Is there good drainage in your pot? These have a weird water scheduling. In the summer, they usually go dormant so they need little to no water! Starting around August or September they begin to grow again/flower so in the fall you can give them a good watering. But, when winter starts, you should keep the soil absolutely dry even if the leaves start to shrivel, because a new plant body will be growing from the center and taking in water from the older leaves.
I hope this helps!
