We usually have nights below 40 this time of year, but nights have been strangely warm this year. All the outdoor cacti are in cold frames with the lids kept open. These plants are getting small amounts of rain, but the water will be of little use to them now. These super cold hardy plants are starting to shrink to prepare for their winter rest. Cacti that spend winters under snow get rid of most of their water and become lower to the ground to be ready for a long period of cold days and nights below freezing. Even though the soil around these plants is wet these plants will ignore this water supply until march in the coming spring.
