Euphorbia cooperi, commonly known as the Candelabra Tree, is a striking succulent that embodies both beauty and resilience. Originating from the arid regions of South Africa, this plant has adapted to flourish in environments with minimal water. With its imposing height of up to 7 meters and a diameter reaching about 1.2 meters, the Candelabra Tree makes a bold statement in any landscape. Its unique appearance, resembling the arms of a candelabra, sets it apart from other succulents and becomes a spectacular focal point.
Growing and caring for a Candelabra Tree in your garden requires understanding its natural habitat and replicating those conditions as closely as possible. The Euphorbia cooperi demands ample sunlight, at least 3 to 5 hours daily, and well-drained soil to prevent root rot, a common issue in overly moist environments. When handling this plant, wear gloves and eye protection as it secretes a toxic latex sap which can cause skin and eye irritation.
The Euphorbia cooperi thrives when given the correct care, making it a rewarding addition to your collection of succulents. It’s important to rotate the plant regularly for even exposure to sunlight, which encourages balanced growth. Additionally, being cognizant of the sharp spines and toxic sap adds an element of care when placing the Candelabra Tree in a location frequented by children and pets. With these guidelines, your Euphorbia cooperi will not only grow but will thrive, adding a touch of the exotic to your garden.

Getting Started with Euphorbia Cooperi
Euphorbia cooperi, known as the “Candelabra Tree,” thrives with proper placement and a suitable environment. Your success in growing this plant hinges on the location you choose and the container you provide.
Choosing the Right Location
To ensure the wellbeing of your “Candelabra Tree,” selecting an appropriate location is crucial. This succulent prefers full to partial sunlight, requiring at least 3-5 hours of sunlight daily. Ideal locations may include a sunny spot in your rock garden or any other outdoor area that receives ample sunlight. If you choose to grow it indoors, place it near a window where it can receive adequate light.
- Outdoor: Choose a location with full sun exposure.
- Indoor: A south-facing window is often a prime spot.
Selecting a Suitable Container
When growing Euphorbia cooperi in a container, whether indoors or outdoors, it’s important to use one with well-draining soil to prevent water accumulation and root rot. The pot should also have drainage holes at the bottom:
- Pot Material: Terra cotta or other porous materials help to evaporate excess moisture.
- Soil Mix: A cactus or succulent mix, often amended with perlite or sand, supports proper drainage.
Always handle your “Candelabra Tree” with care during the potting process, wearing gloves to protect against the plant’s toxic sap.
Planting and Soil Requirements
For successful growth of Euphorbia cooperi, known as the “Candelabra Tree,” attention to soil composition and careful planting is crucial. These trees thrive in a specific type of substrate and require correct planting techniques to establish robustly.
Soil Preparation
Your Candelabra Tree demands well-drained soil to prevent root rot, which is essential for its health. Begin by ensuring that your planting medium is loose and gritty. If your garden soil is heavy or clay-like, incorporate materials such as perlite, coarse sand, or gravel to improve drainage. A pH level that is slightly acidic to neutral is optimal, so consider testing your soil’s pH and adjust it if necessary using soil amendments.
- Components for Soil Mixture:
- 1 part garden soil
- 1 part coarse sand or perlite
- 1 part compost (optional, for added nutrients)
When handling soil or the plant itself, wear gloves to protect your skin from the latex sap, which can cause irritation.
Planting Process
When planting your Euphorbia cooperi, select a spot that receives ample sunlight for at least 3 to 5 hours a day. Proceed to plant on a cooler or cloudy day to reduce stress on the cuttings or seedlings.
Prepare Cuttings:
- Use a sterile, sharp knife to remove a stem.
- Allow the stem to callous for several days before planting to reduce sap leakage and infection risk.
Planting Steps:
- Dig a hole as deep as the root ball and twice as wide.
- Place the cutting in the hole and backfill with your prepared soil mix, ensuring the base is level with the surrounding soil surface.
- Water sparingly until established, allowing the soil to dry slightly between waterings.
Monitoring your Euphorbia cooperi closely after planting will help you catch any issues early and ensure a healthy growing process.
Euphorbia Cooperi Care
Proper care for Euphorbia cooperi is essential for its health and growth. Utilize protective gloves when handling and follow these specific guidelines for watering, light exposure, fertilization, and maintenance.
Watering Techniques
Your Euphorbia cooperi requires a “soak and dry” method for watering. Check the soil moisture and water thoroughly only when the soil is completely dry. In the dormant season, reduce watering frequency to avoid overwatering, which can lead to root rot.
Light and Temperature
Place your Candelabra Tree in a location where it receives full to partial sunlight for at least 3-5 hours per day. This succulent thrives in temperatures ranging from 60-85°F (15-29°C) and prefers a climate with low humidity. Protect it from extreme temperature changes and frost.
Fertilizing and Nutrients
Feed your Euphorbia cooperi with a balanced, water-soluble fertilizer during its growing season, typically in spring and summer. Fertilize sparingly, about once a month, to provide essential nutrients without over-fertilizing, which can harm the plant.
Pruning and Maintenance
Regular pruning is not necessary for Euphorbia cooperi, but you may remove any damaged or dead branches as needed. Use sterilized and sharp tools to prevent infection. Throughout the year, ensure the cleanliness around your plant to support its health and new foliage growth.
Propagation and Troubleshooting
Successfully cultivating the Euphorbia cooperi, or “Candelabra Tree”, starts with understanding the correct propagation techniques and handling common issues that may arise.
Propagation Methods
Stem Cuttings: To propagate from stem cuttings, select a healthy stem and make a clean cut using a sterile, sharp knife or scissors. Allow the cutting to callous for a few days, which helps prevent rot when planted. The calloused cutting should be positioned in well-draining soil and kept in a warm, bright environment, ideally under a grow light if indoors.
Seeds: While seeds are an alternative, they may require a more controlled environment. Sowing seeds in well-draining soil and using a seed mat can help maintain the ideal temperature required for germination. Keep in mind that Euphorbia cooperi can take longer to grow from seed.
Common Issues and Solutions
Toxicity: The sap of the Candelabra Tree is toxic and can cause skin irritation. Always wear gloves and goggles when handling the plant, especially during pruning or propagation.
Spine Hazards: The plant’s spines are sharp and can be dangerous, keep it out of reach of children and animals to prevent injury.
Climate: Euphorbia cooperi thrives in a warm climate or as a houseplant in an indoor environment. Ensure it receives plenty of sunlight; an absence can be supplemented with a grow light.
Over/Under-watering: This succulent does not require frequent watering. However, too little water can inhibit growth, while too much can lead to rot. The soil should dry out completely between watering.
By focusing on proper propagation techniques and being mindful of the potential issues, you can grow a robust Euphorbia cooperi, whether in its native region of South Africa or in a suitable environment elsewhere.
