Most lawn owners kill their crabgrass before they even see it. You do not treat a weed problem by fighting the plant, but by stopping the seed from ever waking up.
Success with Bermuda grass relies on this strategic silence. If you understand the timing of your local soil temperature, you have already won half the battle. Here are the Best Pre Emergents for Bermuda Grass to help you keep your turf thick and weed-free through the season.
Key Takeaways
- Match the active ingredient to the specific weeds that plagued your lawn during the previous growing season.
- Check the label for compatibility with your existing grass type to avoid chemical injury.
- Choose between granular or liquid concentrates based on your equipment and the size of your lawn.
- Calculate the square footage of your yard carefully to ensure you buy enough product for full coverage.
- Time your application to soil temperatures rather than the calendar to ensure the barrier is active at the right moment.

Frequently Asked Questions
Can I apply pre-emergent at the same time as grass seed?
You generally cannot do both. Pre-emergent herbicides prevent seeds from establishing roots, which means they will kill your new grass seed just as effectively as the weeds. Wait at least eight weeks after seeding before you apply a pre-emergent. If you are seeding in the spring, skip the pre-emergent entirely for that season.
How often should I reapply throughout the year?
Most homeowners get the best results with a split application strategy. You apply the first dose in early spring and a second dose in late summer or early fall. This two-step approach covers both the spring germination cycle and the fall weed season. Consistent timing is the secret to a weed-free lawn.
Will this product hurt my existing Bermuda grass?
Bermuda grass is tough and resilient. As long as you follow the label rates, these products will not damage established turf. Avoid applying these chemicals to newly sodded or recently sprigged Bermuda grass. The roots need time to mature before they can handle the chemical stress.
What happens if I miss the 55-degree window?
If you miss the initial soil temperature spike, you still have options. Use a product containing dithiopyr, which provides post-emergent control for very young crabgrass. It is better to apply late than not at all. Just accept that you might have to pull a few extra weeds by hand that managed to slip through the cracks.
Do I need to mow before applying the granules?
Mowing before application helps the granules reach the soil surface rather than getting caught on tall grass blades. Aim for a short, clean cut to ensure the product makes direct contact with the ground. Make sure the grass is dry before you mow. Wet grass can clump in your mower deck and make it difficult to get an even spread.
