Pumpkins are a popular fall decoration this time of year, and they are also a beloved feature for Halloween as jack-o-lanterns.

Cynthia Domenghini, a horticulture expert at Kansas State University, advises that to enhance the longevity of pumpkins, they should be harvested or purchased when fully ripened. Pumpkins picked before they reach peak maturity tend to rot more quickly than those harvested at the right time.

To identify a mature pumpkin, look for the following signs: it should have a hard rind that is a consistent color, produce a hollow sound when thumped, and exhibit a waxy coating that helps prevent drying out.

To extend the life of harvested pumpkins, store them in a cool place away from sunlight. However, carved pumpkins have a much shorter lifespan, often rotting within a few days to a week.

To prolong the life of carved pumpkins, thoroughly clean the interior, removing all seeds and string, soak the inside in a 10% bleach-water solution for several hours, avoid using real candles since the heat accelerates rotting, and bring the jack-o-lantern indoors if freezing temperatures are expected due to their high-water content.
