Whether you are growing pumpkins for a Halloween Jack-o-lantern or for a tasty pie, nothing can be more disappointing than a frost that kills your pumpkin plant with green pumpkins still on it. But never fear, there are things you can try to get your green pumpkin to turn orange.
- Harvest the green pumpkin – Cut your pumpkin off the vine, making sure to leave at least 4 inches (10 cm.) of the vine on the top. The “handle” will help prevent the pumpkin from rotting at the top.
- Clean your green pumpkin – The biggest threat to a green pumpkin is rot and mold. Gently wash the mud and dirt from the pumpkin. After the pumpkin is clean, dry it and then wipe it down with a diluted bleach solution.
- Find a warm, dry, sunny spot – Pumpkins need sunlight and warmth to ripen and a dry place so they don’t rot or mold. Enclosed porches generally make a good place, but any warm, dry, sunny spot you have in your yard or house will work.
- Place the green side to the sun – The sun will help the green part of the pumpkin turn orange. If you have a pumpkin that is only partially green, face the green side towards the sun. If the whole pumpkin is green, rotate the pumpkin evenly for an even change to orange.
