Answer: You didn't give us many clues to go on! Yellowing grass can be the result of over or under watering, lack of fertilization, poor drainage, or the beginnings of a fungal disease. If you submit another question with details about the care your lawn is receiving, amount of watering, feeding schedule, etc. we can give you some probable causes for the yellowing.
Hope to hear from you soon!
