Best Fertilizer for Tomatoes: Reviews, Buying Guide and FAQs 2021

by Safa Patel

Organic tomatoes are the essence of backyard garden vegetables; however, they don't just appear out of nowhere. To grow tomatoes effectively, you'll need a good dose of perseverance, patience, sunlight, and soil fertility. Plant nutrition is, in fact, one of the key contributors to tomato taste and quality, as per the International Plant Nutrition Institute.

Many vegetable growers are preparing to harvest their summertime crops as the summer season approaches. Tomatoes from the garden are a must-have in every edible garden.

Tomatoes come in two varieties: determinate and indeterminate. Thus fertilization differs between the two types.

Bush tomatoes are another name for determinate tomatoes, and they only reach a certain height before bushing out.

Indeterminate tomatoes, on the other hand, are vining varieties that grow and blossom continuously.

There are two phases in the development of determinate tomatoes. Growing and fruiting are the two stages of the process. There is only the growth period with indeterminate tomatoes, and they will require constant fertilizer.


Fertilize your tomatoes to get the best results. The finest fertilizer aids overall plant growth, blooming, fruit production, and disease resistance for tomatoes. A healthy tomato plant will provide a great harvest of lovely fruit. Selecting the finest fertilizer for your plants of tomato's and growth circumstances needs extra investigation. Take a peek at some of the top contenders for the outcomes you're seeking.

Fertilizer Types for Tomatoes

There are three types of tomato fertilizers: water-soluble, granular and liquid. There are options for both chemical and organic fertilizers on each form. The year's season, growing conditions, weather changes, user-friendliness, and other considerations all play a role in determining which formulation is appropriate for a gardener's needs.

1. Granular Type

Granular fertilizer is simple to use, requires little preparation, and can be stored forever if kept cool and dry. Granular fertilizer is applied to the root system of grown plants by mixing it into the soil preceding planting or by distributing it over the root system of newly planted plants. Quick-release and slow-release granular fertilizers are available.

Slow-release type of fertilizer breaks down gradually, providing a consistent supply of nutrients for up to a whole growing season. Slow-release formulations are available as organic or inorganic treatments for gardeners. Quick-release fertilizers are inorganic components that dissolve in water and flow through the soils, giving you an immediate hit of nutrients.

2. Liquid Type

Liquid fertilizer is available in a concentrated version that must be dissolved in water before use. It is known for plant uptake instantly in both inorganic and organic forms. Many gardeners use weak liquid fertilizer solutions (i.e. half strength or even less) directly to plant leaves compared to the traditional approach of saturating soil surrounding plants with the help of liquid fertilizer.

There are various ways to apply liquid fertilizer, from essential spraying to regulated hose-end spray bottles that blend the concentration with the flowing water as it is released. Liquid fertilizer delivers a flush of nutrients quickly, but it must be sprayed frequently. If kept unopened and correctly stored, it has a long life span.

3. Water-soluble Type

Water-soluble fertilizers combine the storing facility of granular fertilizer with the quick-acting ability of liquid fertilizer. It is quickly available to plants after application. Water-soluble fertilizers, like all other types of fertilizers, are available in both organic and inorganic forms.

Water-soluble fertilizer comes in the form of micro granules or powdered fertilizer that quickly dissolves in water. Water-soluble fertilizer is used in the same way that liquid fertilizer is used.

Like many other annuals, Tomatoes are robust feeders that thrive when given lots of nutrients to help them grow throughout the season. Chemicals or organic fertilizers can aid tomatoes to get the extra nutrients they need to facilitate growth. What, on the other hand, is an excellent tomato fertilizer? When is the best time to fertilize tomato plants? Continue reading to get answers to your tomato fertilization questions.

When Should You Use the Fertilizers for Tomato Plants?

When planting tomatoes in the garden, they should be fertilized first. You can then begin fertilizing them once they have set fruit. Add light fertilizer once in between one-two weeks after the tomato plants start to grow fruits until the first frost damages the plant.

