First, I suggest you read our on line FERTILIZER CONTROL article which explains all you really need to know about how to keep your grass looking great.

Second, be sure to check the PH as explained in the above article; if the PH is wrong, you won't stand a chance at getting a nice yard. SOIL PH CONTROL is one of the biggest reasons people fail in getting the results they want when it comes to their yard.

Lastly, understand that every yard is different and though they all need nitrogen, the amount and best time to apply it are things that are only learned over time. By working on your yard year in and year out, you should be able to figure out a schedule that will include PH control, insect control and fungus control. By keeping these in check you should be able to regulate the fertilizer and grow nice green grass. But this will take some time. In most cases, it will take a good 2 years for people to get the end result where they want it and ultimately will depend on how much time you devote and how much water you have available. Unlimited chemicals and time won't help if you don't have water!!
