Combating Summer Weeds

Your customers’ summer grass is coming in. The fertilizer you spread is creating a lush green lawn and everything is nearly perfect, if it wasn’t for those pesky weeds. No matter where you are in the country you have summer weeds. While there are several species of summer weeds, two types in particular are prevalent in almost every region in the country: nutsedge and crabgrass.

To help you arm yourself against these stubborn weeds, Andy Keeton, Ewing’s National Turf Products Manager, shares a few tips and tools.


When it comes to nutsedge, Sedgehammer Plus Turf Herbicide is effective against most varieties, especially yellow and purple nutsedge weeds. It can also help manage certain broadleaf weeds and kyllinga, without damaging surrounding grass, shrubs or trees.

For use, spray the target weeds thoroughly, making sure to wet the entire leaf surface of the undesirable plants. However, avoid applying an herbicide when the turfgrass or nutsedge is under stress, such as excessive heat, because this could result in turf injury or poor nutsedge control.

“For optimum results, don’t mow the turf for two days before or two days after application,” shared Keeton. “Also, avoid irrigation or rainfall for at least four hours after.”

Developed to control crabgrass, BASF’s Drive XLR8 Herbicide provides fast, effective weed management and can be used within an hour before rainfall. Drive XLR8 is most effective in warmer climates, with temperatures above 80 degrees Fahrenheit.

Just like with nutsedge, Keeton says to avoid mowing two days before and after application. He also suggests using a methylated seed oil (MSO) to help with consistency.

Regardless of which product you use for combating weeds, Keeton reminds users “The label is the law. It is actually a violation of federal law to use this products in a manner inconsistent with its labeling, so be sure to read and follow all instructions provided by the manufacturer.”
