I have complete faith that someone on here will be able to help me with this: I helped my next door neighbor renovate his front yard last fall. We slit-seeded with the same blend I used on my yard. It was a 80/20 KBG/Rye. The KBG was a mixture of midnight, nuglade, award, and bedazzled. Now his lawn looks like army fatigues! Early in the spring it was a dark uniform color, but now the spots that filled in are lighter green while his existing grass is much darker. I am a little embarrassed about it since he was hoping I could help. Questions: Do you think the new turf is lighter because it isn't mature and needs N to get dark or has a longer spring green-up? I checked NTEP and all the varieties of grass have a "dark green" color. Or, do you think its a soil issue? He is due for his second round of fert in a few weeks and I plan to let him use some of my LESCO 25-0-6. Maybe this will help since it was most uniform after I put down Dimension with 15%N. Thanks for any help you could give.
