10 Best Fertilizer for Tomatoes 2024 – Buying Guide & Reviews

Are you keen on growing tomatoes in your greenhouse or pots? When they have grown and made, they can be a beautiful plant and provide you with a tasty treat. But you have to make sure they grow properly before you can eat the fruit.

Many people think they need more than water and sunshine, so they search for fertilizer. There’s plenty on the market though.

Today, we’ll think about 10 different things. Instead, we will tell you the best Fertilizer for Tomatoes so you have all the details you need.

What Is the Best Fertilizer for Tomatoes?

Tomatoes are an annual plant and a heavy feedingstuff. It ensures they require more nutrients than those of other plants. When you want them to grow all season and yield the best fruits, you’ll need more than what’s in the soil.

Fertilizers can be naturally organic or chemical. Either one can offer the extra nutrients your tomatoes need to grow fast and high. You may wonder what the best fertilizer is, though, because there are several brands and options on the market.

The kind of fertilizer that you are using depends on your soil. Every soil has some nutrients in it. And you may want your soil checked to find out what’s inside it.

Often at-home test kits can be found which are DIY. You buy the soil test kit, and follow the instructions for checking the soil around your home or garden. Some soil brands of course also contain the nutrients and amounts on the packaging.

If you know the nutrient content of your soil, you will decide which fertilizer is the most suitable. If the soil is high in nitrogen or is properly balanced, a high in phosphorus and low in nitrogen fertilizer is required. Try, in this case, using a 5-10-5 ratio or 5-10-10 mixed fertilizer.

The NPK numbers are called the three numbers on the fertilizer bag and stand for Nitrogen, Phosphorus, and Potassium. If you use the 5-10-5 formula, then, it has twice the phosphorus, as it does potassium and nitrogen.

Soil deficient in nitrogen requires a more balanced fertilizer with a 10-10-10 or 8-8-8 ratio.

If a soil check can not be done, it may be safer to presume you’ve got healthy soil. Instead, use the fertilizer with a higher amount of phosphorus.

When to Fertilize Tomato Plants?

First, you can fertilize your plants with tomatoes when they are introduced to the garden. Instead, you can wait until they have set fruit again to feed. When the tomato plant starts to bear fruit, it is best to give them more vegetable food every one to two weeks before the first frost occurs.

It should be noted, however, that some of the fertilizers mentioned here had unique instructions. Most of them suggest that you wait until the plant has been in the field for a few days to fertilize. Often follow the instructions on the labeling of plant foods.

How Often to Fertilize Tomato Plants?

You will usually be fertilizing the soil before adding the tomato plants. It ensures the soil is prepared and has enough nutrients for the tomatoes to begin developing.

When fruit emerges, the plants should be fertilized once a week, or once every two weeks. Do so for as long as the plant grows and produces fruit.

Most fertilizers are intended, however, for use once every three months. Understanding the mark on plant foods is safest.

How to Fertilize Tomatoes?

Tomatoes are also better fertilized when you are planting them. Mix the fertilizer and the soil at the bottom of the pit to do so. Then pour to unfertilized soil.

Then place your plant inside the opening. Letting raw fertilizer come into contact with the plant roots is not recommended. It can lead to burns.

Water the plant well, and apply fertilizer, if you have waited and the first fruit is set. Some plant foods are intended for mixing with water, which may take a step in the process.

Those that use shake-and-dispense fertilizers will first spray, and then uniformly scatter it on the ground. Start from the base of the plant about six inches, and go outward.


When you’re looking for a decent tomato fertilizer you’ve probably tried growing it before. Choosing the right plant food is critical so that the tomatoes grow high, taste great, and look good.
