The most important thing you can do for a lawn is to provide it with
proper nutrition. A well-fed, healthy lawn has a better root system to
combat heat, cold, drought, mowing, foot traffic and other stresses. A
quality, granular, controlled-release fertilizer allows grass plants to
grow evenly, without starvation periods or heavy growth spurts.
Controlled, even growth also minimizes grass clippings.     

Lawns wake up hungry from the winter months. A spring feeding
strengthens roots and gets lawns off to a good start before the heavy
growing season. In most regions, it is wise to apply a combination
fertilizer with a pre-emergent to control weeds.

Summer and fall fertilizing are also equally important to keep nutrient levels where they should be and to keep weed growth to a minimum.

A healthy lawn and landscape keep property values up and your
neighborhood beautiful.
