How much snow are we talking here? It's been my experience that with a dusting of snow, yes, the greens take longer. I think it has to do with the shorter grass. If the fairways get the same dusting, but are mowed much higher, then the snow tends to get down into the canopy easier, where the heat from the sun's rays will warm the leaf blade and melt the snow. But with the greens being mown much shorter, the same amount of snow will blanket the green, not letting the sun get to the leaf blade, thus slowing the rate of the snow melting. Now if you're talking snow like we get, when it's measured in feet, then all the snow melts at the same rate, but the drifted areas obviously take much longer. In fact, our greens are usually the first areas to clear.
