After it has been mowed once or twice. Getter done. For the first application use a Natural Balance fertilizer with a ratio of 3-1-2 or 4-1-2. Go to the local Home Depot and locate a LESCO bag that has 15-5-10 or 20-5-10 in either a Purple on White or Green on White bag. Buy enough for one application.

Thanks, Texas-weed. The Home Depot stores in Maryland don't carry anything close to a 4-1-2 mix, so I ordered online Lesco Professional 16-4-8 fertilizer in a 50 lb bag for 10000 square feet. I only have about 4000 sf yard, so don't think I need the whole bag. Any problem with sealing the unused product, and saving it for next spring's first feeding?

Thanks for all your input on this forum. You have really helped me, and I'm sure many others!
