I lost all my strawberries two winters ago to frost and as I was tilling last year noticed that some had survived. I babysat these 5 plants and when they sent out runners I rooted them, and today I have about 25 or 30 that are actively blooming and also sending out shoots. I never noticed the old plants sending out shoots in the spring, only in the late summer and fall. Is this normal, should I do anything with then other than train them back into the bed. These new plants are HUGE about 12in tall with leaves as big as my fist.with lots of blossoms.
