Yard care and water savings Tips

Late fall or early winter are the best times to fertilize cool season grasses.  Since the majority of the lawns in North America are made from these grasses, like Bermuda and Bluegrass, it is a good bet your yard has a typical cool season blend.

Before the first freeze, give your lawn a thorough fertilizing to replace all of the nutrients that can be lost from the soil during the hot summer months.  Once the weather turns cold, the fertilizer will remain in the soil and feed your lawn's roots all winter long.

When spring comes, your lawn will be full of healthy lush, green grass that has been feeding on good fertilizer nutrients underneath the snow.
