Any daylily or tulip enthusiasts may be bemoaning the recent cold snap that left many early-greening plants very sad across much of Iowa. Well, cold weather can be our friend as well. On April 7 and 8, a cold front pushed as far south as the Florida Panhandle, and kudzu growth was slowed or knocked back from this record-breaking frost. The freezing temperatures on the rapidly growing kudzu in this area could reduce the buildup and potential spread of soybean rust for several weeks. This frost came much later than their March 15 "frost-free" date.
