Spring is the time of year when most homeowners start thinking about their lawns. One of the most important things to consider is fertilizer. Fertilizing your lawn in the spring can help it grow strong and healthy throughout the summer. But with so many different fertilizer options available, it can be hard to know which one is best. In this article, we’ll take a look at the best spring lawn fertilizer numbers for 2023.

What Are Fertilizer Numbers?

Before we dive into the best fertilizer numbers for spring, it’s important to understand what those numbers mean. Fertilizer is typically labeled with three numbers, such as 10-10-10 or 20-5-10. These numbers represent the percentage of nitrogen, phosphorus, and potassium in the fertilizer. Nitrogen promotes leaf growth, phosphorus promotes root growth, and potassium promotes overall plant health.

Best Fertilizer Numbers for Spring

When it comes to spring lawn fertilizer, there are a few different numbers to consider. For the best results, look for a fertilizer with a higher nitrogen content. A ratio of 4-1-2 or 3-1-2 is ideal for most lawns. This will promote strong leaf growth and help your lawn look green and lush.

Benefits of a Higher Nitrogen Content

In addition to promoting leaf growth, a higher nitrogen content can also help your lawn recover from winter damage. It can also help your lawn resist pests and disease throughout the summer. However, be careful not to overdo it with nitrogen. Too much can actually harm your lawn and cause it to grow too quickly.

Other Considerations

In addition to the fertilizer numbers, there are a few other things to consider when choosing a spring lawn fertilizer. Look for a slow-release fertilizer, which will provide a steady supply of nutrients to your lawn over time. You should also consider the size of your lawn and the type of grass you have. Some grasses may require a different fertilizer ratio.

Application Tips

Once you’ve chosen your fertilizer, it’s important to apply it correctly. Follow the manufacturer’s instructions for the best results. Typically, you’ll want to apply fertilizer in the spring when your lawn is just starting to grow. Be sure to water your lawn after applying fertilizer to help it absorb the nutrients.


Choosing the right spring lawn fertilizer can help your lawn grow strong and healthy throughout the summer. Look for a fertilizer with a higher nitrogen content and a slow-release formula for the best results. Be sure to follow the manufacturer’s instructions and water your lawn after applying fertilizer. With the right fertilizer numbers and application techniques, your lawn will be the envy of the neighborhood in no time.
