If you want to know whether corn gluten meal prevents weeds from growing or not, you have chosen the right article for it. Here I am going to share my knowledge on the matter of corn gluten meals working on weeds prevention or not. Hope your doubts will get cleared. So, our main concern is “Does corn gluten meal prevent weeds from growing?” Corn gluten meal will not kill mature weeds or plants. Corn gluten meal can kill weed seeds and can prevent weeds from growing. Killing weeds or preventing weeds growth also depends on how you use it and on what kind of weeds you use it. Let’s dig in a little deeper.
Corn gluten meal can prevent weeds growthBasically, the invention of corn gluten meal as a weeds preventer was an accident. Researchers at Lowa university invented that corn gluten meal can use as a weed preventer while doing their research on the disease. Later researchers at Oregon State University stated that corn gluten meal can’t prevent weeds from growing. So how does the corn gluten meal prevent weeds from growing? Let’s check. Mainly corn gluten meal is the by-product of corn wet milling. It is a natural pre-emergent herbicide in the replacement of chemical pre-emergent herbicides. According to the researchers at Lowa University, corn gluten meal can prevent the growth of grass and other seeds like crabgrass, chickweed, etc. But what about the research of Oregon University, right? It is important for you to know that corn gluten meal is only effective against seeds and not against the plants that are mature. Probably that’s why the researchers of Oregon University failed in their research. Cornmeal gluten having at least 60% the protein in it are more effective for weeds. So, if you use plain cornmeal products, it will not be effective. Weeds like crabgrass, purslane, foxtail, and pigweed can be killed by it. Along with mature plants, corn gluten meal cannot kill perennial weeds also, like, dandelions, quack grass, plantain, etc. They will come back again and again as their roots survive under the soil during the cold season. But corn gluten meal can kill the seeds from these weeds that they shed during summer and also with continuous use of corn gluten meal these weeds can be killed gradually.
Usage of corn gluten meal in your gardenNow you know that corn gluten meal is effective for preventing weeds growth. But to vanish the weeds from your garden, you also have to know the usage of it in your garden to get the best result. So let’s quickly know the procedure. Corn gluten meal will not do any harm to your existing plants so you can use it without any worries. Corn gluten meal comes both in granular and powdered forms. The granular one is easy to use but less effective. You have to take a certain amount of corn gluten meal for a specific coverage area and spread it on the area you need to cover, like 20 pounds of cornmeal for 1000 yards of lawn. After spreading you need to water the space lightly so that the oils can be activated. If the procedure is followed accordingly, the effects will last up to 5 to 6 weeks and after that, the corn gluten meal has to apply again in the same procedure. Before you apply the corn gluten meal, be sure to follow the following instructions:
- Follow the instructions on the package
- Apply before weeds start to grow
- The best time for applying is spring
Don’t confuse cornmeal and corn gluten mealMost people get confused between cornmeal and corn gluten meal. The cornmeal we eat and the corn gluten meal we use in the garden are two different things. The cornmeal we eat is a product that comes from ground-up corn kernels whereas the corn gluten meal is a by-product of the wet milling process of making cornmeal. Corn gluten meal contains high levels of protein, nitrogen, and oils.
