4" Assorted Cactus
Choose a well-draining container, preferably one that is unglazed and will allow evaporation of excess moisture. Use a good cactus mix or make your own blend of 1 part potting soil and 4 parts gritty material. Lighting is of special concern with Huernia cactus care. They grow under plants in their native range and can exhibit stress if grown in searing heat and light. Try an eastern or western window that is bright most of the day but doesn’t experience the hottest rays of the day. A sensible watering schedule is key to caring for Huernia. As with most succulents, the plant is prone to rot if it is too wet, but it does need supplemental water during its growing season. In winter, the plant hardly needs water at all, just once per month on average, as it is mostly dormant and not actively producing growth. In spring through summer, water the plant when the soil is dry to the touch. Make sure any saucer you have is emptied of water to prevent root rot.
