Article in English: The pumpkins should be bright orange in colour (depending on the species) with a hard shell. Their stems and often the vine itself should be starting to dry out and wither. They won't keep for more than a few days before spoiling. Use a pair of shears to cut the stem, leaving it a few inches long. Don't break off the stems, since this will cause the pumpkins to rot. Keep them away from humidity, damp, and direct sunlight. They do not need refrigeration. Pumpkins keep for many months after they have been harvested. A mild chlorine rinse before storage can discourage mold and fungi. Use a mix of 1 cup (240 mL) household chlorine bleach and 5 gallons (18.9 L) cold water.
