Know before you buy
Corn gluten meal acts as a natural pre-emergent by inhibiting the root development of weed seeds as they germinate. Because it targets seeds during the germination phase, it is effective against crabgrass and dandelions before they can establish themselves in your lawn.
No, this product should not be used on newly seeded areas. It is designed specifically for established lawns because its pre-emergent properties will prevent your new grass seeds from germinating as well.
Yes, it features a 9-0-0 N-P-K ratio, meaning it provides a significant boost of nitrogen to support green, healthy growth. It functions as both a weed preventer and a slow-release fertilizer in one application.
The ideal time to apply this product is in early spring, just before weed seeds begin to germinate. You should apply it before you see active weed growth to ensure the barrier is in place.
Because this product is made from 100% pure granulated corn gluten, it is a natural, organic solution. However, it is always best practice to keep pets and children off the lawn until the granules have been watered in and the area has dried.
No, this is a pre-emergent product, not a post-emergent herbicide. It will only prevent new weeds from establishing and will not kill weeds that have already sprouted.
