Everyday Usage of Pre Emergent for Bermuda Grass
Pre-emergent herbicides are a fundamental tool for Bermuda grass lawn owners aiming to achieve a lush, weed-free appearance season after season. They work by creating a barrier in the soil that stops weed seeds from developing into mature plants, effectively preventing weeds before they even emerge. For Bermuda grass, which is valued for its density and vibrant color but can be overtaken by aggressive weeds like crabgrass and Poa annua, timely use of a pre-emergent is crucial.
Typical Use Scenarios
- Spring: Apply when soil temperatures consistently reach 55°F (preferably before the first flush of weeds). This stops summer annuals like crabgrass and goosegrass.
- Fall: Apply when night temperatures are steady around 55–60°F. This prevents winter annual weeds like Poa annua (annual bluegrass), chickweed, and henbit, which can gain a foothold during Bermuda’s dormancy.
- Established Lawns: Only use pre-emergents on mature Bermuda lawns (at least one year old).
- Targeted Weed Prevention: Select pre-emergents targeting the weeds commonly seen in your region (consult product label for spectrum).
Steps for Application
- Mow the lawn if needed, prior to application.
- Apply the pre-emergent—granular with a spreader or liquid with a tank sprayer.
- Water in the product as soon as possible (unless rain is imminent) to activate the barrier.
- Avoid disturbing the soil (aeration, dethatching) immediately after applying, as this can break the barrier.
Benefits of Using Pre Emergent on Bermuda Grass
Using a pre-emergent herbicide delivers tangible results for Bermuda lawns:
- Proactive Weed Control: Stops weeds before they start, reducing the need for back-breaking hand weeding or repeated post-emergent sprays.
- Promotes Lawn Health: Less weed competition for water, sunlight, and nutrients means stronger, greener Bermuda grass.
- Reduces Chemical Use: Fewer weeds emerging results in less need for post-emergent, potentially harsher, chemicals throughout the season.
- Aesthetic Appeal: Maintains a uniform, weed-free appearance that heightens curb appeal and overall enjoyment of your lawn.
- Saves Time and Money: A well-timed application prevents many future problems, reducing maintenance costs and labor.
How to Choose the Right Pre Emergent for Bermuda Grass
Selecting the ideal pre-emergent for your Bermuda lawn involves several factors:
1. Active Ingredient Profile
- Prodiamine (Barricade DG, Quali-Pro, Yard Mastery, LESCO Stonewall): Long residual, broad spectrum, safe for Bermuda grass, widely favored for both spring and fall use.
- Dithiopyr (Dimension): Dual pre- and early post-emergent activity on crabgrass, effective against a wide range of grassy/broadleaf weeds, popular among professionals.
- Pendimethalin (Scotts Halts, WeedEx): Cost-effective and easy for home use; good for annual grassy weeds, though some studies note it may briefly suppress Bermuda vigor.
- Indaziflam (Specticle Flo/Specticle G): Premium, long-lasting control (especially for Poa annua), but more expensive and with strict reseeding restrictions.
- Mesotrione (Tenacity, select products): Unique, works on certain troublesome broadleaf weeds, but use with care and only when labeled for Bermuda.
2. Formulation (Granular vs. Liquid)
- Granular: Best for easier, even coverage over large areas using a broadcast spreader. Suited to DIYers.
- Liquid (Water Dispersible Granule or Concentrate): Allows tank-mixing with fertilizers/pesticides, often enables even coverage on complex or sloped lawns. Suited to experienced users.
3. Seasonal Target
- Spring: Focus on crabgrass/goosegrass and other summer annuals.
- Fall: Target Poa annua, chickweed, henbit, and other winter annuals.
4. Coverage Area and Cost
- Calculate total square footage and compare product labels for coverage. Larger containers are more economical for big lawns.
5. Intended Use
- Residential Lawns: Double-check for residential safety—most major brands are labeled as safe for home lawns.
- Overseeding Plans: If you plan to overseed Bermuda with rye or annual grass, note that most pre-emergents will inhibit germination of desired grass seed—check reseeding intervals.
