Fertilizer is often thought of as something that is only needed for outdoor plants. However, indoor plants can also benefit from fertilization. Indoor plants are typically grown in pots, which can restrict their access to nutrients.
Therefore it’s important to give them an extra boost with fertilizer. There are many different types of fertilizer that you can buy from a garden center or nursery.
However, it’s also easy to make your own fertilizer at home. Fertilizer is one of the most important things you can give your plants to ensure they are healthy and thrive.
Homemade fertilizer is not only cheaper, but it’s also often more effective than commercial fertilizer. Homemade fertilizer is easy to make and a great way to recycle some of the household waste that would otherwise end up in the trash. Plus, it is much gentler on your plants than chemical fertilizers.
This article will show you how to make homemade fertilizer for indoor plants. We will also share some tips on how to use & benefit from it.
What Plants Need Fertilizer and Why?
Fertilizer is an essential part of gardening and landscape maintenance. Plants need fertilizer to give them the nutrients they need to grow and thrive. Without fertilizer, plants can become stressed, unhealthy, and even die. Here is the guide about plant food vs plant fertilizer if you are confuse between these.
So, what plants need fertilizer and why?
Most plants need fertilizer to give them the necessary nutrients for healthy growth. Fertilizers are a combination of nitrogen, phosphorus, and potassium. These three elements are essential for plant growth and development.
Nitrogen helps plants produce strong stems and leaves, phosphorus helps with root development and flowering, and potassium helps with fruit and seed production.
Nitrogen is especially important for plants as it helps them create proteins and other building blocks that are necessary for healthy leaves, stems, and flowers.
Without enough nitrogen, plants will struggle to perform photosynthesis properly, resulting in unhealthy and weak leaves. In addition to the three main elements, most fertilizers contain trace elements such as zinc, iron, manganese, and boron.
These trace elements are also essential for healthy plant growth, as they help uptake other essential elements. When and how often you fertilize also depends on the type of plant you’re growing.
Annual plants, such as vegetables, flowers, and herbs, should be fertilized every few weeks during their active growing season. Organic fertilizers are a great option for maintaining a healthy and sustainable garden.
Organic fertilizers are derived from natural sources and often contain a mix of beneficial microorganisms, which help to break down organic matter into readily available nutrients for plants.
No matter what type of plants you’re growing, fertilizer is essential for healthy growth and development. The type and amount of fertilizer you use should be tailored to the specific needs of your plants.

One of the most important aspects of houseplant care is providing them with the proper nutrients. While several commercial plant fertilizers are available, a variety of natural alternatives can also be used to help nourish your houseplants.

Bury the peels in the soil around the base of your plants, and the nutrients will eventually make their way into the soil. You can also mix the peels with soil before planting or make a liquid fertilizer for your plants by blending them with water.
- Coffee Grounds: Coffee grounds are filled with nitrogen, potassium, and other essential nutrients, making them a great natural fertilizer for indoor plants.

It would be best if you used coffee grounds on acid-loving plants like African violets, jade plants, Christmas cactus, and ferns to make the soil more acidic.
- Eggshells: Eggshells are filled with calcium, which is essential for healthy plant growth. You can save eggshells as fertilizer for houseplants by freezing them until you have a whole carton.
Simply crush the shells with a rolling pin inside their freezer bag or use a coffee grinder to make shell powder.
When you pot your plant or enhance the soil surface of an existing plant, you can mix some eggshells right into the soil. It is then possible for the soil to absorb the nutrients that they release.
- Epsom Salt: Epsom salt is a great source of magnesium and sulfur, which are both essential for healthy plant growth. Mix a tablespoon of Epsom salt into a gallon of water and use it to water your plants.

In green tea leaves, tannic acid is present, which helps lower the soil's pH, which is beneficial for growing plants. When used as a fertilizer, green tea can help to reduce soil compaction and make it more nutrient-rich, creating an ideal environment for plants to thrive.

Additionally, it promotes nutrient storage and moisture retention in the soil, which would otherwise be poured down the drain.
It is important for plants to have many essential micronutrients in their water, which are released when foods like pasta, vegetables, or eggs are boiled.
Calcium, phosphorus, and nitrogen are included in this category; Plants love these nutrients.
Allow the water to cool down after cooking, and use it to water your houseplants.
