The lawn shown has just recently begun turning a bit yellow. It is a mix of all Tall Turf Fescues and a very little mix annual rye for winter color. The lawn goes through a good fertilization and lime regiment and even had ironite sprayed on it in early fall. I feel like our weather lately has caused this yellowing. It has been rainy and cloudy. we have had a fair about of rain here. Should I apply some more fertilizer or iron or just leave it be?
