How to Grow and Care

A location with full sun is best, although Xerosicyos can grow in partial shade. During the winter months, Xerosicyos are kept at a temperature of around 41 to 48 °F (5 to 9 °C) and are watered only enough to keep the leaves from shriveling. USDA hardiness zone 9-11. They are extremely drought tolerant. A deep soaking once a month in the summer will keep the plant looking good.

For pot culture in summer, during the vegetative period, it must be regularly watered, but allowing the soil to completely dry up before watering again (but do not overwater). In winter, it's to be kept dry. Preferable not to water on overcast days, humid days or cold winter days. Xerosicyos adapts to most soil types, but not too heavy in texture; good drainage is desirable. If grown in a pot as an indoor plant use a succulent plants soil. Low food needs. They should be fertilized only once during the active growing period… – See more at: How to Grow and Care for Xerosicyos
