grape hyacinth help

hi guys, i have grape hyacinth in my garden but due to the warm autumn and early winter we had, the bulbs sprung very early and they have pretty much been growing since, the flowers have just started to come through which are good an healthy but the whole area looks untidy because the green leaves or foliage came so early they are long, floppy and stringy. can i chop these down a little shorter to tidy things up, essentially give them a haircut so to speak or will this kill them? i've posted a pic below
thanks guys your always a help.
