Including your location/garden zone would be a big help. Depends on the weather - the air temps - and the nutrients available. If you feed them and if the air temps allow they will kick back into production assuming they are healthy.

Have you fertilized? How long have they been in the growing? How long were they producing?

Good question. I've just harvested a pile of butternut, and wondered if that was it for the patch. The greenery is pretty healthy, and there are occasional (male) flowers still. I have to assume that a huge amount of energy has been going into the fruit, and I'd like to believe the plants would kick back into productivity now that the fruit are harvested. The plants have been in the ground since March. I've done an occasional top-dressing with compost, but otherwise have pretty much left them alone.
