im sorry i meant the lawn.

I live in Rockland county too. IMHO, the window of opportunity to winterize in this area is past. Temperatures here are mostly in the upper thirties and low forties. Turf Grass has gone dormant already.

Roots do continue to function down into the upper 30's or so. Plus, the soil might be warmer than you would imagine 2" down even if it has been in the 30's overnight. If it were me, I'd fertilize if I could still stick a shovel in the ground. Not much to lose unless your lawn is huge.

I'm just a few miles north of you in lower Orange County. The opportunity to winterize is clearly past. It was late this year, but was at the very end of November.
