In today’s world it’s so easy to run to a store, purchase a gigantic jug of chemicals, and use it without batting an eye. There are certain times when you have to use a specific store-bought product but 99% of the time you can try a few natural things first. By creating your own natural houseplant fertilizer you’re not only saving money but also keeping harmful chemicals out of your home.

I use this DIY natural houseplant fertilizer every month or so. Whenever my houseplants start to look droopy or in need of a boost, I whip up a batch, and they quickly perk up within the next few days! I’ve used this on my kitchen herb garden, office plants, and even succulents.

DIY Project Inspiration

A year ago, my husband shared a video about a gardening expert’s passion for DIY fertilizers, including ingredients like bananas, tea, oat, and eggshells. This sparked my interest in making my own.

After a year of experimenting, I’ve created my homemade fertilizer, which I’m sharing here. I’ve carefully chosen effective ingredients, perfect proportions, and a simple process. That’s how this DIY fertilizer was born!

What is Natural Houseplant Fertilizer

Natural houseplant fertilizer is usually made of items you already have in your kitchen. They add nutrients into the soil without the use of chemicals. There’s tons of natural fertilizer ingredients: compost, coffee grounds, banana peels, tea, oats, and so many more!

Why This DIY Fertilizer Works

  • No ingredients sit on top of the soil to draw bugs and critters
  • Oats put nutrients back into the soil which improves the soil quality
  • Black tea has natural tannic acid and nitrogen present which helps grow healthy leaves
  • The mixture of oats and tea helps protect the plants from pests and diseases

Dangers of Commercial Houseplant Fertilizer

  • Inhalation Risk: There’s a potential danger when inhaling the chemicals present in these fertilizers, particularly when used indoors.
  • Accidental Ingestion: Swallowing these substances unintentionally can be hazardous to humans and pets.
  • Physical Contact: Skin contact with these chemicals should be avoided.

It’s important to be cautious when using any fertilizers indoors, as they can pose risks to both people and pets. Many commercial fertilizers contain nitrates, which are beneficial for plants but can be toxic to humans in high amounts. Always handle these products with care and follow safety instructions.

Frugal Side of Homemade Houseplant Fertilizer

Making your own houseplant fertilizer is easy on your wallet. By skipping the expensive fertilizers and making your own, you’ll spend pennies in comparison. Also you may already have black tea and oats in your kitchen!

Frequency of DIY Fertilizer Use

It really depends on your climate, location, and home air quality. For me, here in middle Tennessee, I use this fertilizer once a month in the winter season and every 2-3 months in the spring, summer, and fall seasons. It just depends how your plants look, feel, and act. When mine are droopy and water isn’t doing the trick, I’ll make a batch and it always helps perk them up.

Best Houseplant Fertilizer Ingredients

  • 6 cups water (boiling)
  • 1/2 cup rolled oats
  • 2 black tea bags/sachets
