Lighting: These cacti need full sun, meaning at least six hours of direct sunlight on most days, to grow and flower their best. A south-facing window is best
Watering: These cacti don’t need much moisture to thrive and too much humidity causes the stems to rot. During the winter months when the plant is dormant, it requires less water. Be sure to let the soil dry out between watering. Water roughly every two weeks from spring to fall and monthly during the winter.
