11 Homemade and natural organic fertilizers

If you have a home garden or lands that you want to grow and improve the quality of the soil where you do it, it is advisable to use the healthiest and most natural fertilizers possible, especially if you want to grow your own food.

So naturally, and almost always cheap, we will be able to provide our plants with extra nutrients that will help them grow healthier and stronger.

The plants we grow require three types of basic nutrients such as calcium or magnesium, and nitrogen, potassium and phosphorus are of vital importance for the growth of all vegetables.


We show you here some of the natural, practical and economical organic fertilizers that provide all the necessary nutrients to our plants:


There are few organic fertilizers as good for enriching the soil in your garden as the simple and old decayed manure. You can buy bags of manure at most garden centers or, if you have chickens, goats or rabbits as pets in the backyard, you can also use your droppings.

Banana Skins:

Eating banana helps us replenish lost potassium, but it turns out that plants need it too. So when you finish eating this delicious fruit, simply throw the skins in a hole over your plantation, or bury them under the mulch to serve as a natural organic fertilizer.



Egg shells are a multipurpose aid in the garden, as they act as fertilizer, as a pest repellent. Add crushed egg shells at the bottom of your plantation holes, especially when they are tomatoes, peppers and eggplants.


Coffee grounds:

After enjoying a cup of coffee do not throw the grounds, as they are able to add a good amount of nitrogen to the soil. Contrary to popular belief, used coffee beans are not acidic and can act as a safe substitute for the nitrogen-rich fertilizer in your compost pile.


Human urine:

It sounds disgusting, but urine is considered sterile if the body it comes from is healthy. Urea has a high nitrogen content and contains more phosphorus and potassium than many of the fertilizers we buy at the store.


Rich in nitrogen, grass clippings become excellent organic fertilizers over time. Fill a 5 gallon bucket with grass clippings, or even weeds, as they absorb nutrients from the soil as much as grass. Then add water to the top of the bucket and let stand for a day or two.


Chimney Ash:

Organic chimney ash fertilizers are a great source of potassium and calcium carbonate and will replace your need for lime (if necessary). Do not use chimney ash around acidophilic plants or if the soil is alkaline. Place this ash on the garden soil and mix it with the soil.



The acetic acid present in vinegar works very well for plants that require an acid soil and can be used to replace fertilizers in indoor plants. Combine 1 tablespoon of white vinegar with 1 gallon of water and water the plants with the mixture. Repeat every three months.



Fresh seaweed does not need to be washed before use to remove salt, however in the Asian markets you can also find dried seaweed. Both fresh and dried versions are considered excellent organic fertilizers, since algae contain trace elements that serve as a natural food source for soil microbes.


Earthworm humus:

When earthworms feed, organic matter passes through their bodies and is excreted in the form of granulated dark pellets. You can see these little piles in the soil of your garden. A earthworm is able to produce its weight daily in humus, which is a wonderful fertilizer for plants.


By itself it does not contain so many nutritional elements, but it increases the humus content in the soil and significantly improves its physiological properties. In addition, the soil, abundantly dotted with peat, becomes light and "airy", and the roots of our plants feel very comfortable in such conditions. Peat can be collected in swamps and decomposed for ventilation, if you are going to fertilize the soil, or you can put it in a compost pile for decomposition if you want to use it as fertilizer. You can also find it in garden centers.

    Hola ¿Cómo estás? Los fertilizantes como cáscara de huevo, plátano o el césped tenía entendido que para hacerlos útiles a la tierra se tenía que hacer compostaje. ¿Vos los echás directamente a la tierra y ya sirve?
