The plant does not do well in cold temperatures and may not survive if exposed to frost. It is important to keep the plant away from drafty areas and air-conditioning units.
Soil Requirements
Euphorbia forskalii J.Gay prefers well-draining soils that are fertile and have a slightly acidic to neutral pH level. The soil should be rich in organic matter and have good water retention capacity. The recommended soil mixture for Euphorbia forskalii J.Gay is composed of two parts peat moss, one part perlite, and one part sand. The plant should be watered thoroughly after planting and then watered whenever the top inch of the soil feels dry to the touch. Overwatering can harm the plant, so it is important to let the soil dry out between waterings.

To improve drainage, add some sand to the soil before planting. This plant thrives in areas that receive plenty of sunlight and can tolerate high temperatures.
Watering needs
Euphorbia forskalii J.Gay has low watering needs. Inadequate water will not affect the plant; however, overwatering will cause the roots to rot. Water the plant only when the soil is dry and when necessary. In areas with hot temperatures, the plant might need more water than in areas with cooler temperatures, as the water will evaporate faster.
Fertilization
Euphorbia forskalii J.Gay is not a heavy feeder. Therefore, over-fertilizing can do more harm than good. It is best to use a low-nitrogen fertilizer once a month during the growing season. A low concentration of fertilizer will enable the plant to grow at a healthy rate.
Pruning
Pruning the Euphorbia forskalii J.Gay is not necessary. However, it is best to remove dead or dying branches to encourage the growth of new ones. Use pruning shears to remove dead branches that are close to the stem to avoid injuring the stem. If the plant becomes too large for the space, use pruning shears to trim back the branches to the desired size and shape.

- Leaf spot: This fungal disease causes circular brown spots on leaves, which may eventually turn yellow and fall off. Proper air circulation and avoiding overhead watering can help prevent leaf spot. If the disease is already present, removing and destroying affected leaves can help manage the spread.
- Powdery mildew: This fungal disease causes a white powdery coating on leaves, stems, and flowers. It usually thrives in humid conditions. To manage powdery mildew, it is essential to keep the plant in a well-ventilated area and avoid overhead watering.
Common Pests of Euphorbia forskalii J.Gay
