Types of Tomato Fertilizer

There are many different kinds of tomato fertilizer with different methods of use.  The best type of fertilizer for your garden will depend on many different factors, such as the pH of your soil, the age of your plants and the stages of growth.  The first step is to test your soil to check the nutrient and pH levels so as to rule out any deficiencies.  However, if you have bought your soil especially for the tomato crop, this information will be provided on the soil packet itself.

In order to get the most effective tomato fertilizer for your garden, it is important to know what is out there to get the right option for your needs. For healthy growth, tomatoes need three different key nutrients: Nitrogen, Phosphorus and Potassium.  These nutrient levels will be provided in a ration such as 20-15-10 (N-P-K).  At planting stages, it is best to find a fertilizer with even levels of each of these nutrients to provide your plant with all round support during growth.

Nitrogen encourages healthy leaf growth and is the first of the three numbers in the ratio.  Most fertilizers have a high level of nitrogen because it makes leaves and lawns thick and green.  On a tomato plant, however, too much leaf growth reduces the number of flowers and tomatoes, so make sure the nitrogen level isn’t too high.

Phosphorus encourages flowering and therefore fruits, which makes it an important factor in the type of tomato fertilizer you buy.  This is an important nutrient to have high levels of at the growing phase to produce a larger crop. Potassium is the final nutrient which the tomato plant needs once it starts flowering to produce a healthier and thicker fruit.  Once your tomato fruit reaches flowering stages, swap from a high level of phosphorus to a high level of potassium to maximize your yield.

The best way to fertilize your tomato crops is to have a rotation of fertilizers which offer different support at different times.  However, we have a more in depth guide about this further on, so keep reading to find out more.

Problems You Can Prevent by Using Tomato Plant Fertilizer

Fertilizers are like the magic cure all to many problems gardeners face when growing tomatoes.  There are a number of problems tomato fertilizers can prevent depending on the fertilizer, so if you’re suffering from any of these common issues, a fertilizer exists to fix the problem.  Below are the most common issues gardeners face when growing tomatoes and the ways in which certain fertilizers can help solve these problems.

Poor quality soil

If you are growing tomatoes in the ground rather than in purchased soil, it may not be of a high enough quality to provide the tomatoes with what they need to grow properly.  This is where a fertilizer can be an excellent addition to your tomato plant.  Fertilizers can fix the pH of the soil as well as adding nutrients and vitamins your plant needs to grow healthy and happy.  Simply test the soil you are using to find out what the problem is, then look for a fertilizer with the right nutrients or pH level to put it right.

Low Yield

If you have a large tomato plant which isn’t producing as much fruit as it should, you might not have enough phosphorus at the growing stages.  A high phosphorus, low nitrogen fertilizer can help the plant to grow more flowers which will yield tomatoes and limit the amount of leaf growth which can reduce the number of flowers.  This will give your plant more likelihood of a higher yield in the following years so that you can really get the most out of every plant.

Small Tomatoes

If you have plenty of flowers but your tomatoes just aren’t reaching the size you want them to, you might not have enough potassium at the flowering stage.  A tomato fertilizer with a higher potassium level is the way to fix this because it supports the growth of the fruit rather than the plant.  Add this fertilizer at the flowering stage to support healthy growth of the tomato and you will find your tomatoes getting much larger.


Infestation is the enemy of the tomato grower and can be a difficult problem to solve if you’re only using insecticides.  Soft fruits and vegetables are more prone to infestation because they are easier to eat, which can make tomato plants very vulnerable to insects.  Many fertilizers, such as the Jobe’s Organics 9023 Fertilizer, are made with strong smells or are made to make the soil uninhabitable for insects to keep them at bay and keep your plants safe all year round.


Diseased plants are born from a lack of nutrition.  If your plant is not getting what it needs, it will start to die and rot, leaving it susceptible to diseases.  Fertilizers provide your plant with adequate support to ensure that it gets all the nutrients it needs to stay healthy and strong.  By using a fertilizer, you are helping your plant protect itself from disease and damage so that it will keep producing crops year after year.

Best Way to Fertilize Tomatoes

The best way to fertilize tomatoes is to have a cycle of different fertilizers at different stages of growth. There are many different methods of fertilizing tomatoes, such as with a soil based fertilizer, granules or a water soluble fertilizer.  These methods have benefits at different stages of growth, also.

Tomato plants should be fertilized at the planting stages with a balance of nitrogen, phosphorus and potassium to support seedling growth evenly.  This should be done with a soil based fertilizer to surround your plant with the nutrients it needs for proper growth and development.

Once the plant grows to the point where it begins to grow flowers, you can change to a lower nitrogen and higher phosphorus fertilizer which will help the plant produce more flowers which will grow tomatoes in the coming weeks.  This can be done with a water soluble fertilizer or granules, as long as the plant gets an even source of fertilizer.

When the flowers begin to produce tomatoes, switch to a higher potassium fertilizer to help your plant produce juicier tomatoes.  This can also be done with a water soluble fertilizer or with granules but a water soluble option is best to get the nutrients to the roots of the plant as quickly and efficiently as possible.

Whenever you fertilize a tomato plant with a water soluble or granule fertilizer, make sure that you spread the fertilizer around six inches from the base of the plant.  If you fertilize too close to the plant, the fertilizer may burn the plant stem which can cause irreparable damage to the plant.  Also make sure that the plant is watered well before fertilizing, as you can damage the plant if there is not enough water to dilute the strength of the fertilizer.

Tips For Using Tomato Plant Fertilizer

To make sure you get the most out of your plants, Surf’n’Buy have a few tips and tricks to using your tomato fertilizer.

Water, Water, Water

Fertilizers can be your best friend or your worst enemy.  If you haven’t sufficiently watered your plant before fertilizing, you can burn the plant and cause permanent damage, which means you will lose the plant.  Make sure to adequately water your plant before fertilizing and keep the fertilizer about six inches away from the base of the plant to keep your plant safe.

Create a Fertilizer Schedule

Your plant will need different things at different stages of growth, so to make sure it gets what it needs when it needs it, creating a schedule of different fertilizers at different times will help you give your tomato plant the right support for maximum growth.  We have given a full run down of what your plant will need at different stages of growth, so try to create a fertilizing schedule along these lines.

Keep Checking on Your Plants

Keeping a schedule is one way to make estimate when your plants need the right support at the right time, but plants are still a little unpredictable.  To make sure you know what your plant needs at all times, it is important to regularly check on your plant to see if it is flowering or beginning to produce fruit so that you can swap the fertilizers at exactly the right time.

Go Organic

Chemicals can produce fruit faster and more efficiently, but over time they will damage the plant and give it a shorter lifespan.  To protect your tomato plant and give it the longest life possible, organic fertilizers are the best way forward.  They can do all of the things that chemical fertilizers do whilst being better for your plant and better for the environment.  With all of the benefits of an organic fertilizer, why would you ever use chemicals?


So there you have it.  The secret to the perfect tomato crop is fertilizer and it is the key to getting the maximum growth from each of your plants this year, and every year after.  Starting with the Dr. JimZ Tomato Fertilizer will help your plant grow tall and strong at the initial phases, giving your tomato plant the best start in life. Once your plant gets a little older, it will need different kinds of nutrients and minerals.  This is where the organic fertilizers such as Jobe’s Organics 9023 Fertilizer and Greenway Biotech Tomato Fertilizer will continue to support the plant as it goes through flowering and producing fruit.
