At the foot of the Snowy Mountains in southern New South Wales, a spectacle unfolds as a man rows a giant pumpkin down the Tumut River. The process of cultivating such massive pumpkins requires scientific expertise. Mark Peacock, a horticultural scientist from Tumut, has successfully grown pumpkins large enough for this unique activity.
Mark's journey into giant pumpkin cultivation began during the COVID-19 lockdown in North Carolina, where he grew a 340-kilogram pumpkin. His efforts have since resulted in a 407kg pumpkin, which was recognized at the Sydney Royal Easter Show in 2024, and a 426kg pumpkin that won at the Tumut Show's giant pumpkin category.
Growing these pumpkins involves managing soil quality, frost, pest, and disease issues. Mark emphasizes the importance of the plant's placement and uses sand to reduce friction as the pumpkin grows. UV light management is also critical, with tents used to prevent premature hardening of the pumpkin skin.
Mark's sister, Emma Peacock, notes his dedication to promoting giant pumpkin cultivation in the region. A new category at the local show has spurred interest, leading to the establishment of a grower's group with over 20 members. Mark shares his expertise and seeds, encouraging local participation.
Ethan Buckley, a group member, achieved a 142kg pumpkin on his first attempt. Despite not reaching the size needed to row down the river, Ethan remains determined to surpass Mark's achievements in future endeavors.
