Euphorbia Guentheri Cactus is a drought-tolerant succulent from the Euphorbia genus, native to the arid regions of Madagascar. Like many species in its family, it has adapted to long dry spells. It is an exciting find for collectors and beginners alike.
It gets its common name "sausage spurge" from its distinctly segmented, cylindrical stems that stack and bulge noticeably. The plant grows in an upright habit with green stems and a textured, slightly ridged surface on each segment. Rotate the pot every few weeks to encourage balanced growth across all sides. 
It tolerates the dry heated air that drives many houseplants to struggle indoors and shows sensitivity to air blowing directly from AC units or heaters. Position it away from vents. You can leave it up to ten days without water. 
Move it outside in summer to a bright, sheltered spot, but protect it from heavy rain and bring it back inside before temperatures drop in autumn. Keep it on a high shelf well out of reach of pets and small children, as the milky sap can cause skin and paw irritation.

Euphorbia Guentheri Cactus grows well in bright indirect light, partial sun, or full sun, ideally near an east or west-facing window. 
Water it every two to three weeks during the growing season, cutting back to once a month or less in winter. Always allow the soil to dry completely between waterings. 
Euphorbia Guentheri does best in a well-draining cactus and succulent mix, ideally blended with additional perlite or coarse sand. 
It prefers temperatures between 60–90°F and should be brought indoors before nights drop below 50°F. Euphorbia Guentheri is a slow to moderate grower that benefits from diluted balanced fertilizer applied once in spring and once in summer.
It is hardy in USDA zones 9 through 11, where winter temperatures stay above 20–25°F, though it performs best above 50°F. It grows outdoors year-round in California, Arizona, Texas, Florida, Hawaii, Nevada, Louisiana, Georgia, South Carolina, Alabama, Mississippi, and coastal Oregon. With seasonal protection, it can succeed in parts of North Carolina, Virginia, and New Mexico.

A: Water every two to three weeks during the growing season. In winter, reduce watering to once a month or less as growth slows and water needs drop significantly.
