Warm soils jumpstart spring

What a difference a week makes. Consistent warm temperatures across the region have delivered spring to our doorstep a little early this year. Soil temps in East Lansing hit 51, 55, and 52 over the last three days (compared to 48, 43, and 46 for the same days in 2009). MSU Turf Team recommends using consistent soil temps in the low 50's as the trigger for preemergence crabgrass applications. What does this mean? Well, if temperatures continue to climb we could be looking at crabgrass germination by the middle to end of May. That's about two to three weeks earlier than most years. Perhaps a quick trip to the home center is in order before watching basketball this weekend.
