Light: Euphorbia candelabrum Kotschy requires full sunlight exposure for optimal growth. It can tolerate some shade, but it may result in slower growth and smaller overall size. Therefore, it is best to provide it with at least six hours of direct sunlight every day.
Temperature: This plant is native to the African continent, where it thrives in a warm and arid climate. It can withstand extreme heat, up to 104°F (40°C), as long as it receives adequate hydration. However, it cannot tolerate frost or temperatures below 50°F (10°C). Therefore, it is essential to protect it from cold weather during winter months.
Soil: Euphorbia candelabrum Kotschy prefers well-draining, slightly acidic to neutral soil with a pH range of 6.0 to 7.5. It can tolerate various soil types, including sandy, loamy, and rocky soils. However, make sure that the soil is not waterlogged, as it may cause root rot and other diseases. Additionally, it is beneficial to add organic matter to the soil to increase its fertility and moisture retention capacity.
Water: Euphorbia candelabrum Kotschy requires moderate watering during the growing season, from spring to fall. It can withstand short periods of drought, but it may result in stunted growth and wilted leaves. Therefore, it is best to water it when the top inch of soil feels dry to the touch. Additionally, make sure that the water drains quickly from the soil to prevent waterlogging.
Fertilizer: This plant does not require frequent fertilization, but it can benefit from occasional feeding during the growing season. Use a balanced, slow-release fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Apply it at half strength every two to three months, or according to the manufacturer's instructions.
Cultivation of Euphorbia candelabrum Kotschy
Euphorbia candelabrum Kotschy, commonly known as the candelabra tree, can be propagated from seeds or cuttings. The optimal time for sowing seeds is during the rainy season when the soil is moist. The seeds should be planted in well-draining soil and placed in a bright location. Cuttings can be taken from mature plants and planted in a pot with a mixture of sand and soil. It is essential to keep the soil moist until the plant has established roots.
Watering Needs of Euphorbia candelabrum Kotschy
Euphorbia candelabrum Kotschy requires regular watering during the growing season. It is essential to let the soil dry out slightly between waterings to prevent root rot. During the dormant season, the plant requires less water. It is important to avoid getting water on the leaves and stem as this can lead to fungal diseases.
Fertilization of Euphorbia candelabrum Kotschy
Euphorbia candelabrum Kotschy requires fertilization during the growing season. A balanced fertilizer should be used once a month to provide the necessary nutrients for healthy growth. It is important to follow the instructions on the fertilizer package and avoid over-fertilizing as this can damage the plant.
Pruning of Euphorbia candelabrum Kotschy
Euphorbia candelabrum Kotschy requires minimal pruning. Any dead or damaged branches can be removed with sharp, sterilized pruning shears. It is important to wear gloves when handling the plant as the sap can be toxic and cause skin irritation. It is also important to avoid cutting back too much of the plant as this can stunt its growth and affect its overall appearance.
Propagation of Euphorbia candelabrum Kotschy
Euphorbia candelabrum Kotschy, also known as the Candelabra Tree or the Abyssinian Euphorbia, is a succulent tree that is native to East Africa and parts of the Arabian Peninsula. The plant has attractive, cactus-like branches and can reach heights of up to 10 meters.
Propagation by Cuttings
One of the most common methods of propagating Euphorbia candelabrum Kotschy is by using stem cuttings. The best time to take cuttings is during the active growth period of the plant, which is typically in the spring and summer months. To take cuttings:
- Use clean, sharp pruning shears or a knife to cut a stem from the parent plant. Make sure the cutting is at least 10cm long and has several leaves.
- Allow the stem to dry in a warm, dry area for a few days until the cut end has calloused over.
- Fill a pot with well-draining soil and make a hole in the center.
- Dip the cut end of the stem in rooting hormone and then place it in the hole in the soil.
- Water the cutting lightly and then cover the pot with a plastic bag or dome to create a humid environment for the cutting.
- Keep the cutting in a bright area, but out of direct sunlight. Water the cutting lightly every few days to keep the soil slightly moist.
- After a few weeks, roots should begin to form. You can tell that the cutting has rooted by giving it a gentle tug, if it resists being pulled out of the soil, then it has rooted successfully.
Propagation by Seeds
You can also propagate Euphorbia candelabrum Kotschy by collecting and sowing its seeds:
- Harvest the seeds from a mature plant in early autumn and allow them to dry for a few days.
- Fill a shallow tray with well-draining soil and then sprinkle the seeds over the surface. Do not bury the seeds in the soil.
- Water the tray lightly and then cover it with plastic wrap to maintain humidity.
- Place the tray in a bright, warm area. Once the seedlings have emerged, they can be removed from the tray and planted in individual pots.
- Water the seedlings sparingly and keep them in a bright area, but out of direct sunlight, until they are established.
Propagation of Euphorbia candelabrum Kotschy can be a fun and rewarding process. Whether you choose to propagate the plant by cuttings or by seeds, creating new plants is a great way to increase your collection and share the joy of these stunning succulents with others.

Fungal leaf spot: Fungal leaf spot is another common disease that affects Euphorbia candelabrum Kotschy. It is caused by several fungi and can cause yellow or brown spots to appear on the leaves. To prevent fungal leaf spot, avoid getting water on the leaves and provide good air circulation around the plant. If the plant is infected, remove all affected leaves and treat it with a fungicide.
Pests
Spider mites: Spider mites are a common pest that feed on Euphorbia candelabrum Kotschy and can cause the leaves to become discolored and distorted. To prevent spider mites, keep the plant well-hydrated and mist it occasionally to increase humidity. If the plant is infested, treat it with a miticide.
Mealybugs: Mealybugs are another common pest that can infest Euphorbia candelabrum Kotschy and feed on its sap. They can cause the leaves to become sticky and attract ants. To prevent mealybugs, inspect the plant regularly and remove any visible pests. If the plant is infested, treat it with insecticidal soap or neem oil.
