I am taking care of my grandparents old place and the well is only used to water plants outside (i.e. it does not feed into the house). The well will not be used in the winter and I am concerned about it freezing. I do not like the idea of leaving a heater running unattended.
What should be done to shut off a well pump for the winter? Can I simply shut off the power?

Thank you for any assistance.
