If you live in one of the mid to northern zones, it’s time to bring your worm composter bins inside. The best time to do this is when the temperatures begin to be in the 40″s at night. If left outside, no worries. While your current live worms may die, the eggs laid will hatch when the temperatures are right. But you do need lots of living worms to keep your wormery working thru the winter.
Remember, worm composters are ordorless if fed properly. And keep a top layer of shredded paper on them to keep odors under the paper. If by chance your compost is getting ahead of your worms, just bury the food scraps a bit…especially the onions which i tend to put outside during the winter.
