Fertilizers. There are dozens of options, each boasting numbers, and symbols that seem utterly foreign to the untrained eye. Some have a mixture of numbers, while others boast three of the same number. For example, 13-13-13 and 10-10-10 – they’re the same, right?
After all, they’re both all-purpose fertilizers with balanced amounts of nutrients, so they’ve got to be essentially the same.
Well, while they are similar, the ratios of each fertilizer are entirely different, which plays an essential role in determining the best option for your lawn or garden.
So, if you’re stuck between 13-13-13 and 10-10-10 fertilizers, wondering which is the best option for your lawn or garden, you’re in the right place. We’re here to explain each choice and when you should use it, so continue reading to learn more!
What are 13-13-13 and 10-10-10 Fertilizers?
When shopping for fertilizers, you’ve probably come across 13-13-13 and 10-10-10. These three numbers represent the fertilizer’s percentages of nitrogen, phosphorus, and potassium (respectively).
Nitrogen, the first of the trio, plays an essential role in plant growth and aids in leaf development. Phosphorus is crucial for healthy root growth and helps plants produce flowers and fruits. Last but not least, potassium is necessary for overall plant health and aids in disease resistance and stress tolerance.
Both of these fertilizer ratios, 13-13-13 and 10-10-10, are considered “complete” fertilizers because they contain all three of these essential nutrients. However, while they fall into the same category, they’re not quite the same.
As the numbers imply, each option contains different amounts of these nutrients. The 10-10-10 fertilizer contains 10% nitrogen, 10% phosphorus, and 10% potassium. Given its ratios, it’s a popular pick for general gardening and is often used for lawns, vegetables, and flowers. It’s an excellent all-purpose fertilizer you can use throughout the growing season.
Next up, we have 13-13-13 fertilizer, which contains 13% nitrogen, 13% phosphorus, and 13% potassium. This fertilizer is a staple for crops requiring loads of nutrients, like corn and tomatoes. In addition, it’s a solid pick for plants growing in poor soil conditions or for those that need a boost in growth.
Nutrient Ratios in 13-13-13 and 10-10-10 Fertilizers
The three numbers on a fertilizer label or package represent the ratio of three key ingredients: nitrogen (N), phosphorus (P), and potassium (K). Each nutrient is necessary for different amounts for plants to promote growth, flowering, and fruiting.
These particular fertilizers, the 13-13-13 and 10-10-10, contain equal amounts of N, P, and K, but the ratios differ. In the 13-13-13 fertilizer, for every 13 parts of N, there are 13 parts of P and 13 parts of K.
On the other hand, the ratio of the 10-10-10 fertilizer is a bit different. This fertilizer has a balance of 1:1:1, meaning that for every part of N, there is one part of P and one part of K.
This might sound like gibberish, but what does it mean for your plants? The higher nutrient ratio in the 13-13-13 fertilizer is usually a more suitable choice for plants requiring more balanced nutrition. For instance, plants like fruits and vegetables often need equal amounts of each of the three essential nutrients.
They’re vital for healthy growth and development, so this ratio is ideal for fruits and vegetable plants.
Conversely, plants that need specific ratios, like those that need more phosphorus for root development or those that need more potassium for flowering, may benefit from a 10-10-10 fertilizer.
Ultimately, the best fertilizer hinges on the plant’s needs. It’s essential to note that while both fertilizers contain the same amount of nutrients, the actual amount of N, P, and K applied to your plants hinges on the amount of fertilizer you use.
When applying fertilizer to your lawn or garden, always follow the recommended application rates and instructions on the package, as over-fertilizing can cause damage to your plants.
Benefits of Using 13-13-13 Fertilizer
Choosing the right fertilizer can be the difference between a flourishing plant and a distressed one, as different plants need varying nutrient ratios. While 10-10-10 fertilizer is a popular choice, 13-13-13 fertilizer offers a few benefits that make it a worthwhile consideration.

When to Use 10-10-10 Fertilizer
While 10-10-10 fertilizer isn’t a catch-all option, it can be an excellent option in specific scenarios. Here are a few situations where 10-10-10 fertilizer might be the perfect solution:
- When you’re unsure what your soil needs: If you haven’t gotten around to testing your soil quite yet, 10-10-10 fertilizer can be a solid interim option to use until you get the results. It’s an all-purpose option that provides an even balance of nutrients without overdoing it on any of the three essentials, so it works for many plants.
- When you’re planting new plants: This fertilizer can be the perfect option when dealing with new plants, as it provides them with the nutrients they need to establish solid roots and robust, healthy growth.
- When you’re maintaining a lawn: Although most grasses enjoy the high nitrogen content some fertilizers offer, 10-10-10 fertilizer can still be a good option for maintaining a thick, healthy lawn. It provides a solid balance of nutrients that keeps your lawn vibrant and dense, so it’s a great pick without the headache of meticulous research.
Remember, while 10-10-10 fertilizer is a strong pick as an all-purpose option for balanced nutrients, it might only be suitable for some applications. If you have specific plants or soil conditions that require varying amounts of certain nutrients, you will likely be better off using a different fertilizer.
In almost any scenario, testing a soil sample is a good idea, as it’ll give you an idea of what your soil is rich in and what it’s lacking. With the test results, you can make an informed decision on the best fertilizer for your plants.
What Fertilizer Should You Choose?
Selecting the best fertilizer based on factors specific to your scenario can be a daunting task. Each option has its merits, and the 10-10-10 and 13-13-13 fertilizers are both all-purpose fertilizers containing the same essential nutrients. So, which one should you choose?
It all comes down to the ratio of these nutrients, what your soil lacks, and what your plants need. For example, if your plants need a higher amount of phosphorus, which is typical of flowering plants or vegetables, the 13-13-13 fertilizer might be the better fit.
Since this mixture has a higher amount of phosphorus, it’ll aid in the plant’s root development, flowering, and fruiting.
Or, if your soil has high nitrogen levels, the 13-13-13 fertilizer can help balance the nutrient levels.
On the flip side, if your plants require more nitrogen, which is typical of grass or leafy vegetables, the 10-10-10 fertilizer might be the better choice. This fertilizer has a higher concentration of nitrogen, which supports the development of leafy growth and vibrant green foliage, so it’s a solid choice.
Additionally, the 10-10-10 fertilizer is a strong pick for plants with a higher phosphorus tolerance, like established trees and shrubs.
Of course, you should use any fertilizer in moderation. Too much fertilizer can wreak havoc on your lawn and garden, creating nutrient imbalances and potentially harming the plant.
So, once you select the perfect fertilizer and are ready to apply it, carefully read the instructions and review application rates. In addition, it doesn’t hurt to consider getting a soil test to thoroughly evaluate your soil’s nutrient levels and deficiencies.
