this is my second year growing strawberries (june bearing) and i'm curious if last season foliage should be trimmed off? i read a few articles saying that in the fall to mow over the patches at 2" height, which i didn't bother doing. i left them unprotected through the winter in the northeast and to my surprise, they still have leaves from last season that are still nice and green, with some new growth starting to emerge. so.. is it better leave the old healthy looking leaves or trim them off? what about fertilizer.. now or when they start flowering? i have fish in 2-3-1 or 5-1-1 which would be best?

btw, these june bearing spread like wild fires.. i did managed to remove some of the off springs in the first few months, but they kept sending out runners, so i gave up. i only planted around 5 of them and now i have around 30 plants scattered around. it's nuts how expensive they sell them for at a nursery, yet they multiply on their own so easily without doing a thing!!
