7 Natural Nitrogen For Plants Homemade (2024)


Nitrogen for Plants Homemade: A Natural and Affordable Solution

In the field of agriculture/gardening, there are three main nutrients that are necessary for plants to grow nitrogen, phosphorus, and potassium. There are many nitrogen-based fertilizers available in the market that you can buy but sometimes they are expensive. You can use natural nitrogen for plants homemade which is cheaper.

In this article, we will discuss home-based products which are rich in nitrogen. Nitrogen is the most important nutrient which plants need to grow. Plants need nitrogen to grow leaves and increase the process of photosynthesis.

Why Nitrogen is Important for Plants?

Nitrogen is the most important nutrient for the growth of plants. Proteins, enzymes, and chlorophyll all need nitrogen to develop properly. The process of photosynthesis also depends on nitrogen. Sunlight is absorbed by the plants, and then use it to produce energy.

Direct nitrogen absorption by plants from the atmosphere is not possible. The plants rely on soil bacteria for nitrogen. This procedure is known as nitrogen fixation.

Signs of Not Enough Nitrogen:

  • Leaves turn yellow and droopy.
  • Plants look small and weak.
  • Flowers don’t bloom as much.

Why Nitrogen For Plants Homemade Is Great?

Environmental friendly:

Nitrogen for plants homemade comes from daily kitchen waste you have at home. Homemade nitrogen helps all the good bugs and creatures in your garden, making your plants even happier

Saves You Money:

Instead of buying costly chemical fertilizers from the market, you can create your own plant food at home using the kitchen waste you already have.

Homemade nitrogen for plants: Common Household Ingredients Rich in Nitrogen

You can make nitrogen plant food with ingredients from your kitchen and garden.

Coffee Grounds

Do not throw away the grounds that have been used after making coffee. The plants love them! Your plants will receive a slow and constant supply of nitrogen. You can use old coffee grounds as a source of nitrogen for your plants by mixing them right into the soil around the bases of the plants. The decomposition of the coffee grounds will gradually release nitrogen, giving the plants a natural and slow-release nitrogen fertilizer.

Nutritious Banana Peels

Banana peels are a good source of nitrogen for plants. It is advised to cut the peels into small pieces to accelerate the decaying process. Then, dig small holes near the base of your plants and bury the banana peel pieces in the soil. Once the banana peels start to decompose nutrients like nitrogen and potassium are released into the soil. You can increase soil fertility and healthy growth of plants, without using chemical fertilizers.

Before using the eggshells clean the eggshells to remove any residue that can cause fungus. To increase decomposition speed crush the eggshells into small pieces. Eggshells contain calcium and nitrogen, which are released throughout the process of decomposition. Using eggshells as fertilizer improves the soil fertility. You can provide nitrogen to your plants in an economical way and using eggshells as fertilizer is completely environmentally friendly.

Utilizing green waste for a nitrogen boost from the Kitchen and Garden

Grass Clippings

Keep your lawn’s clippings after mowing it. They have lots of nitrogen. After mowing, gather the fresh clippings and create a thin layer around the base of your plants. As these clippings decompose naturally, they release valuable nitrogen and other nutrients, nourishing the soil and supporting plant growth. This organic mulching method not only acts as a slow-release fertilizer but also aids in moisture retention and weed control, fostering robust and vibrant plant life in your garden. Embrace this sustainable practice for a thriving and beautiful green space.

Nitrogen Booster: Leguminous Plants

Beans and peas have a unique capability to form a symbiotic bond with bacteria in their roots that fix nitrogen. These plants are able to absorb nitrogen from the air and transfer it to the soil. Leguminous plants will organically raise the soil’s nitrogen content in the garden.

As these plants grow, they release nitrogen into the soil, helping the surrounding plants. This natural nitrogen enrichment is a practical and environmentally friendly solution to increase the fertility of your garden.

Composting: The Secret Recipe for Nitrogen-Rich Soil

Composting is also an easy way to provide nitrogen to your plants. To make compost collect the leftovers of fruit and vegetables from the kitchen, and garden waste, such as grass and leaves. In a compost bin, combine both kitchen and garden waste. Compost releases nitrogen when it decomposes.

Use this nitrogen-rich compost in your plants to increase their growth. Composting is an easy and efficient technique to recycle garden and kitchen waste.

More Nitrogen Booster: Treats for Your Plants

Nettle Leaf Tea

Make nettle leaf tea by leaving dried nettle leaves soaked in water for several days. This tea can be used to provide plants with nitrogen. Water and tea should be combined until the tea color becomes light. Use this combination to water your plants directly. The nettle tea enriches the soil by adding a natural and organic nitrogen boost.

Use Homemade Nitrogen For Plants Wisely

Use with Care: Don’t overuse it

Using too much nitrogen for plants homemade can create unique challenges in your garden. Overdoing it can disrupt the balance of nutrients in the soil, harming plant growth. Your plants may suffer from “fertilizer burn,” damaging their roots and leaves. Excess nitrogen can wash away with rainwater, causing pollution in water bodies. Unwanted weeds might thrive, competing with your plants.

To avoid these issues, apply homemade nitrogen carefully, following guidelines and soil tests. This ensures a healthy garden and a greener environment, making your gardening journey truly unique and rewarding.


In conclusion, using nitrogen for plants homemade offers a sustainable and eco-friendly approach to nourishing your garden. Composting kitchen and yard waste, and utilizing leguminous plants are practical ways to supply nitrogen naturally.


Are coffee grounds safe to use on plants directly?

Yes, coffee grounds are safe and can be applied directly to the soil around your plants. They provide a slow-release nitrogen source as they decompose, benefiting plant growth.

What other benefits does compost bring to my garden, besides nitrogen?

Compost offers numerous benefits, including improving soil health, enhancing moisture retention, controlling weeds, and attracting beneficial insects. It enriches the soil with essential nutrients beyond just nitrogen.

Can I use nettle-leaf tea for all my plants?

Generally, most plants will benefit from nettle-leaf tea. However, some plants have specific preferences, so it’s advisable to check their individual requirements before using nettle-leaf tea on them.

Can I use too much homemade nitrogen for my plants?

Yes, using excessive homemade nitrogen can harm your plants. It may disrupt soil nutrient balance, cause “fertilizer burn,” and contribute to water pollution. Apply homemade nitrogen carefully and follow soil testing guidelines.

What are the signs of not enough nitrogen in plants?

Signs of insufficient nitrogen in plants include yellowing and drooping leaves, stunted growth, and reduced flowering.
