Experienced gardeners often recommend using banana peels as fertilizer and using them both separately and as a potassium component for seedlings of crops and flowers. There are several simple recipes for making fertilizer based on banana skins, each of which has been tested over years of growing plants. What many consider to be garbage and throw in a bin, helps seedlings to grow like pies by leaps and bounds, because... The peel of the exotic delicacy contains all the substances important for plant development. By fertilizing seedlings with banana shells, you can significantly increase the quality and quantity of flowers and yield.
Chemical composition of banana peels
Banana skins help seedlings grow strong and beautiful. This is due to its rich chemical composition. Many people know that these fruits contain a lot of potassium, but in addition to this element, they also contain a whole complex of useful minerals and vitamins. Moreover, banana peels contain much more of them than pulp. But a person is unlikely to chew the skins, but plants will definitely like them.
As a result of peel rotting, the following enters the soil:
- Potassium is the most - about 8%. The element stimulates the growth of ovaries (together with calcium and iron), the development and ripening of fruits and helps to increase sugars in the pulp, strengthening seedlings.
- Manganese prevents the accumulation of nitrates, takes part in the delivery of nutrients, promotes the accumulation of vitamin C in fruits and is involved in photosynthesis (like magnesium).
- Calcium has a positive effect on the root system of plants, stimulates shoot growth and fruit formation.
- Iron is necessary for the full growth of young seedlings.
- Phosphorus is involved in flowering and fruit formation, strengthens roots, ensures nitrogen absorption, and regulates metabolic processes.
- Magnesium is responsible for the complete nutrition of plant cells, ensures the absorption of phosphorus, participates in the formation of ovaries and stimulates the ripening of fruits.
And, in addition, the peel contains some nitrogen.
Using ordinary banana peels can result in vigorous flowering and plant growth, as well as a subsequent increase in the number and size of fruits several times. No gardener would dare throw away such a valuable product, except perhaps in a compost pit.
The growth hormone present in the shell also contributes to vigorous development. Because the fruits are picked far from ripe in order to transport them to the place of sale and not lose profit from the sale - they are treated with a special solution to ripen them at the time of sale. Thanks to this, banana peels are ideal for seedlings that need constant, complete vitamin nutrition. Seeds in soil fertilized with skins germinate faster, seedlings take root well and develop fully.
Feeding banana seedlings, what are the benefits?
Let's look at what banana peels are rich in:
- Potassium, necessary for the growth of the root system, distribution of nutrients and water, budding and flowering, and the health of plant crops.
- Phosphorus is a source of energy, an essential element for respiration and photosynthesis, ensuring the formation of seeds, and increasing the percentage of germination.
- Calcium, which strengthens stems and roots, is of great importance for the water balance of cells, the absorption of essential nutrients, and increases resistance to many diseases.
- Magnesium, a guarantor of photosynthesis, helps produce chlorophyll, activates certain enzymes, and participates in the synthesis of sugars and carbohydrates. In addition, magnesium will provide a rich harvest and promote root growth.
- B vitamins, tannins, organic acids, pectins, enzymes.
Pros and cons of banana peel fertilizer
The benefits of banana “clothes” for seedlings are obvious:
- promotes the growth of the root system and strengthening of the entire plant;
- promotes the complete absorption of water by sprouts and nutrients, distributing them evenly throughout the living organism;
- strengthens the immune system and promotes resistance to negative environmental influences;
- in fruits it increases the sugar content many times over;
- you don’t have to calculate the correct proportions, because... elements are automatically distributed throughout the plant by nature;
- quickly decomposes in soil;
- makes up for the lack of lighting in winter and early spring;
- due to the natural nature of the fertilizer, you can water the seedlings without fear of burning the stem and leaves;
- repels aphids and other pests that cannot tolerate potassium;
- There is no need to spend extra money on purchasing potash fertilizer; moreover, it does not contain chemicals and the product is easy to accumulate.
The banana shell plays an important role at all stages of plant growth:
- copes well with feeding sprouts that have formed 2-4 leaves;
- has a positive effect on the adaptation of plants to greenhouse conditions and growth in open ground, applied 7-10 days before transplanting;
- the fertilizer maintains the balance of phosphorus and potassium during scheduled fertilizing during flowering and fruit formation;
- actively stimulates the formation of ovaries.
- application during the process of fruit ripening guarantees an increase in the size of the fruit and an increase in the sweetness of their pulp.
