A healthy pumpkin will last longer - look for one that is heavy for its size, and has a 'bright' color to it.
- Start by choosing a pumpkin that is free from cuts, bruises, or soft spots, as these can encourage rot.
- Wipe the pumpkin down with a solution of one part bleach to ten parts water. This will kill any bacteria or mold spores on the surface that could cause it to rot. Allow it to air dry thoroughly.
- Keep your pumpkin in a cool, dry place away from direct sunlight and rain. Excess moisture speeds up the decomposition process, so a shady spot on a porch or indoors is ideal.
- Applying a thin layer of petroleum jelly, vegetable oil, or a pumpkin-specific preservative spray over the pumpkin’s surface and any exposed cuts (for carved pumpkins) can help retain moisture and block out bacteria. You can also use a clear acrylic spray to coat the pumpkin.
- For carved pumpkins, spray the interior and carved areas with the bleach solution or rub them with a mixture of lemon juice and vinegar to prevent mold growth. Reapply every few days to maintain protection.
- If the weather is particularly warm, bring the pumpkin indoors or place it in a cool area overnight to help it last longer. Alternatively, you can refrigerate it when not on display.
