Make fertilizer yourself for a bountiful harvest and beautiful flowers in the garden : The best fertilizer is the one you make yourself, using simple home remedies that you can find in your pantry, garbage can or garden. In this article you will learn how to make a wonderful fertilizer yourself from kitchen and pantry scraps for your plants.

Make your own fertilizer: It’s crucial to know what NPK is

Make your own fertilizer - what basics to consider

Even if you’re a novice gardener, you’ve probably heard of the acronym NPK, considered a holy relic by experienced greenkeepers.

NPK stands for nitrogen, phosphorus and potassium. Although your garden needs a variety of micronutrients to thrive, these three are the most important macronutrients that make for a healthy and lush garden.

The NPK ratio (listed as 16-5-5 on a bag of synthetic or organic fertilizer) is essentially the ratio of nitrogen, phosphorus and potassium. In the 16-5-5 example, it means that there are 16 kg of nitrogen, 5 kg of phosphorus and 5 kg of potassium.

  • Nitrogen is particularly useful for increasing yield and accelerating plant growth.
  • Phosphorus is useful for plant growth, such as the growth of fruits and flowers, and for the formation of thick leaves and strong roots.
  • Potassium is a versatile soil conditioner that helps plants retain water, resist pests and diseases, and produce proteins needed for growth.

What home remedies are rich in NPK

Compost – the optimal fertilizer.

Nothing restores soil fertility as well as compost

Phosphorus, potassium and magnesium make up a large part of compost. The advantages of home composting are numerous. First of all, there is no better method than natural fertilization in home gardens and even on smaller farms. Nothing restores soil fertility as well as compost. It is especially suitable if your garden has been depleted by the use of chemicals.

Compost has another important purpose: it can be used as a natural cover for overwintering plants in the garden.

Last but not least, compost contributes to the ecological balance in the urban environment, as households store their own biodegradable waste instead of disposing of it with the residual waste.

In general, compost is a collection of most natural wastes in a household:

  • Straw
  • Paper
  • Leaves and twigs
  • Egg shells
  • Fruit and vegetable waste
  • Freshly mown grass – it should be remembered that it adds a lot of moisture to the compost

The principle of composting is not complicated at all. To do this, you need to set up a place in your garden with the minimum dimensions of 1 x 1 x 1 m and pile organic waste there. The smaller the pieces of garbage you throw away, the faster the decomposition process will start.

From coffee grounds you can make a wonderful fertilizer yourself

You can make a wonderful fertilizer yourself from coffee grounds

Ground coffee is an excellent source of cheap and easy nitrogen. It is also pest repellent and makes a great mulch material.

Coffee grounds have many uses, but one of the best is as fertilizer. Many plants, such as blueberries, rhododendrons, roses and tomatoes, do best in acidic soil. Recycle coffee grounds to acidify your soil. There are several ways to do this: You can feed the soil with used sewage sludge by sprinkling it on the surface of the soil, or you can make “coffee” to pour over your gardens. Soak up to six cups of used coffee grounds for up to a week to make garden coffee, then use it to water your acid-loving plants.

Organic fertilizer made from bone meal is high in phosphorus

Organic fertilizer from bone meal contains a lot of phosphorus

Bone meal fertilizer, also known as organic bone meal, is a type of organic fertilizer made from animal bones. Bone meal is a by-product of the slaughterhouse, where cattle bones are ground into fine powder or made into pellets. Bone meal fertilizer contains elements that can improve the health of flowering plants such as roses and tulips.

Bone meal is a useful fertilizer for the garden with several benefits:

  • Bone meal fertilizer increases the phosphorus content in the soil. It is an excellent source of phosphorus needed for photosynthesis in your plants.
  • Bone meal is a slow release fertilizer. It is released over a period of several months. Bone meal can increase the number of soil microbes during the growing season, which benefits the soil structure for your plants’ root system.
  • Bone meal provides calcium for your plants. Calcium improves root growth, promotes strong roots and helps prevent blossom end rot.
  • Bone meal can balance other soil amendments. Consider mixing bone meal with other nitrogenous amendments, such as manure.
  • Bone meal is an organic fertilizer. Unlike chemical fertilizers, bone meal improves your organic gardening by using natural elements.

Banana peels are rich in potassium

Make fertilizer yourself - banana peels are rich in potassium

Both the fruit and the peel of bananas are rich in potassium. There are numerous ways to get the nutrients from a banana peel. You can mix it and incorporate it into the soil, or soak it for a few days to create a “tea” that you spray on your plants.

Or you can simply bury a bowl in your garden near the roots of the plants you want to nourish. However, for the most complete application, we recommend drying and crushing it to get the nutrients you want to the plant’s root system quickly and efficiently.

Make your own fertilizer: nourish plants with micronutrients from your household.

How to make a wonderful fertilizer yourself from kitchen scraps

While synthetic fertilizers and many organic fertilizers are overly concerned with NPK ratios, the micronutrients your plants need can sometimes take a back seat.

Here are some of the easiest ways to provide your garden with all the elements it needs to be healthy and fertile.

Eggshells are full of calcium

Provide your garden with calcium through eggshells

If you’ve ever used lime in your garden, you know it has many benefits – predominantly, it helps reduce soil acidity for plants that don’t like acids, and provides plants with plenty of calcium, an important nutrient. Lime itself is a completely natural fertilizer that you can buy at the garden center.

