Big Max
Cucurbita maxima — large show pumpkin — 25–45 kg
Big Max is the classic easy-going "big pumpkin" for growers who want impressive size without the full commitment of competitive giant-pumpkin growing. Its reddish-orange, slightly ribbed fruit reaches respectable size on standard vegetable-garden care, making it a popular choice for county fairs, autumn displays, and anyone dipping a toe into large-pumpkin growing for the first time.
🌱 How to Grow Big Max
6–8 hours of direct sun daily. Big Max is more tolerant of partial shade than true giant varieties, but full sun still produces the largest fruit.
Transplant once soil reaches 18°C — Big Max is forgiving of slightly cooler starts compared to Atlantic Giant.
Consistent watering 2–3 times weekly, deep rather than frequent. Even moisture prevents the fruit splitting as it bulks up.
Allow 6–10 m² per plant. A much smaller footprint than true giants, making it realistic for a standard vegetable bed.
Standard balanced vegetable fertiliser every 2–3 weeks. Switch to a potassium-rich feed once fruit sets to support size and skin thickness.
You can let 2–3 fruit develop per plant if you want multiple large pumpkins rather than one giant — Big Max handles multiple fruit better than competition varieties.
🩺 Common Problems
Cause: Humid conditions and dense foliage in late summer
Fix: Improve airflow by thinning leaves, water at the base, and treat early with a sulphur-based spray
Cause: Heat stress or poor pollination during flowering
Fix: Hand-pollinate in the morning during hot spells and provide light afternoon shade in extreme heat
Cause: Common pest on all Cucurbita maxima varieties, feeding on leaves and vines
Fix: Check leaf undersides for egg clusters, remove by hand, and use row covers early in the season
Cause: Fruit resting directly on wet soil
Fix: Place a board or straw under developing fruit to keep it dry and encourage even colouring
