Euphorbia gamkensis is a beautiful succulent plant with large, pretty much cylindrical shaped underground caudex up to 6 cm in diameter. Above-ground, a few rows of outwardly pointing thick, succulent stems grow on the often flat green top of the caudex. The outer row of stems is the longest, the oldest. New stems emerge in the center as the plant grows in width. Scattered whitish stalks can be seen on the older stems where small greenish-yellow cyathia had bloomed in the past. The stems are covered in rhomboid tubercles, small rounded sections that bulge on the stems and multiply as new ones emerge from the center at the top. The top parts of the stems are the greenest here, being the youngest.

How to grow and maintain Euphorbia gamkensis:
It prefers full to partial sunlight. Provides good sunlight at least 3-5 hours of the day, and turn it regularly so that your plant doesn’t begin to grow lopsided.
It grows well in well-draining, gritty soils or cactus potting mix. They are not particular about soil pH, but they cannot tolerate wet soil.
You can allow the soil to dry out between each watering. Before watering the plant check underneath the pot through the drainage holes to see if the roots are dry. If so then add some water. Do not water too often to prevent overwatering, that can potentially kill it off.
It prefers an optimal temperatures of 60 degrees Fahrenheit – 85 degrees Fahrenheit / 16 degrees Celsius to 29 degrees Celsius.
Fertilize every two weeks with a diluted balanced liquid fertilizer during its growing season in the spring and summer. Avoid fertilizing your plant during the fall and winter months.
Euphorbia can be easily propagated by cuttings. Take cutting in spring, which needs to be dried out for a couple of weeks before potting. Also can be propagated from seed, but they can be difficult to germinate.
Pests and Diseases:
Euphorbia may be susceptible to mealybugs, scale insects, occasionally spider mites.
