Agree with Michigan State University (Alma Mater), they found that heavy fall fertilization with quick-release nitrogen resulted in nitrate contamination of water at the 6 feet deep level, resulting from heavy rains and snow melt in the next few months.
So...I suggest a product high in slow release nitrogen. The Scotts would work, although their formula is seldom over 30 percent slow-release. You have to read the bag label carefully. It will say something like 30 percent nitrogen, of which 12 percent is slow release.
