An easy-to-make solution can make your carved pumpkins last longer this Halloween against the weather.
After working hard to carve your jack-o'-lantern, it can be a huge bummer to watch it rot away on your porch before Halloween arrives. Watching the weather is the name of the game when it comes to taking care of your carved creation, and depending on where you live, you'll be battling different conditions.
But there are also a few tricks of the jack-o'-lantern trade, including knowing about a "secret" spray solution that can help extend the life of your pumpkin.
Uncarved pumpkins can last two to three months if kept out of the hot sun or freezing nights. Carved pumpkins last a few days, so if you plan to display them, carve within a week of All Hallows' Eve.
If you live in a humid climate, the biggest issues carved pumpkins face are warmth and bugs. Humidity can cause your pumpkin to develop mold and rot quickly. Direct sunlight won't do your pumpkin any favors either because pumpkins shrivel when they dry out, so a shaded porch is an ideal place to display it.
For those who live in a colder climate, freezing nights can be disastrous for your jack-o’-lantern. Pumpkins prefer a cool, dry climate, which means you should bring your pumpkin inside when it’s freezing or raining, or you can keep them on constant display from the inside if you have a street-facing front window.
There are a couple of things you can do before digging into your pumpkin to ensure a long life.
First, pick a hard pumpkin without bruises or soft spots. Those blemishes will speed up the pumpkin's demise.
Before you carve your pumpkin, wipe the outside with a diluted bleach solution. This kills any bacteria that will bring decay. Also, scrape the sides and bottom of your gourd with a spoon to remove all the innards, which are moist and can hasten rot.
There are a few more tricks you can use to treat your carved jack-o'-lantern that can help it survive the Halloween season.
When you're done carving a spine-chilling design, clean the inside and carved parts with a bleach and water solution that will sterilize them and kill any existing bacteria. Just add one teaspoon of bleach per one quart of water, put it in a spray bottle and spray your pumpkin once a day.
If you plan to feed your pumpkin to animals after the season is over, try coating it in vegetable oil instead, which some say is a wildlife-friendly preserving solution. For extra protection against the elements, slather petroleum jelly over the carved edges. This keeps them moist and slows the drying process.
You can also improve your pumpkin’s odds by using the free AccuWeather app to monitor weather conditions. Ideal display conditions are humidity around 50 percent and temperatures in the upper 50s to lower 60s Fahrenheit. Anything below 50 degrees -- or if there’s rain in the forecast -- and you may want to bring your jack-o'-lanterns inside.
