It’s easy to ignore fertilizer for your indoor plant once you feel you’ve checked other right boxes such as lighting, watering, temperature, humidity, soil, and a few more. But here’s where some indoor gardeners get it all wrong.

Indoor plant fertilizer gives the soil the nutrients plants need to grow well. Indoor plants can only get nutrients from the soil in the pot or container they are in. Unlike plants in a garden, which can send their roots out to look for food in the natural environment, indoor plants can only get nutrients from the soil in the pot or container and from any extra food you give them.

You could say that indoor plants can take care of themselves as long as they get enough light, water, and the right temperature, but over time, the soil loses its nutrients, especially because of watering. In this situation, indoor plant fertilizer gives your houseplants the nutrients they need to grow and thrive.

Houseplant fertilizer feeds your indoor plants by putting nutrients back into the potting soil. And you have to feed your houseplants at the right times for them to keep growing.

So, when should you fertilize your houseplants? How often should you apply fertilizer? What are the best fertilizers for your indoor plant, and which ones should you get? What should you watch out for when buying fertilizer for indoor plants?

We’ll answer these questions for you so you can give your indoor plants the micronutrients and macronutrients that will help them grow faster.

Why You Should Fertilize Your Indoor Plants

Some modern potting soils are already fortified with fertilizer and other nutrients, so a new one might not need them. But eventually, when the plant has used up all the nutrients in the soil, you will need to fertilize your indoor plants if you want them to keep growing.

Indoor plants don’t have access to natural organic matter, so they can’t get as much nutrition as they need. When the soil loses nutrients, you might want to repot the plant, but fertilizing is also helpful and easier.

Remember that your indoor plants don’t need fertilizers as much to grow. Your houseplants need the right place to grow and the right food. Photosynthesis is the process by which indoor plants get their food. This process uses energy from light, carbon dioxide from the air, and water from the soil. The only thing fertilizers do is add nutrients to the soil.

Indoor plant fertilizer has macro-nutrients like nitrogen (N), phosphorus (P), and potassium (K), and micro-nutrients like calcium, magnesium, sulfur, zinc, copper, boron, molybdenum, and chlorine. Each micronutrient is important for your indoor plant’s growth in its own way, but it doesn’t need as much of them as it does of the macronutrients.

When You Should Fertilize Your Indoor Plants

It’s not easy to figure out when the best time is to fertilize your indoor plants. If your indoor plants start to wilt, they need water, if their leaves are pale and long, they need light, and if the humidity is low, the leaves will be crispy and yellow. But how do you know if your indoor plants need fertilizer?

Slow or no growth might make you think you need fertilizers, but this could be caused by a number of things. So, we suggest that you fertilize your houseplants when they are growing and use indoor plant fertilizer according to the plant’s needs and growing cycle.

Also, you shouldn’t over-fertilize your indoor plant because it can burn the leaves and kill the plant in the long run. Most of the time, too much fertilizer is worse than not enough, and one way to avoid this mistake when caring for indoor plants is to follow the instructions on the package.

If you realize you’ve overfed your houseplant, you can bring it back to life by repotting or flushing the soil. For the soil flush, water is run through the soil for about 30 minutes, or until all of the extra fertilizer leaches out.

As a general rule, when you first start indoor gardening, you should fertilize your plant sparingly. After that, you can fertilize based on what your plant needs. Also, you should look for all-purpose fertilizers for your indoor plant because they are good for most houseplants.

Types of Indoor Plant Fertilizer

You now know why your indoor plants need fertilizer and when to fertilize, let’s consider the different types of fertilizers suitable for your indoor garden plants.

There are generally three types of indoor plant fertilizer: Liquid fertilizer, Granular fertilizer, and Slow Release Fertilizer. An addition is an organic fertilizer that can either be liquid, granular, or slow-release.

Liquid Indoor Plant Fertilizer: This is one of the best types of fertilizer for your indoor plant as it’s easy to apply and regulate. They are diluted into water and applied with a watering can when your houseplant needs feeding.

It’s easy to avoid over-fertilization with this type since it will be diluted with water. Liquid fertilizers also come with a reduced risk of fertilizer burn to your houseplant’s foliage. How often to use liquid fertilizer depends on the product’s instruction and the type of houseplant.

Indoor plants with large blooms require more feeding, but you should always study your houseplant’s requirements to understand their specific nutritional needs.

One disadvantage of liquid fertilizer is remembering to apply it every time as you’re likely to forget, especially during the cold season. Also, getting the right quantity to add can be tricky at times. As long as you can commit to a schedule and confirm the exact requirement for your houseplants, you wouldn’t have an issue with liquid fertilizer for your indoor plants.

