How to Grow and Care

Like so many of the small species of Mexican cacti, Ortegocactus is highly prized by collectors. Ortegocactus macdougallii likes light shade to full sun. It is often grafted since it is tricky to grow when on its own roots. Water moderately in summer and very carefully if at all in winter. It show a distinct intolerance to over watering either by rotting off, or by bursting of the epidermis. Grow Ortegocactus in a fast draining mineral mix. To prevent growing a monster totally out of proportion to their attractive and natural form, you should limit the fertilizer.

Many authors recommend grafting, first on Pereskiopsis and soon on Myrtillocactus geometrizans. If it does not reject the stock, it is possible to be cultivated without problems.. – See more at: How to Grow and Care for Ortegocactus
