How to grow

Sow indoors from mid-April, one seed on its side per module or small pot. Transplant outside from early June, into a sunny spot where the soil has been enriched with organic matter. Cover with fleece if it’s cold or late frosts are likely. In colder regions it may be necessary to grow under cover. Keep well watered and feed when flowers and fruits are forming. Lay ripening fruits on straw, black polythene or a tile to prevent rotting.

Growing big pumpkins

  • Choose the right pumpkin cultivar. Some of the biggest include ‘Atlantic Giant’, ‘Mammoth’, ‘Paton Twins Giant’ and ‘Hundredweight’
  • Grow pumpkins in the ground in full sun. Prepare the soil beforehand by digging in lots of well-rotted manure. Keep the soil moist but not waterlogged
  • Remove all flowers until the vine reaches around 10m in length
  • Wait for 2-3 pumpkins per plant to grow to tennis ball size, then remove all except the best, healthiest pumpkin
  • Adjust the pumpkin to ensure the stem is perpendicular to the main vine, so it doesn’t snap later on
  • Protect the chosen pumpkin by shading it and sitting on a bed of straw or sand
  • Let sideshoots from the main vine reach 2.5m in length, then pinch out. Also pinch out the main vine just after where the pumpkin is growing from
  • Keep up your care regimen right up until the first frosts
