It's the crisp air and chilly nights that signal it's time again to split and relocate your perennials, apply your lawn treatments, and don't forget to trim any low hanging branches extending over the streets. And also, something easy to overlook is any shrubs or tree limbs that have grown into the alleyways. I know I'd feel really bad if my shrubs were so overgrown that a rescue was impeded.
You should also be thinking about an alternate location for parking your vehicles off of the streets for when the National Weather Station predicts major snowfalls. The snow plow/sander can't open a route if vehicles are parked everywhere on the streets. But, there is always the possibility that we won't have snow this year. (Ya Right)
Have a good Autumn!
