How to Make Your Own Liquid Fertilizers

Liquid Fertilizer

Liquid Fertilizers are easy to make natural way to give your plants the vital nutrients they need for large growth, blooms, and produce.

You can make liquid fertilizer in a few easy steps. Store the mixture in a gallon container and label it with the ingredients.

Apply the mixture to houseplants, container gardens, raised garden beds, food gardens, and botanical gardens.

When making any fertilizer tea or diluting it, chlorine-free water should be used so the microbiome in the soil is not disturbed.



You can make your own comfrey liquid feed for your plants in the comfort of your home. You only need to soak comfrey leaves for 4 to 6 weeks and then store the liquid in a dark, cool place.

Then, add water to dilute it to the correct consistency with a 1 to 10 ratio of 1 part fertilizer to 10 parts of water, and use the mixture to fertilize your plants.

Comfrey tea should be covered as best as possible with the container in a spot that is not around your home because this stinky brew reeks when the decomposition process starts.

This deep-rooted and fast-growing plant produces a large amount of plant matter with leaves that are a good source of nitrogen, phosphorus, potassium as well as other nutrients.

It can be harvested 2 to 3 times during a growing season and if you have more than enough plant material to make the tea, then the rest of the plant material can be turned into the soil.

If you want to grow comfrey, choose a plant from the Bocking 14 variety which does not spread by seed. Plant it two to eight inches deep and you’re all set.

Comfrey can be grown in potting containers if you don’t have the extra room.


The leaves of the comfrey plant have hairs on the leaves that can irritate your skin.

Harvest can begin when the leaves are about one and a half feet long and only harvest the outer leaves unless winter is approaching.

This will keep the plant alive and growing for more harvesting later in the growing season.

Chopping the plant up makes the decomposition process faster but they can also be placed in a bucket or drum.

Fill the container to half full or three-quarters full with the plant material.

Make sure to press the plant material down firmly and if you like, you can place bricks or some large rocks to help compress the mass.

Depending on the amount of material will depend on whether a five-gallon bucket or a fifty-five-gallon drum that is preferably made of metal.

Fill the rest of the container with chlorine-free water and let it set for 3 to 6 weeks and ferment.

Keep a lid on the container at all times to prevent mosquitoes from invading the container and rainwater from diluting the mixture.



If you’re looking for a natural fertilizer for your garden then consider making your own alfalfa fertilizer tea.

Alfalfa is a good source of nitrogen, phosphorus, and potassium which are the three main nutrients for plant growth.

They also contain calcium, zinc, sulfur, iron, magnesium, and boron.

Their organic matter is great for feeding the microorganisms in the soil which in turn help them to make happy and healthy plants.


To prepare your own alfalfa tea just simply combine one pound of chopped alfalfa hay with five gallons of clean chlorine-free water.

Let the mixture sit for seven to ten days for maximum benefits but the longer you steep it, the stronger it is.

Alfalfa pellets can be soaked for 24 hours in a five-gallon bucket with 24 cups of pellets.

Alfalfa pellets have been shown to greatly reduce an infestation of nematodes, which are known to attack tomato plants and cyst nematodes which are known to attack carrots.

They are easy to add to the soil before tilling by just casting them out by hand.


One of the easiest ways to provide your garden with natural liquid fertilizer is to make tea with manure.

To make this using a five-gallon, fill it about three-quarters of the way with some manure and fill the rest with water and let sit for at least 24 hours.

Once steeped, the tea can be strained through a cheesecloth or paint strainer. The resulting mixture will be rich in nutrients and is ideal for a variety of garden plants.

The dilution ratio is 5 to 1 with the tea being 1 part fertilizer to 5 parts water.

The benefits of manure tea are multifaceted, it is best used on young seedlings and plants as it will boost their nitrogen content, which will promote healthy growth.

The manure used to make the tea can be reused in the compost pile or in the garden with a dilution ratio of one quart to one gallon of chlorine-free water.


These tiny creatures produce a lot of organic matter that can be used on your garden plants. You can simply apply the worm castings to the soil when you plant a new plant, or you can add them to the soil of your new raised bed.

You can also spread it around the base of established plants, like tomatoes and peppers.

In addition to providing essential plant nutrients, earthworm castings also improve the structure of the soil.

Worm bins can be purchased or built but make sure you use a container that allows them to breathe. Worms require a dark and warm environment to thrive.

Make sure that you place the bin in an area with good drainage. Ideally, you should use a shallow wooden box with drainage holes.

Worm castings work as an excellent liquid fertilizer because they are naturally pH neutral, which makes it easier for plants to absorb nutrients.

Worm castings also increase soil aeration, they are odorless, and they can also be used as a container plant fertilizer. If you have acidic soil, you can mix worm castings with natural organic fertilizer to get measured output.


Ammonia fixes nitrogen from the air into the soil and is used in about 80% of food production in the United States.

For best results, it is suggested to use one teaspoon of pure ammonia per one gallon of water and sprayed on the ground.

If you see signs of fertilizer burn such has the leaves turning brown then it is recommend to give the affected area a deep and slow watering. This will drive some extra nitrogen deeper in the soil.

Because plants need more then just nitrogen to grow, an ammonia fertilizer is best used after growing dikon radishes as a cover crop.

Before the radishes produce seed the field or garden is mowed and the soil is tilled.

As the radishes decompose in the soil they release phosphorus and photasium into the soil and this is when the ammonia should be applied.