Granular Indoor Plant Fertilizer: This type of indoor plant fertilizer is suitable when repotting a plant in fresh soil. The granules are either sprinkled on the surface of the soil or worked into the soil, and they release nutrients when you water your houseplant.

This type of fertilizer comes in either of these two formulations: loose, granular pellets or compressed fertilizer spikes. The granular pellets fertilizers are sprinkled on the surface of the soil, while the compressed fertilizer spikes are pushed down into the soil to come in close contact with plant roots.

Granular fertilizers are effective and affordable. Depending on the houseplants, you’ll need to reapply this type of indoor plant fertilizer after 4 to 6 weeks of the initial application.

One shortfall of granular fertilizer is that you cannot regulate the exact quantity required by your houseplants, which could lead to over-fertilization. As much as this houseplant fertilizer is effective, it’s not always a great choice to nourish your indoor garden plants.

Slow Release Indoor Plant Fertilizer: Slow-release fertilizer has become the favorite for most indoor gardeners. It comes in form of pods, spikes, pellets, and capsules and these time-release shells or coatings slowly release nutrients in smaller doses into the soil.

With this kind of indoor plant fertilizer, you wouldn’t have to fertilize as often because a single application can last for 4 to 9 months. It is easy to use and good for smaller pots or containers with houseplants.

Most slow-release fertilizers for indoor plants come in traditional forms that are not organic. Because of this, this type of fertilizer should only be used by experienced indoor gardeners who know what their plants need. If you can’t do that, liquid fertilizer is enough to feed your plants.

This indoor plant fertilizer is expensive, and it’s hard to control how much of each nutrient goes into the potting soil. The high price is made up for by how long it lasts, so you don’t have to buy it as often.

How to Choose the Best Fertilizer for Your Indoor Plants

Several things affect how you choose the best fertilizer for your indoor plant. You should think about whether the type of fertilizer, the amount of minerals, and the ratio are right for your houseplants and the type of soil they are in. You should also look into the easiest way to get the seeds to grow.

It can be hard to know what to look for in an indoor plant fertilizer, especially if you are new to indoor gardening, so that you can choose the best one to feed your houseplants. We’ll tell you about some of the most important things to think about when picking the best fertilizer for your indoor plants.

Plant Type and NPK Ratio

Every houseplant doesn’t have the same nutritional requirement and likewise, not all indoor plant fertilizers have the same mineral components and provide the same results.

In terms of mineral components in houseplant fertilizers, you want to refer to the macro and micronutrients that are essential for plant growth. The macronutrients are nitrogen (N), phosphorus (P), and potassium (K), and the micronutrients are calcium, magnesium, iron, boron, and zinc.

Each nutrient, be it macro or micro, has a specific function for houseplant growth. For the macronutrients:

• Nitrogen supports healthy foliage growth
• Phosphorous encourages bigger, healthier blooms
• Potassium encourages a strong room system

In choosing the best fertilizer for your indoor plant, you want to confirm the balance of the macronutrients, which is known as the NPK ratio. The NPK ratio states the percentage inclusion of the macronutrients. For instance, a 10-10-10 ratio implies 10 percent nitrogen, 10 percent phosphorus, and 10 percent potassium.

The higher the percentage of nutrients, the more potent the fertilizer is. There is, however, no perfect NPK ratio as each indoor plant’s requirement differs. For instance, flowering houseplants such as African violets, peace lilies, and begonias will need a higher amount of phosphorus than other nutrients. Green houseplants require fertilizer higher in nitrogen.

So, knowing your plant type fertilizer requirement is important in choosing the best indoor plant fertilizer to use. Also, you’d want to ensure that you’re getting a fertilizer specifically for indoor or houseplants with the NPK ratio written on the package.

Fertilization Method

Here, we’re referring to the mode of application and the ease of doing it. Knowing this is also helpful in choosing the best fertilizer for your indoor plant.

Liquid fertilizer is diluted with water according to the product’s instruction and sprayed on the leaves or surface of the soil; granular fertilizer is sprinkled on the soil surface or thrust into the soil root; slow-release fertilizer varies in the application based on the form it takes – either in pellets, capsules, pods or spikes.

In all, knowing the convenient fertilization method as it applies to your houseplant’s requirements can help choose the best indoor plant fertilizer.

Fertilizer Category

The two major fertilizer categories here are organic and traditional. This is an important factor an indoor gardener must take into consideration in choosing the best fertilizer for their indoor plant – organic or traditional?

Organic Fertilizer: They are made from natural components and free of harmful chemicals and synthetics that can affect indoor plant growth. Organic fertilizers usually come from plant waste, animal waste, or powdered minerals like bone meal.

One good thing about this type of indoor plant fertilizer is that it is environment friendly and it poses less risk of root burn for houseplants. It also helps to reduce the risk of excess minerals in the soil.

