Cultivation methods:
Euphorbia enopla Boiss. var. viridis A.C.White, R.A.Dyer & B.Sloane is a tropical succulent plant that requires a warm climate to grow well. It is typically grown in pots or containers due to its slow-growing nature. When planting, it is advisable to add a mixture of organic compost and coarse sand in equal parts. This provides good drainage and helps avoid root rot.

Euphorbia enopla Boiss. var. viridis A.C.White, R.A.Dyer & B.Sloane can be grown indoors provided there is sufficient sunlight and good air circulation.
Watering needs:
The plant is drought-tolerant and can go for long periods without being watered. However, it is best to water the plant when the soil is completely dry to the touch. It is advised to allow the water to drain out of the pot or container entirely to prevent root rot. Overwatering can lead to root rot and other complications.
During the winter months, reduce the amount of water to prevent the soil from becoming waterlogged. It is best to reduce watering by about 50% during this season.
Fertilization:

Pruning:
Pruning should only be done as a last resort. The best time to prune is during the spring season, when the plant starts to grow again. When pruning, wear gloves, as the plant is covered in sharp spines. Cut off any dead or damaged leaves and stems using sterile pruning shears. Avoid cutting the stem too close to the base, as this may damage the plant's growth.
Also, avoid touching the white sap, which is toxic and can cause skin irritation and other allergic reactions. Always wash your hands thoroughly after handling the plant.
