Water: Polaskia Cactus are extremely drought tolerant and are to be watered twice a month during summers and once every month other times of the year. Make sure you do not overwater the plant.
Soil: They prefer alkaline to neutral soil. However, the soil needs to drain well, as residual moisture or puddling can cause the plant to rot.
Lighting: Although this plant is tolerant of high heat, it requires full sun to partial shade. Make sure you protect it from afternoon hot sun.
