Espostoa Lanata - Old man Cactus Hard to Kill Temperature: Best not to letA fuzzy and sought after cacti cultivator. Plant Care Light: Cacti need bright light to survive. My rule of thumb is always to let them have a view of the sky. The best bet is a sunny windowsill. Watering: These plants are drought tolerant. Only water when the soil completely dries out, as overwatering can quickly kill these plants. Cut way back on watering in winter, if at all November March. Temperature: Hardy to 7c IF kept dry during cold spells.