Fertilize Tomatoes in a Simple Way

While planting tomatoes, combine the fertilizer of the tomato plant with the soil at the base of the plant hole and then cover it with unfertilized soil before inserting the tomato plant in the hole. The tomato plant can be burned if unprocessed fertilizer comes into touch with the roots. Ensure the tomato plant is thoroughly watered before fertilizing once the fruits are completely set. If the tomato plant isn't adequately watered before fertilization, it may absorb too much fertilizer and burn. Sprinkle the fertilizer on the soil after watering the plant, starting about 6 inches (15 cm) from the root. Fertilizing near the tomato plant might cause the fertilizer to flow off onto the stem, resulting in the plant being burned.

The Finest Way of Fertilizing Tomatoes

Macronutrients like nitrogen, phosphorous, and potassium and critical micronutrients like magnesium, calcium, boron, and zinc are all included in the finest fertilizer for tomato plants: During each development cycle, tomatoes, on the other hand, require varying ratios of essential nutrients. If you're a beginner at gardening, correctly fertilizing tomatoes might seem difficult. Soil nutrition is a subject you wouldn't want to be uninformed about, even if you're planting from seed or seedling.

Your tomato plants will provide a fantastic yield year after year if you follow the instructions. But, before we go any further, let me confidently state that no specific tomato fertilizer works best over all types of gardens at all times of every year. Growing vegetables would be a pleasure if there were one. Let's explore some statistics and fertilizer alternatives to assist you in choosing the best one for your plant's stage of development.

Tomato Plant Fertilization Basics

Every nutrient must be present all the time; yet, the recommended nutritional ratio varies with each growth stage.

  • The roots of a tomato plant should not be more than 6-7" deep.
  • Commercial fertilizers are labelled with a sequence of 10-8-10, which stands for nitrogen, phosphorous, and potassium (or elements N-P-K). It signifies that the fertilizer comprises 10% nitrogen, 8% phosphorous, and 10% potassium, with the residue being filler.

Fertilizer is also required for fully developed plants.

During this time, keep a close eye on the plant for clues about what fertilizer it requires. Indeed, requirements depend on various circumstances, including the variety of tomatoes, the soil, and the surrounding environment.

No measure of tomato fertilizer will assist if these instructions are not followed correctly. Take into account that plants are pretty resilient. To go beyond this level, you don't have to be an expert. Understanding what has to be done, on the other hand, is beneficial.

Why Roots of Your Tomato Plant Are Important

Your tomato fertilizer of selection won't make a difference until your tomato plant can absorb nutrients you've added to the soil. You'll need to ensure that the tactics of your watering stimulate deep roots to guarantee root health. The plants will not only increase in size and girth, but they will also branch out, leading them to become top-heavy. To keep the plants from falling and tumbling over, you may wish to give some external support. Deep roots also aid it.

Second, it's ideal for putting your tomato plant in the soil or an enormous container because narrow containers cause root clumping and a plant's roots that are too overcrowded struggle to absorb the nutrients it requires.

Fertilizer for Tomato Buying Guide

What to Keep in Mind When Purchasing Tomato Fertilizers

Every garden is different. No fertilizer is optimal in every situation because of variations in soil texture, natural richness, drainage, pH, and other considerations. It's beneficial to have a variety of fertilizer levels available to meet the demands of plants at various stages of growth. When looking for the finest tomato fertilizer, keep these things in mind.

The state of the soil

The most reliable approach to determine whether or not a garden can produce tomatoes would be to have the soil assessed. Soil analysis determines the existing amounts of the critical minerals and micronutrients in your soil. The findings will include suggestions for adding soil additives to enable the ground into the acceptable range for growing.

In the United States, each state has a cooperative extension agency that helps farmers and household gardener's plant crops. One of the services they offer for a minimal price, usually between $15 and $20, is soil assessment.

Composition of Chemical Fertilizer

The three primary nutrients in fertilizer are nitrogen (N), phosphorus (P), and potassium (K). Nitrogen is the ingredient that causes leaves to grow-phosphorus aids in the growth of roots, flowers, and fruits. Potassium helps plants develop strong stems and maintain overall health. The essential nutrients are listed visibly on the packaging in a ratio of 4-6-4 and always in the order N-P-K. The ratio indicates how much each ingredient contributes to the total volume of the fertilizer. A fertilizer with a 4-6-4 ratio is 4% N, 6% P, and 4% K.

