Frequently Asked Questions
1. What is a NPK Ratio?
NPK stands for the ratio of Nitrogen to Phosphorus to Potassium.
Typically, tomatoes need 1/2 pounds of fertilizer per 50 square feet of garden.
For almost all tomatoes you will want a fertilizer with a 6-24-24 or 8-32-16 ratio.
2. How Do I Choose a Tomato Fertilizer?
Choosing a Tomato Fertilizer will depend on what you want them to do.
- Bloom Boosting Fertilizer – This is good for tomatoes that struggle to grow throughout the summer or grow flowers.

4. What are the Different Types of Tomato Fertilizers?
Granular fertilizer is a dry fertilizer that can be applied with a spreader or shaken.
One of the benefits of this type of fertilizer is that you can see the actual fertilizer. You can also see where you have applied it and where it needs to be applied.
This type of fertilizer can be slow-release or quick-release.
Slow-Release fertilizer releases nutrients steadily over an extended period of time. This means you only have to fertilize once or twice a year.
Quick-Release delivers nitrogen immediately. Because of this, you will need to fertilize frequently.
Make sure you read the instructions of the fertilizer to have a better understanding of how to do this.
Another type of fertilizer for your tomatoes is liquid fertilizer.
Liquid fertilizer needs to be diluted before it can be applied. It can be applied using a canister, hose, or a watering can.
It is easy to apply and is quickly absorbed.
One of the disadvantages of this type of fertilizer is that it can wash away from the rain.
So make sure to apply this when no rain is in the forecast.
The final type of fertilizer that can be applied to your tomato is spikes.
Spikes are fertilizer in the shape of sticks. This is a slow-release fertilizer meaning it will be released over time.
It is applied directly to the ground and is incredibly easy to use.
This is perfect for beginner tomato growers.
5. What Should I Consider When Buying Tomato Fertilizer?
Below, are 4 Tips I recommend before purchasing fertilizer.
Tip 1 – Get your soil tested!
Before you purchase the BEST Tomato Fertilizer you must first understand what nutrients your tomato currently lacks.
For this, you will want to conduct two tests.
You will first need to conduct a soil test. For this, I recommend purchasing a home soil test.
Next, I recommend continuously testing your soil. For this, I recommend a pH Meter.
Tip 2 – Fertilize with the right nutrients!
When analyzing your soil test there are numerous nutrients your plants may need.
Below, is a list of the nutrients plants need for strong growth.
- Carbon – This is found in the air and is essential for plant growth
- Hydrogen – This is found in water and again is needed for plants to grow strong
- Oxygen – This is found in water and air. This is a key component that all other nutrients will use to help plants grow.
- Nitrogen – This is the most lacking nutrient in garden soil. This is the one nutrient that can help plants grow the fastest
- Phosphorous– This nutrient helps stimulate root growth
- Potassium – This nutrient helps plants become more disease and drought-resistant
- Magnesium – This helps plants better process sunlight
- Sulfur – This nutrient provides plants with protein. This is the building block of life
- Other nutrients that are needed for plant growth are boron, copper, iron, zinc, chlorine, and manganese.

Tip 4 – Decide on Organic or Synthetic
My next tip for deciding on the Best Tomato Fertilizer is simple:
Buy either organic or synthetic fertilizer.
Synthetic fertilizer releases nutrients quickly and should be applied in the spring.
- This type of fertilizer comes in liquid, granular, or spikes.
Organic fertilizer releases nutrients slowly and should be applied in the fall. It typically is not concentrated meaning that the odds of killing plants are much less.
Below, are my three favorite organic fertilizers.
Tip 4 – Learn the best time to fertilize!
While a soil test is a great way to determine what nutrients are lacking, there are other things to beware of.
- You can tell if there is a fertilizer deficiency if your plants have yellow or small leaves.
- In addition, there is a deficiency if there is poor flowering
- Finally, there is a deficiency if the plant is small.
- You can tell if there is too much fertilizer if you have all yellow leaves. In addition, there is too much fertilizer if there are poor quality flowers
6. When Should I Fertilize Tomatoes?
When you should fertilize tomatoes depends on the fertilizer you use and the soil.
- Always read the instructions for best use!
- Apply a fast-release fertilizer in May, June, or even July to promote the best growth
- Apply a slow-release fertilizer as soon as you plant your tomatoes into the garden to promote the best growth.
