Homeowner lawn care tips
Crabgrass control -
Late February to mid-March is the best time to apply a preemergence herbicide for crabgrass control in Arkansas. Although we are nearing the end of this window, it’s probably not too late to apply preemergence herbicides. To be effective, preemergence herbicides must be applied before weeds emerge. Applying too late may miss the early part of the germination window of crabgrass. Warm-season lawns such as bermudagrass and zoysiagrass should be treated with a preemergence herbicide that does not contain fertilizer. Tall fescue lawns can be treated with a preemergence herbicide with fertilizer. These herbicides should be lightly watered into the lawn for best results. As always, read the label. For more information about weed control in home lawns please check out the linked publication :

Research update
Recovery of Bermudagrass Varieties from Divot Injury -
Intensively used turf areas in the southern United States are commonly established to bermudagrass, partly due to its good recuperative potential. However, little scientific data is available regarding recuperative differences among bermudagrass varieties. The objective of this research was to quantify differences in injury recovery among the forty-eight bermudagrass entries in the 2002 National Bermudagrass Test of the National Turfgrass Evaluation Program.
