Natural Fertilizer For Houseplants

NATURAL FERTILIZERS FOR HOUSEPLANTS

The Growing Season spans early Spring through early Fall and is the best time to maximize your plant’s growth through routinely fertilizing the soil. Plants need many of the same nutrients we receive from our food, like Nitrogen, Phosphorus, Potassium, and Magnesium. When using store-bought fertilizers, you’ll need to use caution and calculation to not “burn” your plants from excessive amounts of salt that can cause discoloration and damage to the plant. Luckily, there are easy ways to create homemade, natural fertilizers by repurposing some of our everyday kitchen waste. 


Fast-growers like the Golden Pothos and Philodendron Brasil tend to show bigger leaves and longer vines when regularly treated with natural fertilizers, while the Fiddle Leaf Fig becomes fuller with regular treatment. Maintaining the soil’s nutrients during the growing season will also help plants grow stronger and healthier, building their resistance to stress and disease. Banana Water, Rice Water, and Eggshell Water are some of our favorite natural fertilizers and can be applied monthly while watering without the risk of over-fertilizing. 


You don’t need to be an experienced plant parent to begin incorporating it into your care routine. We’re here to make it simple and approachable. Follow the steps below to make Banana Water, Rice Water, or Eggshell Water fertilizer. We recommend using monthly when watering with water that has been left out overnight, free of harsh minerals. Also, note that recently potted plants should wait about two months to settle before treating with fertilizer. 



Banana Water

Great for adding Potassium, which builds its health, strength, and resistance to infection and infestation. 


Supplies:

  • A Jar With Lid 
  • 1-2 Ripe Banana Peels
  • Filtered, Distilled, or Spring Water

To Make:

  1. Place a ripe banana peel in a mason jar of water. 
  2. Seal and let it sit for about 2 days. 
  3. Add directly to the soil or your watering can

Banana Water is most effective when used right away and should not be stored.


Tip: You can also dehydrate your banana peels in the oven and add them directly into the soil, whole or crushed. 


Rice Water

Great for adding Nitrogen, Phosphorus, Potassium in addition to healthy bacteria. Brown Rice has more Magnesium, Potassium, and Phosphorus than white rice but any rice type would be beneficial.


Supplies:

  • A Jar With Lid 
  • Rice (Any Type, 1+ cups)
  • Filtered, Distilled, or Spring Water

To Make:

  1. Soak your dry rice in water for about 20-30 minutes 
  2. Feed rice water directly to your plants or into the watering can. 
  3. Store in a sealed jar or container at room temperature for up to 5 days. 

Tip: Rice Water is also great for use on hair and skin! The same steps and storage apply.


Eggshell Water

Great for adding Calcium, which builds healthy cells in the plant and reduces acidity in the soil. Most of the minerals are found in the shell's inner membrane. You can also grind eggshells into a fine powder to work directly into your soil by following these steps here


Supplies:

  • A Jar With Lid 
  • Eggshells (as many as you can collect at a time)
  • Filtered, Distilled, or Spring Water

To Make:

  1. Boil filtered water. 
  2. Rinse and lightly crush eggshells using a wooden utensil, mortar & pestle bowl, or blender.
  3. Place eggshells in a jar.
  4. Add boiling water.
  5. Let the water cool.
  6. Strain water/Remove eggshells.
  7. Feed directly into soil or watering can.

Tip: Nutrients come in small amounts in eggshells, so rinsing and collecting them in a bowl to dry throughout the month will allow you to make the most effective eggshell water.