However, banana peel fertilizer has many opponents who provide compelling arguments against its use:
- high toxicity due to spraying exotic fruits with a chemical composition to slow down their ripening, which does not accumulate in the banana pulp, but remains completely in the peel;
- you will have to immediately start processing banana skins, because... they quickly decompose, but they still need to be prepared and cleaned of chemicals;
- attract harmful insects that like bananas and are not afraid of the increased potassium content - these are flies, ants and other lovers of sweets.
If previously banana peels were mainly used to feed indoor plants, now the number of gardeners using the skins of the exotic fruit when growing seedlings and seedlings is increasing every season. The peel is useful for any crops, but it is especially valuable for greenhouse and winter plants. Tomatoes and cucumbers, katran and cabbage, rapeseed and leftover, horseradish, peppers and eggplants respond best to fertilizer.
Why can't you use water infusion?
An infusion of banana peels is used as a top dressing for adult tomatoes in garden beds or greenhouses. It cannot be used for watering seedlings due to insufficient fermentation. Unnecessary, even harmful to the crop, organic compounds cannot completely decompose without the presence of a catalyst.
The bulk of banana peels consists of sugars, fiber, and starch. And many, many other chemical elements and compounds. Not all of them are desirable as fertilizer for tomato seedlings:
- Banana peels contain tannins. These are tannins that have a depressing effect on all plants, including tomatoes. It is not for nothing that nothing takes root under a walnut, and birch and hazel are considered bad neighbors. In tomato seedlings, tannins will, at best, slow down their development, and at worst, destroy them.
- Banana peels also contain powerful growth stimulants. Is this necessary at the initial stage? In young tomatoes, excessive growth of the above-ground part always occurs due to the development of the root system. Planting material dealers even treat their goods with Atlet-type regulators to keep the tomatoes small and strong.
- Sugars, which banana peels contain much more than minerals, attract insects. Even sciarids, which are harmless to indoor flowers, can damage tomato seedlings. They happily lay eggs in containers with tomatoes fertilized with banana peel infusion.
- Skins that are flooded with water and contain a lot of carbohydrates begin to ferment, but cannot go through the full fermentation cycle. If you fertilize adult tomatoes with a weak yeast solution, they will not only receive additional nutrition, but also prevent fungal diseases. For seedlings, this can be disastrous. Moreover, yeast fungi “eat” potassium and calcium from the soil.
- Starch and pectins from banana skins reduce the permeability of the substrate, impairing the supply of water and oxygen to the roots. But they cannot wash into the lower layers of soil when watering - the system is closed, limited to a pot or box.
Tannins and stimulants somewhat neutralize each other, and starch and carbohydrates are partially decomposed during weak fermentation. But only if the banana peels were kept warm. And the degree of decomposition is unpredictable. For immature young tomatoes, the impact of these substances is a huge stress, and soil compaction and a decrease in potassium and calcium content are generally unacceptable.
Ways to use banana peels as fertilizer
Many gardeners use only 1-2 methods of preparing banana shells at home for seedlings. Basically, this is the simplest thing - burying the crushed (or even whole) shell into the ground, which after a week almost completely decomposes, giving all the nutrients to the soil and plants. It is better not to leave the peel on the surface of the soil - it will become moldy and instead of doing any good, it will harm the plants. There are several different recipes for preparing seedling fertilizer, each of which is effective.
Drying the peel in the oven or naturally
The oven drying method is very simple:
- cover a large baking sheet with foil, where the peel is then placed with the inside side up so that it does not stick to the surface;
- the baking sheet is placed in the oven (ideally, when something is being cooked in parallel, so as not to spend money separately on gas);
- After checking the skins for readiness - they must be completely dry - they should be cooled and placed in pre-prepared containers or bags.
After drying, the banana skins are ground in a blender and poured into a jar (bucket - when producing large volumes) or placed whole in a bag. For each sprout you will need 1 spoon of dry fertilizer. Or prepare a mixture: dried peels of 4 bananas are mixed with 3 tsp. powdered eggshells (can be mixed with ash), 1 liter. water and 20 g of magnesium sulfate and shake. All seedlings are sprayed with this product once a week.
During the drying process, unfortunately, a small part of the nutrients evaporates along with moisture.
