Natural Weed Control
Weeds in Hardscape
To kill weeds that come up in the driveway or patio, simply pour boiling water or salty water on them, or pour on white vinegar.
Weeds in the Garden
To keep your garden virtually free of weeds and grass, put down a weed barrier mat. Place your plants on top until you find a pattern that you like, then make a cut in the fabric so you can plant each one. The fabric between plants can be hidden with mulch or bark.
Weeds in the Lawn
Get rid of dandelions while they are still pretty yellow flowers. They turn into white puffballs (that were so much fun to blow when you were a kid), which contain the seeds of hundreds more dandelions. A quick fix is to cut them down with a lawnmower or weedwhacker. Better still is to dig each one up roots and all.
Put corn gluten (marketed as Original WOW!®) on your lawn, and absolutely no weed seeds will grow. It will also keep new grass seed from growing, so put it down at least six weeks before you seeding any bare spots. An added benefit of corn gluten is that it is very high in nitrogen, which is the food that lawns crave the most.
