re: Deep green Bermuda (correct board)

Well I fertilized twice this year in March after a very low cut and again in the Beginning of May. I am just two years in after having the entire yard scraped, dirt brought in then leveled, and then I broadcasted seed. The yard looks good as I have tons of bermuda. Weeds are under control with regular use of MSMA and 2-4-D. But getting a deep dark green has alluded me. I am always trying to time spreading fertilizer with the rain. Not trying to water 3/4 of an acre.
