Hold the horses.
Crab begins to germinate at 50 deg. soil temps, and that has to be a consistent temp not just a daytime hi temp.
Around there, that doesn't happen normally until mid May or so. Last year was anomaly. You have to adjust each year. Find a soil temp website online to use, or go according to your own meter.
The potential for crabgrass to germinate when soil surface temp is 50F degrees is low. The temperature you should be using is when soil surface approaches 60F on average and over.
