When nightly temperatures drop to 65-70° F, preemergence herbicides should be used to suppress annual winter weeds such as annual bluegrass, henbit, and common chickweed, among others. Specifically, the days of August 15, September 15, and October 15, are advised in north Georgia, whereas the dates of September 1, 15, and October 15, are recommended in south Georgia.
In order to control summer weeds, use a spring pre-emergent between March 1 and March 15 each year. Apply when the soil temperature at 2′′ is 55 degrees or above, and when the soil temperature is increasing. It is important to remember that pre-emergents must be ″watered in″ by rain or irrigation within a week after application.
How do you apply a pre-emergent herbicide?
When applying a pre-emergent herbicide, be sure to wet it into the soil (or wait for rain) and let it dry before mowing again as usual. This is the most effective method. Pre-emergent herbicides should be used in the spring when soil temperatures have persisted at 55°F (12°C) for 2–3 days in order to achieve optimal efficacy.
When should I use pre-emergents?
Consider the following recommendations when deciding whether or not to apply pre-emergent pesticides: It is recommended that spring pre-emergents be sprayed after the soil temperature has been at or above 55°F (12°C) for 2–3 days. It is recommended that fall pre-emergents be administered when soil temperatures fall below 70 degrees Fahrenheit (21 degrees Celsius) for 2–3 days.
What happens if you apply pre-emergent too early?
When you disturb the soil, such as by digging or uprooting weeds/trees, it is possible that the effectiveness of your pre-emergent will be compromised in the digging area. It’s more likely that digging animals or your regular lawn maintenance may disrupt the pre-emergent barrier before it has a chance to operate if you apply it too soon after the emergence date.
When should you put down pre-emergent in Georgia?
When nighttime temperatures drop to 65-70° F, preemergence herbicides should be used to manage winter annual weeds such as annual bluegrass, henbit, and common chickweed, among others. The best time to visit is between August 15 and September 15 in north Georgia and between September 1 and 15 in south Georgia.
What month do you put down pre-emergent?
When should pre-emergent herbicides be applied? Pre-emergent herbicides should be used from August to November to prevent the growth of winter and autumn weeds such as bluegrass and prickly lettuce.

When should I apply crabgrass pre-emergent?
Early spring is the greatest time to apply crabgrass pre-emergent since the soil temperature has risen to around 55 degrees Fahrenheit. Apply the herbicide immediately before it is predicted to rain, but do not apply it to wet grass or weeds. Pre-emergent will be washed into the soil by rain, which will prevent crabgrass seeds from developing.
How soon can I overseed after pre-emergent?
So you should not overseed soon after spraying this herbicide; rather, you should wait at least 4 months between applications. You must do extensive preparation work if you must seed sooner than the recommended time to ensure that you have a quality seed bed that will not be affected by the pre-emergent herbicide.
Can I apply pre-emergent and fertilizer at the same time?
Because both pre-emergent and fertilizer must be soaked into the soil in order to be effective, they are a great combination. Using two different fertilizers at the same time and watering them in, you may simultaneously nourish your grass while also inhibiting the growth of weed seeds.
Can you overseed and use pre-emergent?
The good news for those who choose to go ahead and apply a pre-emergent in the autumn is that they will still have the option to overseed a bit in the spring, although the grass may not respond quite as strongly as it did in the fall.

Weed Control in the Pre-Emergency Situation
- To be on the safe side, don’t apply fertilizer if the soil temperature has been 50-55 degrees for five or more consecutive days.
- This is critical since it is at this point when 20 percent of the weed seed will begin to germinate
What color is pre-emergent?
