Which Houseplants Need Fertilizer?

Some houseplants need fertilizer, while others don’t. It’s important to know which plants in your home require it and which don’t, so you can give them the care they need for healthy growth. Generally speaking, flowering plants are more likely to benefit from fertilizer than foliage plants. If you’re not sure if your plant needs fertilizing, check with a local nursery or gardening store for advice.

For those that do require fertilizer, look for organic options made specifically for indoor houseplants to avoid any potential hazards. A slow-release formula is ideal since you won’t have to worry about overfeeding your plants or applying too much at once. Additionally, ensure any fertilizer you buy doesn’t contain hazardous chemicals or ingredients that could be toxic when ingested by pets and people.

Your houseplants may also need additional nutrients from time to time. If they start looking unhealthy or their growth slows down suddenly, consider adding some organic matter like composted manure or leaf mold into their soil mix periodically as an extra boost of nutrients. You could also try incorporating a few handfuls of worm castings into the soil around the roots of your plants every now and then—this natural option will provide helpful minerals without posing any safety risks.

Benefits of Homemade Fertilizer

Homemade fertilizer offers numerous benefits for your plants, providing essential nutrients they need to grow and thrive. Not only is it eco-friendly and cost-effective, but it also uses materials that you may already have in your kitchen or garden. By composting coffee grounds, eggshells, banana peels, worm tea, and other organic items with nitrogen-rich manure from animals such as horses, chickens, goats, and cattle, you can create a nutrient-rich fertilizer for your plants.

The natural ingredients used in homemade fertilizer are rich in the key nutrients of nitrogen, phosphorus, and potassium which plants need to survive and thrive. These substances provide the necessary fuel for plant growth while also conditioning the soil so that more water is retained. Additionally, using homemade fertilizer helps reduce waste since all those scraps would otherwise end up in landfills where they can release methane gas into the atmosphere.

Making your own fertilizer ensures that you know exactly what’s going into your plants’ food source—no hidden chemicals or preservatives here! You can rest assured that everything added to the mix is safe for both you and your plants because you get to choose which ingredients are used. Plus there’s no need to worry about overfeeding since fertilizers can be tailored specifically to each individual plant’s needs.

Creating your own homemade fertilizer isn’t complicated; with just a few easy steps and some basic tools, anyone can do it! So why not give it a try? Your plants will thank you!

How to Make Homemade Fertilizer

You can make your own homemade fertilizer for houseplants using a variety of natural ingredients. Fish emulsion, molasses, banana peels, coffee grounds and eggshells are all great options to consider. Each one provides its own unique benefits to your houseplant’s health, making them an ideal choice for anyone looking to provide their plants with the best care possible.

Fish Emulsion

Fish emulsion is an easy way to give your houseplants a natural boost of nutrients; it’s rich in nitrogen and other beneficial components, so applying it to diluted soil every two weeks can really make a difference. When you clean out the fish tank, save the aquarium water as it contains important nutrients that will benefit your plants. When preparing the fertilizer, mix the fish waste with water in a safe ratio for optimal results. Use protective gear such as gloves and goggles to avoid any skin or eye irritations. Fish emulsion is an effective fertilizer that will nourish your houseplants without causing harm to them or yourself.


Molasses is an excellent source of carbon for gardens and lawns, providing essential nutrients and minerals. It’s a great choice for fertilizing plants naturally:

  • It contains copper, magnesium, iron, calcium, and potassium.
  • Molasses provide food for beneficial soil microbes.
  • Mix it with Epsom salts or alfalfa meal to create a homemade fertilizer blend.
  • This mixture can help plants grow strong and healthy.
  • Follow safety instructions when using the fertilizer blend around your plants.

Banana Peels

Burying banana peels in the soil can give your plants a nutrient boost. They are rich in potassium, phosphorus, magnesium, and other essential nutrients that are beneficial to your plant’s growth. To use them as a fertilizer, bury the peels around the base of the plant or mix them with soil before planting. You can also make a liquid fertilizer by blending them with water. This is an easy and safe way to naturally feed your houseplants without having to buy any additional products. As long as you ensure that all parts of the peels have been buried underneath the surface of the soil, no pests will be attracted to it either!

Coffee Grounds

After discussing banana peels, let’s move on to coffee grounds. Coffee grounds are an excellent natural fertilizer that can be used for indoor plants. They contain nitrogen, potassium, and other essential nutrients that will slowly be released into the soil when sprinkled around the base of your plants. It’s best for acid-loving plants such as African violets, jade plants, Christmas cactus, peace lilies, and ferns since it makes the soil more acidic. To use this method safely fertilize your houseplants with coffee grounds in a way that won’t cause any harm to you or your plants.


You can add eggshells to your soil to give it a calcium boost. To get the most benefit, freeze them until you have a full carton’s worth and then either crush them with a rolling pin or grind them into a powder using a coffee grinder. Once you’ve got the pieces ready, mix them right into the soil when potting your plant or adding new soil to an existing houseplant. This will allow the plant to absorb their valuable nutrients. Adding eggshells is an easy and natural way to ensure your plants are getting all of the nourishment they need for healthy growth.

Epsom Salt

Mixing a tablespoon of Epsom salt into a gallon of water is an easy way to give your soil the magnesium and sulfur it needs. Not only is this natural fertilizer safe for your house plants, but it also offers many other benefits:

  • It helps strengthen the cell walls of plants making them more resilient
  • Aids in increasing nutrient uptake from the soil
  • Improves chlorophyll production and encourages lush foliage growth
  • Reduces stress caused by heat, drought, or over-fertilization
  • Enhances flowering and fruit production.

Epsom salt is simple to use, just mix one tablespoon with a gallon of water every two weeks and apply it directly to the soil around the plant base. You can even add some to existing potting mixes for extra nourishment. This natural fertilizer will help keep your house plants healthy while providing essential nutrients for strong growth.

Green Tea

Green tea can provide beneficial elements to improve soil quality and help your plants grow. It contains a variety of vitamins, amino acids, minerals, and antioxidants. The tannic acid in green tea can reduce the soil’s pH, which is ideal for plant growth. To fertilize house plants naturally with green tea, mix one bag of cooled green tea per two gallons of water and apply it to the soil every four weeks. Doing this will give your plants the nutrients they need to stay healthy and strong. Taking care when using any type of fertilizer is important for safety reasons; always follow instructions carefully before applying to your plants.


Using homemade fertilizer for houseplants offers a number of benefits. Not only is it a cost-effective way to ensure your plants are getting the nutrients they need, but it also helps you save time and energy in the long run. Plus, with just a few simple ingredients from around the house, you can create an all-natural fertilizer that’s better for your plants as well as the environment. To illustrate this point, think of homemade fertilizers like fresh produce from your garden – nourishing and full of life!
