Using Cornmeal To Kill Weeds and Ants

Cornmeal gluten is the by-product of corn wet milling. It is used to feed cattle, fish, dogs, and poultry. Cornmeal is known as a natural substitute for chemical pre-emergent herbicides.

Using cornmeal as weed killer is a great way to eradicate weeds without the threat of toxic chemicals. Iowa State University discovered by accident that cornmeal acts as an herbicide while they were doing disease research. They saw that cornmeal kept grass and other seeds, such as crabgrass, dandelions and chickweed, from sprouting.

NOTE: It is important to note that cornmeal is only effective against seeds, not plants that are mature.This also means you need to get it down BEFORE the seeds sprout, so we're going to spread it here in Central Virginia the first week of March.

Here's a few other ideas:

Using Salt to Kill Weeds 
Gardening With Vinegar
Using Sugar to Kill Weeds in Lawn

Editor's Note: I have used table salt purchases in 25 lb. bags for areas where we don't want things to grow (under the gravel in the driveway mainly), and it works! If there's not nearby vegetation to creep in, it's lasted for three years. Down by the street in the easement area, the weeds are quicker to grow into the graveled driveway, so it only lasts a year there.

We have also used vinegar in a garden sprayer which was much quicker than sprinkling salt and then adding water to it.  You could enjoy a nice time in the rain if you put the salt down while the rain could water it in, but my husband likes the idea of putting it in a "tool" and spraying.  He adds a few drops of Sunshine Concentrate since soap was recommended in one recipe to help the vinegar stick to the plants and roots until it dies off in a few days.
