Cactus 4 Stem

It is an erect shrub growing up to 5 metres (16 ft) tall, with succulent branches 3–5 centimetres (1.2–2.0 in) in diameter, ridged, with a triangular or rhombic cross-section; the ridges are spiny, with short spines up to 5 millimetres (0.20 in) long. The leaves are minute, and soon deciduous. All parts of the plant contain poisonous milky latex.

Watering

It cannot tolerate wet soil, but you can allow the soil to dry out after each watering. Water consistently in summer to prevent soils from totally drying out and decrease watering in winter.

Lights 

Full sun to partial shaded.