6. Compatibility with Other Inputs
- Many products can be tank-mixed with fertilizers or other lawn chemicals, but always confirm compatibility and label guidance.
User Tips and Best Practices
Achieving optimal pre-emergent results hinges on smart product selection and proper timing:
Timing and Temperature
- Spring: Monitor soil temps, not just calendar dates. Apply when soils reach 55°F for several consecutive days.
- Fall: Target application when nighttime lows hit 55–60°F for four consecutive nights.
- Rain/Irrigation: Always water in granules (within 2–3 days). If using liquid, light watering may be needed (follow label). Avoid application before heavy rains to prevent runoff.
Application Methods
- Equipment: Use a calibrated broadcast spreader for granular products; for liquids, use a clean, dedicated lawn sprayer.
- Complete Coverage: Pre-emergents must be evenly applied to the full lawn—skip areas become weed “breakouts.”
- Overlap and Label Rates: Avoid double-overlappings as it may damage turf. Stick to recommended rates—“more is not better.”
Safety and Environmental Care
- Avoid on New Sod/Seedlings: Never apply to Bermuda lawns under a year old—wait until fully established.
- Wait Before Seeding: Expect to wait 3–6 months after pre-emergent application before any seeding or overseed (check your product’s label).
- Protect Non-Target Plants: Avoid drift onto flower or vegetable beds. Some active ingredients can damage ornamentals.
Rotating Products
- Occasionally rotate between active ingredients (e.g., prodiamine in spring, dithiopyr in fall) to manage resistance and maintain effectiveness.

FAQ
-
What is pre-emergent and how does it work?
Pre-emergent is a type of herbicide applied to the lawn before weeds emerge. It creates a chemical barrier in the soil, preventing root development in weed seeds as they germinate. This stops weeds before they grow, reducing the need for later treatments. -
When should I apply pre-emergent to Bermuda grass?
Apply pre-emergent twice a year: in early spring (before soil temps reach 55°F for a few consecutive days) and in early fall (as nights stabilize at 55–60°F). Exact timing may shift based on your local climate and weather. -
Can I use any pre-emergent on Bermuda grass?
No. Only use pre-emergents labeled as safe for Bermuda grass. Some herbicides, like oxadiazon, are not intended for residential lawns and may damage Bermuda grass if misused. -
Will pre-emergent prevent all types of weeds?
Pre-emergent is highly effective on annual weeds, including crabgrass, Poa annua, chickweed, and henbit. It’s less effective on perennial weeds or weeds that have already sprouted. For existing weeds, use a post-emergent herbicide. -
Should I apply pre-emergent before or after seeding?
Always apply pre-emergent well before seeding or at least several months after. Pre-emergent will prevent new grass seeds from germinating as well as weeds. Wait the specified reseeding interval listed on your pre-emergent’s label. -
Do I need to water my lawn after applying pre-emergent?
Yes. Watering is necessary to move the product into the soil where it can form the protective barrier needed to stop weeds. Water in the product within a day or two of applying. -
What happens if I miss the application window?
If you apply pre-emergent after weed seeds have already germinated, the product loses much of its effectiveness. It’s still better than nothing, but you may need post-emergent herbicides for weeds that have already broken through the soil. -
Is granular or liquid pre-emergent better?
Both forms are effective. Granular is easier for most homeowners to apply evenly with a broadcast spreader. Liquid forms (including water-dispersible granules) can provide more uniform coverage, especially for complex lawns, but require a sprayer and careful mixing. -
Are pre-emergent herbicides harmful to pets or children?
Once dry and watered in, most residential pre-emergents are safe for kids and pets. Keep them off the treated area until the product has dried, and follow all product-specific safety instructions. -
How long does pre-emergent protection last and how often should I reapply?
Most products protect your Bermuda lawn for 3–6 months per application. The pre-emergent barrier breaks down over time from weather and mowing. For full-season control, repeat the application twice a year in early spring and early fall according to label recommendations.
