About Myrtillocactus cochal
Myrtillocactus cochal, commonly known as Garambullo, is a branched columnar cactus that can reach considerable heights, eventually forming a tree. Its stems are a distinctive blue-green color, with well-defined ribs and short spines. It is ideal for desert gardens, xeriscaping, or as a striking specimen in large pots on sunny patios.
Native range
Northwestern Mexico
Care tips
It requires full sun for optimal growth, tolerating partial shade in very hot climates. Watering should be moderate in summer, allowing the substrate to dry out completely between waterings, and scarce or none in winter. Use a very well-drained substrate, specific for cacti and succulents. The most common mistake is overwatering, which can lead to root rot.
