15 Best Fertilizer for Indoor Plants
The best fertilizer for indoor plants helps feed plants with all the necessary nutrients to grow and thrive. However, choosing the right product can be tricky with so many options available.
The right fertilizer for indoor plants should have a balance of minerals to ensure plants have lush foliage, healthy roots, and lovely flowers. They’re available in liquid, granular, and slow-release forms.
You can also find all-purpose plant foods. However, some indoor plants have specific nutrient needs, so you need to find one that has the right balance of macro-and micro-nutrients that they require.
This article includes a complete guide on fertilizers. I will discuss different types of fertilizers and review some of the most reliable fertilizers to help you pick the right one for your plants.
Is Fertilizer Necessary for Indoor Plants?
Indoor plants require frequent fertilizing to deliver nutrients for healthy growth and development. Thus, regular feeding supplies the potting soil with minerals that houseplants need.
It’s necessary to fertilize your plants because they don’t have a supply of organic matter, unlike outdoor plants. Adding fertilizer frequently ensures your indoor plants continue to thrive.
Keep in mind that fertilizer isn’t food. Most houseplants make their food by absorbing water and carbon dioxide. But they also need phosphorus, potassium, and nitrogen present in the soil.
Fertilizers deliver these nutrients to indoor plants. They get their food during photosynthesis when they get energy from light, water from the soil, and carbon dioxide from the air. These ingredients team up to deliver the necessary sugars that plants use for food, so they don’t need your help.
Of course, they need more than just food to develop properly. This is where fertilizers step in and make up for the phosphorus, nitrogen, and potassium that are lacking in potting soil.
What Kind of Fertilizer for Indoor Plants?
Fertilizers are available in sticks, liquids, granules, tablets, and slow-release forms. Plant enthusiasts say, slow-release and liquid fertilizers make a great choice for indoor plants.
Granules and sticks seem convenient. However, they don’t transfer nutrients very well via the soil. Once you’ve imported a fertilizer stick into your potting mix, you lose control over its function.
Granular fertilizers aren’t suitable for indoor plants because they’re created for outdoor use. All-purpose fertilizers, on the other hand, have the basic macronutrients that plants need to grow properly.
Specialty fertilizers have optimized shares of these nutrients for different types of plants. Opt for a high-quality fertilizer that also has micronutrients that will encourage healthier growth.
What Are the Best Fertilizers for Indoor Plants?
When shopping for the best fertilizers for indoor plants, a few brands stand out from the rest including Miracle-Gro and Jobe’s Organics. They’re known for their wide range of products and affordable prices. The following list highlights some of their best-selling fertilizers and key features.

Buying Guide: How to Choose Fertilizer for Indoor Plants?
While purchasing any fertilizer for indoor plants, always try to consider organic products first. They’re better sources of nutrients for indoor plants.
They’re also child-and pet-friendly sources of fertilization. Consider the following features when looking for fertilizers and make a well-informed purchase.
Macronutrients
Basic fertilizers include macronutrients such as phosphorus, nitrogen, and potassium. Each of them has a special task. For instance, nitrogen enhances lush foliage.
Phosphorus, on the other hand, improves root development and potassium promotes healthier blooms. Thus, opt for a fertilizer that contains these macronutrients.
Specialty fertilizer
Certain fertilizers have a special task as they’re designed for fertilizing certain types of plants. Therefore, consider the type of plants and determine if they need a specialty fertilizer.
Micronutrients
Micronutrients such as magnesium, iron, manganese, and boron are included in certain fertilizers. They encourage healthier development, so check the label before you buy.
How to Use Fertilizer for Indoor Plants?
Most plant lovers overlook the importance of fertilizing houseplants. However, regular fertilizing is very important. Fertilizers will help you grow healthy and lovely indoor plants.
Outdoor plants don’t require as much care and maintenance as indoor plants because nature delivers all the necessary nutrients. Thus, indoor plants are dependent on your care.
Finding the right potting mix is important and can supply nutrients for a while because modern fertilizers have enhancements mixed in. However, after about 2 months, the plants will have absorbed everything, so you will have to fertilize if you want a consistent, healthy development.
And since fertilizers come in different forms, they’re also applied differently. Therefore, always read the instructions. Too much fertilizer can destroy a plant, so follow the rules.