However, if you’d rather save some money, there is a cheaper way to get the same benefits. Next time you make an omelet, save the eggshells for your garden. By drying the shells and grinding them into a fine powder, you’ll ensure that your garden gets the calcium it needs!

Make your own fertilizer: Epsom salt is rich in magnesium

Make fertilizer yourself - tips for home remedies that you can use.

Epsom salt is the main source of magnesium sulfate, an important mineral for the body and the soil. Magnesium has a variety of roles, but the most important is to support chlorophyll production during photosynthesis.

Caution: too much magnesium can lead to calcium or potassium deficiencies and acidify the soil beyond a healthy acidity level.

Aquarium water is an excellent all-purpose fertilizer.

Aquarium water is an excellent all-purpose fertilizer

If you have fish, you’ve probably noticed that the water gets a little cloudy from time to time. Sure, that means you’ll need to clean the aquarium soon, but it also means your fish are giving you phenomenal fertilizer, and for free. Aquarium water is a great all-purpose fertilizer and can be sprayed directly onto plants or poured into the bottom with a watering can.

Make your own fertilizer: Borax against boron deficiency

Borax against boron deficiency in the soil

Although borax is bad news for ants, it is actually quite beneficial to the soil, in limited amounts. Boron deficiency is difficult to detect because its contribution to the total nutrient composition of the soil is so small. Chlorosis (yellowing of leaves) is a symptom of boron deficiency, as are large numbers of spindly, brittle stems.

Dried seaweed for soil improvement

Dried seaweed is a brilliant soil conditioner

Dried seaweed is a brilliant soil conditioner. Also, seaweed is plant matter that should not decompose in the soil, so you don’t run the risk of attracting animals with the smell.

Molasses contains many nutrients for plants

How to make your own fertilizer - molasses contains many nutrients for plants

Molasses is a product of sugar beets, which are rich in nutrients. Almost every house has molasses somewhere in a dusty corner. It’s just one of those basic household products that you eventually forget about. Why don’t you put it to good use?

Tea for fertile soil

Tea leaves are rich in antioxidants that improve the soil

You’ve probably heard about the positive effects of tea on human health. Well, it’s not bad for your plants either.

Tea leaves are rich in antioxidants. They also contain tannic acid, which helps make the soil a more fertile environment for your plants. They also help build soil structure as an organic material, making it easier for your plants to get the water and nutrients they need.

Make your own fertilizer with yeast for delicious vegetables

Make your own fertilizer with yeast for tasty vegetables

For a bountiful harvest, all you need is this natural fertilizer that’s a vitamin bomb for the whole garden. Use it for vegetables and fruits like tomatoes, cucumbers, eggplants and strawberries, but also for plants like petunias and nutmegs, for example.

If you want to use a natural fertilizer in your garden, yeast is the ideal choice for your plants. In addition to beneficial microorganisms, it contains phytohormones and B vitamins. Your plants will reward you abundantly.


  • 100 g sugar
  • 100 g fresh yeast
  • 3 l hot water
  • 10 l of standing water for dilution
  • 3 liter container with lid
  • Sprayer with a capacity of 3 liters

Pour hot water into the container. Do not fill it to the brim, but leave a little space. Add the sugar and the crumbled yeast. Stir well so that everything dissolves.

Cover the container with a plastic lid. Let the solution ferment in a warm place between 4 and 7 days. After this time, shake well and dilute 100 ml in 10 liters of standing water.

Water the plants with the diluted solution. You can pour it directly into the roots or spray the leaves. Use this fertilizer early in the morning or in the evening, when the sun is not yet so strong.

Make your own fertilizer: solve pH problems with home remedies.

Compost is the optimal fertilizer

Simply put, if your soil is balanced (or as close to neutral pH as possible), your garden will be much healthier overall than if your soil swings one way or the other.

Soil pH is measured between 1 and 14, with 7 being completely neutral. For comparison, proper compost is measured at 7 on the pH scale – or at least very, very close to it.

If you don’t want to risk the health of your garden while you wait a few weeks for compost to mature, you can take some temporary steps to bring your soil back to a neutral pH.

Vinegar for acid-loving plants

Spray vinegar for acid-loving plants

So technically, acid is not a specific nutrient in the soil, but a balanced pH is extremely important for your garden. Acid-loving plants like blueberries, tomatoes, rhododendrons, roses and other large and bright species especially benefit from a vinegar spray .

Wood ash balances the pH of the soil

Do it yourself fertilizer - wood ash balances the pH of the soil

Unlike acid fertilizers, you should adjust the soil to a more alkaline pH. This is advisable if you are trying to grow asparagus or artichokes (among a variety of other alkali-loving plants) with little success.

Wood ash is an easy substitute for lime, which is a common fertilizer in agriculture and helps balance soil pH and add magnesium and sulfur.

Bottom line: a healthy fertilizer/compost balance.

Make your own fertilizer for a rich harvest

The point is this: You can enrich your soil with fertilizer all you want, but it won’t give your garden the same benefit as simply building a compost pile and using the nutrient-rich byproduct as a soil amendment.

Fertilizers are quick-release nutrient additives. Compost provides a longer lasting and more complete form of nutrient release. This is because the nutrients in compost have not yet completely broken down and will continue to decompose in the soil as they are added to the garden, releasing nutrients over time.

In addition, compost has an almost perfectly balanced pH, which helps to balance the soil and make it easier to grow a lush garden.

However, if you don’t want to wait until the compost is ripe, you can always use the fertilizer recipes above to give your plants a boost when things get tight.
