Q.Ripening Of Butternut Pumpkins
My butternut vines are dying back & most of the pumpkins appear to not be fully ripe with green stripes near the stems. Will these continue to ripen as the vines die right back even though colder weather is upon us or is there something i can do towards this. Also should I keep watering them if rain does not come .

They will, likely, continue to ripen, as it is common for the fruit to remain after the leaves have fallen off.
There isn't much left to do, and the plant will, no longer, be taking up nutrients or water at this point.
Here is an article that will help give you more information on their care:
