The “troll plant” is a popular succulent known for its unique appearance and unusual foliage. Its easy care requirements make it an appealing addition to many indoor plant collections.
Identifying the Troll Plant
Troll plants are characterized by their unique tubular, finger-like leaves, which often develop a reddish tint on their tips with sufficient sunlight. These leaves differ from the typical flat, oval leaves of other jade plants. The common name “troll plant” refers to two distinct Crassula ovata cultivars: ‘Gollum’ and ‘Hobbit’.
Troll Plant Care
Light
Troll plants thrive in bright, indirect light indoors, which helps maintain their vibrant appearance and compact growth. A south or west-facing window is often ideal, with filtered light. Some direct morning sun can encourage reddish leaf tips. However, protect them from intense afternoon sun, which can scorch foliage.
Watering
Troll plants prefer a “soak and dry” watering method. Thoroughly water the plant until water drains from the bottom, then allow the soil to dry out completely before the next watering. Watering frequency varies by season, with more needed during warmer months and less in winter. Overwatering can lead to root rot.
Soil
Troll plants require a well-draining, gritty soil mix to prevent waterlogging and promote healthy root development. A specialized succulent or cactus potting mix is suitable. You can also amend standard potting soil with perlite, coarse sand, or pumice to improve drainage.
Temperature and Humidity
Troll plants tolerate average household temperatures, thriving between 65°F and 75°F (18°C-24°C). They are not tolerant of cold temperatures and must be protected from frost. While they appreciate moderate humidity, typical indoor levels are sufficient. Avoid overly humid environments, which can promote fungal issues.
Fertilizing
Fertilizing a troll plant should be done sparingly to support growth. During the active growing season (spring and summer), apply a balanced liquid fertilizer. Dilute the fertilizer to half or quarter strength to avoid over-fertilization. Avoid fertilizing during the dormant winter months.
Propagating Troll Plants
Propagating troll plants is a straightforward process, commonly achieved through stem or leaf cuttings. For stem cuttings, select a healthy stem section that is at least 3-4 inches long and remove the lower leaves. Allow the cut end to dry and form a callus for several days to a week before planting. This callusing process helps prevent rot once the cutting is placed in soil. Once the cutting has callused, plant it in a well-draining succulent potting mix.
For leaf cuttings, gently twist 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 or slightly pressed into the soil. Roots typically begin to form within a few weeks, followed by new plantlets emerging from the base of the leaf or stem.
Common Troll Plant Problems and Solutions
Shriveling leaves indicate underwatering and can be resolved by increasing watering frequency, ensuring the soil is thoroughly soaked each time. Conversely, mushy or yellowing leaves signal overwatering and potential root rot. In such cases, reduce watering frequency and ensure the soil dries out completely between waterings. Leggy growth, characterized by stretched stems and sparse leaves, is a sign of insufficient light. Moving the plant to a brighter location with more indirect light can help correct this.
Troll plants are susceptible to common houseplant pests like mealybugs, which appear as small, white, cottony masses on stems and leaves. These can be treated by dabbing them directly with a cotton swab dipped in rubbing alcohol or using an insecticidal soap specifically formulated for plants.
Toxicity of Troll Plants
Troll plants, like other Crassula ovata varieties, are toxic if ingested. They are toxic to humans and pets, including cats and dogs. Ingestion can lead to symptoms such as vomiting, lethargy, and depression in animals. Place troll plants in locations where children and pets cannot easily access them.
