10 tips for growing giant pumpkins
To grow the biggest possible pumpkin, here’s some advice from our horticultural team:
- If you’re starting the seeds in April, sow them in small pots and keep them indoors. Bury the seeds on their edge, about 1cm deep.
- If you prefer to direct sow your seeds outdoors, wait until late May or early June. Pop them into 2.5cm deep holes, and cover with a cloche.
- Why not try both methods, to see which works best?
- Once they germinate, choose the strongest seedlings to grow on.
- Harden off indoor-raised seedlings for 7–10 days before planting outside.
- Plant them in a sunny spot
- Give your pumpkins plenty of space – for ‘Atlantic Giants’, we recommend up to 2m between each plant.
- To get the best results, limit each plant to just one fruit and feed it regularly with a high-potassium fertiliser.
- Water your plants consistently, using a sunk plant pot to avoid overwatering the base.
- To prevent the fruits from rotting, keep them off damp soil using tiles, bricks, or straw.
