10 Best Natural Homemade Organic Fertilisers

by ThatWoW Editorial Team

When we talk about being organic, we want every part of the process to be natural. Back in the day, people wanted to grow veggies in their garden because they didn’t trust market products to be pure.

Of course, the extensive use of chemical fertilizers has decreased the purity levels and nutrition in veggies. We all want to reach the top purity level with our grown vegetables, at least.

But it won’t happen when you use the same artificial fertilizers from the market. Moreover, it can go even worse when your soil is weak. But you don’t want to resort to chemical fertilizers to replenish your land.

Don’t worry; you can use an array of things that are already available at home as organic fertilizers. The benefit isn’t just the purity of fertilizers, but you’ll save a lot of costs too.

Some of these recipes require waste material that you don’t use otherwise. One point you should note while reading these recipes is the nutrients each formula replenishes. Use the ones that fulfill your soil’s needs best.

10 Best Natural Homemade Organic Fertilisers

1. Epsom Salts

Epsom Salts or Hydrated magnesium sulfate replenish two essential nutrients in the soil. These salts are rich in Magnesium as well as sulfur in your soil. 

Magnesium boosts the enzymatic process as well as the food quality of your plants. It also helps seed generate quicker. Sulfur, on the other hand, offers benefits like the formation of chlorophyll, root growth, and amino acids.

With better food quality and enzymatic functioning, your cabbages, onions, and broccoli will taste sweeter than ever. You would also watch your tomatoes and peppers increase their blossoms by a notch. 

Moreover, Epsom salts are cheaper than most magnesium-rich fertilizers available. And all that without the side effects.

How to Use:

Pour a tablespoon of Epsom salt in a gallon of water. Mix well and apply every fortnight or so in your garden. 

You can also feed them to roses by mixing one tablespoon Epsom salt per feet height of the plant in a gallon of water. Use only sporadically for roses. Spray once when your leaves appear and again when the flowers start to bloom.

You can use it in the dry state for vegetables. Put a tablespoon on the newly planted seedlings, and you’re done. You hardly need anything else to make it work properly.

2. Compost Tea

Have one tea for yourself and one for your plants in the garden. The difference is that this compost tea will be significantly beneficial for their health, unlike your addictive regular tea.

Since compost has most of the soil of the nutrients, requires, you can use it both as manure and fertilizer.

How to Use: 

You need to have at least 2 gallons of compost. Fill it in a 5-gallon bucket and fill the rest of it with water. Now stir it regularly to make the mixture consistent. 

Leave it to soak for 3-4 days and pour it onto a porous microfiber cloth. Now mix once part tea with ten parts of water every time you use it in your garden. You can also use it as a spray or sprinkle it directly depending upon the requirement.

3. Eggshells

Eggshell is a pretty exciting yet useless item we dispose of every day. You might be doing it all wrong. There is one use of eggshells that would never let them go waste any more.

It is digene for the soil, an effective acidity regulator. It is one of those exclusive fertilizers for the plants who hate acidity. It’s also abundant in calcium, which is a useful trait. 

You can also use Lime as a natural fertilizer, but why even spend money when you can extract more out of eggs than omelets. 

How to Use it:

Store the eggshells and make an extensive collection to use in the garden. Crush them into fine particles, and you’re good to go.

You can either mix it with water or sprinkle it directly on your soil. It’s better to spray directly. You’d be surprised to know that eggshells contain 93% Calcium carbonate enough for your soil.

4. Grass Clipping Tea

If nitrogen is what your soil lacks, don’t go for those expensive fertilizers that fool you in the name of nitrogen. Try the excellent grass clipping tea fertilizer that has abundant amounts of nitrogen.

It’s a lesser-used material, but that doesn’t make it any less valid. It’s just about using different DIY fertilizers for different soils. It would also be one of the best uses of grass clippings you can think of.

How to Use:

This kind of tea is as easy, if not more comfortable, to make as your drinking tea. Just fill a five-gallon bucket with grass clippings up to 2/3rd.

Pour water and fill it right to the upper tip of the bucket. Let the mixture settle while stirring sporadically. Stirring once a day would be enough. 

Now use a filter to remove the residual grass, and you’re done. Keep the tea in a jar and dilute it with a similar amount of freshwater before use.

You can use it as a foliar spray as well as sprinkle it directly on the soil.

5. Fish Tank Water fertilizers

It can be pretty amazing to even think of such a fertilizer. The water from your fish tank finally has some use on this earth without the fish in it. And perhaps it directly affects you.

Used fish tank water is rich in nitrogen, which can be the best friend for your soil. You have to be careful in operating it, though. Any tiny dead fish might slip away from your eyes and die in the process.

Make sure that you have picked out the tiniest of fishes from it. Also, keep in mind that it’s not a seawater tank. Salty water can have converse effects on soil.

