Banana peel as a fertilizer for indoor plants and garden

The content of the article

A very useful fertilizer for indoor or garden flowers, for seedlings of vegetables, fruit trees and berry bushes – banana peel. Using top dressing from these wastes, the flowers on the window will please you with abundant flowering, vegetable seedlings will grow strong, because they receive almost all the necessary elements for full development and growth. Many gardeners are already familiar with this wonderful fertilizer, but for someone it will be useful to read this article. Why is a banana peel – this is one of the best bases for the preparation of vitamin top dressing?

The benefits of banana peel for plants

Banana peel as a fertilizer in gardening is not new, it has been used for a long time. The advantages of home-made nutrition, in comparison with store analogues, is that the first product does not contain chemical additives. The use of peel from a banana:

  • microflora improvement and soil health improvement;
  • harmless growth stimulation;
  • strengthening immunity;
  • stimulation of the fight against diseases and pests;
  • saturation with useful trace elements, as a result – plants are less painful to transplant, lack of sunlight and heat.

Chemical composition

The composition of the banana peel is almost similar to the pulp of this fruit, but there are some differences. Minerals contained in the skin are:

  • potassium;
  • sodium;
  • phosphorus;
  • manganese;
  • calcium
  • iron;
  • magnesium
  • nitrogen.

More than 90% of the banana peel mass is accounted for by liquid and organic nutrients (proteins, carbohydrates, fiber, lipids). The amount of water in the skins depends on the time of harvesting, the degree of maturity of the fruit, and the shelf life. Such a component composition has found practical use of banana peels in industrial production.

Almost every mineral or organic component is a useful substance necessary for the normal development and functioning of the human, animal or plant organic system. Their consumption is necessary, otherwise a general malaise of the body develops. Getting nutrients from banana peels should be correct, as they contain some harmful poisonous elements that accumulate in the skin.

Mechanism of action

Having studied the composition of the peel, it is immediately clear that such waste is ideal for feeding plants. The mineral complex, which is part of the fruit and peel, is useful for growth, development, flowering and fruiting. The peel of vegetables and fruits very often contains a rich vitamin and mineral composition – this has become a prerequisite for the use of banana peels in gardening. When all these trace elements decompose, they perfectly nourish the roots, stimulating active growth and flowering.

The skin contains a large amount of plant growth hormone, because fruits are ripened ripened and processed with substances for ripening at the time of sale. Feeding from a banana peel activates seed germination, rooting seedlings, the development of young shoots. This fertilizer is used to stimulate the growth of seedlings of vegetables, to feed greenhouse crops or indoor flowers, especially those that lack solar heat and light. Magnesium contributes to photosynthesis, so it will have to “taste” the winter greenhouse and indoor plants.

Application features

Fresh banana peels contain substances similar in action to papain – used in cooking to soften hard meat, but can destroy the root system. In addition, the concentration of useful components in a fresh product is high, so you can apply a fresh peel only by planting it under the roots, but with a mandatory layer of earth. To make banana skins inactive biologically, while maintaining the mineral composition, in the following ways:

  1. Drying in an oven or microwave with minimal power is not the most suitable way, because most harmful organic decomposition products remain in the product.
  2. Fry in a dry pan, over low heat.
  3. Making boiling water is equivalent to the first method.
  4. Natural drying in the sun or battery – almost all decay and exchange products volatilize, but due to the length of the process, raw materials can rot or ferment.
  5. Freezing in the freezer – the result is similar to natural drying, but rotting or fermentation of the product is excluded.
  6. Scalding with boiling water and insisting for 1-2 hours. After this, the infusion is drained, and a deoxidized substance is used, in which growth stimulants remain, but most of the mineral components are lost.
  7. Drying in the fresh air in direct sunlight – the entire mineral complex, growth stimulants are preserved, and harmful organics disappear.