How to Make Fertilizer for Indoor Plants?
Using organic fertilizer for indoor plants is a great way to promote proper growth and flower production. Natural fertilizer can be just as effective as a harmful chemical fertilizer.
It can steadily release nutrients into the soil and doesn’t take long to make. The best part? It’s a safe and eco-friendly option. Maybe you don’t want to hear this but most fertilizers contain chemicals.
Organic fertilizers are commonly utilized in agriculture. Some of the most popular include kelp, compost tea, compost, cow or chicken manure, worm castings, alfalfa meal, limestone, and much more.
However, they’re not often utilized indoors due to the aroma. The only disadvantage (besides the smell) of organic fertilizers is the lack of knowledge of the N-P-K ratios. However, don’t stress about it.
Certain natural ingredients can meet the specific needs of your indoor plants. For instance, if your plants require nitrogen, include fish emulsion or alfalfa meal in your natural fertilizer for indoor plants.
If they lack phosphorus, apply rock phosphate or bone meal in your organic fertilizer for indoor plants. If they require extra potassium, a kelp meal or granite meal can help.
How to Use Fish Fertilizer for Indoor Plants?
Fish emulsion fertilizer is considered “natural” because it’s extracted from once-living beings.
Fish fertilizer or fish emulsion for indoor plants is a natural and fast-acting liquid fertilizer designed from the byproducts of the fishing industry. It’s abundant in potassium, phosphorus, and nitrogen.
It also contains trace elements such as magnesium, calcium, chlorine, sulfur, and sodium. Not only is fish fertilizer a natural solution, but it’s also made from fish parts that would be otherwise wasted.
The best part? It has a lot of nutrients for fast absorption by plants. Fish fertilizer for plants is a mild, all-purpose feeding solution that can be utilized whenever. It can be utilized as a foliar spray, soil drench, in the shape of a fish meal, or applied to the compost pile. It’s beneficial for leafy green vegetables.
They require nitrogen. And fish fertilizers are rich in nitrogen. Fish emulsion utilization is super beneficial as a lawn fertilizer in the early spring as well. However, be careful when utilizing fish fertilizer.
Too much fish fertilizer can damage plants and stop their growth. As long as you’re cautious, this type of fertilizer can be utilized at almost any growth level. It’s a concentrated product that’s water-soluble. Mix ½ ounces of fish emulsion with 1 gallon of water. Then, apply the mixture to your houseplants.
Experienced plant lovers suggest applying fish fertilizer twice per week to get the most benefit.
How to Make Liquid Fertilizer for Indoor Plants?
You can find a commercial liquid fertilizer for indoor plants wherever plant necessities are sold, but you can also make a natural liquid fertilizer for indoor plants with ingredients from your kitchen.
Homemade Liquid Fertilizer for Indoor Plants
Mix a teaspoon baking soda with a teaspoon Epsom salt, teaspoon saltpeter, and ½ teaspoon ammonia in a gallon of warm water. You can find these items at a drugstore or garden supply store.
Use a stick or spoon for mixing. Keep the homemade solution in a gallon-size container. Apply to indoor plants once a month by dissolving ¼ teaspoons of the mixture in a quart of water in a watering can.
Add a small amount of homemade plant food to houseplants as you finish your regular watering routine. Keep track of your plants’ progress. Signs of too much fertilizer include dropped or yellowish leaves.
In this case, water your plants thoroughly, enabling the excess water to drain off. This will remove all the damaging substances. Check out other homemade liquid plant foods you can easily prepare.
Homemade N-P-K Balanced Liquid Food
If your houseplants lack specific nutrients such as nitrogen, potassium, and phosphorus, you can prepare N-P-K balanced liquid food for indoor plants.
Pour water into a gallon container of milk that’s empty except for the residue. The amount of milk left in the solution has traces of potassium, nitrogen, and phosphorus.
You can do the same with apple or orange juice containers. Just pour water into the containers. The tiny amount of either of these acidic juices has trace amounts of potassium.
Water your houseplants utilizing a solution of water from the juice or milk containers, instead of utilizing tap water. It will provide a natural blend of the necessary nutrients.
Apply this liquid fertilizer every time you water your indoor plants. The traces of potassium, phosphorus, and nitrogen pose no danger of over-fertilization.
