When to Apply Corn Gluten

When and how should I apply corn gluten to my lawn for the best weed control?

The University of Iowa found corn gluten is effective at preventing many seeds, including some weeds, from germinating. For best results apply corn gluten in late April or early May and again in late August or early September for three to four consecutive years. Keep in mind this product like other pre-emergent weed killers prevents grass as well as weed seeds from sprouting. You will not be able to reseed you lawn the same season you use this product. Apply 20 pounds of corn gluten per thousand square feet. Water lightly to move the gluten into the soil and get it started working.
