Purchase Criteria
kind
Organic Tomato Fertilizer: It is considered a “natural fertilizer”. The tomato plant cannot use the nutrients immediately because they first have to be extracted from its organic structure. This happens through the substrate and/or the plants themselves. The substances are then ready for the tomato roots to absorb. While organic tomato fertilizer takes longer to work, once it does, it lasts longer.
Mineral tomato fertilizer: Unlike organic fertiliser, it is chemically produced. Mineral tomato fertilizer already contains the nutrients in their “pure” form. As a result, this fertilizer works faster. Attention: Mineral fertilizers can be toxic due to the "unnatural" manufacturing process. That is why there is a lot to be said for using organic fertilizers, especially for tomatoes (and other crops).
tips
In addition to the purely organic or mineral tomato fertilizers, there are also organic-mineral versions that combine both variants and are suitable as long as the organic content predominates.
consistency
liquid fertilizer: Simply mix liquid tomato fertilizer into the irrigation water. In most cases, it is designed for regular use every one to two weeks.
granules/powder/pellets: Tomato fertilizer in granulated, powdered or pelleted form work directly into the soil. It is usually a long-term fertilizer that you only have to use once or twice a year. Note: A perfect dosage and thorough incorporation are particularly important here in order to optimally care for your tomatoes.
fertilizer sticks: Fertilizer sticks inspire primarily because of their low-effort application. Once planted in the ground, they often last for weeks or even months. However, it is often difficult to determine the ideal dosage.

On the one hand, this concerns the starting materials used (e.g. humus, compost, etc.) and, on the other hand, the proportion of NPK. The three letters stand for nitrogen (chemical element N), phosphorus (P) and potassium (K). These substances are the most important for almost all plants, which is why they are also highlighted on fertilizers. For tomatoes, each of the nutrients mentioned should be readily available. Also extremely important: magnesium, iron, sulphur, manganese and boron.
organic quality
When it comes to crops such as tomatoes, it makes particular sense to give preference to organic products. The gardener wants to eat parts of his cultivated plants - this always works with a better conscience when he knows that the fruits do not contain any chemical substances or other harmful substances. This, in turn, can only be said with absolute certainty if everything from the seeds to the substrate to the tomato fertilizer is organic. So opt for organic fertilizers if possible.
pack size
Of course, the price-performance ratio also plays an important role in the purchase. Therefore, you should always take a look at the price in relation to the content. The price per liter or per kilo often decreases as the package size increases. In this sense, it can be worth investing in a tomato fertilizer that is rich in content in every respect.
youtubefrequently asked Questions
Why should I use tomato fertilizer?
Tomatoes are much more demanding than most other plants when it comes to the amount of nutrients they need. Tomato plants are heavy feeders - that is, they want a particularly well-laid table. Only then can they develop in the best possible way and produce delicious fruit. Good tomato fertilizer meets the needs of the plants by bringing higher levels of nitrogen, phosphorus and potassium than conventional universal fertilizers.
Attention: Even if tomatoes have a high nutrient requirement, you should not overdo it with fertilizer. Because over-fertilization has just as negative an effect as an undersupply of nutrients. In the worst case, the tomatoes burst and your dream of a bountiful harvest is gone. It is best to stick to the manufacturer's instructions and show a little instinct.
Is tomato fertilizer also suitable for other plants?
Yes, you can also "feed" other heavy-duty vegetables with tomato fertilizer, such as bell peppers, chili peppers, aubergines, potatoes, courgettes, cucumbers, pumpkins, practically all types of cabbage (e.g. rose, cauliflower and white cabbage), broccoli and corn.
Which brands offer good tomato fertilizer?
Tomato fertilizer is available from numerous manufacturers. Here is an overview of some selected brands:
- Compo
- Neudorff
- stretcher
- Grandiol
- Green Jan
- Beckman
- Oscorna
Where is the best place to buy tomato fertilizer?
If you are looking for high-quality tomato fertilizer, you will find it in every DIY store or garden center - for example at OBI, toom, Bauhaus, Hornbach or hagebaumarkt. Even in the drugstore (DM, Rossmann) or in the discounter (Lidl, Aldi - the latter with its own brand Gardenline) you can sometimes find solid tomato fertilizers at low prices. However, once again Amazon offers you the largest selection.
Can I make tomato fertilizer myself?
Yes, there are different ways you can make your own tomato fertilizer. For example, nettle manure and coffee or coffee grounds are popular home remedies for fertilizing tomatoes.
However, we advise you against making tomato fertilizer yourself. After all, with DIY experiments you generally have no precise overview of what nutrients the finished fertilizer actually contains. A convincing commercially available tomato fertilizer clearly gives you fewer headaches and increases the chance of healthy plant growth and lots of delicious tomatoes.
equipment
tomato soil
Even the best tomato fertilizer can only be fully effective if the substrate is right. Therefore, we advise you to match the soil to the specific needs of the tomato plants. In combination, tomato soil and fertilizer ensure the optimal supply of the heavy consumers.
