Light
Euphorbia evansii Pax plants require bright and direct light to grow well. This means the plant must receive at least six hours of sunlight per day. The plant should be grown in a location where it can get plenty of direct sunlight without being exposed to harsh direct light. When grown indoors, this plant should be placed near a south-facing window to ensure it receives sufficient light.
Temperature
Euphorbia evansii Pax thrives in warm temperatures which range between 75°F and 85°F. Temperatures below 60°F can make the plant dormant and halt its growth. This plant cannot handle frost, so ensure it is grown in an area with a temperature well above this temperature.
Soil
The soil for Euphorbia evansii Pax should be well-draining and porous to help prevent water accumulation, which can cause root rot. The ideal soil mixture should consist of equal parts of sand, perlite, and peat moss. The pH of the soil should be between 6 and 7.5, which is slightly acidic to neutral in nature, for optimal growth.
Watering
Euphorbia evansii Pax should be watered deeply, at least once a week, during the growing season when the soil is completely dry. During winter, reduce water as the plant goes dormant. Too much water can lead to root rot, so ensure proper drainage is in place.
Fertilizer
Fertilizers should be administered during the growing season, ideally biweekly, at half strength to avoid chemical burn. Use a balanced fertilizer like a 10-10-10 or 15-15-15, which means it should contain equal parts nitrogen, phosphorus, and potassium.
Cultivation methods
Euphorbia evansii Pax is a native plant of Tanzania and can be grown in any tropical or subtropical region. It requires well-drained, sandy, or rocky soil with good ventilation to thrive. The plant grows best in full direct sunlight, but can also tolerate partial shade. Euphorbia evansii Pax is a drought-resistant plant that can survive even in arid conditions.
Watering needs
Watering is essential for Euphorbia evansii Pax, particularly during the growing season. It is best to water the plant once a week, but the watering frequency will depend on the temperature and humidity of the area you live in. During the rainy season, you can cut down on watering as the plant will receive enough water. Overwatering can cause root rot and damage the plant, so be cautious not to water excessively.
Fertilization
Euphorbia evansii Pax should be fed with a slow-release fertilizer during the growing season. Slow-release fertilizer gradually releases nutrients over a more extended period and lowers the chances of over-fertilizing the plant. Fertilizer should be applied once every two to three months for best results.
Pruning
