CORN GLUTEN MEAL
All it takes is a little bit of rain, or some moisture, and bang, the weeds are here.
Until recently, most pre-emergence weed killers have been chemically produced, like Ronstar and others, but now we have a great organic alternative and that is Corn Gluten Meal.
Corn weed blocker is made from corn gluten. It is a 100% natural weed suppressor and slow release granular nitrogen fertilizer.
Corn gluten is a pre-emergence herbicide, so it works by inhibiting the development of small feeder roots. It does well against germinating seeds only, it won't affect established plants.
It can be applied in and around lawns, bedding plants, trees, shrubs, & vegetables.
Corn gluten, like any pre-emergence, works best when applied to bare ground before any weeds sprout. So before application, clear any and all weeds from the area, apply, and then water in.
