Light Requirements
Euphorbia mammillosa Lem. prefers to grow in bright sunlight and is highly tolerant to direct sun exposure. In fact, this plant can thrive in full sun without any issue. However, it is essential to protect the plant from frost and cold weather, as it cannot tolerate temperature below 32°F (0°C).
Temperature
Euphorbia mammillosa Lem. prefers warm temperatures and can tolerate a wide range of them. However, the ideal temperature range for this plant is between 60°F (15°C) to 90°F (32°C). The plant should be protected from extreme temperature stresses such as frost, and sudden temperature changes should be avoided.
Soil Requirements
Euphorbia mammillosa Lem. prefers well-draining soils that are not too fertile. A soil mixture of sandy loam or rocky soil with a neutral to slightly alkaline pH is ideal for growing this plant. The addition of perlite or sand can improve soil drainage, which is essential for this plant. Furthermore, this plant is drought-tolerant but will benefit from occasional watering when the top of the soil has become dry to the touch.
Overall, Euphorbia mammillosa Lem. is a resilient plant that can adapt to different conditions but thrives in a warm, dry environment with well-draining soil and bright sunlight. However, it is important to protect the plant from the extreme climate to ensure its healthy growth and survival.
Cultivation
Euphorbia mammillosa Lem. is native to Madagascar and prefers a warm climate with plenty of sunlight. The plant can be grown in containers or directly in the ground. It is essential to choose well-draining soil that is rich in organic matter. The plant is also sensitive to frost and should be protected during the winter months.
Watering Needs
Watering of the plant should be done once a week during the growing season. It is important to allow the soil to dry out slightly between watering to avoid overwatering, which can cause root rot. When watering, it is important to avoid getting water on the leaves or stems, as this can lead to fungal infections.
Fertilization
Euphorbia mammillosa Lem. need to be fertilized to achieve optimum growth. The plant requires a balanced liquid fertilizer that is rich in nutrients and trace minerals. Fertilization should be done once a month during the growing season. When fertilizing, it is vital to follow the instructions on the label carefully, as excess fertilizer can lead to the death of the plant.

After pruning, the plant should be kept in a shaded area for a few days to allow it to recover.
Propagation of Euphorbia mammillosa Lem.
Euphorbia mammillosa Lem. can be propagated through various methods, including stem cuttings, leaf cuttings, and seeds.
Propagation through stem cuttings
The most common method of propagating Euphorbia mammillosa Lem. is through stem cuttings. The stem cuttings should be taken from healthy plants during the growing season. The stems should be cut cleanly using a sharp knife or scissors. The cuttings should be allowed to dry for a few days before being planted into a well-draining soil mixture. The soil should be kept moist, but not waterlogged, and the cuttings should be kept out of direct sunlight until new growth appears.
Propagation through leaf cuttings
Euphorbia mammillosa Lem. can also be propagated through leaf cuttings. The leaves should be removed from a healthy plant and left to dry for a few days. Once they are dry, the leaves should be planted into a well-draining soil mixture. The soil should be kept moist, but not waterlogged, and the cuttings should be kept out of direct sunlight until new growth appears.
Propagation through seeds
Propagation through seeds is another option for Euphorbia mammillosa Lem. Seeds should be sowed in a well-draining soil mixture and kept moist until they germinate. The seeds should be sowed in the spring, as this is when the plant is actively growing. It is important to keep the soil moist and out of direct sunlight until the seeds germinate and new growth appears.