Fertilizers may not always contain micronutrients in addition to the primary nutrients. Micronutrients are usually listed in a less prominent place on the label. Micronutrients serve a small but important function in plant development. Calcium, magnesium, sulfur, manganese, zinc, boron, and copper are beneficial to tomatoes.

Fertilizer for Tomato Frequently Asked Questions

How much fertilizer does a tomato plant require?

Answer: The timing, regularity, and rate of application differ depending on the product. Be careful to follow the fertilizer label's application directions.

What is the best way to fertilize tomato plants?

Answer: Granules can be applied by integrating them into the soil before planting or scattering them on the ground surface. Wet the soil of ground around the tomato plant with liquids prepared according to the label's recommendations.

Do you fertilize tomato plants regularly?

Answer: Each fertilizer component degrades or is uniquely utilized by the tomato plant. Applying two or three treatments of granules throughout the growing season is generally sufficient. Use a liquid fertilizer every two to three weeks. Read the product labels with caution.

What micronutrients does a tomato plant require in fertilizer?

Answer: Phosphorous is necessary for root development, potassium for blooming and average growth, and nitrogen for leaves.

  • Phosphorus is needed for the formation and development of both roots and fruit. Therefore it is a crucial nutrient in the beginning and then again in the end.
  • Nitrogen takes good care of the leaves, but too much nitrogen leads to bushy plants with little fruit.
  • Potassium aids the plant's rapid growth and production of blooms and fruit. However, when it comes to photosynthesis and disease resistance, it's critical.

Do I need to fertilize my tomato seeds?

Answer: You do. After the tomato seeds have sprouted, they will develop rapidly, with an initial growth spurt immediately before blooming. They usually yield fruit after four months of it being planted, as a matter of thumb.

How can I know whether I need to fertilize my soil with nitrogen?

Answer: You won't know for sure unless you examine your soil. Yet, if you're using fresh compost, you don't need to feed any nitrogen at all, simply phosphorus during the early stages of development (that is, soon after transplanting the seeds). If your compost has a lot of banana skins and bones, you might not even need to add phosphorus.

What is the role of phosphorus, potassium and nitrogen in tomato plant growth?

At different phases of their life cycle, tomatoes require additional nutrients. If your plants are seedlings with green leaves springing from the ground, you'll need a tomato fertilizer with high phosphorus content. If you have existing tomato plants, you should use a tomato fertilizer with added potassium. Although nitrogen is necessary for leaf growth, excessive nitrogen can result in plants with a lot of foliage but very little fruit.

Conclusion for Fertilizer Buyers

A quality fertilizer may assist you in providing all of the nutrients required for a healthy tomato yield. It's critical to follow fertilization instructions and avoid over-fertilization, as it is more detrimental than under-fertilization.

There is no one-size-fits-all fertilizer for tomatoes; instead, choose your fertilizer depending on your plant's development stage and soil conditions.

If the soil is nitrogen-rich, use a fertilizer that is lower in nitrogen and rich in phosphorus. If the soil is deficient in nitrogen, use a balanced fertilizer.

Final thoughts as a reminder

  • Fertilize all tomatoes in the late spring or early summertime. Please read all of the directions carefully and follow them strictly.
  • Granular, liquid, and spike fertilizers are the three forms of tomato fertilizer. Each one is designed to satisfy the specific demands, and you may need to utilize all three.
  • If you want to increase the soil and plant growth, organic is an excellent tomato fertilizer to apply.
  • I suggest having your soil analyzed, selecting whether to use organic or inorganic fertilizer and determining the sort of NPK combination you require.
  • Any of the nine fertilizers listed above are excellent choices. All are inexpensive, simple to use, and may significantly boost the development and blooming of your tomato plants.
  • Buy Kelp Meal or Alfalfa Meal if you want to utilize an alternate solution to commercial fertilizer.
