How To Make Fertilizer For Houseplants

Magnesium and sulfate, which are included in epsom salt, support the health and growth of houseplants.

A teaspoon of epsom salts can be dissolved in a litre (approximately a quart) of water to create a simple natural plant fertilizer, or a tiny amount can be sprinkled on the soil’s surface.

How can homemade plant fertilizer for indoor plants be made?

In a fresh gallon jug, add 1 1/2 tablespoons of Epsom salt. This DIY plant food can be stored in a cleaned-out plastic milk jug with lid.


A tiny 1/2 teaspoon of household ammonia should be added to the jug. Scant refers to a small fraction of a teaspoon. Avoid using too much ammonia; a little bit goes a long way!


To enable the Epsom salt to completely dissolve, allow to sit for at least 30 minutes. Label the container and keep it out of the reach of children and pets in a cold, dry place.

Which organic fertilizer is best for indoor plants?

Fertilizing indoor plants will enable them to flourish and maintain their beautiful appearance all year long. Natural fertilizers for indoor plants are a fantastic choice because they are risk-free, efficient, and offer a consistent delivery of nutrients into the soil. They are also environmentally friendly and will eventually raise the caliber of the potting soil.

How can you naturally fertilize houseplants? You can utilize natural organic material to offer nutrients for organic fertilization of your indoor plants. Homemade waste materials like coffee grounds, egg shells, banana peels, and green tea leaves work well, as does commercially available natural houseplant fertilizer.

Seaweed Tea

Don’t be put off by the name; even if you don’t live by the sea, you can still produce this fertilizer.

  • Gather any “marine weeds” (including freshwater seaweed) you can find nearby.
  • Verify your local or state laws to see if collecting seaweed is legal where you live. There can be various laws in your area depending on protected lands and animals.
  • Check for washed-up seaweed on the shore by taking a stroll along the edge of a nearby lake, pond, or body of water.
  • Rinse the seaweed to get rid of any salt, pests, or debris (if you have an ocean nearby).
  • Chop the seaweed, then place it in a bucket with enough water to cover it and steep it for a few weeks.
  • The majority of the nutrients are absorbed by the water as the seaweed decomposes. Remove the seaweed after 3 to 4 weeks of steeping, then use the tea for your plants after combining it with 50% ordinary water.

Epsom Salts, Baking Powder, and Ammonia

You may create a natural fertilizer that provides your plants with all the nutrients they require by combining a few affordable and everyday items. And if you’re looking for an off-grid way to save money, this is a terrific idea to try.

Magnesium and sulfur, which plants require to produce wholesome foliage and absorb nutrients from the soil, are abundant in epsom salt.

Ammonia includes nitrogen to help with the growth of a healthy root system, while baking soda promotes flowering and guards plants against fungal disease.

You probably already have these three readily available materials in your homestead kitchen or elsewhere in the house, and they conveniently contain the majority of the nutrients required to develop a healthy plant. If not, most supermarket stores and superstores carry them for a few dollars.

Here is a fast recipe for DIY fertilizer made with Epsom salts, baking soda, and ammonia.

  • Mix the natural fertilizer in an old 1-gallon plastic jug or watering can.
  • 1.5 tablespoons Epsom salt, 1.5 teaspoons baking soda, and less than 0.5 teaspoon ammonia should all be added.
  • Fill the remaining space in your empty jug with water once you’ve added these.
  • Shake vigorously to combine. 15 minutes should pass for the components to dissolve.
  • Apply to indoor plants or your vegetable garden.

Banana Peels

It turns out that plants require potassium for growth in the same amounts as humans do. If your family is anything like ours, you probably consume a good number of bananas each week.

If you don’t already compost, save your banana peels and place them near to plants like rose bushes or others that need a lot of potassium. Bury the peels in a hole a few inches below the surface. If you don’t feel like preparing banana bread, you can even do this with overripe bananas!

If you want to go a step further, steep the bananas in water much like you would for making seaweed tea. Use the water AND the peels to apply some natural fertilizer to your garden once the mixture has steeped for a sufficient amount of time.

Animal Manure

Animal manure is the original and best natural fertilizer on the market. Since humans first started farming, our predecessors have used animal dung as a homemade (or animal-made) plant nourishment.

Except for the expense of owning and feeding animals, it is plainly free. But since people don’t keep animals only to generate compost, you would still have to pay for those expenses.

