Light: It thrives in bright, indirect sunlight, or a few hours of direct, morning sun. An East facing window is ideal. Too much afternoon sun can burn the leaves.
Soil: Ceropegia does best in a fast draining soil, such as a mixture of peat moss, perlite and vermiculite. You can even add sand to help drain. The soil should be moderately moist, but drain well so that it never becomes dense or soggy.
