Understanding Pre-Emergent Herbicides
Pre-emergent herbicides work by creating a chemical barrier in the soil that prevents weed seeds from germinating. LESCO products, such as Stonewall and Dimension, are formulated with specific active ingredients that target a broad range of weeds, including crabgrass, foxtail, and goosegrass. The effectiveness of these products largely depends on timing and application methods.
Importance of Application Timing
Timing is critical when applying pre-emergent herbicides. The ideal time to apply LESCO’s products is just before the soil temperature reaches 50-55 degrees Fahrenheit for five consecutive days. This temperature range signifies the beginning of the germination process for many common weeds. If applied at the right time, LESCO pre-emergent solutions can effectively prevent up to 80% of weed seeds from sprouting.
Key Temperature Indicators
- 50-55°F: 20% of weed seeds begin germinating.
- 60-70°F: The majority (80%) of crabgrass and similar weeds germinate.
To track soil temperatures in your area, utilize resources like the USDA’s CRN/SCAN Soil Map or Greencast’s Soil Temperature Map. Regularly checking soil temperatures ensures timely and effective application.
Types of LESCO Pre-Emergent Products
LESCO offers a variety of pre-emergent products, each designed for specific applications and weed types.
LESCO Stonewall 0-0-7
Stonewall is a granular pre-emergent herbicide that effectively controls grassy and broadleaf weeds. It is especially effective against crabgrass and is suitable for residential lawns, gardens, and landscapes. This product provides both weed prevention and essential nutrients for the soil, promoting overall plant health.
LESCO Dimension 19-0-7
Dimension is another robust option that not only prevents the growth of weeds but also fertilizes the lawn simultaneously.

Application Techniques
Proper application is essential for maximizing the effectiveness of LESCO pre-emergent products. Here are some best practices:
Using a Broadcast Spreader
To ensure even distribution of the herbicide, use a broadcast spreader. This equipment allows for uniform application across the lawn, preventing streaks or missed spots. Follow the manufacturer’s guidelines for the correct spreader settings.
Water Activation
After applying the herbicide, it is crucial to water the area lightly. This helps activate the chemical barrier by allowing it to penetrate the soil. Aim for about 0.5 inches of water within 24 hours of application to ensure optimal performance.
Monitoring Weather Conditions
Weather can significantly impact soil temperatures and the effectiveness of pre-emergent herbicides. Rain, sun exposure, and temperature fluctuations can all affect the timing of your application. It’s best to monitor local weather patterns and adjust your schedule accordingly.
