The Candelabra Aloe (Aloe arborescens) is a striking succulent known for its multi-branched form and straightforward care. Its architectural presence makes it popular for gardeners in various climates, whether grown outdoors or in containers.
Understanding Your Candelabra Aloe
Native to southeastern Southern Africa, Aloe arborescens thrives in diverse natural habitats. It typically forms a shrub-like structure, eventually developing a woody, tree-like stem with numerous branches, which gives it its common name, Candelabra Aloe.
It features rosettes of sword-shaped, gray-green leaves with small, pale teeth along their edges. These leaves, 15-22 cm (6-7 inches) long, are arranged in a loose rosette at the end of each bare, woody stem. In winter, the plant produces conical flower spikes, typically bright red to orange, that rise above the foliage.
Essential Care Requirements
Light
Candelabra Aloe requires bright, direct sunlight to thrive, ideally at least six hours daily. While it tolerates some partial shade, especially in hotter climates to prevent scorching, full sun promotes optimal growth and flowering. Insufficient light leads to etiolation, causing the plant to stretch and appear leggy with pale leaves. For indoor plants, a south-facing window is often best.
Watering
Correct watering is important for Candelabra Aloe, as overwatering can lead to root rot. The “soak and dry” method is recommended: water thoroughly until it drains from the pot, then allow the soil to dry completely before watering again. During active growth in spring and summer, regular watering is needed, but reduce frequency significantly in winter when the plant is dormant. In cooler seasons, water sparingly, just enough to prevent the soil from becoming bone dry.
Soil
Well-draining soil is essential for Candelabra Aloe, mimicking its natural rocky and sandy habitats. A specialized succulent or cactus potting mix is ideal, designed to prevent water accumulation around the roots. If creating a custom mix, incorporate amendments like perlite, pumice, or coarse sand to ensure excellent drainage and aeration.
Temperature and Airflow
Candelabra Aloe thrives in moderate temperatures, preferring 20°C to 38°C (68°F to 100°F). While it tolerates mild frost, as low as -4°C (25°F) for short periods, prolonged cold below this can cause damage. For container plants in colder climates, bring them indoors when temperatures drop below 10°C (50°F). Good air circulation is also beneficial, helping prevent fungal issues in humid or stagnant conditions.
Fertilization
Candelabra Aloe is not a heavy feeder and requires minimal fertilization. If desired, apply a balanced liquid fertilizer formulated for succulents, diluted to half strength, during the active growing season in spring and summer. Fertilize sparingly, perhaps once a month, to provide necessary nutrients without overfeeding. Avoid fertilizing during the plant’s dormant winter period to prevent nutrient burn.
Repotting Your Candelabra Aloe
Repotting Candelabra Aloe is needed every two to three years, or when the plant becomes root-bound. The best time for repotting is during spring or early summer, allowing the plant time to recover and establish in its new home. Choose a pot only one size larger than the current one, with adequate drainage holes.
When repotting, carefully remove the plant from its old container and gently loosen any circling roots. Place the aloe in the new pot with fresh, well-draining succulent soil, ensuring the base of the plant is at the same level as in the previous pot. After repotting, avoid watering immediately; wait about a week to allow any damaged roots to callous, which helps prevent root rot.
Propagating Candelabra Aloe
Candelabra Aloe can be propagated through offsets, often called pups, which emerge at the base of the parent plant. To propagate, gently remove the offsets when they are about one-third the size of the parent, ensuring they have some roots attached. Allow the removed offsets to dry in a shaded area for a few days until the cut end forms a callus to prevent rot.
Once callused, plant the offsets in a well-draining succulent soil mix. Water sparingly until the new plants are established, allowing the soil to dry completely between waterings. Stem cuttings can also be used, following a similar callusing process before planting. Propagation is best undertaken during spring or summer when the plant is actively growing.
Common Challenges
Despite its hardiness, Candelabra Aloe can encounter a few common problems. Overwatering is a common issue, leading to root rot, characterized by soft, mushy leaves and waterlogged soil. To prevent this, ensure excellent drainage and adhere to a “soak and dry” watering schedule.
Etiolation results from insufficient light, causing the plant to stretch and appear pale or leggy. Moving the plant to a brighter location with more direct sunlight can correct this issue.
Pests like mealybugs and scale insects can sometimes infest Candelabra Aloe. These can be managed by applying insecticidal soap or rubbing alcohol directly to the affected areas with a cotton swab.
