Aloe arborescens, commonly known as Krantz aloe, is a succulent with a rich, green appearance. Its thick, fleshy leaves are arranged in rosettes, and they typically bear small, white teeth along the edges, giving them a serrated look. The leaves tend to curve upwards and have a glossy surface that can appear almost luminous in direct sunlight. Throughout the year, but especially during the colder months, the Krantz aloe can produce vibrant, red-orange flowering spikes, which are tubular in shape and grow in clusters. These flowers stand out against the green of the leaves, attracting various pollinators such as bees and birds. The plant has a sturdy, tree-like structure, with leaves that grow densely together, forming a lush display of greenery and color that contributes to its widespread use as an ornamental plant.

  • skullToxicity

    • To humans

      Krantz aloe, commonly known as Aloe arborescens, when ingested, can be toxic to humans. The plant contains anthraquinones, which are compounds that have a laxative effect. If consumed in large quantities, parts of the plant can cause abdominal cramps, diarrhea, dehydration, and can lead to an electrolyte imbalance. It is crucial to avoid consuming any part of the plant, particularly for individuals with kidney or heart conditions, pregnant or breastfeeding women, as the consequences could be more severe for these groups. Topical use of the gel is generally considered safe, but oral ingestion should be avoided unless under the guidance of a healthcare provider.

    • To pets

      Krantz aloe, or Aloe arborescens, is toxic to pets, including dogs and cats. If a pet ingests this plant, the toxic compounds, including saponins and anthraquinones, can cause vomiting, diarrhea, loss of appetite, tremors, and lethargy. Pets may also exhibit a change in urine color. In severe cases, toxicity can lead to depression and may affect the animal's heart rate. It is crucial for pet owners to prevent their pets from ingesting any part of the plant and to seek veterinary attention immediately if they suspect their pet has consumed Krantz aloe.

  • water dropWater

    Krantz Aloe requires infrequent but thorough watering. Allow the soil to dry out completely between waterings, which typically means watering every two to three weeks. When you do water, do so deeply to ensure moisture reaches the root zone; approximately a quart of water for smaller pots or up to 1-2 gallons for larger containers every time you water should suffice, depending on the size of the plant and the environmental conditions. Cut back on watering during the winter months to simulate the plant's natural dormant period.

  • sunLight

    Krantz Aloe thrives best in bright, indirect sunlight but can also tolerate some direct sun. The ideal spot for this plant would be a south or west-facing window where it receives plenty of light. Ensure the plant is protected from the harshest midday sun to prevent leaf scorch, especially in hotter climates.

  • thermometerTemperature

    Krantz Aloe prefers warmer temperatures and does well in a range from 60°F to 80°F. It can survive short periods of cooler temperatures down to about 40°F but should not be exposed to freezing conditions. The ideal conditions for this succulent include average room temperatures and protection from drafts.

  • scissorsPruning

    Pruning Krantz Aloe can be done to remove damaged or diseased leaves and to maintain plant shape. This should be done carefully using clean, sharp tools to prevent infection. The best time to prune is in the spring or early summer, when the plant is entering a period of active growth. Pruning is not required often, but keeping the plant tidy helps promote health and vigor.

    As needed

  • bambooSoil

    Krantz aloe prefers well-draining soil with a sandy or gravelly consistency to prevent root rot. An ideal soil mix consists of two parts sand or perlite and one part potting mix, with a pH between 6.0 and 8.5, slightly on the acidic to neutral side.

  • plantRepotting

    Krantz aloe should be repotted every two to three years, or when it becomes root-bound or the soil is exhausted. Choose a container just slightly larger than the root ball to encourage growth.

  • water dropsHumidity & Misting

    Krantz aloe thrives in dry conditions and does not require high humidity. Average room humidity is sufficient, but the plant prefers an arid environment, similar to its native habitat.

  • circleLife cycle

    Aloe arborescens, commonly known as Krantz aloe, begins its life cycle as a seed, which germinates in well-drained, sandy soil with sufficient warmth and moisture. Upon germination, a small seedling emerges, developing fleshy leaves with a toothed margin, characteristic of the Aloe genus. As the plant matures, it forms a rosette structure and eventually becomes a multi-headed shrub, reaching up to 3 meters in height. The plant undergoes vegetative growth and may produce offsets or "pups" at its base, which can be separated and planted to propagate new individuals. Throughout the winter months, typically between May and July in its native habitat, the Krantz aloe will produce a striking inflorescence consisting of tubular, bright orange to red flowers, attracting pollinators such as birds and insects. After pollination, the flowers develop into seed capsules, and once mature, they release seeds to start the cycle anew.

    • Propogation time

      Spring-Early Summer

    • Propogation: The most popular method of propagation for the Aloe arborescens, commonly known as the Krantz aloe or candelabra aloe, is through offsets, also known as "pups." These pups typically sprout from the base of the parent plant and contain a small portion of root attached. Propagation is ideally done during the warm season when the plant is actively growing. To propagate, carefully remove the pups from the mother plant using a clean, sharp knife or by gently twisting them off. Ensure that each pup has some roots attached. Allow the offsets to dry for one to two days to form a callus over the cut surface, which helps prevent rotting when planted. Plant the pups in well-draining cactus or succulent mix soil, water lightly, and then refrain from watering again until the top inch of soil is dry to touch to encourage root growth.
