DIY Phosphorus Fertilizer Boosting Plant Growth Naturally


In the realm of gardening and agriculture, phosphorus is an essential nutrient that plays a crucial role in various physiological processes of plants. It is a key component in DNA, RNA, and ATP, contributing significantly to energy transfer and storage within plant cells. While commercial phosphorus fertilizers are readily available, many gardeners opt for homemade alternatives to ensure sustainability, cost-effectiveness, and environmental friendliness. In this guide, we’ll explore the importance of phosphorus, the signs of deficiency, and provide you with a step-by-step tutorial on creating your own homemade phosphorus fertilizer.

Understanding the Importance of Phosphorus:

Phosphorus is one of the three primary nutrients needed by plants, along with nitrogen and potassium. It is vital for:

  1. Energy Transfer: Phosphorus is a key player in the process of photosynthesis, aiding in the conversion of light energy into chemical energy.
  2. Root Development: Phosphorus promotes robust root development, enabling plants to access water and nutrients more effectively.
  3. Flower and Fruit Formation: Phosphorus is essential for the development of flowers and fruits, contributing to the overall reproductive success of plants.

Signs of Phosphorus Deficiency:

Identifying phosphorus deficiency in plants is crucial for timely intervention. Common signs include:

  1. Poor Growth: Stunted growth and a general lack of vigor in the plant.
  2. Dark Green Leaves: Leaves may appear darker than usual, indicating a reduced ability to photosynthesize.
  3. Purple or Reddish Coloration: Some plants exhibit purple or reddish discoloration on their leaves, especially in younger foliage.
  4. Delayed Flowering: Phosphorus deficiency can delay the flowering and fruiting stages of plants.

Now, let’s delve into the process of creating your own homemade phosphorus fertilizer.

Homemade Phosphorus Fertilizer Recipe:


  1. Bone Meal: Rich in phosphorus, bone meal is an excellent organic source for your homemade fertilizer. You can either purchase it or make your own by grinding clean, dried bones.
  2. Banana Peels: Banana peels not only add phosphorus but also introduce potassium and other micronutrients.
  3. Eggshells: High in calcium and phosphorus, eggshells contribute to overall soil health.
  4. Fish Bone: If available, fish bones can be added for an extra boost of phosphorus.
  5. Compost: Well-aged compost provides a variety of nutrients and enhances soil structure.


  1. Collect and Prepare Ingredients:
    • Gather sufficient quantities of bone meal, banana peels, eggshells, and fish bones.
    • Clean and dry the bones and fish bones thoroughly.
  2. Grinding and Shredding:
    • Use a grinder or mortar and pestle to grind the bones and fish bones into a fine powder.
    • Shred the banana peels and eggshells into small pieces.
  3. Mixing:
    • Combine the ground bone meal, shredded banana peels, eggshells, and fish bone in a mixing bowl.
  4. Compost Addition:
    • Mix in well-aged compost to enhance the overall nutrient content and microbial activity.
  5. Storage:
    • Transfer the mixture into a sealable container for storage. Ensure it is kept in a cool, dry place.
  6. Application:
    • When ready to fertilize, sprinkle the homemade phosphorus fertilizer evenly around the base of plants.
    • Water the area thoroughly to help the nutrients penetrate the soil.


Creating your own phosphorus fertilizer not only provides a cost-effective and sustainable solution but also allows you to take control of the ingredients you introduce to your garden. Regular application of this homemade fertilizer will contribute to the overall health and vitality of your plants, ensuring they receive the necessary nutrients for optimal growth and development.
