Pumpkins are warm-season cucurbits central to Australian food culture. Three species are commonly grown: C. maxima (Queensland Blue, Jarrahdale), C. moschata (Butternut), and C. pepo (Golden Nugget). They require long warm seasons, ample space, and insect pollination. Excellent storage crops lasting months after harvest.

Watering
Deep watering 2-3 times per week at base of plant. Avoid wetting leaves. Reduce watering as fruit matures to concentrate flavour and improve storage life.
