DIY Recipe for Organic Miracle Grow

Posted by Jennifer Dixon on 23rd Dec 2025

Creating your own organic plant fertilizer at home is a fantastic way to give your plants the nutrients they need without relying on synthetic chemicals. Below is a simple recipe for an organic “miracle grow” fertilizer made from common household ingredients.

Ingredients

  • 1 cup of used coffee grounds: Coffee grounds contain nitrogen, an important nutrient for healthy plant growth.
  • 1 banana peel: Banana peels provide potassium and phosphorus, which support root development and flowering.
  • 1 eggshell: Eggshells are a source of calcium, which helps support strong plant cell walls.
  • 1 tablespoon of Epsom salt: Epsom salt contains magnesium, which plays an important role in photosynthesis and overall plant health.
  • 5 cups of water

Instructions

  1. Collect and Prepare Ingredients: Gather the used coffee grounds, banana peel, and eggshell. Make sure the coffee grounds and eggshell are dry. Crush the eggshell into small pieces so it can break down more easily.
  2. Create the Fertilizer Solution:
    • In a large container, mix the coffee grounds, crushed eggshell, and Epsom salt.
    • Slice the banana peel into small pieces and add it to the mixture.
    • Pour in 5 cups of water and stir thoroughly to combine the ingredients.
  3. Let It Steep:
    • Cover the container and let the mixture steep for at least 24 hours. This allows some of the nutrients to move into the water.
  4. Strain the Mixture:
    • After 24 hours, strain the liquid into another container using a fine-mesh strainer or a piece of cheesecloth. The remaining solid materials can be added to your compost pile.
  5. Application:
    • Use the liquid fertilizer to water your plants as you would with regular water. Apply every 2–4 weeks, depending on the needs of your plants and their growing conditions.

Tips for Success

  • Storage: Store any leftover fertilizer in a sealed container in a cool, dark place.
  • Customization: You can adjust the recipe based on the needs of your plants. For example, adding more banana peel may increase the amount of potassium in the mixture.
  • Sustainability: This homemade fertilizer allows you to reuse kitchen scraps and turn them into something useful for the garden.

By making your own homemade fertilizer, you can put common kitchen scraps to use while practicing a more sustainable approach to gardening. Enjoy watching your garden flourish with this natural approach!
