Crassula ovata obliqua, known as Spoon Jade or Obliqua Jade, is a popular succulent houseplant. A cultivar of the classic jade plant, it offers a distinctive aesthetic with its fleshy, spoon-shaped leaves and is favored for its low maintenance. This guide will help you cultivate a thriving Crassula ovata obliqua in your home.
Understanding Crassula Ovata Obliqua
Crassula ovata obliqua is a succulent shrub with thick, fleshy, green leaves and pointed tips. Its leaves are more elongated and upright than the common Crassula ovata. When exposed to direct sunlight, these glossy leaves can develop royal purple or reddish edges. The plant grows into an upright, multi-branching form, often reaching 1 to 6 feet, and can develop a stout, tree-like trunk over time. It produces small, star-shaped pink or white flowers in clusters from late winter to early spring.
Caring for Your Crassula Ovata Obliqua
Light Requirements
Crassula ovata obliqua thrives in bright, indirect light, ideally receiving at least six hours of sunlight daily. It tolerates some direct morning sun, but intense afternoon sun can lead to leaf scorch or sunburn. Indoors, a south-facing window is often suitable. Insufficient light can cause the plant to become leggy, while excessive direct sun may result in leaf scorch or brown spots.
Watering Practices
Proper watering is important for this succulent due to its susceptibility to overwatering and root rot. Use the “soak and dry” method: water thoroughly until it drains, then allow the soil to dry completely before rewatering. Check soil moisture by inserting a finger about an inch deep. Reduce watering in fall and winter when the plant enters a semi-dormant state. Overwatering can lead to mushy stems and yellowing leaves, while underwatering may cause leaves to shrivel or drop.
Soil and Potting
A well-draining soil mix is important for Crassula ovata obliqua to prevent waterlogging and root rot. Commercial succulent or cactus potting mixes are recommended as they contain ingredients like sand or perlite that facilitate drainage. If mixing your own, blend potting soil with coarse sand or perlite for improved aeration and drainage. The plant prefers a slightly acidic to neutral pH (6.0 to 7.0). Pots with drainage holes are also important to allow excess water to escape.
Temperature and Humidity
Crassula ovata obliqua thrives between 60 to 75 degrees Fahrenheit (15-24°C) during its active growing season. It tolerates typical household humidity, preferring low humidity environments. Protect the plant from frost, as temperatures below 30 degrees Fahrenheit (-1.1°C) can be lethal. Extreme cold or sudden temperature fluctuations can cause leaf drop or stress the plant.
Fertilization
Fertilization is not a strict requirement for Crassula ovata obliqua, as it is a slow-growing plant. However, it can benefit from a small amount of fertilizer during its active growth in spring and summer. Use a balanced, water-soluble fertilizer diluted to half strength, applying it every 4-6 weeks. Avoid fertilizing in fall and winter when growth slows or the plant enters dormancy, as over-fertilization can lead to salt buildup and damage.
Propagating Crassula Ovata Obliqua
Propagating Crassula ovata obliqua is straightforward using both leaf and stem cuttings. While a single leaf is the easiest way to start new plants, stem cuttings generally provide a faster path to a larger plant. Propagation is most successful at the beginning of the active growing period, in spring or summer.
Leaf Cuttings
For leaf cuttings, carefully remove a healthy, plump leaf from the stem. Allow the detached leaf to dry for several days, forming a callus over the cut end to prevent rot when planted. Once callused, place the leaf flat on top of well-draining succulent soil or insert the callused end slightly into the soil. Keep the soil lightly moist, not wet, and roots and small plantlets should begin to form within a few weeks.
Stem Cuttings
For stem cuttings, select a healthy stem segment about 3-4 inches long and use clean, sharp pruning shears to make the cut. Remove the lower leaves to expose a portion of the stem. Allow the cut end to callus for a few days, similar to leaf cuttings. After callusing, plant the stem cutting about an inch deep into well-draining succulent mix. Water lightly and maintain slight moisture in the soil until roots develop, which typically occurs within a few weeks.
Troubleshooting Common Issues
Common issues with Crassula ovata obliqua often signal a need for care adjustment. Mushy, yellowing leaves or a soft stem indicate overwatering and potential root rot; allow soil to dry completely and ensure drainage. Wrinkled, shriveled, or drooping leaves suggest underwatering; a thorough watering usually resolves this.
Leaf drop can result from overwatering, underwatering, sudden temperature changes, or insufficient light. Leggy growth is a sign of inadequate light; move the plant to a brighter location and prune stretched stems for more compact growth. Pests like mealybugs and spider mites can infest the plant, appearing as cotton-like masses or tiny specks. Manage these by wiping affected areas with rubbing alcohol or using insecticidal soap.
