There are plenty of good reasons to renovate, says Dennis Williamson, technology development manager for the southern United States region for Monsanto.Perhaps the old turf is no longer aesthetically pleasing or the area's being converted to a new use or it's time to install a new and improved cultivar.Whatever the reason, Williamson says the initial planning is important.

"I would start by figuring out when I plan to use the turfgrass again, and then work back from there to determine a schedule for applying the herbicides," Williamson says.

"Certainty can be used in most warm-season turf grasses and unlike many other herbicides, Certainty is labeled for post-directed sprays around woody ornamentals," said Dennis Williamson, technical development manager for Monsanto's Southern U.S. Industrial, Turf and Ornamental business group.
