Why is my lawn so yellow looking?
In spring, iron cholorosis, a deficiency of iron in the soil, is fairly common. But usually by the time summer arrives, it greens up thanks to decaying clippings and active biological activity in the soil, it tends to green up.
If you're still seeing yellowing at this time, your lawn may have a disease called take-all patch. Check the roots. If they're dark and rotted, and you can simply pull them up, this may be what you have. Take a sample to your Extension office or local nursery. Or check out Grow Green info online or pick up one their free Lawn Problems handouts at most nurseries. These Earth-Wise guides include pictures of lawn diseases, causes, and solutions.
