TechNotes Tips

The heavy rains through most of the Midwest the last 30 days has caused saturated soil conditions. These wet conditions along with favorable temperaturesfor shoot growth have disrupted mowing schedules causing scalping and wear damage to the turf. Scalping is the removal of too much leaf tissue resulting in yellowing of the turf. If you are unable to mow a lawn frequent enough to prevent scalping, raise the height of cut. Raising the height of cut will result in less tissue being removed with the mowing which should reduce the potential for, and the severity of scalping. Once a frequent mowing schedule is achieved gradually reducing the height back to the original height can be accomplished.

Lawns that are wet, are susceptible to mower damage from turning or spinning of the tires. Slow the mower down when turning to reduce the “sliding” of the mower. In shaded areas, be especially careful of tire spinning and wear. Generally, turfgrass plants in shade are more susceptible to wear damage Current and the previous year’s soil temperatures at two depths.