Fertilizer for flowers

Banana skins, which make up about 35% of the total fruit mass, contain as many nutrients as fruits. According to experienced gardeners, fertilizer from a banana peel for indoor plants activates their growth and protects against diseases. If you familiarize yourself with all the methods of applying the peel in floriculture, you can save money and significantly improve your “green pets”. The banana peel is wiped with leaves of indoor flowers, so it is cleaned of dust.

Such dressing for flowers from a banana peel replaces potassium-phosphorus fertilizers, which has a beneficial effect on the development, growth, budding, flowering of plants. Those flower growers who are accustomed to using industrial dressings can negatively respond to a natural analogue, although banana fertilizers are not inferior to them, for example, humate. If the peels are used in combination with grape shoots, then you can get the most effective top dressing, which contains most of the periodic table.

Feeding seedlings of nightshade and Asteraceae crops

Compositae and nightshade crops have an internal biofilter, so it is recommended to use banana waste fertilizer for sunflower, eggplant, and tomatoes. The result is especially noticeable when using fertilizer in the northern regions of the country. This fertilizer is recommended only for seedlings. During flowering and fruiting, it is recommended to use top dressing from dried or dried crusts.

What plants can I use a banana peel for feeding

Natural fertilizer from banana peels is recommended for the following plants:

Type of raw material

Can be used

Can not use

Raw Banana Skins

Roses, ferns, seedlings of vegetables, cruciferous – cabbage, begonia, senpolia, cyclamen

Bulbs, fruits, and grains (other than suitable)

Roasted, dried peel or banana infusion

Tomatoes, eggplant, sunflower, all indoor, outdoor and garden flowers

How to make fertilizer

The preparation of raw materials takes place in several ways, using:

  • fresh skins;
  • water infusion;
  • dried or dried peel;
  • dry crust powder;
  • fried skins;
  • compost;
  • freezing
  • complex fertilizers from different natural components.

Fresh chopped skins

The simplest, but no less effective way of feeding seedlings or seedlings is crushed fresh skins. To prepare the peel, cut into small pieces and bury it under the root before planting, avoiding direct contact with the roots. After only 7-12 days, the crusts will not leave a trace – they completely decompose, giving themselves to the plant. After such feeding, even weak plants activate growth.

On the surface of the crusts for a long time, the harmful components that the fruit was processed before being sold remain. They must be washed thoroughly before use. It is not recommended to use this method for fruit trees and root crops, as one wash does not get rid of harmful substances. To make fertilizer safer, it’s better to give raw materials.

Dried or dried peel

A simple and easy way to prepare potassium top dressing is to dry the skins in a natural way: in the summer in the sun, in the winter near the battery. Correctly dried peels are completely dry, uniformly dark in color, without black spots and an unpleasant odor. Ready fertilizer is stored in a paper bag or plastic container. Use as needed – bury in a pot when planting a room flower, add to cups when picking seedlings.

You can wilt the banana peels in the sun in limbo in the open air. To do this, banana peel is strung on a string and suspended in a sunny, well-ventilated place, like mushrooms. So, the whole complex of vitamins and minerals is preserved, and there is no trace of harmful impurities.

Dried banana peel

Ground dry skins in powder form

First you need to dry the crusts in the oven, electric dryer or in a natural way. Grind dry raw materials in a coffee grinder or blender. The resulting powder can be directly sprinkled with soil in a flower pot and then poured with water. Repeat the procedure once a month. If mold appears on the surface of the soil after top dressing, then a portion is best applied under the soil, without direct contact with air.


It’s more difficult to make such a fertilizer, but it’s worth it. In a bucket of plain earth, add a lot of banana peels, stir well. Then it is poured with Baikal fertilizer – this is a live top dressing, which does not consist of mineral and organic components familiar to everyone, but of microorganisms. After a month, the crusts and Baikal are re-introduced and mixed well. After 30-60 days, the crusts will decay, a natural compost will be ready.