If you dry the banana “coat” naturally, all the elements are preserved, but you will have to wait several days for complete drying. When laying it out on a windowsill or radiator, it is advisable to cover the future fertilizer with gauze, protecting it from insects and it is important to prevent the product from rotting. Some gardeners hang the skins on strings outside on the sunny side, adopting the drying method from mushrooms.
Liquid banana infusion with water
The peel is pre-cut into pieces or placed whole in a jar. Pour water at room temperature and leave for at least 3 days. The strained infusion is diluted with water 1:1 and poured over seeds, seedlings or adult plants. There are several recipes with certain proportions:
- The shell of 1 banana is crushed, mixed with a glass of water in a blender and immediately (or after infusing) add 2 tablespoons per plant once every 30 days.
- The peels of 3 bananas are placed in a 3-liter jar, filled with water, and closed. Leave for 2 days. After a while, filter and use as intended.
A tincture in water will require only cleanliness of the container in which the peels are placed, and even, most likely, sterility so that the skins do not become moldy. If the infusion has darkened, it must be strained immediately. Liquid fertilizer made from banana peels is universal, convenient to use and suitable for all types of seedlings.
Frozen peel
If your freezer allows you to make room for banana peels, this is a great way to easily put the peels aside until spring and preserve their beneficial properties. In addition, when frozen, all harmful chemical elements disappear.
Freezing is a great way to collect the skins for a long time and store them in a separate tray in the freezer, receiving a fertilizer that is unique in its composition completely free of charge in the summer.
Banana compost
In a month you can get excellent compost from banana skins for tomatoes or other garden crops. To do this, just add chernozem to the skins of the fruit, pour in “Baikal” or something similar and mix everything. After 30 days, you can lay compost for any garden crops, except for greens, cabbage and root vegetables. All bulbs grow especially well with this fertilizer. Seedlings of tomatoes and cucumbers, eggplants and peppers on such a fatty diet quickly get used to a new place and produce unprecedented yields.

Using Yeast
Important! Enhances growth and development. Apply no more than 2 times due to excessive stimulation of vegetation.
Yeast is rich in:
- Amino acids.
- Proteins.
- Minerals.
When watered with a yeast solution, tomatoes tolerate picking easier, roots grow 10-14 days earlier.
Base for the solution:
- 10 g yeast in dry powder form.
- 3-5 tbsp. Sahara.
- 10 liters of water.
Before watering, the concentrate is diluted 1 to 10. A good effect is achieved by combining yeast with ash and mullein extract.
Ash
Contains more than 30 components. It is the record holder for the level of potassium-phosphorus tandem. In addition, the composition contains active elements:
- Calcium.
- Zinc.
- Iron.
- Sulfur.
- Bor.
- Magnesium.
Not everyone knows how to properly dilute ash.
In fact, everything is very simple, the ash solution consists of :
- 100 grams of powder.
- 10 liters of water.
This is a very good fertilizer that can be used both for seedlings and for fertilizing adult plants. Ash also helps get rid of many insect pests.
Hydrogen peroxide
3% peroxide is a popular means of stimulating seedling growth. It can be used to both water and spray seedlings . The drug supplies tomatoes with oxygen necessary for metabolic processes. Using peroxide:
- Prevent infections.
- Accelerate flowering.
- Saturate with oxygen.
- Eliminate pests.
- Strengthens roots.
- Prevents putrefactive processes.
To prepare the solution, dissolve 10-15 drops in 1 liter of water.
Banana peel
Banana peels are a valuable source of potassium and manganese; they contain 78 mg/g and 76 mg/g of useful microelements, respectively. The skins are dried on a radiator, having previously been cut into strips 1 cm wide. For 3 liters of water you will need 4-5 banana peels . Before watering, dilute 1 to 1.
Fertilizer saturates the soil:
- Proteins.
- Carbohydrates.
- Iron.
- Magnesium.
- Gray.
- Phosphorus.
- Calcium.
Ammonia
10% ammonia is necessary for pale and weakened young seedlings. Important nitrogen supplier.
For the working solution, ammonia is diluted in the following proportion: 1 tablespoon per 1 bucket of water. If it is a 25% solution, then you will need 1 teaspoon .
Watering is carried out strictly in the root zone.
Eggshell
It is a natural source of potassium, calcium, phosphorus. The shells of 2-3 eggs are crushed with a rolling pin. Pour into a container with 3 liters of water and leave for 3 days . Before watering, dilute 1 to 3.