How to Use it:

Having taken all the above precautions, it’s time to apply the water on your soil. We have a surprise here, you though. Brace yourselves.

You have to do NOTHING in preparation. Cleaning up the tank of fishes is enough. Just put the water in a spray. Dirty untreated water is the best.

It’d be better if you don’t even filter it. Pour it directly on the soil to reap maximum benefits.

6. Dog Food Fertilizer

Are you running out of fertilizers and too lazy to go to the store? Borrow some from your canine friend. Yes, he has that.

Dog and even cat foods are excellent fertilizers. But it should only be organic dog food. Don’t feed supplements to your plants. 

It is rich in protein and micronutrients that are very nutritious for your plants. 

How to Use it:

It’s not an instant procedure; you’d need to give it a few days to decay. It works best when you put the mixture during soil preparation.

Spread the composted pet food along with water in the soil. Be cautious with animals, though. You might need to put cardboard to keep the food safe from your pet.

Also, apply a wet layer of mulch to protect it from weeds. Water the soil for the next three to four days. You should use pet foods containing more than 3% sodium of other chemicals, though.

7. Blackstrap Molasses

Many plants can grow in several harsh climates, but you won’t get the best out of them without proper care. Fertilizers do well to replenish these nutrients but come at a cost. And that cost is the soil quality and plant’s age at times.

Eliminate all these risks by using blackstrap molasses as fertilizers. This kind of molasses is rich in iron, sulfur, potash, carbon, potassium, copper, magnesium, and manganese. All in all, this would be a gift for your friends in the garden.

Moreover, molasses treat bacteria, which ensures the plants and soil remain healthy. The best part is that it is fit to use for any type of garden and plants.

How to Use it:

You’d need to mix blackstrap molasses with another all-purpose fertilizer. You can use a cup of alfalfa meal and Epsom salts to start. 

Add 4 cups of water to this mixture. Finally, top off the solution with a tablespoon of blackstrap molasses. If you’re using compost tea as fertilizer, you can add molasses to it too.

But ensure that your compost has already steeped or it would render the molasses ineffective.

8. Powdered Milk

If calcium is the need of the hour, it’s hard to find something other than milk. Be it a deficiency in your body or your plants; milk can come to rescue all the time.

That doesn’t mean you’ll pour some from your glass. Instead, you should use powdered milk as fertilizers to replenish calcium in your soil.

We don’t recommend to put fresh, usable milk there though. It would become quite expensive that way. Instead, put your old powdered milk cans to use by putting them into your soil.

How to Use it:

Open the pack, and start sprinkling. It’s as simple as that. You won’t need to dilute the milk at all. Sprinkle directly around the base of each plan as required.

You can also use it at the time of preparation for better, holistic growth. Sprinkle into the soil when you’re sowing the seeds for the best results.

9. Borax

While the ants in your soil might get nightmares of Borax, it’s quite beneficial for the land. But you should only use borax in measured quantities as we’ll discuss later.

You can check if your soil is boron deficient by looking for chlorosis, which is a symptom of boron deficiency. Here you might find yellow leaves and a vast number of brittle stems. Your best bet is to use your DIY cleaning agent borax than some fertilizer from the store.

How to Use it:

Large quantities of borax might have a counter-intuitive effect. Mix exactly one tablespoon borax in a gallon of water and stir well. Leave it aside for a few hours to settle down.

Now spray or pour on the base of your plants. Ideally, for medium-sized plants, pour an ounce of borax solution per plant. You can increase or decrease the amount as per your judgment. But never pour too much of it.

10. Seaweed Fertiliser

If you’re looking for something more rounded and professional, try seaweed fertilizer. People have used seaweeds fertilizers for hundreds of years. You can use both fresh and dried seaweed for this purpose.

Seaweed also contains Mannitol, which helps your plant absorb nutrients better. Ensure that you thoroughly wash your fresh or salted seaweed, or your soil might become salty.

How to Use it:

Chop seaweeds finely and put them in a 5-gallon bucket—mix 8 cups of seaweed with a half bucket of water for best results. Rainwater is perfect for this task, although freshwater would do.

Now let the seaweed soak water for two to three weeks. Cover the container loosely so that the plant can steep appropriately. Now strain the liquid and put the seaweed tea in another box. 

Whenever you want to use it, mix one-part water with one part seaweed tea. Pour it around the base of your plants and watch them energize and freshen up soon. You can store this tea for up to three weeks before it starts decaying.

These are a few to make fertilizers at home. For a better analysis of which you should use, check with your gardener for the nutrients your soil lacks. 

You won’t be able to use the right product unless you know what your is deficient in. So, get your soil checked in regular intervals or contact the expert when some of the plants have unusually stayed drying up or so.
