• Reapplication: CGM’s effectiveness lasts for about 4-6 weeks, so you may need to reapply throughout the growing season to maintain weed control.
• Cost: CGM can be more expensive than chemical herbicides or regular cornmeal, so consider this when planning your garden budget.
• Selective Use: Because CGM can inhibit the germination of all seeds, use it with caution around areas where you’ve planted seeds you wish to grow.

Using corn gluten meal as a natural weed suppressant in your garden is an innovative and organic approach to managing unwanted plants. By understanding the proper application and timing, gardeners can effectively use CGM to maintain weed-free beds without resorting to chemical herbicides, benefiting both the environment and the health of their garden ecosystem. As with any gardening technique, observing and adapting to how it works in your specific garden conditions is key to success.
