How long do pumpkins last?

Whole pumpkins last from 2-3 months in cool temperatures. At room temperature, whole pumpkins last about one month. On the other hand, carved pumpkins last 1-2 weeks on a chilly front porch, but only 3-5 days at room temperature.

Whether it’s for Halloween decorations or Fall festivities, picking pumpkins should be done the right way so they last all season!

For the best results of a perfectly preserved pumpkin, read on for how to keep your pumpkins—carved or not—in good shape throughout the Fall months!

How to pick a good pumpkin?

Whether at the pumpkin patch or the grocery store, to get the greatest life span out of your pumpkin, choose healthy pumpkins that have:

  • Green stems
  • Hollow sound
  • Firm skin
  • Vibrant orange color

Don’t pick pumpkins with:

  • Soft spots
  • Broken stem
  • Hard, brown textures

How to preserve a carved pumpkin?

These 6 steps will give your Halloween pumpkin a fresher look that’ll last all Fall season long. Each step has a few different options, so go with your personal preference and have fun!

1. Cut open and scrape out the guts and seeds.

​The first step is the messiest and most meticulous step. Make sure to completely gut your pumpkin—seeds and all—because this is where the rotting starts first. Use something like a pumpkin carving knife and a big metal spoon to really get all the insides out.

Also, don’t let those pumpkin seeds go to waste! Check out these recipes to use your pumpkin seeds:

2. Pat down and spray the inside.

​Pat down the outside and inside of your pumpkin with a paper towel. Then, thoroughly spray the inside AND outside with a water and bleach solution. To create the spray, use one teaspoon of bleach for every 4 cups of water.

If you don’t have bleach, you can use a peppermint soap or oil instead. Peppermint does have antifungal properties, so it will work just like the bleach. 

3. Allow pumpkin to dry.

​Do not pat down your pumpkin once you’ve sprayed it. Let it dry completely, which could take several hours. To speed up this process, feel free to use a fan on a low setting.

4. Carve your pumpkin!

This step is the best step—carving your pumpkin! Use permanent markers to draw out your pumpkin face vision, or even use pumpkin carving stencils to add that picture-perfect touch. 

5. Submerge in a bleach & water bath.

You may have finished carving your pumpkin, but you’re not done preserving it yet. The rotting process will start eventually, but you can still increase the life span of the cut parts.

One optional way to do this is to use a big bowl to fully submerge your pumpkin in a bleach and water solution. For every gallon of water, add ⅓-cup of bleach. Let it submerge for several hours, then dry completely.

6. Coat the carved parts.

While the prior step is optional, if you decide to skip it, you’ll still want to cover this step: coating the carved parts of your pumpkin. Use petroleum jelly, vegetable oil, olive oilor even WD-40 to coat each cut part. Then you’ll be ready to leave your pumpkin on your front porch!

You can also finish the pumpkin off with a coat of hairspray. This will give it a glossy, polished look.

How to preserve uncarved pumpkins?

The best way to preserve an uncarved pumpkin is to clean the outside of it, pat dry, and spray with either a water and vinegar or water and bleach solution.
