Yes, the cold temps would be a factor too, it likes to be in warm conditions like 60F to 80F (15C to 26C). So if you can position it to a warmer area with lots of light. I wonder if you have those root heating mats, that can help too encourage rooting. I usually put aloes and succulents in a gritty cacti mix, so it does not stay soggy for a long time. If it gets too soggy and cold, it will rot the roots.
