How to Propagate Strombocactus?
Primary propagation of strombocactus is through seeds, as cuttings are not viable with this cactus. Key factors for success include high light exposure, warm temperatures, well-draining mineral soil, and low humidity. Germination can be slow and challenging due to the plant's rarity and slow growth rate. Sow seeds in spring or summer: 1) Fill pots with a gritty soil mix; 2) scatter seeds on soil surface; 3) cover lightly with sand; 4) keep moist in a bright, warm place. Due to its specific needs and slow growth, propagation is generally difficult.
