The ultimate variety for giant pumpkin contests holding the world record at 1689lb. It requires plenty of space and a warm long summer to reach its full potential, but with care produces exceptional sized pumpkins. Realistically with average care and a good summer, fruit of 200-300 lbs are achievable in the UK. (They are also of excellent texture and flavour). Mature in around 125 days from germination.
A sunny spot protected from strong winds is essential.
The soil must be well drained and rich in humus, the more the better.
Many winter Squash / Pumpkins like to sprawl out and need plenty of space. Vining Squash / Pumpkins require a larger area to run, whilst semi-vining and bush varieties of winter squash / courgette can be well contained.
For an early start (Mid / Late Apr) place a single seed edgeways 1/2inch deep in seed compost in a 3inch pot. The critical part is temperature, these need at least 65F continuous soil temperature (preferably more to maximise germination rates) until germinated, so a propagator, well heated greenhouse or airing cupboard is ideal
Keep the soil moist – water copiously around the plants, not over them.
Keep weed free to allow air circulation.
Once the fruits start to swell feed every 14 days with a tomato type fertilizer, these are greedy plants. Limit larger fruiting varieties to 2-3 fruits (for giant pumpkins 1).
