Delay your pumpkins from going mouldy
Once your pumpkin has been carved and drilled, you can delay the onset on mould and rot with a nifty trick. Fill a bucket or other container large enough to hold your pumpkin with around 11 litres of water, then stir in three teaspoons of bleach. Immerse your pumpkin for two minutes, making sure its underwater for the duration, then remove and leave to dry. In an hour or two it should be ready for display. A thorough spraying of WD-40, inside and out, is also said to work.
