Most of us in the coastal area of zone 9 California will grow 'everbearing' or day neutral strawberries and enjoy the fruit all summer. For your system I would keep them growing and healthy all year until winter frost when I would cut the foliage back. I like to start the season with new clean foliage. Al

Overwintering? WINTER......SLOWLY I TURN. The sight of the word winter freaks me out. Please don't mention it for at least anoter 2 months. We're trying to enjoy our summer up here in the NE. Only kidding :-);-)

There's plenty of information about "renovating" strawberries, depending on which types, June bearing, or everbearing, that you are growing. I have June bearing, and trim off the tops of the plants after harvest, and continue to water them which establishes the plant for next year. I nurture any runners that I will use to replace spent plants over a few years old.
