light
4-5 hours of morning sun and dappled light throughout the hot afternoon is ideal. East and South facing windows are best.
soil

water
Overwatering is the easiest way to kill Lithops. As outer leaves fade, new leaves use water and nutrients. Watering at this time can be deadly. Water when not forming new leaves and only if the soil is completely dry.
fertilizer
It’s optional to fertilize your Lithops, Use a half-strength cactus specific fertilizer right before flowering.
