Turf Builder with Summer Guard

I have been hesitant to put out fertilizer this summer because of all the rain we have had. It could easily cause gray leaf spot and other diseases to develop in my lawn with heavy saturation. However, with a slight break in the rain, I think I will put out some Turf Builder with Summer Guard from Scotts on my lawn soon. My goal has been to fertilize about every 2 months or 5 times per year. I should be able to do this even with the weather setbacks this year.
