When to cover strawberries for winter?
I started a new strawberry bed this year with mostly the Cavendish variety I think. Some were new plants, some were transplanted from a failed container planting of them. I got some straw to cover them with for the winter, but am not sure at what point to apply it. We have had several frosts without snow but the leaves are for the most part still bright green and going strong. From what I read you are supposed to cover them before it gets down to 20F which is supposed to happen later this week with our first snow. Is it okay to cover them in preparation for the big chill even if they are still full of green leaves, or will that cause them to rot. I am in zone 5, near Chicago and the temperature swings can be pretty significant in winter. One day you need a parka and long underwear, then a few days later you can go without even a jacket.
