Do you have to remove plastic mulch after the season is over? I have a half acre farm and don't have room/ that much need for a tractor so I hand lay plastic mulch. It is very involved to say the least, and takes me an hour to lay 10' of it. I hear you have to remove it after the season is over. I really don't want to go to this trouble again, every year. Do you REALLY have to take it out? Or is this just a precautionary measure.
