For Healthy Grass, Adjust Your Soil pH
Soil pH (acidity level) is very important, and just because your dirt looks rich and black doesn’t mean it’s the right pH for grass. Take samples around the yard and get them tested. If the pH is too low (acidic) or too high (alkaline), the grass isn’t happy to be there. But you can fix the problem by adding lime to raise the pH or iron to lower it. Most grasses prefer a pH of 6.0 to 7.2.
Note: Lawn and garden centers sell do-it-yourself pH testers; more accurate tests can be performed by extension services.

Healthy Grass Is the Best Weed Preventer
Lawns that are nutrient-stressed are a breeding ground for weeds, so the best defense is a healthy lawn. Test the soil to see what type and quantity of fertilizer is needed to help your lawn. Proper fertilization improves lawn health, so grass can compete better and crowd out weeds—without a lot of weed killer.

The Best Lawn Advice is Locally Grown
One-size-fits-all doesn’t work for fertilizer, weed killer and grass seed, even though that’s what the chain stores sell. Lawn products that work great in Georgia clay may not be good for Kansas or Oregon. The best way to find out about growing conditions in your area and what to put on your lawn, and when, is to talk to a local garden center or your agricultural extension service.
