Silver Moon
Cucurbita maxima — white giant — 15–35 kg
Silver Moon is a ghostly pale-white giant pumpkin with a distinctive, slightly flattened shape. It's on the smaller end of the giant spectrum, which makes it easier to size up in shorter seasons — and its striking colour makes it a standout choice for white-pumpkin displays without needing the full commitment of larger giant varieties.
🌱 How to Grow Silver Moon
6–8 hours of direct sun. Keeps the pale skin clean and evenly coloured without any green tinge lingering.
Transplant once soil reaches 16–18°C — one of the more cold-tolerant giants at transplant time.
Even watering 2–3 times weekly. Consistency prevents cracking on the thinner, pale skin as the fruit bulks up.
Allow 8–12 m² per plant. A manageable footprint, smaller than most true giants.
Balanced fertiliser through vegetative growth, shifting to potassium-rich feed once fruit sets for size and firm skin.
Rotate the developing fruit gently every few days to keep its flattened shape symmetrical and prevent one side flattening more than the other.
🩺 Common Problems
Cause: Pale skin shows dirt and moisture contact marks easily
Fix: Rest the fruit on straw or a board to keep it clean and dry
Cause: Uneven ground contact as the naturally flattened fruit develops
Fix: Rotate gently every few days early in development for a more even shape
Cause: Humid, still air around dense foliage
Fix: Thin surrounding leaves for airflow and treat early with a sulphur-based spray
Cause: Cool soil at transplant slowing early root establishment
Fix: Warm the bed with black plastic mulch 1–2 weeks before transplanting
❓ Common Questions
How big does Silver Moon get?
Typically 15–35 kg — on the smaller end of the giant-pumpkin spectrum, but distinctive for its ghostly white colour.
How is it different from Full Moon?
Silver Moon tends toward a flattened, wider shape and a shorter season, while Full Moon is rounder with a longer maturity window.
How long does it take to mature?
100–115 days from seed to harvest, one of the shorter seasons among giant pumpkin varieties.
Is it good for a first giant pumpkin attempt?
Yes — its smaller target weight and shorter season make it far more forgiving than true competition giants.
