How To Make Your Own Indoor Plant Fertilizer

Having your own house plants can be a great way to spruce up your home and add some color. But it’s important to make sure they’re getting the nutrients they need to thrive!

Making homemade plant fertilizer is a great way to provide your plants with the nutrients they need without having to buy an expensive store-bought fertilizer.

In this article, we’ll discuss how you can make your own indoor plant fertilizer. So let’s get started!

Gathering The Necessary Supplies

Making your own indoor plant fertilizer is easy and doesn’t require a lot of supplies. You’ll need to get some epsom salt, fish emulsion, liquid seaweed extract, and water. All these items can be found at most garden centers or online.

Epsom salt is made up of magnesium sulfate which helps your plants absorb nutrients better as well as making them stronger and healthier.

Fish emulsion is a great source of nitrogen and phosphorus while the liquid seaweed extract helps provide essential micronutrients that are often missing in soil.

Mixing these ingredients together will give you an all-natural fertilizer for your plants that won’t have any harsh chemicals or synthetic additives.

It’s easy to make and you’ll have everything you need to keep your plants thriving!

Composting For Nutrient-Rich Soil

Making your own indoor plant fertilizer can be easy and fun! Composting is an excellent way to create nutrient-rich soil for your houseplants. Here’s how to do it:

  1. Start with a container or bin that will fit in the space you have available. You’ll need enough room to add food scraps, leaves, and other organic materials.

  2. Add in things like vegetable and fruit scraps, coffee grounds, egg shells, shredded paper, grass clippings, leaves, and even manure from animals like rabbits or chickens.

  3. Give the compost a few weeks to break down and mix it periodically as it breaks down. This ensures that all of the items are evenly mixed together for optimal nutrition for your plants.

When the compost is ready, use it as a top layer on your potted plants or directly into outdoor beds for added nutrients!

Adding Organic Fertilizer To The Mix

Making your own indoor plant fertilizer is a great way to provide your plants with the nutrients they need. To make it extra effective, you can add organic fertilizer to the mix.

Organic fertilizers are derived from natural sources like animal manure and plant matter. They help to enrich the soil with essential nitrogen and other minerals that plants need to stay healthy and strong.

Adding organic fertilizer can also help keep pests away since it contains chemicals that are toxic to insects. When adding organic fertilizer, be sure to use the right amount for your specific plant.

Too much fertilizer can actually be harmful and prevent your plants from getting the nutrients they need. It’s also important to give your plants enough water after adding the fertilizer so that it has time to soak in and start working its magic!

Making Natural Liquid Fertilizer

Now that you have added organic fertilizer to your soil mix, let’s move on to making a natural liquid fertilizer for your indoor plants.

This type of fertilizer is very easy to make, and it can be used to supplement the nutrients in your soil or as a stand-alone fertilizer.

To make this fertilizer, you’ll need some compost, water and a few other materials.

Start by placing one cup of compost into a bucket or jar. Then fill the container with enough water so that the compost is just covered.

Let this sit for at least 24 hours before straining out the solids from the liquid with a cheesecloth or fine sieve.

Once you have strained out the solid pieces, you now have a concentrated liquid fertilizer that can be used on all types of indoor plants.

Preparing Homemade Granular Fertilizers

Making your own indoor plant fertilizer is a great way to give your plants the nutrients they need to stay healthy and green. It’s easy to prepare granular fertilizers at home with simple ingredients like fish emulsion, kelp meal, and coffee grounds.

To prepare homemade granular fertilizer, start by mixing together three tablespoons of fish emulsion and two tablespoons of kelp meal in a large bowl. Then add one tablespoon of ground coffee and mix everything together until it forms a thick paste.

Finally, spread the mixture evenly over the soil in your indoor plants’ pots.

Make sure to water your plants after applying the fertilizer to help them absorb its nutrients. You should also apply fertilizer every few weeks or as needed for better results.

Here’s how you can make your own fertilizer to use on your indoor plants.

The first step in making fertilizer is gathering the materials you’ll need. This includes compost, peat moss, alfalfa meal, bone meal, kelp meal, earthworm castings, and plant-based compost tea. Once you have these materials you can begin mixing them together in a bucket. Start by adding two parts of compost to one part each of all the other ingredients. Then stir everything together until it’s blended evenly.

Maintaining Optimal Soil Nutrition For Your Plants

It’s essential to ensure that your plants are receiving the vital nutrients they need to grow and thrive. Luckily, there are a few easy ways you can make your own plant fertilizer at home.

To maintain optimal soil nutrition for your plants, you’ll need to:

  • Provide them with necessary nutrients:

  • Use compost or manure to return organic matter back into the soil, as well as help it retain moisture and nutrients.

  • Consider adding Epsom salts or rock dust to provide magnesium and additional minerals.

  • Monitor soil pH levels:

  • Purchase a soil test kit from your local home and garden store.

  • Test the soil pH regularly, and then use lime (to increase pH) or sulfur (to decrease pH) as needed.

Finally, remember to water your plants properly. Too much or too little water can cause nutrient deficiencies in the soil, so be sure you’re providing enough water – but not too much – for healthy growth!


In conclusion, making your own indoor plant fertilizer can be a rewarding experience. It’s not as hard as you may think and it’s really fun to do. Plus, it’s usually cheaper than buying pre-made products from the store.

All you need are some basic supplies and a little bit of knowledge about composting and soil nutrition. With just a few steps you can make your own nutrient-rich soil that will keep your plants healthy and happy for years to come!

So don’t be afraid to give it a try – you won’t regret it!
