    5. TURF TIPS.

    A. PALE GREEN TURF. Joe Rimelspach noted that mysterious chlorotic patches
    of turfgrass have once again returned to lawns and fields in rain-soaked
    Ohio. Certain cultivars of Kentucky bluegrass develop yellowish, irregular
    patches and streaks during periods of continual rainfall, cloud cover, and
    warm temperatures. The cause is still unknown, however turfgrass scientists
    speculate that it is a physiological response to slow growth, high moisture,
    and temperatures unfavorable for turfgrass growth. Fertilizing or adding
    iron only exaggerates the condition as the healthy turf turns greener, in
    stark contrast to the sickly colored turf that is not growing. Fortunately,
    with proper mowing and maintenance, the turfgrass should eventually recover.
    A close examination of the yellowing turfgrass should quickly distinguish
    this condition from pale-looking weedy grass species.
