Usually mid-August is when I turn my lighting system back on as it is finally getting dark enough, and early enough for the lights to have an impact.
Also, this is a good time to start up the hot tub, although many people like to start it up during the September long weekend.
You can do one last fertilizing on the lawn but not after this date, as you will encourage week grass going into winter if winter comes early.
On that note, winter is supposed to come nine weeks after the last pink flowering fireweed has flowered in your area.
