Candelabra aloe (Aloe arborescens)

Also known as: Octopus plant, Tree aloe

Aloe arborescens, commonly known as Candelabra Aloe, is a flowering succulent indigenous to Southern Africa. It is frequently used as a natural barrier around livestock enclosures due to its dense, spiky foliage, which acts as a deterrent. This species is closely related to Aloe vera and is known for attracting birds, bees, and butterflies. The name "arborescens" translates to "tree-like," reflecting its growth habit.

How to Water Candelabra aloe?

Aloe arborescens, like most succulents, requires careful water management. The soil should be soaked thoroughly until water drains from the bottom of the pot, then allow it to dry completely before the next watering. This mimics rainfall in its natural habitat and prevents root rot.

What Is the Ideal Temperature Range for Candelabra aloe?

Ideal Temperature: 60 ~ 75℉

Aloe arborescens thrives best in a warm environment with temperatures ranging from 60°F to 75°F. This range provides a balance of warmth that allows the plant to photosynthesize efficiently without the risk of dehydration or heat stress. Maintaining temperatures within this range optimizes growth and contributes to the plant’s overall health.

What Soil is Best for Candelabra aloe?

Soil type: Sandy soil, Sandy loam, Calcareous soil

Soil PH: 6.5 ~ 7.5

Aloe arborescens thrives in soils that provide excellent drainage properties. Proper drainage prevents root rot, allowing the plant to take up essential nutrients efficiently. This plant performs well in relatively nutrient-poor soils, reflecting its adaptation to rugged environments. Such conditions prevent over-fertilization, promoting sturdy growth. Slightly alkaline soil, with a pH up to 7.5, is ideal for Aloe arborescens, contributing to optimal growth conditions and ensuring nutrient availability over time.

How to Fertilize Candelabra aloe?

Fertilizer type: Balanced

For Aloe arborescens, balanced fertilizers are recommended. Use a diluted liquid fertilizer at half strength for the first application. Around 5 to 10 ml per liter of water is optimal. For slow-release fertilizers, use approximately 2 grams per pot to provide consistent nutrition over several months.

How to Prune Candelabra aloe?

Pruning Time: Spring, Summer, Autumn, Winter

Begin by inspecting the plant to identify wilted, damaged, or dead leaves. Carefully cut these leaves at their base, taking care not to damage healthy tissue. If the plant is growing too large, trim back excess growth to reshape it. Avoid cutting more than one-third of the plant at once to ensure it remains healthy and vibrant. Ensure that cuts are clean and precise for faster healing.

How to Propagate Candelabra aloe plant?

Propagate Time: Spring, Early summer

Choose a robust and disease-free parent plant, as this increases the chances of successful propagation. Evaluate the plant for any visible signs of stress or weakness.

Use a sharp, sterilized knife to make precise cuts. The ideal cutting should be 10-15 cm long and have at least two leaves for optimal results.

Allow the cuttings to dry and callus over a few days before planting. Use a well-draining soil mix to prevent waterlogging and root rot.

How to Repot Candelabra aloe plant?

Repotting frequency: Every 2-3 years

Aloe arborescens needs repotting when its roots become crowded or start growing out of the pot's drainage holes. Additionally, if the soil becomes compacted or doesn't hold water well, it's a clear signal that repotting is needed. Observing these signs helps ensure the plant thrives.

Select a pot that is slightly larger than the current one, with drainage holes to prevent waterlogging. Terracotta pots are excellent as they allow excess moisture to evaporate, reducing the risk of root rot, which is crucial for succulent health.

Opt for a well-draining cactus mix that mimics the plant's natural habitat. This type of soil prevents root rot by allowing proper water drainage, keeping the roots healthy and aerated, ensuring the plant's robust growth.