Water infusion

To prepare a water extract, the peel must be washed, remove the stalks, put in a 3-liter sterile bottle, pour boiled water to the top. All procedures are carried out on a gas furnace or burner. Sterility is important because protozoa, for example, ciliates, can multiply. Soak for 5 days, then the infusion is drained and filtered through cheesecloth. Shelf life of the product is 30-45 days, but the leaven can ferment. Before use, the aqueous extract is diluted with water 1 to 1 and warmed to room temperature.

Application rates

Certain crops may require more or less nutrient, but the usual dose is: 1 tablespoon per liter capacity of the flower pot. The norm may decrease depending on the degree of development of the root system and the type of plant:


For indoor plants

For fruit and berry shrubs and trees

For greenhouse crops


2-3 tsp per pot, if the plant is young, and the root system is weak, then more than 2 tsp. don’t put

100-200 ml per bush

From 50 ml to 100 ml under the root, depending on the type of culture

Feeding frequency

Once a week

Not more than 2 times a week, watered directly under the root

Not more than 1 time per week

Watering flowers

Banana water for flowers is not a universal remedy, each plant is individual. But there are general rules that are recommended to adhere to:

  1. All flowers are fertilized after watering so as not to burn the root system.
  2. Plants that are watered with drip irrigation can be fed constantly, but you need to dilute the finished solution with water twice.
  3. When watering indoor flowers, it is important to monitor soil moisture, as with an increased rate, rotting of the roots is possible.
  4. It is necessary to feed the plants 1 time in 7-14 days, depending on the general condition of the flower.

Recipes of complex fertilizers with banana peel

In addition to banana peels, many other food waste products are used as fertilizer, which nourish and improve disease resistance:

  • onion peel;
  • potato peelings;
  • eggshell;
  • peel of citrus fruits;
  • the remains of brewed tea and coffee.

Eggshell magnesia top dressing

To prepare this fertilizer you will need:

  • magnesia – 40 g;
  • water – 2 l.;
  • dried peel from a banana – 6-8 pcs.;
  • egg shell powder – 4 tsp.

Cooking process:

  1. Grind the dried peels.
  2. Pour all the ingredients into the water.
  3. Stir until magnesia dissolves.
  4. Keep refrigerated. Use as a spray – spray on foliage and soil.

With orange zest

A complex fertilizer that combines the beneficial properties of bananas, glucose (sugar) and orange peel is a natural top dressing for indoor plants. Fill a three-liter jar with 30% orange and banana cleanings. Pour 30 g of sugar, add water. Insist 20 days, stirring every 5 days. After 3 weeks, the infusion is filtered. Before use, dilute with distilled water in a ratio of 1 to 20. It is recommended to feed the plants no more than 1 time per month.

Against aphids on plants

If in the soil around the plant in the garden to instill a few peels from a banana, then the aphids on the foliage will be much less, because these insects do not tolerate potassium. A water infusion is made from skins, which repels aphids and nourishes the plant:

  1. Place peels from three bananas in a 3-liter jar of water.
  2. Insist 2 days.
  3. Then strain the infusion and dilute with water 1 to 1.
  4. Water the plant under the root or spray.

Advantages and disadvantages of banana peel fertilizer

The advantages of using top dressing from crusts:

  1. Banana Skins – A Source of Nutrients Essential for Healthy Plant Growth.
  2. Naturalness of raw materials.
  3. Crusts decompose quickly.
  4. Many ways to use and make skins.
  5. Low cost.

Banana peel, as top dressing, has its drawbacks:

  • Bananas are being brought from distant lands, ripped off by the ripening. So that the fruits ripen, they are treated with chemicals, soaked in a solution of chlorine and ammonium sulfate.
  • Feeding does not completely make up for the deficiency of nutrients.
  • When disposing of banana waste, the advantage turns into a disadvantage: fertilizer from banana skins for fruit crops can be used limitedly or prepared in special ways.
  • For fast ripening, bananas are treated with ethylene, which negatively affects the human hormonal system..
  • The smell of a banana attracts insects – fruit flies, ants, bees.
