Portions of my lawn remain yellow even though I have applied a fertilizer. What should I do to regreen my grass?
Lawns may develop iron deficiencies during late winter and early spring. The yellowing often occurs when the turf grows in soils with a high pH. Also when the soils are cool, the iron is less likely to be available in sufficient quantities to supply the needs of the growing grass. Giving the grass a general feeding can make the problem worse. The major nutrients in the fertilizer push growth without having adequate iron available, and the grass gets more yellow. Use an iron-only product to renew the green. You can obtain granular or liquid formulations from your local garden center. Also have the soil acidity checked, and adjust the pH if needed.
