The term “green coral plant” is a common name for succulents with coral-like foliage, not a scientific classification. This article focuses on the most common association: Crassula ovata ‘Gollum’ or ‘Hobbit’ Jade, known for its distinctive appearance and popularity. We will explore its specific care and propagation needs.
Identifying Your Green Coral Plant
The plant commonly referred to as “green coral plant” is a cultivar of the jade plant, specifically Crassula ovata ‘Gollum’ or Crassula ovata ‘Hobbit’. These succulents are distinguished by their unique tubular, finger-like leaves. Crassula ovata ‘Gollum’ has leaves that are almost entirely tubular with a flared, suction-cup-like tip. Crassula ovata ‘Hobbit’ has leaves that curl inwards, creating a spoon-shaped appearance. These shapes lead to common names like ‘Gollum Jade’, ‘Hobbit Jade’, ‘ET’s Fingers’, ‘Trumpet Jade’, or ‘Shrek Ears Plant’.
Other succulents might also be loosely called “green coral plant” due to their unusual forms. Examples include Crassula muscosa (Watch Chain Plant) with its moss-like foliage, or Euphorbia tirucalli (Pencil Cactus) which features slender, cylindrical stems.
Essential Care for Green Coral Plant
Light
Crassula ovata ‘Gollum’ and ‘Hobbit’ thrive in bright, indirect light. A south-facing or west-facing window is often ideal indoors. While they tolerate some direct morning sun, harsh afternoon sun can cause leaf scorch. Insufficient light may lead to leggy or stretched growth, also known as etiolation.
Watering
Watering is crucial for these succulents, as overwatering is a common issue. Use the “soak and dry” method: water thoroughly until it drains from the pot’s bottom, then allow the soil to dry completely before watering again. During the active growing season (spring and summer), more frequent watering may be necessary, perhaps every two to three weeks. During dormancy (fall and winter), reduce watering significantly, sometimes to once a month or less, as the plant’s water needs decrease.
Soil
These jade cultivars require a well-draining soil mix to prevent root rot. A specialized succulent or cactus potting mix is recommended. You can also create your own mix by amending standard potting soil with inorganic materials like perlite, pumice, or coarse sand to improve drainage and aeration. Good drainage ensures the soil does not retain excessive moisture, which can suffocate roots and lead to fungal issues.
Temperature and Humidity
Crassula ovata ‘Gollum’ and ‘Hobbit’ prefer average room temperatures, ranging from 65°F to 75°F (18°C to 24°C). They tolerate temperatures between 55°F and 80°F (13°C and 27°C) but need protection from extreme fluctuations and temperatures below 50°F (10°C). Normal indoor humidity levels are suitable, as these plants do not prefer high humidity.
Fertilizing
These jade plants are not heavy feeders and do not require frequent fertilization. During their active growing season (spring and summer), fertilize them no more than once a month. Use a balanced liquid succulent or general houseplant fertilizer diluted to half strength to avoid nutrient burn. Avoid fertilizing during fall and winter when the plant enters dormancy, as it will not actively utilize nutrients.
Propagating Green Coral Plant
Propagating Crassula ovata ‘Gollum’ or ‘Hobbit’ is straightforward, with stem cuttings being the most effective method. Take a healthy stem cutting at least three to five inches long, ensuring it has several leaves. Use clean, sharp tools to make a precise cut.
After taking the cutting, allow the cut end to callus over for a few days to a week. This step helps prevent rot when the cutting is planted. Once callused, plant the cutting in a pot filled with a well-draining succulent or cactus mix. Water sparingly until roots establish, then resume a regular watering schedule, ensuring the soil dries out between waterings. The ideal time for propagation is during the plant’s active growing season, typically in spring or early summer.
Troubleshooting Green Coral Plant Issues
Several common issues can affect Crassula ovata ‘Gollum’ or ‘Hobbit’, signaling a need for care adjustment. Shriveled or wrinkled leaves indicate underwatering; the plant needs a thorough soak until water drains from the bottom. Yellow, mushy leaves or leaf drop are signs of overwatering or root rot, requiring reduced watering and proper drainage.
Leggy or stretched growth (etiolation) points to insufficient light; move the plant to a brighter location. Pests like mealybugs, spider mites, and scale insects can infest these plants. Treat them by wiping with a cotton swab dipped in rubbing alcohol or applying insecticidal soap. A lack of growth might suggest dormancy, a need for nutrients, or that the plant has become root-bound, which may require repotting.