Their manure will be fantastic for your garden whether you have chickens, cows, turkeys, rabbits, or other homesteading livestock.

Remember that before using the manure in your garden, it needs to be aged and dried for around six months. Additionally, avoid using pet or meat-eating animal feces because it could be contaminated with dangerous bacteria and parasites.

Aquarium Water

Save the water from cleaning your aquarium or fishbowl so you can use it in your garden. As you are aware, over time fish excrement causes aquarium water to become unclean, stinky, and hazy.

The same waste that makes aquarium water so beneficial for your plants by supplying soil with natural fertilizer and nutrients. Another essential ingredient for thriving plants, nitrogen, is present in high concentrations in the aquarium water.

Test any of these fertilizers on a few plants before using them throughout your entire garden. Different forms of fertilizer will work better on different soils, plants, and gardens because they all have unique requirements and inadequacies. You can determine which of your own plant foods works best for you by experimenting with them first.

Compost Tea

Compost tea is classified separately from conventional compost because it can be used on its own and provides apartment dwellers with a simple alternative if you’re short on room. Here is a recipe for compost tea.

  • Keep a glass jar on your counter, or store it in a cabinet or closet.
  • About a third to a half of the jar should be filled with fresh water.
  • Eggshells, coffee grounds, tea bags, or vegetable trimmings are all examples of food leftovers that can be crushed up and put in the jar.
  • Make sure the compost is completely submerged before adding additional water as needed.
  • When the jar is nearly full, top it off with water and shake it once every day for a week.
  • Put a loose-fitting lid on the jar and allow it to sit out of the direct sun. If fermentation happens and you forget about it, you don’t want it to accidentally explode. If you notice the liquid starting to ferment, put it in your garden right away to stop further fermentation.

Homemade Compost

This one may sound obvious, but you’d be astonished at how few people really compost.

Extremely high levels of nitrogen, potassium, and other crucial nutrients are present in organic matter, which is what your garden needs. Save these nutrients instead of discarding them. Add food scraps and other organic waste to your compost pile whenever you have them.

Why would you pay for something you already have at home when the nutrients in pricey store-bought fertilizer will be comparable to (if not lower than) the amounts of nutrients in your own compost?

Which natural fertilizer works the best?

Jeff Holman lists the chemical-free organic fertilizers that are ideal for an organic kitchen garden and will leave your plants blossoming gorgeously.

Chemical fertilizers with high concentrations of nitrogen, potash, and phosphorus—the three essential nutrients that plants require to grow—have been recommended to gardeners for years. However, many chemical fertilizers, according to Ben Raskin of the Soil Association, contain more than quadruple the quantity of nutrients that your fruit and vegetables actually require. Raskin explains that this is an issue since the extra minerals end up in water sources that are utilized by both people and animals after being washed away by rain and irrigation. This poses a serious pollution danger. Given the abundance of environmentally acceptable alternatives, most of us don’t require turbo-charged chemical fertilizers because, unlike farmers, we aren’t growing food for sale. Here are the top five.

Kelp Potassium and a little amount of nitrogen are present in kelp-based fertilizers, but their main advantages are the long-term effects they can have on your plants. It has been demonstrated that kelp encourages soil growth, which helps plants flourish and boosts overall production. Additionally, it enables plants and crops to adapt more readily to temperature extremes like ice and extended periods of sunlight. Although you can purchase kelp at garden centers, gathering and composting it yourself is the most affordable method to acquire some.

cow feces Cow manure, the most popular kind of muck, is nutrient-rich and feeds both soil and plants. Applying fresh manure directly to plants, as with chicken manure, might cause them to burn, therefore you must properly compost it before using. If you’re applying it on fruits and vegetables, it’s worth looking for cow manure that has been raised organically; otherwise, you run the risk of giving your plants, among other things, chemical antibiotic residues.

adobe meal Although it does contain a fair quantity of nitrogen as well as some potassium and phosphorus, alfalfa meal is another plant-based fertilizer that benefits the garden in subtle ways. The true advantage of alfalfa is that it enhances soil quality and makes it possible to produce more nutrients for plants to consume, which eventually leads to an increase in plant development. Most garden centers sell it, and it works very well on roses.

