Crocodile Aloe (Aloe squarrosa) is a distinctive succulent prized for its unique aesthetic and compact size. Its rough, textured leaves are typically blue-green to gray-green, adorned with white, elongated spots. Triangular and recurved (curving backward), its leaves have heavily serrated, spiky edges that contribute to its “crocodile” appearance. Native to the arid limestone cliff-faces and rocky areas of Socotra Island in Yemen, Aloe squarrosa has adapted to arid conditions. Its striking foliage and manageable growth habit make it a popular ornamental houseplant.
Understanding Crocodile Aloe Care
Light Requirements
Crocodile Aloe thrives in bright, indirect sunlight, mimicking its natural habitat. A south or west-facing window indoors provides ideal illumination without intense, scorching rays. Excess direct sun can cause leaf burn, turning leaves red, yellow, or black. Insufficient light leads to etiolation, where the plant stretches and appears leggy, losing its compact rosette form.
Watering Practices
Proper watering is crucial for Aloe squarrosa, which is highly susceptible to root rot from overwatering. Use a “soak and dry” method, allowing the soil to dry out almost completely between waterings. Check soil moisture by inserting a finger or moisture meter a few inches into the soil. Water thoroughly until it drains from the pot’s bottom, then discard excess water. During the spring and summer growing season, water every two to three weeks; in fall and winter, reduce frequency to once a month or less as the plant enters dormancy.
Soil and Potting
A well-draining soil mix is essential for Crocodile Aloe to prevent waterlogging and root rot. A specialized succulent or cactus mix is suitable, or blend regular potting soil with amendments like perlite, coarse sand, or pumice in a 1:1 ratio. These additions improve aeration and drainage, crucial for root health. Always use pots with drainage holes. When repotting, select a container only slightly larger than the current one, as Aloe squarrosa has a shallow root system.
Temperature and Humidity
Aloe squarrosa thrives in moderate temperatures, ideally 60-80°F (15.5-27°C). It is frost-tender; temperatures below 40°F (4.4°C) can cause significant damage or kill the plant. If grown outdoors in cooler zones, bring it indoors before temperatures drop. This aloe prefers a drier environment and does not require high humidity, aligning with its desert origins.
Feeding Your Plant
Crocodile Aloe is not a heavy feeder and thrives with minimal supplemental nutrients. Fertilize sparingly during its active growing season (spring and summer) using a balanced, diluted liquid fertilizer formulated for succulents or cacti. Dilute the fertilizer to half or quarter strength to prevent root burn. Avoid fertilizing in fall and winter when growth slows, as this can lead to a harmful salt buildup. Repotting every two years provides fresh soil and nutrients, often reducing the need for frequent fertilization.
Propagating Crocodile Aloe
Propagate Aloe squarrosa most effectively through offsets, commonly known as “pups,” which emerge from the base of the mature plant. This method is generally more successful than seed propagation for home growers. Carefully separate a pup from the mother plant, ensuring it has at least a few leaves and ideally some roots. If using a knife, clean it thoroughly and make a precise cut, avoiding damage to the parent plant or pup’s roots.
After separation, allow the offset to “callus” by drying it for a few days in a warm, dry place away from direct sunlight. This forms a protective layer over the cut surface, preventing rot when planted. Once callused, plant the pup in a small pot filled with a well-draining succulent or cactus mix. Initially, water sparingly until roots establish, which typically occurs within a few weeks. Propagation is best during spring or summer when the plant is actively growing, promoting quicker establishment and healthier development.
Common Issues and Solutions
Improper watering is a frequent problem for Aloe squarrosa; overwatering often manifests as soft, mushy, or yellowing leaves, leading to root rot, a primary cause of plant demise. If these signs appear, immediately reduce watering frequency and ensure the soil dries completely between waterings. If root rot is severe, repot into fresh, dry, well-draining soil after trimming affected roots. Conversely, underwatering causes leaves to shrivel, wrinkle, or appear dull and limp. To correct this, provide a thorough watering, allowing the plant to soak up moisture before draining excess.
Light issues also affect Crocodile Aloe. Too much direct sun scorches leaves, causing brown or black spots, while insufficient light causes the plant to stretch and become leggy (etiolation). Adjusting placement to bright, indirect light remedies these concerns. Common pests, such as mealybugs and scale insects, may infest the plant. Treat these by wiping them off with a cotton swab dipped in rubbing alcohol, or by using insecticidal soap or neem oil. Regular inspection helps catch infestations early, making treatment more effective.
