Here Are some tips on how to care for your pumpkin after its picked.
After harvesting pumpkins, the most important factor in preserving pumpkin
quality is storage temperature. The ideal storage temperature is between 50° F
to 60° F. This temperature range is usually not feasible for most growers with a
six to eight week marketing season. Generally, healthy, disease free, fully
mature, dry fruit can be preserved quite well with fluctuating temperatures
between 35° F and 70° F, which can be achieved in a well ventilated shed that
limits direct sun exposure and provides frost protection.
Keep them cool
Keep them in the shade
Wash them with diluted bleach water
Be Gentle with them
You can even spray them with clear polyurethane
Store the fruits in a cool dry place. Put the fruits on a single layer on
wooden pallets with enough space in between the fruits (the fruits should not
touch each other) and do not place them on a concrete floor. Improve the air
circulation within the storage area by letting in cool air at night and use a
fan to circulate air during daytime. Do not let in warm air from outside into
the storage during the daytime. The optimal storage condition is 50-55°F
temperature and relative humidity of 50-70 percent. The relative humidity is
very important within the 50-70 percent range because high humidity leads to
settling of moisture on fruit surfaces, which increases decay of the fruit and
low relative humidity may cause dehydration of the fruit. Under these conditions you can keep the fruits for about 2-3 months.
Store the fruits away from apples since apples produce ethylene gas as they
ripen which speeds up the ripening process in pumpkins, hence decreased shelf life. Check the fruits regularly and remove the ones that are rotten because if not removed, they will spread the pathogens in the storage area.
