Synergy - FAQs

Q. What is corn gluten meal?
A. Corn gluten meal is a by-product of the corn syrup production process. It is typically used as a food source for cattle and dogs.

Q. Why is corn gluten meal important?
A. Synergy is 79% corn gluten meal and 21% other organic fertilizers. It is an organic pre-emergent weed control (will prevent the germination of weeds) and an organic fertilizer.

Q. How is it applied?
A. Synergy is a granular applied via a broadcast spreader. Most spreaders are not capable of spreading a heavy enough rate to get 20 lbs per 1000 sq ft. We use Earthway commercial spreaders at a full open rate to get to the proper application rates.

Q. Is it toxic for dogs?
A. Synergy is considered edible and many dog foods contain corn gluten meal. Only dogs that have a gluten allergy may have issues with Synergy.

Q. When should Synergy be applied?
A. For the highest effectiveness in controlling weed germination, we recommend applications in spring and fall. The spring application will fertilize your lawn while preventing the germination of weed seeds. The spring application needs to be applied prior to the germination of weed seeds (March 1st through March 31st is ideal). The fall application will winterize your lawn as it develops a corn gluten meal concentration in the soil. If you choose to have a fall application, we recommend you then have Synergy applied again in the spring.

Fall and spring = 60%-80% effectiveness rate in controlling weed seed germination.
Spring only = 40%-60% effectiveness rate in controlling weed seed germination.

Q. How effective is corn gluten meal in controlling weeds?

First Year = 60% control rate
Second Year = 70% control rate
Third Year = 80% control rate
Fourth Year = 90%+ control rate

Q. If Synergy is 100% organic why is there a yellow pesticide flag on my lawn?
A. It is a legal requirement to post a pesticide application flag even though this product is 100% organic as a requirement of the Department of Agriculture. Anything that claims to control weeds must be flagged using a pesticide application marker.

Q. Synergy didn't work very well on the dandelions, why not?
A. Dandelions are a biennial plants meaning they germinate from seed the first year and then for one to two more years they will germinate from their root system. Your lawn naturally has dandelions at different stages of growth so annual applications of Synergy are necessary because Synergy only controls weeds germinating from seed. This means the first application of Synergy won't control the dandelions that are germinating from an established root system. Patience is a requirement for corn gluten meal; however, it is extremely effective if used regularly over a 2-3 year time span.

Q. Will this product kill my weeds?
A. No. It will prevent many weed seeds from germinating and developing properly. This may include grass seeds so if you are planting grass within the next 2-4 weeks we don’t recommend applying this product.

Q. You applied this product and there are weeds germinating, will you spray them with a post-emergent product for free?
A. No. This product is an organic pre-emergent and will not prevent all weeds from germinating properly, just weeds germinating from seed. In conjunction with One Earth Weed Control on a full season program you will see a mostly weed free lawn in one year (with proper cultural practices like mowing and watering). Instant gratification is not something that Synergy can produce. If you are expecting a weed free lawn after one application you will need to understand that organic lawn care is a process, but if you continue to be patient and diligent then the program will work very well.

Q. Why is Synergy more expensive than chemical fertilizers?
A. Synergy is applied at 20 lbs per 1000 square feet. Most chemical fertilizer products are only applied at a 2-4 lb per 1000 square feet, so more product is required when applying Synergy.

Q. Will Synergy burn the lawn if over applied?
A. No. The fertilizer in Synergy is 100% organic and it will not burn a lawn if over applied. The nitrogen in the Synergy is naturally slow release and it requires microbial activity to break it down before it will become available to the plant for uptake.
