I have great results with 10-10-10 same fertilizer i use in my vegetable garden. Its been a month now since i expanded my clover plot and i fertilized after i planted the clover seeds. I do this day before the rain arrives. I just checked on it today and i a happy camper. New seeds up 3/4"-1". last year plot ranging 6"-8". I only spread fertilizer in the spring mid april. After the 1st mowing that stuff really shoots up quick. I usually mow the plot in june. Best of luck to you.
