Light
Euphorbia celastroides Boiss. var. saxicola O. Deg. & Sherff prefers full sunlight and requires at least six to eight hours of direct sunlight daily to maintain healthy growth. The plant cannot tolerate shade, so planting it in a shaded area could cause stunted growth, yellowing of leaves and poor performance.
Temperature

Therefore, it is best to plant Euphorbia celastroides Boiss. var. saxicola O. Deg. & Sherff in a location with moderate temperatures throughout the year.
Soil
The plant prefers soil that is well-drained, light and sandy. It can grow in average to mildly acidic soil with a pH range of 6.0 to 7.5. Rock spurge can tolerate infertile soil, and it is best to avoid over-fertilizing, which can cause the plant to produce excessive foliage and weak branching.
Cultivation
Euphorbia celastroides Boiss. var. saxicola O. Deg. & Sherff is a hardy plant that is relatively easy to cultivate. It can be grown in pots or garden beds, and it thrives in well-draining sandy soil.
When planting, make sure to place it in a location that receives plenty of sunlight. This plant can grow in both partial shade and full sun.
Watering Needs
Like most succulents, Euphorbia celastroides Boiss. var. saxicola O. Deg. & Sherff prefers to be watered infrequently, but deeply. Allow the soil to dry out completely between watering. During the hotter months, when the plant is actively growing, it may require more regular watering.
It's important not to overwater this plant, as it is susceptible to root rot if the soil remains too wet for extended periods.
Fertilization
During the growing season, fertilize your Euphorbia celastroides Boiss. var. saxicola O. Deg. & Sherff with a succulent fertilizer every two to three weeks. This will help promote healthy growth and flowering.
However, be careful not to over-fertilize, as this can cause the plant to grow too quickly and become weak and leggy.
