Q.How to care for June bearing strawberries?
My June bearing strawberries grow in a raised bed in Tennessee and have just finished fruiting/harvesting. I have seen some advice stating to trim back the leaves to just above the crown and fertilize- but no mention of winter mulching. Other advice says to only remove weeds and dead leaves, fertilize and then mulch for winter.
