Monster Pumpkins Competition Guidelines

Send us the estimated weight of your pumpkin and end up on our leader board

If you are one of the lucky 250 schools to receive Monster Pumpkin seeds, follow the instructions below to take part in competition to see who can grow the heaviest pumpkin. Send us your final estimated weight by Friday 27 September and discover how your Monster Pumpkin compares in size to everyone else's.

Sowing your seeds

Aim to sow your pumpkin seeds during the week of Monday 29 April – Sunday 5 May to ensure you’re growing yours at the same time as everybody else.

Tracking the progress of your pumpkins

Read through our resource on estimating the weight of a giant pumpkin. Once your fruit starts to develop (this is likely to be during July) chart your progress using the growth chart included on that page, or use the one on the back of your printed information booklet.

Sending in your measurements

You’ll need to email us with the final estimated weight of your pumpkin and photographic evidence of the circumference, side to side and stem to base measurements by Friday 27 September at the very latest, in order to end up on our final leader board. We’ll remind you nearer the time, as we won't be able to accept any information received after this date.

Announcing the winners

Winners of the competition will be announced on Tuesday 1 October and the leader board will be made available online.

Prizes

Everyone who received Monster Pumpkin seeds from the original 250 will receive a certificate. The top three heaviest pumpkins will win a prize as will the smallest pumpkin on our leader board. The prizes will be awarded as follows:

  • 1st place – £100 worth of National Garden Centre gift vouchers and a school visit from Matthew Oliver
  • 2nd place – £75 worth of National Garden Centre gift vouchers
  • 3rd place – £50 worth of National Garden Centre gift vouchers
  • Smallest pumpkin – £50 worth of National Garden Centre gift vouchers
