Pre-Emergent Herbicide Tips
Pick the Correct Pre-Emergent Herbicide
This is basic, but be sure to get the correct product. You will need a pre-emergent labeled to kill the weeds in your lawn, and it has to be labeled safe for your turf type. If you have any questions about which product is right for your lawn, Contact us. We are happy to help you find the correct herbicide.
Timing the Herbicide Application
Apply the herbicide at the appropriate rate and time of year for the weed you are targeting. Your local county extension service can give you specific recommendation for your area based on historical data from your county. If you need help with this process Contact us.
Watering in the Herbicide
Apply pre-emergent weed killer before expected rainfall or wash them into the soil with light watering immediately after application. This is recommended for liquid and granular pre-emergents. If the herbicide is not watered in within seven days poor results are likely.
Calibrate Your Spreader
calibrate your spreader if you are using a granular pre-emergent herbicide. You will get better and more consistent results when the product is applied accurately.
Don't Mow the Lawn
After you have applied the pre-emergent herbicide, don't mow the lawn until it has rained or you have watered in the herbicide. Mowing (especially when you bag the clippings) can remove a sizable amount of the herbicide if it has not yet been watered in.
Maintain Your Lawn
Keep your lawn healthy and vigorously growing. Proper maintenance should include mowing at the correct height and frequency, irrigating properly, appropriate fertilization for your turf type, and controlling pests. These steps can keep the grass healthy enough to compete with many common weeds.
