Question of the Week: March 1, 2018
“Neil, is it time to apply pre-emergent weedkiller to my lawn?”
If you’re anywhere in the southern two-thirds of Texas, yes, this is your time.
Photo: Crabgrass on left, grassburs (sandburs) on right both can be prevented by timely applications of pre-emergent weedkiller granules soon.
Here are the quick facts that cover pre-emergent applications in spring…
• Pre-emergent must be applied before weed seeds germinate (“emerge”). Apply now to prevent crabgrass, grassburs.
• Most common brands of pre-emergents: Team, Dimension, Halts.
• Timing South Texas: before March 5.
• Timing Central, North Central Texas: March 5-15.
• Timing far North Texas, Panhandle: March 15-25.
• Mow lawn (scalp) first, then apply granules.
• Water moderately after application to soak granules into top surface of soil. Do not try to time prior to rainfall, and do not apply if soil is saturated.
• Critical! Repeat application 90 days later for full season of prevention.
