Q. How should I water sansaveria?
Too much water is the most frequent cause of failure in caring for sansevieria. Water moderately, making the potting mixture moist and checking back after 15 minutes to remove any water sitting in the plant's run-off dish.
When the plant is in active growth, allow the soil to just dry between waterings. While the plant is tolerant of extended dryness, succulents do have shallow roots and they will rot easily if over-watered, causing the plant to fall over. In the low-light conditions of winter (October through February), water only as often as is necessary to prevent the leaves from puckering, no more than every two weeks.
For complete care instructions for sansevieria refer to the NYBG guide Snake Plant (Sansevieria).
