Best Tomato Fertilizer 2018

In the world of tomato -and crop- production, your harvest is only as good as the fertilizer you use to enrich and amend the soil. A fertilizer is basically a product, which can be natural or synthetic, and that is used to supply minerals and nutrients to the soil, and therefore the crops planted there.

Most -if not all- fertilizers work in two specific areas. First, as I mentioned above, to supply the plant with the nutrients that are essential to its growth. And second, to amend the soil by improving both its water retention capabilities and aeration. Both of these areas are essential to the successful development of any given plant.

Important Nutrients For Tomato Growth

Tomato -and all vegetable plants, for that matter- have different nutrient requirements at their various development stages. In order to produce healthy plants, that yield big and juicy crops, they need to be supplied with nitrogen, potassium, phosphorus, iron, calcium, magnesium, cadmium, and many other types of trace minerals.

The most important by far are nitrogen, potassium, and phosphorus, for several reasons:

  • Nitrogen will encourage leaf growth. This makes it a very important element for growing grass and lawn plants, but no so much for growing crops, as excessive leaf growth can and will interfere with blossom and fruit production.
  • Phosphorus will improve blossoming and therefore fruit production.
  • Potassium is a very important macronutrient once your tomato plants start bearing fruit, as their requirement for this element will increase in this stage of their lives.

When it comes to growing tomatoes, knowing which fertilizer to use is half the battle. In that sense, I have built this article to discuss the best tomato fertilizers in the business, organized in list format for your convenience

Choosing The Right Fertilizer For Your Tomatoes

In essence, every fertilizer performs the very same task; enriching both the soil and the affected plants, so that they may bear fruit of better quality. However, the type of fertilizer that you will need will vary depending on several factors.

In order to provide your plants with the optimal supplements for their growth, we would first need to study the soil they will be planted on. As I mentioned at the very start of this article, most plants require 3 macro-nutrients in order to grow and blossom healthily; Nitrogen (N), Phosphorus (P), and Potassium (K). In the crop-growing business, most gardeners refer to this group of nutrients as NPK, and when you actually go to purchase a fertilizer, you will see that each product has a set of three numbers, such as 2-4-1. These numbers represent the amount of NPK they offer, in that very same order.

After studying the soil and determining the amount of macro-nutrients it provides, you can now effectively choose which fertilizer best adapts to its requirements by supplementing the nutrients it fails to provide on its own. For instance, if the soil can provide nitrogen and potassium, but is lacking in phosphorus, you would need a fertilizer that provides more P and less NK (i.e. 5-15-10), and so on.

It’s important to note that some fertilizers also provide additional nutrients other than the basic NPK trifecta. Elements such as calcisum and iron, among others, can be used to promote specific aspects of your plants. For instance, they can be used to promote blossoming, which in turn may increase the rate and quality of the veggies. So keep an eye out for when a specific fertilizer offers these additional elements.


I know that picking the right fertilizer can be a daunting task at first; there are simply too many in the market, and all of them offer different amounts of nutrients and minerals. A good place to start would be to search for user reviews on your favorite search engine, to get an idea of what product might benefit your plantation best.

Remember that the idea of a fertilizer, besides promoting growth and plant health in general, is to supplement the soil’s weaknesses. With that in mind, I’m sure you will make the right choice in picking an appropriate fertilizer.
