If your goal is just to have homegrown strawberries all year round, you can always divide a large bed into June-bearing, everbearing, and day-neutral varieties and also use any or all of the methods for protecting your plants outside the usual summer growing season. Just match the type of strawberry to the kind of protection you are giving your plants, and don't forget that strawberries need long, daily periods of sunlight or artificial light to put on fruit.
