Each lawn is unique, so fertilizing cycles vary from 4 to 8 weeks during the March through November growing season. To determine your cycle, mark a calendar when you fertilize your lawn; then wait until the color starts to fade and note that date. Subtract a week and you have your fertilizing cycle. Repeat throughout the growing season.
Use a granular, well-balanced fertilizer (available from Western Turf such as 16-6-8 or 16-16-16).
Avoid ammonium sulfate (21-0-0) alone -- it will green your lawn but it won't nourish it.
The important point is not what you plant but how you water and maintain it. Plants don't waste water; man does!
