How to Grow and Care

They are semi-hardy, make sure that your Myrtillocactus are not exposed to temperatures below 25°F (-4°C), or they may die. Nevertheless, it is good advice never to let the nighttime's temperatures fall below 50°F (10°C). In the summer, place Myrtillocactus in the sunshine (indoors or outdoors). In the winter, find a cooler, light spot. That will allow it to go into next spring well-rested, which will make it more likely to flower. This easy-care plant doesn't want a lot of water. Allow the soil to dry out before you give it another drink. Keep the soil completely dry in winter. Treat it to special cactus food once a month in the spring and summer.

If the plant needs repotting, use a fairly impoverished soil specially designed for cacti. By seed or cutting (allow the cut surface to dry out for 2-3 weeks before placing in an open rooting media). See more at How to Grow and Care for Myrtillocactus.
