Fertilization is a crucial part of your lawn care routine in Tennessee, but a common question is whether you need to water it in after application. Well, it depends on the type of fertilizer used. Granular fertilizers typically need to be watered in afterward to activate them, and while liquid treatments usually don't, some products do. Watering your turf after fertilization helps the nutrients penetrate the soil more effectively, maximizing the benefits and ensuring your lawn gets the most out of the treatment. However, it's always best to talk with your lawn care provider to determine whether the fertilizer needs to be watered in or not.
Whether you need to water in the fertilizer depends on the type used.

Whether you need to water in the fertilizer depends on the type used. For example, granular fertilizers are typically always watered in after application to activate them. These treatments consist of small, solid granules that sit atop the soil, so watering them helps them break down and release their nutrients so they can start working.
On the other hand, liquid fertilizers usually don't need to be watered in, as they're absorbed quickly since they're already in liquid form. However, some products may require it. So, whether you need to water the fertilizer in depends on whether it's granular or liquid.
How does watering your lawn after fertilization help?
Watering your lawn after fertilization helps the nutrients penetrate the soil more effectively. When you do this, it drives the treatment into the ground, allowing it to reach the roots of your grass to maximize the benefits. On the other hand, if you don't water it in, the fertilizer might sit on top of the soil, and your lawn might not be able to reap the full benefits. So, watering your turf after fertilization is crucial to ensuring it gets the most out of the treatment.
Talk With Your Lawn Care Provider to Determine Whether the Fertilizer Needs to Be Watered In
While you may be tempted to water the fertilizer in after application, it's best to talk with your lawn care provider to determine whether it needs to be. After all, they're knowledgeable and experienced with these treatments, so they'll be able to tell you whether you should water or not. They'll also inform you if you need to wait or do it right away, as sometimes the fertilizer needs time to absorb into the soil before you water it to ensure it doesn't get washed away. By checking with your lawn care provider, you can rest assured that you're doing what's best for your turf and helping it get the most out of the fertilization treatment.