A downside of organic fertilizer is that, over time, the natural ingredients emit an unpleasant odor. Moreover, it’s advisable to go for organic fertilizers endorsed by the Organic Materials Review Institute (OMRI).

Traditional Fertilizer: This type of fertilizer is gotten from a mixture of minerals with the right proportion to feed indoor plants. Traditional fertilizers usually come in more concentrated formulas and are less costly than the organic type.

How to Develop DIY Homemade Natural Fertilizers for Indoor Plants

You can always purchase natural fertilizers for your indoor plants and they will provide the necessary nutrients your houseplant needs to thrive. Natural fertilizers at local stores can come either fast-acting liquids or slow-releasing dry formulations.

Ingredients in the fast-acting liquid include worm tea, kelp, compost tea, plant extracts, and fish emulsion. While the dry formulation is made of bone meal, blood meal, phosphate, limestone, and dehydrated worm casting.

You often won’t find the NPK ratio on commercial natural fertilizer since its components are complex. However, if you want to save money and fertilize your indoor plant with nutrients from natural substances, there are some household waste and items you can consider for this purpose.

Here are our top 9 DIY natural indoor plant fertilizer sources to save cost.

Eggshells: This is a good source of calcium, phosphorus, and other minerals helpful for indoor plant growth. Eggshells help to reduce acidity in the soil.

To use them as natural fertilizers, you’ll remove the inner layers, wash and allow them to dry. When dried you can crush them, let them steep overnight in boiled water and add the strained water to your potting soil. Alternatively, you can crush them and mix them into your soil when potting your indoor plants.

Banana Peels: They are rich in potassium with a little amount of nitrogen, phosphorus, and magnesium. Banana peels are good slow-release natural houseplant fertilizer and we can suggest a few ways to use them.

You can cut them into small pieces and mix them with potting soil while they decompose slowly and release the necessary nutrients into the soil for your houseplants to use. You can also blend the peels and mix them with water to become a natural liquid fertilizer for your indoor plants.

Aquarium Freshwater: Your freshwater aquarium is another source of natural fertilizers. The wastewater with decomposing fish food and waste is rich in natural nutrients that can be useful to your indoor plants.

So, when next you’re changing the water in your fish tank, add the wastewater to your houseplant’s soil. It contains nitrogen and potassium that your indoor plants need.

Molasses: This is a liquid substance gotten from refining sugar cane. It is composed of several nutrients beneficial for indoor plants. A tablespoon of molasses mixed with 2 liters of water is sufficient to nourish the potting soil for your indoor plants.

Cooked Vegetable Water: When you boil or steam your vegetables the water used is usually filled with nutrients that can help your indoor plants to grow. So, when you’re done cooking your vegetables, allow the water to cool and then give your potting soil to drink.

Worm Tea: By cultivating a worm farm on the side you can turn your kitchen scraps into natural houseplant fertilizers. This system works by placing food remnants or leftovers at the top of the worm farm and the worms will break them down into nutritional liquids to feed your houseplants

Epsom Salt: This contains micronutrients such as magnesium and sulfate that are helpful for houseplant growth. You can either sprinkle a small amount of Epsom salt on the surface of the soil or dilute a teaspoon into the water and spray it on the houseplants and soil.

Coffee Grounds: Used coffee grounds contain nitrogen, phosphorus, potassium, and magnesium that support healthy growth for indoor plants. It can be mixed with potting soil or derive liquid fertilizer by soaking them in water for some days.

Natural fertilizers from coffee grounds are beneficial to foliage plants and because they increase the acidity of the soil, you’d want to use them for houseplants that thrive on acidic soils such as African violets, jade plants, ferns, and cactus.

Green Tea: You don’t have to throw away your small green tea bags since you can use them to create an inexpensive homemade natural fertilizer. They are best used to fertilize acid-loving houseplants.

The leaves in the tea bags contain tannic acid that lowers the soil’s pH and its high nutrient concentration encourages indoor plants to grow faster. The liquid from the green tea can be used directly after it has cooled off or you can empty the tea bags and mix the leaves directly into the potting soil.

Bottom line

Fertilizing your indoor plants is not only beneficial to adding and replenishing the nutrients of your potting soil for healthy houseplants, but it also helps to improve the structure of the potting soil, increase aeration, and enhance its ability to hold moisture.

Now that you know why your indoor plants need fertilizers, it is advisable to use indoor plant fertilizers only when your houseplants are actively growing and flowering. The best time is actually during spring and summer.

More important, you need to know your indoor plants and their requirements. Are they heavy or light feeders? This helps you to choose the right fertilizer with a suitable NPK ratio. However, fertilize with caution because excess can harm your indoor plants.

And always bear in mind that “fertilizing when an indoor plant doesn’t need it is worse than not feeding it when it’s lacking nutrients.”
