Corn gluten meal is an organic product that can be effectively used in lawns and gardens to prevent weeds and provide nutrients. To apply corn gluten meal, spread it evenly over the desired area, ensuring it is watered in well. This natural herbicide is best applied in early spring or fall to prevent weed seeds from germinating.
How Does Corn Gluten Meal Work?
Corn gluten meal functions as a pre-emergent herbicide, which means it prevents weed seeds from sprouting. It doesn’t kill existing weeds but inhibits the growth of new ones by drying out the seeds. Additionally, corn gluten meal is rich in nitrogen, providing a nutritional boost to your lawn or garden.
When to Apply Corn Gluten Meal?
Timing is crucial for the effective use of corn gluten meal. Here are some guidelines:
- Early Spring: Apply before weed seeds begin to germinate, typically when forsythia blooms.
- Late Summer/Early Fall: Use it again as a preventative measure against fall-germinating weeds.
For optimal results, apply corn gluten meal twice a year to maintain a weed-free lawn.
How to Apply Corn Gluten Meal to Lawns?
-
Calculate the Area: Determine the square footage of your lawn to know how much corn gluten meal you need. Generally, apply at a rate of 20 pounds per 1,000 square feet.
-
Spread Evenly: Use a broadcast spreader to distribute the corn gluten meal uniformly across the lawn.
-
Water In: Lightly water the area to activate the meal, but avoid overwatering as it can wash away the product.
-
Avoid Disturbance: Do not disturb the soil after application to ensure it forms a barrier on the surface.
