This game annoys me when I click to shoot and my character wastes a turn to run over to the zombies I wish to stay a respectful distance from... because they smell
Well I grew some more and made a point to harvest them straight away and have them as soon as the ripened... my guess is despite having a wither time of 48 hrs listed, its actually less. I dunno what else could've happened to the first one I grew, it went to Narnia
