How to Fertilize Tomatoes: [Utility, Date, Products and Homemade Ways]

Within the world of vegetables, tomatoes could be considered kings for their image, smell and taste.

But it must also be said that they are one of the most demanding plants out there because they need a lot of care and that is why learning how to fertilize tomatoes is key.

If you already have your plant ready to transplant or it is in the process of flowering and fruiting, write down what we bring you below.

This way you can have it well nourished and, therefore, with a lot of health to generate fruits in quality and quantity.

To deepen on tomato planting:

Why fertilize tomato plants?

The tomato plant needs to be fertilized above all to facilitate its good fixation to the ground at the time of transplanting.

It is for this reason that specialists in the area recommend that the fertilization be done successively in the first month and a half and then rest.

But in addition to regular fertilization, it is essential that the plant is placed in land that is already very well nourished.

Otherwise, it will be quite difficult for the tomato plant to prosper, much less generate fruit to harvest.

What does the tomato need?

For this plant to thrive properly, it needs to contain good levels of phosphorous, potassium, and nitrogen.

To do this, it is best to use balanced fertilizers, which are those that have the same levels of each of these components.

These fertilizers are commercially available, but at home we can also prepare high-quality versions without spending any money.

What are the main components of tomato fertilizer?

The main components that the fertilizer must have are the macronutrients: nitrogen, phosphorus and potassium.

These, in addition to providing the appropriate nutrition for the development of the plant, help to strengthen it against the presence of diseases.

Calcium is counted as another of the determining components to ensure that everything goes properly during cultivation.

In some commercially sold natural fertilizers this compound is included.


To make a top-quality homemade compost for your tomato plants, grind up banana peels (potassium), eggshells (calcium) and coffee leftovers.

What deficiencies can it have and how to detect them?

Observation and, later, laboratory tests will serve to detect if a tomato plant is deficient in nutrients.

Nitrogen deficiency

When plants are deficient in nitrogen, larger leaves will begin to look pale and droopy.

In the case of new or smaller leaves, they will remain undeveloped in terms of growth.

Phosphorus deficiency

When the deficiency is oriented to phosphorus, what occurs is that the leaves present purple colors and look weak.

potassium deficiency

In the case of low potassium, the yellow coloration will be present on the edge of the leaves, even affecting the fruits.

lack of calcium

By far, lack of calcium is the most complex problem because it can cause total fruit rot, leading to crop failure.

How to make a fertilizer compound for tomatoes step by step?

A fertilizer rich in phosphorus and potassium will be what the tomato plants will love and preparing it at home is quite easy and inexpensive.

  1. To make it, you will need as ingredients coffee remains (well or grounds), chicken manure and earthworm humus.
  2. In this case, the coffee will provide potassium, organic matter such as manure, phosphorus and humus, the microorganisms that will work on the decomposition.
  3. To prepare it, simply mix all the ingredients and place directly around the plant that needs it .
  4. In the case of tomatoes, one application before planting and another after the tomatoes begin to form will suffice for this cycle.

When this fertilizer is to be applied, it can be mixed with fertilized soil to maximize its action potential and enrichment of the plant.

Also use banana peel

Another way to make a good fertilizer is with banana peels, which will have to be cleaned and waited for them to disintegrate before adding to the soil. Unless you can crush them.

These also have a good potassium content and, instead of being left as waste, can be used to improve nutrition.

A similar case occurs with eggshells, which, although they decompose slowly, are useful to help the plant have access to the calcium it needs.

All these methods have an important particularity and that is that they are natural fertilizers.

Chemical fertilizers, perhaps not the best option

Although there are chemical versions that help achieve faster results, they can cause contamination in the fruit.

And, if so, they will become impossible for humans to consume, so it would be a total loss of crops.

Tomatoes need to be worked very carefully at all stages to ensure that their fruits are large, fresh and with a delicious interior.
