freezing corn

I will be freezing my corn this year and was wondering how you all do it. I usually clean and boil for 2 mins. then let cool and stick in bags and freeze or I cut kernels off and bag up and freeze, I was reading an old cook book today and saw where they freeze corn husk and all and said it will last 12 months. Has anyone tried this and does it work. I thought you had to heat to stop the sugar from dissipating?

Thanks,
Susie
