Giant pumpkin growing competition

Launching our Grow-Your-Own Giant Pumpkin competition starting Friday 5th June 2026! Pick up your free Atlantic Giant pumpkin plant from two lovely Thame businesses on the High Street – Petcare and Bizzie Lizzie Flower Shop!

Grow your pumpkin ready for weighing just before Halloween then carve and cook away!

Open to adults and children – one plant per household.

Please note you must book your pumpkin online using our link on :

They need quite a bit of space and water – see https://www.rhs.org.uk/vegetables/pumpkins/grow-your-own.

This is a Great Big Green Week event supported by Oxfordshire County Council.
