Crassula ovata ‘Gandalf’ is a succulent known by common names like “Gollum Jade” or “Ogre Ears,” which allude to its unusual leaf shape. It is a popular choice for ornamental displays due to its straightforward care requirements, making it suitable for those new to succulent cultivation.
Understanding Crassula Gandalf
Crassula ovata ‘Gandalf’ is a compact hybrid jade plant with bright green, tubular succulent leaves. These leaves have spoon-shaped cups at their tips, which can develop scarlet red margins when exposed to ample sunlight. Its unique appearance, with leaves resembling fingers or ears, is a key characteristic. This cultivar was developed by cross-breeding Crassula portulacea ibrida (Crassula ovata ‘Gollum’) with Crassula ‘Baby Jade’ (Crassula ovata ‘Minor’). Over time, it forms thick, woody stems, developing a miniature tree-like or bonsai appearance.
Crassula Gandalf Care Guide
Light Needs
Crassula ovata ‘Gandalf’ thrives in bright light, benefiting from some direct sunlight. A south or west-facing window is ideal for indoor cultivation. Protect it from intense, hot afternoon sun, which can scorch its leaves. Adequate light enhances the red coloration on the leaf tips. Insufficient light can cause stems to stretch and leaves to appear less compact.
Watering
Proper watering is important for the health of Crassula ovata ‘Gandalf’. Use the “soak and dry” method: water thoroughly until it drains from the pot, then allow the soil to dry completely before watering again. Overwatering is a common issue leading to root rot, so it is better to underwater. During spring and summer, water every two to three weeks. In fall and winter dormancy, reduce frequency to once a month or less.
Soil Requirements
Crassula ovata ‘Gandalf’ needs well-draining soil to prevent waterlogging and root rot. A specialized succulent or cactus potting mix is suitable. For enhanced drainage, amend standard potting soil with inorganic materials like perlite, pumice, or coarse sand, aiming for 50% to 70% mineral grit. Ensure the pot has drainage holes to facilitate proper water runoff.
Temperature and Humidity
Crassula ovata ‘Gandalf’ prefers moderate temperatures, ideally 65°F to 75°F (18°C-24°C) during the day. While it tolerates cooler nights, protect it from temperatures below 50°F (10°C) and especially from frost, which can cause damage. These succulents are native to arid climates and do not require high humidity, thriving in typical household levels.
Fertilizing
Fertilizing is not necessary for Crassula ovata ‘Gandalf’, but it can encourage vigorous growth, especially in mature plants. If fertilizing, do so sparingly during the active growing season (spring and summer). Use a balanced, water-soluble fertilizer diluted to half or a quarter strength. Avoid fertilizing during fall and winter when growth naturally slows.
Propagating Crassula Gandalf
Propagating Crassula ovata ‘Gandalf’ is straightforward, primarily through stem or leaf cuttings.
For stem cuttings, select a healthy section three to five inches long from the mother plant. After cutting, allow the severed end to dry and form a callus for several days to a week to prevent rot. Once callused, plant the cutting in a well-draining succulent soil mix and place it in a warm location with bright, indirect light.
Leaf propagation involves gently twisting a healthy leaf from the main stem, ensuring the entire base is intact. Allow the leaf to callus for a few days before placing it on top of moist succulent soil. Roots and tiny plantlets typically emerge from the leaf base within a few weeks to a few months. During this initial rooting phase, lightly mist the soil when it dries out. Once roots form, gradually transition to a regular watering schedule.
Common Issues and Troubleshooting
One of the most frequent problems with Crassula ovata ‘Gandalf’ is overwatering, which can lead to root rot. Symptoms include yellowing, mushy, or dropping leaves, and soft stems. To remedy this, allow the soil to dry completely between waterings and ensure the plant is in well-draining soil with drainage holes. Conversely, underwatering causes leaves to shrivel or wrinkle, indicating the plant needs a thorough drink.
Environmental stress also affects the plant; insufficient light can lead to etiolation, where stems stretch and become leggy as the plant reaches for more light. Moving the plant to a brighter location helps, though stretched growth will not revert. Pests like mealybugs or spider mites can infest the plant, appearing as white, cottony masses or fine webbing. Address these by gently wiping leaves with a damp cloth or using a mild insecticidal soap solution.
