Organic “weed and feed” for Lawns

Many gardeners are worried that the products being used to keep that beautiful lawn are, in fact, endangering the environment. With that in mind, then, there is a constant desire to use less damaging chemicals but, at the same time, retain a beautiful lawn. One solution may be corn gluten meal, a by-product of corn milling. It is quite high in nitrogen, which makes it a good fertilizer for grass, and it will prevent weed seeds from growing.

Corn gluten kills by drying up the baby sprouts as soon as the seed cracks open. However, it has no effect on perennial weeds or on annual weeds that are already growing. Furthermore, it must make good contact with the weed seeds in order to kill them — not a problem on bare soil but a tricky proposition if the grass is thick. It works best when the soil is warm, by which time many annual weeds have long since been up and about. And it lasts for only about six weeks, so you have to apply it regularly.

Corn gluten is a relatively benign fertilizer, and it can help control annual weeds if you use it faithfully, from spring to fall, for a couple of years. It is nontoxic and, in home-garden quantities, safe for the environment.

One of my favorite hand tools for “popping” those weeds out of the lawn

There is no panacea, however — you cannot go totally organic and control 100% of weeds in your lawn unless you have some handy tools for digging out the weeds. There are a lot of really good hand tools to help you tackle those weeds, though, and maybe a cleaner environment for our kids and grandkids is worth the extra effort.
