According to the Guinness Book of Records, “the heaviest pumpkin weighs 1,054 kg (2,323 lb), was grown by Beni Meier (Switzerland) and authenticated by the Great Pumpkin Commonwealth (GPC) in Ludwigsburg, Germany, on 12 October 2014.”
The New Zealand record (at the time of writing) is a 754.5kg whopper. We have no doubt it won’t be too many years before we see a New Zealand grower as the giant pumpkin world champ.
