Making natural fertilizer at home is easier than you think, and it's a great way to reduce waste and create a sustainable garden. You can start by collecting kitchen scraps like fruit and vegetable peels, eggshells, and coffee grounds.
These scraps are rich in nutrients like nitrogen, phosphorus, and potassium, which are essential for plant growth. For example, banana peels are high in potassium, which promotes healthy root development and fruiting.
Collecting garden scraps like leaves, grass clippings, and weeds is also a great idea. They're rich in nitrogen, which is a key nutrient for plant growth. By composting these scraps, you'll create a nutrient-rich fertilizer that's perfect for your garden.
To get started, gather a variety of kitchen and garden scraps and mix them together in a compost bin or pile.

Natural Fertilizer Sources
Tree leaves are a great source of natural fertilizer, similar to grass clippings. They can be laid directly over the soil like mulch and will break down into nutrients over time. Leaves are a great way to add organic matter to your soil.
Banana peels are another excellent natural fertilizer, rich in potassium. They can be chopped up and buried in the soil or combined with water to create a liquid fertilizer. This is especially beneficial for plants like tomatoes and roses.
Grass clippings are a simple and effective way to repurpose your lawn clippings into a natural fertilizer. They add nitrogen and potassium to the soil while also improving moisture retention. Just be sure to avoid using harsh chemical fertilizers on your lawn if you plan to repurpose the clippings.

Rice
Rice is a great source of natural fertilizer for your plants. It contains starch and small amounts of NPK, which are essential for plant health and growth.
The NPK in rice water is low in quantity, so you don't have to worry about over-fertilizing. This makes it a great option for building healthy soil while minimizing waste.
Washing rice before cooking it can actually help create a more effective fertilizer. The nutrients and starches that leach into the water can even take the place of NPK fertilizers.
A different take: Water Pillow
Make sure to cool the rice water completely before using it to water your plants. Adding salt to the water can harm your plants, so be sure to avoid that.
Use the rice water fresh, as it doesn't store well. This way, you can reap the benefits of this natural fertilizer without any hassle.

To use tree leaves as a fertilizer, simply rake them up and lay them over your soil like you would with mulch. This will allow the fungi to break down the leaves and turn them into nutrients for your plants.
Leaves are a great way to add potassium to your soil, which is essential for plant growth. They're also a slow-release fertilizer, meaning they'll provide nutrients to your plants over time.

Animal Manure
Animal manure is a natural fertilizer that's been used by our ancestors for centuries. It's a cost-effective option, as you're likely already paying for the cost of owning and feeding animals.
You can collect manure from various animals, including chickens, cows, turkeys, and rabbits. The manure from these animals has awesome benefits for your garden.
To use animal manure as a fertilizer, you'll need to dry and age it for about 6 months before adding it to your garden. This process helps kill any potential parasites and bacteria.
Don't use the waste from household pets or meat-eating animals, as it may contain harmful parasites and bacteria. Instead, stick to collecting manure from herbivores like cows, chickens, and rabbits.
Before applying animal manure to your entire garden, test it on a few plants first. This will help you determine which type of fertilizer works best for your specific soil, plants, and garden conditions.

Fill the jar about ⅓ - ½ of the way with clean water and add crushed food scraps like eggshells, coffee grounds, tea bags, or vegetable trimmings. Add more water as necessary, just make sure all the compost is covered.
To make compost tea, once you've almost filled the jar, top it up with water and shake once daily for a week. Let it sit away from direct sunlight, and don't put a tight-fitting lid on the jar.
You can also make homemade compost by adding food scraps or any organic waste to your compost pile. This will save you money on store-bought fertilizer.
The nutrients found in homemade compost are incredibly high in nitrogen, potassium, and other essential nutrients needed in your garden.

When to Use
When to Use Natural Fertilizer is a crucial decision for gardeners.
Apply natural fertilizer once in the spring to give your plants a seasonal boost. This timing allows the fertilizer to work effectively with the new growth of the season.
In outdoor settings where soil quality has previously been poor, a second application in the fall can help improve soil quality over time.
You should never apply food waste to a garden that's actively growing to minimize the risk of pathogen crossover.
Household Items as Fertilizers
Household items can be surprisingly effective as natural fertilizers. You can use aquarium water as a fertilizer, which is packed with nitrogen and perfect for leafy indoor houseplants.
Epsom salts, baking soda, and ammonia are another combination that can be used to make a natural fertilizer. Simply mix 1.5 tablespoons of Epsom salt, 1.5 teaspoons of baking soda, and a small amount of ammonia with water to create a fertilizer.
Coffee grounds are also a great option, as they're rich in nitrogen and potassium. You can add them to your compost, sprinkle them around your plants, or dilute them with water to make a liquid fertilizer.
Here are some household items you can use as fertilizers:
Eggshell
Eggshells are a great source of calcium and potassium, making them a valuable addition to your garden. They can be used to create a natural fertilizer that will help your plants grow strong and healthy.
To make eggshell fertilizer, start by collecting your eggshells and rinsing them thoroughly. Then, lay them out to dry in the sun, which will help kill off any bacteria that may be present. Once they're dry, you can crush them up and add them to your compost pile or sprinkle them around your seedlings as a natural pest control to deter slugs and snails.
You can also use eggshells to make a liquid fertilizer by steeping them in water. Simply add a handful of crushed eggshells to a jar of water and let it sit for 24 hours. Then, strain the mixture and use it to water your plants.
Here are some of the benefits of using eggshells as a fertilizer:
- Eggshells add calcium and potassium to the soil, which can help improve soil structure and fertility.
- They can be used to deter pests, such as slugs and snails, that can damage your plants.
- Eggshells can be added to compost piles to help speed up the decomposition process.
- They can be used to make a liquid fertilizer that can be applied to plants.
Some plants that benefit from eggshell fertilizer include lilacs, forsythia, clematis, broccoli, and Brussels sprouts.
Household Chemicals
Household chemicals can be surprisingly useful in the garden. Epsom salt, for example, contains high levels of magnesium and sulfur, which plants need to create healthy foliage and absorb nutrients from the soil.
Baking soda is another household chemical that's beneficial for plants. It helps plants bloom and protects them from fungal disease.
To make a natural fertilizer using these chemicals, mix 1.5 tablespoons of Epsom salt, 1.5 teaspoons of baking soda, and just under half a teaspoon of ammonia in an old 1-gallon plastic jug or watering can. Fill the rest of the container with water, shake well, and let it sit for 15 minutes to dissolve the ingredients.
This homemade fertilizer is a great solution for gardeners on a budget, as it uses inexpensive and common household products. You can find these ingredients at most grocery or superstores for just a few dollars.
