bright, and grow in size.

Can we use Epsom salt for curry leaf plant?

Epsom salts are a great source of magnesium. Many people ask if the curry plant leaves are turning yellow, what should I do? In that case, 2 tablespoons of Epsom salt mixed with 1 gallon of water and applied to the leaves of curry plants will turn the yellow leaves green.

Last words

We discussed above in detail what fertilizers can be made from homemade ingredients for curry plants and how to make them. Doubts may arise as to whether fertilizers made from such well-known ingredients will actually work. But know that homemade fertilizers are much richer in nutrients than chemical fertilizers. Black Gold Compost for Garden, Tea Leaf Fertilizer, Egg Shell, Crushed Banana Peel, Onion Peel, Orange Peel, Epsom Salt, Mixture of Sour Yogurt-Buttermilk, Rice Washing Water, Aquarium Water, Cow Dung, Quick Compost, Earthworm Fertilizer, etc. the number of nutrients that home-made will be able to give to your plant will not be able to give the same amount of nutritional value as the chemical fertilizer bought in the market. So be sure to use homemade fertilizers rich in natural ingredients for your curry instead of chemical fertilizers. Feel free to use homemade fertilizer for curry leaf plants rich in natural ingredients instead of chemical fertilizers.
