Reasons to get fertilizer for tomatoes

10 Best Fertilizers for Tomatoes – Healthy Plants and Juicy Fruits!

For the healthy growth of a crop, it’s essential for the soil to be enriched with nutrients. These nutrients normally occur naturally in the soil, and they allow the tomatoes to grow healthy and large. But more often, the soil can exhaust its nutrients, so for the continued growth of the tomatoes, fertilizers containing those nutrients need to be applied. Otherwise, the plant may stop growing or may succumb to the disease.

Organic matter, chemical fertilizers, or hybrid fertilizers that contain essential nutrients such as nitrogen, phosphorus, and potassium can enrich the soil. Moreover, fertilizers allow you to keep track of the exact amount of nutrients the plant is receiving, and thus, allows you to make a choice based on the soil you have. Just like humans need nutrients to grow healthy, tomatoes require nutrients to grow large and strong as well, and this nourishment is derived from the use of fertilizers.

How to pick the best fertilizer for tomatoes?

Every plant needs a fertilizer that works best for it, depending on its type – for example, there are special fertilizers for fruit treesfertilizers for roses or fertilizers for lawn grass. The reviews showcased different fertilizers for tomatoes, and the market has hundreds of various products as well. This makes it tougher to pick one, which is ideal for your tomato plant. However, we help you narrow it down by comparing the fertilizers according to different factors such as type, form, content of nutrients, and net weight and consumption. By discussing these factors and their importance, you will be able to select one fertilizer that best suits your requirements and help your tomato plant grow larger.


Organic fertilizers are derived from natural ingredients instead of ingredients that are chemically manufactured in a lab. Their method is to act as a probiotic to enhance the absorption of the soil. The benefit of its application is that it’s relatively safer to use for people and animals as there are no chemicals involved. However, on average, organic fertilizers are more expensive, and you won’t get weed control here.

With a synthetic fertilizer, the nutrients are chemically manufactured in a lab. They are less costly but still can improve the appearance of your garden while also providing the essential nutrients to the plant.

A hybrid fertilizer, such as the Neptune’s Harvest Tomato & Veg, is partly organic but also has minimal traces of synthetic elements. It helps to form a bridge between the previous two kinds of fertilizer to create the best of two worlds.


Fertilizers are available in different forms ranging from granules to liquid concentrates. Granular fertilizer is more efficient for a heavy pre-plant application and is also available in options that provide slow release. Moreover, they are usually less expensive if you buy a larger package.

Dry fertilizers are beneficial to be used for a large land as they last longer and are known to be less damaging to the plants, unlike liquid fertilizers that are known to sometimes burn the plants.


Liquid fertilizers for tomatoes are becoming more popular because of their ease of application. Moreover, they provide a uniform spreading and are easy to blend.

Granular and dry fertilizers are applied either by hand or by a spreader along rows of plants. Liquid concentrates, such as the Urban Farm Fertilizers Texas Tomato Food, are first mixed with the water and then applied using a water can, a sprinkler, or a sprayer.

10 Best Fertilizers for Tomatoes – Healthy Plants and Juicy Fruits!

Content of nutrients

The three major components of fertilizer for tomatoes include nitrogen, phosphorus and potassium. As the leaves of plants cannot freely absorb nitrogen through the air, it needs to be supplied in the form of fertilizer. The nitrogen makes the tomato plant healthy with green leaves. However, an excessive nitrogen application can stunt fruit development and focus more on stem and leaf growth. Phosphorus is good for root development and is relatively slower-acting than nitrogen. Lastly, potassium allows the tomato plant to stay strong during drought and other conditions and feeds and nourishes the soil over time. This is done by helping the plants process the ingredients and water.

However, fertilizers contain more than these basic macronutrients. They contain calcium to prevent blossom-end rot, sulfur, and boron for a healthy tomato plant, and magnesium, which helps with photosynthesis.

Net weight and consumption

The net weight and consumption rate are essential factors that affect a buyer’s decision. On average, granular and dry fertilizers contain 3-4 lbs of the mproduct as the Espoma Tomato-tone Organic Fertilizer. However, the JR Peters Jack’s Classic Tomato FeED contains 1.5 lbs of product, which can be great if you have a smaller garden.

As for the liquid concentrate, for application, they are to be mixed with water to make a larger amount of fertilizer.


