With this simple homemade fertilizer recipe, my orchids have flourished, continuously blooming for the past 10 months. Originally discovered in a gardening group, this versatile mix also significantly enhances the growth of tomatoes, peppers, and other flowers like hydrangeas. Not only have my orchids maintained their blooms, but they have also sprouted an additional flowering stem, promising even more blossoms soon.

I’ve extended the use of this fertilizer to my peppers and tomatoes, and I’ve observed the first buds on my orchids within two weeks of application.

Ingredients for Orchid Fertilizer:

  • Coffee grounds from one cup of coffee
  • 3 banana peels
  • 3 eggshells
  • 1 liter of water
  • Storage container
  • Blender

Key Components:

  • Coffee Grounds: High in nitrogen, they slowly release essential nutrients like magnesium, potassium, phosphorus, and copper into the soil.
  • Banana Peel: Rich in potassium, calcium, magnesium, and phosphorus, banana peels bolster plant strength and pest resistance, while energizing blooms. For quicker seedling growth, soak two peels in a liter of water for two days, then use it for watering.
  • Eggshell: A great source of calcium, eggshells not only nourish tomatoes, peppers, and eggplants but also help protect flowers from rot and are beneficial for composting.


  1. Thoroughly wash and optionally heat the eggshells in the oven or microwave to eliminate bacteria and salmonella.
  2. Finely chop the banana peels.
  3. Combine eggshells, banana peels, and coffee grounds in a blender.
  4. Add a bit of water and blend lightly.
  5. Transfer the mix to a storage container, add the remaining water, and allow it to ferment for two days.

Usage: Apply the fertilizer every 15 days, ideally just before and during the flowering period, and store it in the refrigerator.
