Mastering Pre-Emergent Herbicides for a Lush Lawn
As spring approaches, homeowners across the country find themselves grappling with the challenge of weed control. The common advice of applying pre-emergent herbicides can be confusing, especially when trying to ensure vibrant green grass like St. Augustine thrives. It's a hot topic in lawn care circles, discussed by experts like Dr. Shawn Askew, a turfgrass weed specialist at Virginia Tech.
Timing is Everything: When to Apply Pre-Emergents?
Applying pre-emergent herbicides at the right time is crucial for keeping weeds at bay. In warmer subtropical climates, such as those where St. Augustine grass grows, weed types and growth patterns differ significantly. Dr. Askew advises homeowners to apply pre-emergents like prodiamine or dithiopyr when soil temperatures are just at or rising above 55°F, typically between January 1 and mid-February.
"Many gardeners overlook the soil temperatures, which dictate when pre-emergents must be laid down," says Dr. Askew. "Miss this window, and you may end up dealing with pesky summer weeds like crabgrass instead." For winter weeds, a recommended time frame is around September 1 when soil temperatures dip below 70°F.
The Dos and Don'ts of Weed Control
When using any herbicides, it is important to adhere to some best practices. Dr. Askew emphasizes the necessity of watering the granules within a week of application if there has been no rainfall. This step activates the herbicide and helps it effectively prevent weeds from sprouting. Many homeowners mistakenly apply herbicides without enough moisture, leading to ineffective results.
Exploring Effective Lawn Care Solutions
For those still wrestling with weed problems or facing challenges with traditional methods, there are several strategies worth exploring. From innovative techniques such as thermal applications to organic options, varying approaches can provide tailored solutions that fit unique lawn environments.
