Tips for Lawn Care Success
First, regular feedings help your lawn look it’s best and provide the nutrients it needs to withstand the stresses of weeds, weather and activity.

Secondly, after you mow leave the grass clippings on the lawn! This allows grass to use water more effectively. Finally, water; utilize nature’s sprinkler as much as possible. When you do have to water, do it between 6 and 10AM less water is lost to evaporation and more reaches the roots.
