Here is an interactive map from your UC Extension that recommends fertilizer applications in May, June, September, and October in your area, and using a complete fertilizer like the Target Specialty Pro 30-0-5 for your May and June applications.
Unfortunately, we do not have the spreader settings for the Target Specialty Pro 30 - 0 - 5 Fertilizer 50% Slow Release (Bermuda)specifically for the Scott’s Turf Builder Drop Spreader. We would recommend contacting Scott's at (888) 270-3714 to find out the proper setting. Another option is to calibrate your spreader yourself. We have a very helpful video on how to calibrate your own spreader linked below.