Limestone Generally speaking, limestone fertilizer is a good addition to soil, however the advantages vary depending on where the stone came from. Limestone provides calcium, which aids in general plant growth, and magnesium, which promotes stronger, healthier plants. Limestone is used to adjust PH levels in soils with high acidity. Before applying limestone fertilizers, it’s crucial to analyze the soil’s acidity levels to establish how much, if any, is required. chicken poop More nitrogen, potassium, and phosphorus are found in chicken poop than any other sort of manure, and calcium and magnesium are also abundant in it. You can purchase the manure as pellets or ask a neighboring farmer for leftover chicken muck to compost yourself. The high nitrogen content of fresh manure can burn plants, so you must make sure it has been adequately composted before using it. In order to keep the organic and nutritional value of your fertiliser, as Raskin emphasizes, make sure it comes from a free-range chicken farm.

REVIEW Freely Grow Your Own Food According to Andy McKee, Dave Hamilton’s book is filled with helpful tips and includes everything you need to get started living a more independent lifestyle.

Are eggshells beneficial for houseplants?

You are not required to fertilize your plants using commercial fertilizer. To naturally add more calcium to the soil or soil surface of your indoor plants, simply add crushed eggshells.

The eggshells will also assist to aerate the soil, which is another benefit. The roots of your plants might develop more easily as a result.

Clean eggshells should be ground into a fine powder in a food processor, coffee grinder, or mortar and pestle to generate your own organic plant fertilizer.

When you repot your plant, mix this eggshell powder into the soil and add it to the soil around the base of the plant.

Make Epsom Salt Fertilizer

Dissolve 1 gallon of water and 1 spoonful of Epsom salt. Shake the mixture vigorously. Plants should be watered with the solution. During the growing season, give them a monthly drink of this mixture.

It functions as intended because Epsom salt contains both the essential plant nutrients sulfate and magnesium. Try it on some of the plants that love magnesium, such as houseplants, roses, peppers, tomatoes, and potatoes. A little fertilizer goes a long way, just like any other! Use the appropriate dosage for the size of the plant.

Try Coffee Ground Fertilizer

Using newspaper, cover a cookie sheet. Your used coffee grinds should be spread out on the sheet to dry fully. Your acid-loving plants’ bases should be covered in the leftover grounds.

This works because coffee grounds are abundant in potassium, nitrogen, and magnesium, all vital plant nutrients. They can help you increase the acidity of the soil because they are naturally acidic. Blueberries, rhododendrons, roses, and azaleas are just a few of the plants that will profit from this process.

Use Eggshells as Fertilizer

Keep the eggshells and let them air dry. The dried shells should be processed in a blender until powdery-fine. Around the plants in your garden, sprinkle the shell powder.

This works well because calcium carbonate, the primary component of agricultural lime, makes up almost all of eggshells. In the garden, use this in place of lime.

Create Vinegar Fertilizer

1 tablespoon of white vinegar and water should be combined. Plants should be watered with the solution. Every three months, repeat.

This works because vinegar’s acetic acid increases the soil’s acidity, which is perfect for acid-loving plants. Use this in place of soil acidifiers, rose food, and indoor plant fertilizer.

Never fertilize your plants with pure vinegar. Vinegar straight up acts as a herbicide.

Use Fish Tank Water

The next time you clean your fish tank, simply preserve the water. When watering any plants, use it liberally and frequently.

This works because the water from used fish tanks is rich in nitrogen and other nutrients that are essential for plant growth. You can use this in place of any other fertilizer type.

Employ Fireplace Ashes

After they have cooled, gather the fireplace ashes. Your garden beds should be covered with cool (never hot) fireplace ash, which you should mix into the soil.

Calcium carbonate and potassium are abundant in fireplace ash. It will assist in bringing your soil’s pH into equilibrium if it is too acidic, making it easier for your plants to absorb the nutrients in the soil. Replace garden lime with it.

You shouldn’t utilize fireplace ash if your soil is alkaline. Aside from that, it shouldn’t be applied to acid-loving plants unless you want to make hydrangeas pink.

Make Your Own Compost

Keep your newspaper, grass clippings, fruit and vegetable leftovers, and other compostable things. Start a compost bin or pile with them. Turn your pile and periodically add a little water to hasten the composting process.

It’s time to spread the dirt in your garden once everything has decomposed into a rich, dark soil.

Compost is a rich source of nutrients and beneficial microbes for your garden. It is an excellent organic soil improver that may be applied anyplace in the garden.
