Fast-Track Your Post-Emergent Herbicide Application

*This blog is based on current weather patterns we’re seeing in our Wisconsin, Illinois, and Minnesota markets* 

This spring has brought a slew of unpredictable weather, from fluctuating temperatures and unusually high amounts of rain. Homeowners and professionals alike are noticing the rapid growth of weeds in their turf and ornamental beds, which can be challenging to remedy. If you’re struggling with weed control due to the increased rainfall, it’s time to fast-track your post-emergent herbicide applications.

Understanding the Impact of Increased Rainfall

Rain may be crucial to keeping your lawns and gardens strong and healthy, but it also provides the moisture that weeds need to germinate and thrive, often outpacing your regular maintenance routines. Here’s what’s different this year:

  • Accelerated Weed Growth: Moist and cool soil creates the perfect environment for weeds to sprout rapidly.
  • Reduced Pre-Emergent Effectiveness: Consistent rainfall can wash away pre-emergent herbicides, reducing their effectiveness and allowing more weeds to emerge.
  • Increased Weed Competition: Weeds grow faster and more robustly, competing with your desirable plants and grasses for nutrients and space.

Given these challenges, adjusting the timing and frequency of your post-emergent herbicide applications is crucial helping your landscapes remain weed-free.
