by

Phalaenopsis orchids, also known as moth orchids, are among the most popular and beautiful houseplants. To keep them healthy and vibrant, proper fertilization is essential. Creating your own orchid fertilizer at home can be cost-effective and tailored to your plant’s needs. Here are some DIY fertilizer recipes you can try to promote lush blooms and strong roots.

Basic DIY Orchid Fertilizer Recipe

This simple recipe provides essential nutrients for your orchids using common household ingredients. It is suitable for regular feeding during the growing season.

  • 1 teaspoon of fish emulsion or liquid seaweed fertilizer
  • 1 quart (4 cups) of water
  • Optional: a few drops of liquid vitamin B1 (rooting hormone)

Mix all ingredients thoroughly. Use this solution to water your orchids once every two weeks. Ensure the potting medium is moist but not soggy.

Organic NPK Fertilizer Mix

This recipe combines organic sources of nitrogen, phosphorus, and potassium to support healthy growth and flowering.

  • 1 tablespoon of bone meal (phosphorus source)
  • 1 tablespoon of kelp meal or liquid seaweed
  • 1 teaspoon of potassium sulfate or wood ash (potassium source)
  • 4 cups of water

Combine all dry ingredients in water and stir until dissolved. Use this fertilizer every 3-4 weeks during active growth periods.

Liquid Banana Peel Fertilizer

Banana peels are rich in potassium and other nutrients. This homemade liquid fertilizer is easy to prepare and beneficial for orchids.

  • 2 ripe banana peels
  • 2 cups of water
  • Optional: a teaspoon of molasses for added nutrients

Chop banana peels into small pieces and soak in water for 48 hours. Strain the liquid and dilute with an equal amount of water before watering your orchids once a month.

Eggshell Calcium Supplement

Calcium is vital for cell wall development. Crushed eggshells can be used as a calcium supplement for orchids.

  • Crushed eggshells (cleaned and dried)
  • 1 teaspoon per pot
  • Optional: mix into the potting medium or sprinkle on top

Mix crushed eggshells into the potting medium or sprinkle on the surface. Replenish every few months to maintain calcium levels.

Tips for Using DIY Fertilizers

Always water your orchids thoroughly before applying fertilizer to prevent root burn. Use fertilizers in moderation—overfeeding can harm your plant. Observe your orchids for signs of nutrient deficiencies or excess and adjust feeding accordingly.

For best results, alternate between different recipes and ensure your orchids receive balanced nutrition. Proper fertilization combined with adequate light and watering will keep your Phalaenopsis orchids healthy and blooming beautifully.
