How often should I put corn gluten on my lawn?

As a gardening and landscaping expert, I highly recommend applying corn gluten to your lawn in late April or early May, and then again in late August or early September for three to four consecutive years. This timing is crucial because it aligns with the life cycle of weed seeds, effectively preventing them from sprouting and establishing themselves in your lawn.

Corn gluten is a pre-emergent weed killer, meaning it works by inhibiting the germination of weed seeds. However, it’s important to note that corn gluten also prevents grass seeds from sprouting, so it’s essential to consider this when applying the product.

I have found that applying corn gluten in late April or early May is ideal because it coincides with the beginning of the growing season for many weed species. By applying the product at this time, you can effectively disrupt their growth and prevent them from becoming a nuisance in your lawn.

Additionally, applying corn gluten in late August or early September is beneficial as it targets weed seeds that may have been deposited throughout the summer months. This second application helps to ensure that any remaining weed seeds are suppressed, giving your lawn a better chance to thrive.

It’s worth noting that corn gluten is not a quick-fix solution, and results may take time to become noticeable. This is why it is recommended to apply corn gluten for three to four consecutive years. By doing so, you can effectively reduce the weed seed bank in your lawn and create a healthier, weed-free environment for your grass to thrive.

It’s important to remember that corn gluten is a natural product, derived from corn, and it is safe to use around children and pets. However, it’s always a good idea to follow the instructions provided by the manufacturer and take necessary precautions when applying any herbicide.

In my personal experience, I have seen great results from using corn gluten as a pre-emergent weed control method. It not only helps to suppress weed growth but also adds organic matter to the soil, enriching its fertility. This can result in a luscious and healthy lawn over time.

To summarize, for the best results, I recommend applying corn gluten in late April or early May and again in late August or early September for three to four consecutive years. This will effectively prevent weed seeds from sprouting and establish a healthier, weed-free lawn. Remember to follow the instructions provided on the product packaging and consider the impact on grass seed germination when applying corn gluten.
