Pre-Emergent Weed Control and Fertilizer for Lawns
Synergy with Corn Gluten Meal is derived from corn gluten meal and is an all natural pre-emergent weed control and fertilizer for use in lawns. Corn gluten meal is the byproduct of the corn syrup production and has been used as a natural weed control for lawns for over 30 years.
Prior to the germination of weed seeds, if corn gluten meal is applied at 20 pounds per thousand square feet it will prevent new weed seeds from germinating properly. Synergy controls weed seeds and after the first application it is common to see around a 60% reduction in weeds in a lawn. If Synergy is applied both spring and fall for three or more consecutive years it is common to see up to a 95% reduction of weeds in a lawn.
Natural Weed Control for Grass
Synergy with corn gluten meal is one of the best organic fertilizers because it produces a long lasting green-up of grass. Synergy is a natural weed control made from corn and does not contain any synthetic chemicals. Synergy is a great option for those looking for a natural way to prevent weed seeds from germinating properly in your Boulder lawn.
We recommend spring applications of Synergy in March or early April and a fall application is also recommended in late September or October.
Lawns in the Boulder and Fort Collins area respond extremely well to Synergy applications because all the nitrogen is 100% organic and naturally slow release. This means the nitrogen in this organic fertilizer will only become available to the grass after the microbes in the soil decompose the corn gluten meal. This means the corn gluten meal will slowly feed the lawn and it is impossible to burn a lawn using a 100% slow release organic fertilizer. Since organic fertilizers are naturally slow release, the end result is a long lasting beautiful deep-dark green colored lawn.
Synergy with corn gluten meal is derived from only the highest quality natural ingredients and is considered non-toxic to people, pets, dogs, cats and children.
How effective is corn gluten meal on weeds?
Corn gluten meal prevents weed seeds from germinating properly. This means the first year the product is used on a lawn will only achieve about a 60% control rate on weeds. If corn gluten meal is applied to a lawn for consecutive years the effective weed control rate will increase each year.
Year 1: 60% control rate on weeds in a lawn
Year 2: 70% control rate on weeds in a lawn
Year 3: 80% control rate on weeds in a lawn
Year 4+: 90%+ control rate on weeds in a lawn
Note: Synergy with corn gluten meal for lawns is most effective as a pre-emergent organic weed control. If corn gluten meal is used on a regular basis it will build the soil and prevent weed seeds from germinating properly. The more consecutive years Synergy is applied to a lawn the more effectively it will prevent weeds from growing. Customers in the Boulder and Fort Collins areas that have been using Synergy with corn gluten meal on their lawns for 3 or more consecutive years have very few weeds in their lawn.
How does corn gluten meal kill weeds?
Corn gluten meal doesn’t really kill weeds, but it will prevent weed seeds from germinating properly. Shortly after weeds germinate in a lawn, the young weeds send out secondary feeder roots that are important for drawing vital nutrients from the soil. The corn gluten meal, which is a by-product of corn syrup production, damages the feeder roots of many young plants. The end result is that many of the weeds will germinate, but because the corn gluten meal damages the weed’s secondary feeder root, they will not develop into an adult weed. Corn gluten meal has been proven to control many types of weeds including: dandelions, crabgrass, thistle, clover, plantain, lamb’s ears, etc.

FAQ – Synergy with Corn Gluten Meal
When is the best time to apply corn gluten meal to a lawn?
Corn gluten meal applications on lawns work best if they are applied prior to weed seeds germinating. Spring applications in March or early April will prevent weed seeds from germinating properly and will fertilize the lawn. It is also important to apply corn gluten meal again in October as a winterizer for lawns. The more consistently corn gluten meal is applied to a lawn the better it will control weeds.
How does corn gluten meal work?
Shortly after a weed germinates from seed the young weed sends out a secondary feed root to uptake nutrients from the soil. The corn gluten meal damages the secondary feeder root and prevents the weed from developing from a young weed into an adult weed.
Is corn gluten meal safe for kids and pets?
Corn gluten meal is a food grade product and unless there is a concern of allergies it is considered to be non-toxic to people and pets. Corn gluten meal is a byproduct of the corn syrup production and is derived from corn. It is also found in many foods. Corn gluten meal is also used as a filler in dog foods and it is sometimes used in the making of beer.
That being said the Colorado Department of Agriculture will not allow any weed control to be called or labeled as safe. Therefore, we cannot say that corn gluten meal is safe for kids and pets, but we can say it is made of edible ingredients that are non-toxic to people and pets.
