This time of year is an ideal time to winterize your property.
Take the time to go around the exterior of your home, make sure any openings are closed up* replace caulking* install storm windows*put away outdoor furniture*clear out your gutters and make sure the downspouts are away from the property.
Exterior maintenance can also include yardwork and if you havent already done so, now would be a good time to roughly dig over the soil - the winter will break the clumps down! Clean up deadfall, cut the grass and try and get as many leaves and branches off the grass as possible.
Most of all, think of Fall as just another season and as with every season, there are positives and negatives that go along with it.
Most municipalities have tip sheets available and the garden centre websites are a great resource for yard care.
