I live in Fort Lauderdale FL, have St Augustine Floratam grass. The lawn is 40 years old but in good condition. What type fertilizer would you recommend for this time of year (ie About 30 nitrogen or closer to 20)? The greenies in our area are trying to outlaw phosphorus...do you need it in the lawn fertilizer?

Phosphorus helps stem growth and flowering so it is not essential to turfgrass, but it is one of the major nutrients found in most fertilizer blends. Floratam thrives on nitrogen so that should be the highest number on the package. You can feed now with a 12-3-8, or 16-4-8, or similar fertilizer. In the fall you'll want to change to a more equal ratio of NPK such as a 6-6-6. Best wishes with your lawn.
