What Is the Best Fertilizer for Tomatoes?
Tomatoes are an annual plant and are heavy feeders. This means that they need more nutrients than other plants. If you want them to grow throughout the season and produce the best fruit, you are going to need more than what is in the soil.
Fertilizers can be organic or chemical in nature. Either one can give your tomatoes the extra nutrients they need to grow fast and large. However, you may be wondering what the best fertilizer is, as there are many brands and options on the market.
The type of fertilizer you use depends on your soil. All soil has some nutrients in it. Therefore, you may want to have your soil tested to find out what is in it.
Sometimes, you can find at-home testing kits that are DIY. You purchase the soil test kit and follow the directions to test the soil around your home or in your garden. Of course, some soil brands include the nutrients and levels on the packaging, as well.
Once you know about your soil’s nutrient content, you can determine which fertilizer is best. If the soil is high in nitrogen or properly balanced, you need a fertilizer that is high in phosphorus and low in nitrogen. Consider using a 5-10-5 ratio or a 5-10-10 mixed fertilizer in this case.
The three numbers on the bag of fertilizer are called the NPK numbers and stand for Nitrogen, Phosphorus, and Potassium. Therefore, if you’re using the 5-10-5 ratio, it has double the phosphorus as it does potassium and nitrogen.
Soil that lacks in nitrogen requires a more balanced fertilizer with ratios of 10-10-10 or 8-8-8.
If it is impossible to have a soil test completed, it might be best to assume you have balanced soil. Then, you should use the fertilizer with a higher phosphorus level.

When to Fertilize Tomato Plants?
You should first fertilize your tomato plants when they are added to the garden. Then, you should wait to feed again until they have set fruit. Once the tomato plant starts producing fruit, it is best to give them more plant food every one to two weeks until the first frost arrives.
However, it should be noted that some fertilizers listed here had specific instructions. Some of them recommend that you wait to fertilize until the plant has been in the ground a few days. Always follow the directions on the plant food packaging.
How Often to Fertilize Tomato Plants?
Generally, you should fertilize the soil before the tomato plants are added. This ensures that the soil is prepared and has enough nutrients to start growing the tomatoes.
Once fruit appears, you should fertilize your plants once a week or once every two weeks. Do this for as long as the plant is growing and producing fruit.
However, some fertilizers are designed to be used once every three months. It is best to read the label on the plant food.
How to Fertilize Tomatoes?
It is often best to fertilize tomatoes while you are planting them. To do this, mix the fertilizer with the soil at the bottom of the hole. Then, add unfertilized soil on top.
Next, put your plant in the hole. It is not recommended to let raw fertilizer come into contact with the plant roots. This can cause burning.
If you have waited and the first fruit is set, water the plant well and add fertilizer. Some plant foods are designed to be mixed with water, which can take out a step in the process.
Those who use shake-and-dispense fertilizers should water first and then spread it evenly on the ground. Start about six inches from the plant’s base and go outward.
If you are looking for a good fertilizer for tomatoes, you have probably tried growing them before. It is important to choose the right plant food so that the tomatoes grow big, taste great, and look their best.
We have thoroughly reviewed these 12 products and believe the Miracle-Gro Water Soluble Plant Food is ideal. It has high amounts of nitrogen and phosphorus, so it works in many soil conditions. Plus, it is water-soluble, cutting out that step of watering first.
