Cold Hardiness of Worms

21 Feb

WIth temperatures dipping into the mid-20’s and a wind chill well below, I transported several pounds of red worms and european nightcrawlers in the back of a pick up from San Antonio through Houston to southeast Texas.  I knew it was going to get cold, but the forecast for San Antonio was way off.  When planning our trip, the most recent weather reports called for morning temperatures in the mid-50’s.  Thank God for the cold hardiness of these worms.  We finally reached our destination and the 6 hours the worms spent in small bins exposed to these temperatures I feared I would have lost many of the worms.  Temps. in bins dipped well below freezing.

Fortunately, both species (europeans and red wigglers) recovered just fine.  Even the smaller juvenile worms were actively working the next day, as I checked the bins and got them to 50F.

God bless these little guys who prove over and over their resilience in some less than ideal conditions.  I don’t recommend testing the limits, as I typically keep them fairly protected (indoors when possible, the garage, and worm beds several inches underground).
