I agree with Philemon, now is the time to spend as much time outdoors as possible. Since our last equinox we have lost hours of daylight and the temps have dropped about 20 degrees from the highs and the lows of the day. I woke up this morning to about 36 degrees... way to close to freezing for me.
If you are new to the Northern climate and a new home owner as well there are steps you need to take immediate action on. I would suggest starting out by visiting with a local expert (not YouTude) at Home Depot as to what are typical weatherization measures to take before our harsh winter strikes.
Steps I typically take are:
1) Mow your lawn fairly short but don't scalp it. Leaves blow over the lawn with the short grass. They are going to fall... do you want to rake all the leaves in the neighborhood or let them move on down the line?
2) If you have window AC remove and maintain them for the winter. At this point I assure you that you won't need them anymore for about 9 months.
3) Kill weeds and grass that are encroaching upon your sidewalk and driveway. You will be shoveling soon and/or using a snow thrower. A clump of weeds growing threw a crack is going to stop your shovel and it is most likely going to send that shovel into your body... probably where it hurts the most 😉.
Winter doesn't last forever... it just seems like it up North so prepare for it and things will go better for you.