Beer
Used for the first feeding. Beer actively stimulates growth and has an effect similar to yeast. For the working solution, mix:
- 1 liter of live beer
- 10 liters of water.
When watering, try to avoid contact with delicate leaves.
Onion peel
20 g of dry scales without signs of rot are poured into 5 liters of water. Leave for 4-5 days. Then the infusion is filtered and it is ready for use.
Bread
Soak 2 kg of bread in 10 liters of water. Leave for 5-7 days while intensive fermentation occurs. Baikal EM is poured in. Strain and dilute 1 to 10.
Serum
Natural natural fertilizer contains, in addition to protein, lipids, lactose, amino acids, a wide range of minerals. Leading:
- calcium,
- phosphorus,
- potassium,
- nitrogen.
Used for root feeding and irrigation. Diluted in a ratio of 1 to 4 or 5.
Iodine
Iodine solution increases the immunity of seedlings, strengthens fruiting clusters. Used for root watering and spraying. The product for applying under the roots consists of:
- 5 drops of iodine solution.
- 10 liters of water.
According to farmers, the use of iodine provides many advantages:
- Improves shoot growth.
- The fruits grow much larger.
- Product performance, shelf life, and transportability are improved.
- The incidence of bush diseases is reduced
Foliar spraying prevents infection by fungi - powdery mildew and late blight. The solution is prepared - 1 drop per 3 liters.
Preparing banana peels for use
When buying bananas and storing their “clothing”, do not forget about the numerous ways to process tropical fruits. All harmful components will remain in the peel if the future fertilizer is not pre-treated.
Washing and even soaking in boiling or hot water may not completely remove all the chemicals, but freezing will deal with all of them without exception, while preserving the nutritional properties of banana skins. Therefore, there is no need to rush to feed the seedlings with this unique fertilizer; it is better to freeze it for several days and only then scatter it around the garden.
By following this simple rule, you can protect your seedlings from harmful substances by fertilizing them with an almost free natural remedy.
Symptoms of nutritional deficiency
Due to a deficiency of minerals, seedlings are stunted in growth, bushes have weak trunks, leaves turn pale, become spotted or curl. Depending on the type of element deficiency, characteristic manifestations appear:
Mineral deficiency | Signs |
Bor | Retarded growth and development Dying off of the growing point Stormy vegetation of side shoots |
Nitrogen | Discoloration of the leaves . Veins and stem of a reddish tint. |
Potassium | Bush growth slows down Signs of necrosis appear on the leaves The trunk is sluggish, weak |
Phosphorus | Roots develop poorly Leaves dry out |
Magnesium | The leaf blade turns yellow along the veins. The edges of the leaflets are bent. |
Zinc | Gray-bronze spots Leaves become smaller and covered with yellow specks |
More fertilizer recipes for seedlings with banana peels
If, before planting seedlings in the soil, you feed the soil with a banana-citrus cocktail made not only from the peels of exotic fruits, but also citrus fruits, the plants will receive even more nutrients and beneficial substances, which will have a great effect on yield growth. The growth elixir for plants is prepared as follows:
- you need to take the crushed peel of 1 banana, the zest of 1 orange (they should have equal proportions with the peel) and 1 tbsp. l. Sahara;
- the ingredients are placed in a 3-liter jar, filled with water at room temperature and closed;
- wait 3 weeks, then filter and mix with water in proportions of 1:20.
The tincture is used to feed seedlings and plants once every 30 days.
You can read and reread for a long time different ways of creating and using fertilizers from banana peels, but it’s better to try it once and put it into practice. A productive year is guaranteed.
For peppers, cucumbers and tomatoes
Banana peels are perfect for planting vegetables. Just place pieces of skins in pots with plants when picking. The banana peel should be finely chopped.
If you need to treat already mature seedlings planted in a bed, try lightly digging the soil around the roots of the plants and placing pieces of banana peel there. After two weeks, it will decompose, and useful substances and microelements will remain in the soil, which will positively affect the growth of your fruits.

How to feed
Seedlings are fed in 2 main ways:
- Root watering . They are carried out quickly and improve the soil composition. Can be applied in the form of solutions or in dry form. They use organic matter, potassium sulfate, superphosphate, nitrogen compounds and complex preparations.
- Foliar spraying . Nutrition immediately enters the tissue. The effect comes quickly. Concentrates require precise dilution to avoid burns. The bushes are irrigated with solutions based on dairy products, ash, ammonia, complex minerals, and combined mixtures.
