I'm not familiar with that particular variety, but I have a strawberry patch in my garden and once all the leaves turn brown and die off, I cut anything above the ground off. So all that remains is just the root. When I did that last fall for the first time, I had the largest strawberry plants I've ever had. they were very big and lush. Not sure if it was because of cutting them all back, or maybe they've just reached a mature age (they are about 3 yrs old now) and are more prolific. But I like to cut back all my perennials in the fall after they've gone dormant because I don't really like the look of dead leaves everywhere that just turn into soggy messes with all the rain we get out in Oregon.
