If you’re looking for greener grass without using harsh chemical on your lawn, Better Homes and Garden says to consider corn gluten meal. It’s a byproduct of corn milling, and it’s a natural herbicide that you can use as a crabgrass preventer on lawns.
When it comes to preventing weeds, timing is the key. Apply corn gluten products right before weed seeds sprout. In most areas, that’s when forsythia blooms begin to drop.