Precautionary measures
Before using tropical fertilizer in your garden, read the following warnings:
- The peel is a kind of “biofilter” of bananas. These smart plants do not accumulate foreign substances in the pulp.
- Banana peel is not a universal fertilizer that can replace all fertilizers. It is a source of only potassium, phosphorus and calcium. But plants also need nitrogen, of which there is a small amount in bananas.
- If you have accumulated fruit peels from suppliers whose integrity you are not sure of, do not throw them away. This peel is suitable for fertilizing tomatoes, eggplants, and sunflowers. These crops, like bananas, also have “biofilters” that prevent the accumulation of harmful substances in the pulp.
- Fertilizing with fresh banana skins is more recommended for seedlings and young plants. To fertilize plantings that are at the stage of flowering and fruiting, it is better to use dried, fried, dried skins
- It is recommended to place raw peels under seeds and the root system of seedlings, but not under adult plants. You shouldn’t mulch the soil with banana peels either.
- Leaving raw peels on the soil surface is a big mistake. It will not release useful substances to the substrate, but will begin to mold. Such a decomposing product will attract uninvited sweet lovers - ants, fruit flies and others.
- You can prepare banana fertilizer in a lot of ways - fry it in the oven, microwave oven, dry it on a radiator, window sill, freeze it in the freezer, brew it like tea and scald it with boiling water. But the best way is drying in the fresh air. With this approach, most of the useful components and growth stimulants will remain in the raw materials, and unnecessary (or even harmful) organic matter will evaporate. I cut the skins into thin long strips 1-2 cm wide, tie them by the tails, like mushrooms, and hang them on the sunny open veranda. I start making preparations in the spring - for drying, a temperature of 15 C is enough.
Wash the fruit skins very thoroughly before use - in hot water and soap. After all, when harvesting, bananas are soaked in vats with solutions of ammonium sulfate and chlorine to remove the milky juice.
It is also important not to “over-fertilize” the plants with banana treats. Let me present the norms for feeding:
- Greenhouse crops: ½ cup for tomatoes, ¼ cup for cucumbers.
- Ornamental plants: half a glass or a whole glass per bush. There is no need to feed more than once every 1-2 weeks.
- Indoor flowers: 1-2 tbsp. spoons of fertilizer per 2-3 liter pot. Fertilizer frequency: once a week.
Banana peel is an excellent and economical remedy for the garden, vegetable garden and home. Among the sea of its applications, one of the most valuable is fertilizing seedlings, indoor and greenhouse plants, and open ground plantings. Use fresh, dried, dried fertilizer, make banana decoctions, infusions and cocktails. The most important thing is not to forget about precautions when using such fertilizer.
In what cases should you not feed?
The principle for tomato seedlings is that it is better to underfeed than to overfeed. There are a number of indications when fertilizing should not be carried out temporarily:
- Overfeeding with nitrogen fertilizers.
- Fattening of seedlings.
- Excess of phosphorus-potassium fertilizers.
Seedlings are fertilized at least 3-4 times. Particular attention is paid to complex, adapted formulations and preparations with nitrogen, phosphorus and potassium. A good help are folk recipes that any gardener can prepare.
Common mistakes when using
Cultivating and feeding tomato bushes in the early stages is a delicate matter that requires certain knowledge. What are the violations that worsen the quality of seedlings:
- Wrong dosages.
- Wrong choice of fertilizers.
- Abuse of nitrogen mixtures.
- Failure to meet deadlines. Too soon or too late.
You cannot combine in 1 feeding:
- Ammonium nitrate, superphosphate, urea.
- Superphosphate and lime.
- Manure and ammonium sulfate.
Rules for using additives
When applying fertilizing, strictly follow the instructions and recommended doses. Young bushes are adversely affected by both deficiency and excess nutrition.
There are a number of rules for fertilizing:
- Solution concentration . All industrial and folk remedies are diluted before application. See the instructions for proportions.
- Dosage . To avoid overdosing on ingredients, carefully check the dosage on the package or in the recipe.
- Time . Carry out in the morning after watering. This is important to prevent fungal infections.
- Form . Solutions and dry mixtures are used after preliminary dilution.
- Watering . After each root application, the seedlings are watered with settled water to wash away any preparations that have gotten on the trunk and leaves.
