Tomato fertiliser can be used for different plants. It is not only tomatoes that benefit from the many nutrients. In general, tomato fertiliser is always important when you have a plant. It doesn't matter if you have a small tomato plant on the balcony or if your garden is full of plants.

Nevertheless, there are various aspects that need to be taken into account. This is exactly why we have written the following guide with the corresponding recommendations. You will find out exactly what you have to pay attention to when buying. We also answer the most important questions about tomato fertiliser.


  • Tomato fertiliser differs mainly in consistency. It is available in powder, liquid and granular form. Depending on the type of fertiliser, it is applied differently.
  • The tomato fertiliser is used for different periods of time. With some manufacturers, a single application shortly after sowing is sufficient. Other fertilisers need to be applied every few weeks.
  • Tomato fertiliser can also be used for other plants. In most cases, cucumbers, courgettes and peppers can also be fertilised with it. However, it depends on the respective manufacturer's instructions.

The Best Tomato Fertiliser: Our Picks

There are many tomato fertilisers on the market. But not all fertilisers are suitable for everyone. That's why we have selected the best products for you. Depending on what you want to use the fertiliser for and how often, you will find the ideal product here.

Buying and Evaluation Criteria for Tomato Fertiliser

We do not advise you to buy tomato fertiliser at random. You should consider some criteria to find the ideal fertiliser for you. We have summarised the most important buying criteria for you.

If you don't know what to do with this list and want to read more, take a look at the individual criteria. We have explained them in detail for you. This way you are ideally prepared for your purchase.


The quantity depends on how often you want to use the tomato fertiliser. If you have a lot of tomato plants, then an XXL tomato fertiliser package is ideal. If, for example, you only have one tomato plant on your balcony, then a smaller package is sufficient.

The small packages usually start at 500 g. There are hardly any limits for the large packages. These are even offered in 10 kg boxes. The quantity can be given in litres. This is the case when it comes to a liquid tomato fertiliser.


Suitability tells you what the tomato fertiliser can be used for. Many tomato fertilisers are in fact labelled as such, but can be used for other plants.

Depending on the ingredients, the fertiliser may also be suitable for cucumbers, peppers or even fruit such as currants.

The manufacturer's instructions often describe what the tomato fertiliser can be used for. This means that you only need to buy one fertiliser, which can be used for the entire garden.


The ingredients vary depending on the tomato fertiliser. Many tomato fertilisers contain sheep's wool. This makes it a natural fertiliser without chemicals. There are also organic tomato fertilisers.

This does not necessarily contain sheep's wool. Rather, it consists entirely of natural ingredients. Finally, there are conventional tomato fertilisers. These often contain important vitamins such as magnesium and potassium.


An important purchase criterion is the consistency of the fertiliser. This is generally available in powder, liquid and granule form. Liquid tomato fertiliser is usually easy to dose. This is due to the dosing aids that are available. The powder form is often available in large quantities. Granules are ideal for direct incorporation into the soil.

There are also tomato fertiliser sticks. These have all the ingredients in the form of a stick. This means that you only have to press the stick into the soil. Depending on the consistency you prefer, you have to pay attention to this criterion.


The application usually depends on the consistency of the tomato fertiliser. This does not mean that this is necessarily the case. Sometimes the application differs. Some fertilisers are used when the first flowers appear.

This is usually the case after 2 weeks after planting. Some fertilisers are used throughout the season. If you only want to use the tomato fertiliser once, then you should pay attention to this information.

Guide: Frequently asked Questions about Tomato Fertiliser answered in Detail

In our tomato fertiliser guide we have answered the most frequently asked questions. You will find answers that will make you a real professional in the field of tomato fertiliser. We have also put together a price table for you.

Who is tomato fertiliser suitable for?

Tomato fertiliser is suitable for supplying tomato plants with more nutrients. This makes them grow faster. At the same time, they become more robust against external weather influences and pests. This results in a larger harvest. The harvest itself is more abundant. This is because the tomatoes can get a stronger colour and better taste.

Accordingly, tomato fertiliser is suitable for everyone who has one (or more) tomato plants. It doesn't matter if you're an amateur gardener or already have gardening experience. Tomato fertiliser can be used on the balcony or in the garden.

What types of tomato fertiliser are there?

Tomato fertiliser comes in different types. These cannot be exactly separated from each other. For one thing, the fertiliser differs in its form. There are liquid and powder fertilisers. There are also coarse-grained granules and sticks.

All these forms of tomato fertiliser come with different ingredients. Conventional fertiliser often contains potassium and iron. As an alternative, there are organic fertilisers and tomato fertilisers from organic cultivation.

How much does tomato fertiliser cost?

Tomato fertiliser is available in different price categories. Depending on the price category, there are different types of tomato fertiliser. To give you an overview, we have put together a table here:

Price category Scope of services
Low-priced (3 - 6 €) Small quantities, rarely organic quality
Medium-priced (7 - 12 €) Higher quantities, often organic quality
High-priced (from 12 €) Almost always organic quality, long-lasting effect

How do you make tomato fertiliser yourself?

You can make tomato fertiliser yourself. An alternative is coffee grounds. Coffee has natural ingredients that improve growth. These are mainly potassium and nitrogen. These two substances are contained in conventional tomato fertiliser.

If you have coffee grounds left over, spread them on the soil of your tomato plants. Lightly press the coffee into the soil. You can repeat this process about 2 - 3 times each season. By the way, it does not matter whether the coffee grounds come from a filter machine or a fully automatic coffee machine.


Not all tomato fertiliser is the same. That's why it was important that you read through our buying criteria first. The different consistencies can influence the application. Furthermore, tomato fertiliser is suitable for everyone who has at least one tomato plant. They don't even have to be tomato plants. Tomato fertiliser is also suitable for other vegetables.

With our buying criteria and our guide, you can now choose the ideal tomato fertiliser. You can even start by using coffee grounds as fertiliser. However, other biofertilisers have other nutrients that promote the growth of the plant.
