The Difference Between Pre-Emergent & Post-Emergent Weed Control

If you’ve ever looked out at your lawn and spotted weeds popping up where you know grass should be, you’re not alone. At Farison Lawn Care, we know a lot of homeowners want to learn how to tackle crabgrass, and one of the biggest ways to get started is understanding the difference between pre-emergent crabgrass control and post-emergent treatments.

Let’s walk through what those terms really mean, and how they work together to keep your lawn looking its best.

What Is Pre-Emergent Weed Control?

Pre-emergent weed control is your lawn’s first line of defense. It targets crabgrass seeds in the soil before they have a chance to germinate, so you’re stopping the problem before it even starts.

This is especially helpful for annual weeds like crabgrass, which tend to appear in the spring and spread rapidly once summer arrives. For the best results, crabgrass control for lawns should occur in early spring. That timing is super important, and that’s also precisely where we come in.

Our team at Farison times our pre-emergent applications with the seasons as part of our lawn care program. You never have to worry about missing the window for pre-emergent when you work with us.

What Is Post-Emergent Weed Control?

Once weeds are already growing, post-emergents come into play. These products work on weeds that you can already see, attacking both the leaves and the root system to shut them down completely.

Post-emergents can be applied throughout the growing season to treat weeds in both your lawn and landscape beds.

So… Which One Do You Need?

Honestly? Probably both. A smart lawn care plan begins with pre-emergent weed control to prevent crabgrass weeds before they emerge. Then, we use post-emergents for weeds that are already growing in.

If you’ve been fighting off crabgrass and other weeds for years, combining the two is your best bet. As a local crabgrass control company, we build custom programs that match your lawn’s needs—so you don’t have to play the guessing game.