The Urban Farm Fertilizers Texas Tomato Food can make 256 gallons of ready-to-use fertilizer from one gallon of the liquid concentrate. The consumption depends on different factors, but on average, it should feed around 1000-2000 sq. ft. of land. For instance, the dry Miracle-Gro Water Soluble Tomato Plant Food is applicable to 1,200 sq. ft. of land, while liquid concentrate can be applied to a larger land area. For example, the Neptune’s Harvest Tomato & Veg feeds 2,000 sq. ft. of land area.

Fast-acting vs. slow-acting formula

When a tomato fertilizer is labeled as “fast-acting” or “slow-acting”, they refer to the fast or slow release of nutrients to the garden. The quick-release fertilizers are generally more water-soluble and dissolve quicker in the soil. This enables you to witness a growth instantaneously, and this comes in handy in the early growth stages of the plant. However, too much use of this will cause stunted root development and increase shoot growth, which can be harmful to the plant.

The slow-acting formula for a fertilizer releases the nutrients slowly over an extended period, allowing nutrients to be in the soil for a long time. This decreases the need for frequent fertilizer applications. However, you won’t witness the instant growth of the plant.

There is no single formula, which is beneficial to the plant, which is why you should always try different methods. However, slow-acting formulas are generally considered better.


Blossom-end and splitting prevention

10 Best Fertilizers for Tomatoes – Healthy Plants and Juicy Fruits!

Blossom-end rot causes tomatoes to become discolored and watery – no one wants that. However, the cause is known to be a deficiency of calcium nutrient and erratic watering. It can also occur because of the excess of nitrogen in fertilizers. Fluctuations in the moisture of a soil cause BER to occur. However, a fertilizer, which is rich in calcium, can help enrich the soil to prevent blossom-end rot and splitting from occurring. A fertilizer that is full of calcium as a micronutrient along with nitrogen helps mitigate the harmful effects of nitrogen and leads to a healthy tomato plant resistant to multiple diseases. One of the fertilizers that contain calcium as part of its chemical composition is the Vigoro Tomato and Vegetable Garden Plant Food Plus Calcium.


The price is an important factor that determines whether a fertilizer and its features are truly worth it. Generally, organic fertilizers are known to be more expensive than chemical fertilizers. However, the Tomato-tone Organic Fertilizer and the Miracle-Gro Water Soluble Tomato Plant can be found at only $10. It depends on what your preferences, but the Editor’s Choice is packed with benefits, such as BER protection, perfect nutrient balance, and environment-friendly formula. However, if you prefer it in a liquid concentrate, they are priced higher in the range of $21 to $35. The innovative product TeaDrops can be found at the higher end of the scale, at about $35.


For healthy growth of the plant, tomatoes should be fertilized initially when they are planted in the garden. This helps the soil prepare and be enriched to allow the plant’s growth. Next, you will have to wait patiently until they set fruit and fertilize the plant again to prevent the risk of diseases and BER. Lastly, when the tomato plants start sprouting fruit, you will have to reapply the fertilizer lightly once every two weeks, and most of the fertilizers, on average, recommend the same. However, for a much accurate result, you should carefully read the instructions specified in the fertilizer as a fast-acting formula might need to be reapplied more often than a slow-release formula. Moreover, every plant requires specific levels of N-P-K, and you should keep that in mind if you want to use that on vegetables as well.

If you have purchased a fast-acting formula fertilizer, you will begin to see immediate results almost after the application. However, fertilizers, on average, need a couple of weeks until you notice a considerable shift in results. With the slow-acting formula, the product focuses more on establishing the nutrients of the soil. Moreover, you will need to complete an entire life cycle of the plant to see if the fertilizer prevents blossom-end rot and other diseases. However, it should be noted that the healthiness of the plant can be witnessed within days after application.

Chemical fertilizers that are created for specific plants are not as dangerous as some people might think. Even the organic fertilizers that made from natural ingredients can be harmful to pets and humans if consumed as they still contain high levels of certain ingredients. They are still not harmful to the environment. Chemical fertilizers, especially liquid concentrates, are known to cause chemical burns as they release nitrogen too fast for a plant. They are also known to cause air pollution as nitrogen can contribute to the greenhouse gases when plants cannot absorb more of the fertilizer. Apart from this, some chemical fertilizers also cause soil depletion, soil acidification, and can even be harmful to pets and humans to walk on a chemically fertilized area. So make sure to read the instruction before using them to ensure that they are safe.
