10 Natural Fertilizers to Keep Your Houseplants Thriving

Indoor plants bring life and beauty to our homes, but they need proper care to stay healthy and vibrant. One crucial aspect of plant care is providing them with the right nutrients. While there are many commercial fertilizers available, natural alternatives can be just as effective. In fact, you may already have some of these natural fertilizers in your home!

1. Banana Peels

Don’t toss those banana peels in the trash just yet! They are an excellent source of potassium, as well as small amounts of nitrogen, phosphorus, and magnesium. You can simply lay the peel directly on the soil or cut it into small pieces and mix it into the soil. Another option is to blend the peels with water to create a nutritious liquid fertilizer.

2. Eggshells

Eggshells are not only a great source of calcium but also help reduce soil acidity. Crushed eggshells can be mixed into the soil or soaked in water overnight to create a mineral-rich liquid for your plants.

3. Worm Tea

If you have a worm farm or indoor compost bin, you’re in luck! Worms break down kitchen scraps and produce a nutrient-rich liquid tea that your plants will love. Alternatively, you can consider using a Bokashi system to create a diluted liquid fertilizer for your indoor plants.

4. Cooking Water

When you boil or steam vegetables, the water becomes infused with essential nutrients. Instead of pouring it down the drain, let it cool and use it to hydrate your houseplants. This way, you’ll be recycling nutrients and giving your plants a healthy drink!

5. Coffee Grounds

Coffee grounds can be a fantastic fertilizer for your indoor plants. Mix them with potting soil before planting or combine them with water to create a liquid fertilizer. Keep in mind that coffee grounds make the soil more acidic, so they are best suited for plants that thrive in acidic conditions.

6. Green Tea

For green tea drinkers, don’t throw away those used tea bags just yet! Empty the tea leaves onto the soil or brew them in water to create a nutritious liquid fertilizer. Green tea is best for plants that prefer acidic soil.

7. Epsom Salt

Epsom salt contains magnesium and sulfate, which are essential for plant health. Dissolve a teaspoon of Epsom salt in a liter of water or sprinkle a small amount on the soil surface to provide your houseplants with these valuable minerals.

8. Fish Tank Water

Do you own a freshwater aquarium? When you clean it, save the water! The water from aquariums contains nitrogen and potassium from fish waste, making it an excellent natural fertilizer for your plants.

9. Hair

Believe it or not, hair can be a valuable source of nutrients for your houseplants. Whether it’s your own hair, pet hair, or even hair from a hairbrush, mix a small handful into the soil before potting your plants. As the hair decomposes, it releases nitrogen and magnesium, aiding in plant growth.

10. Molasses

Molasses, a thick black liquid derived from refining sugar cane, contains a wide range of nutrients that benefit houseplants. Mix one tablespoon of molasses with half a gallon of water, and your plants will have a nutritious drink.
