Crassula ‘Blue Wave’ is a popular succulent known for its unique appearance and straightforward care. It offers a captivating aesthetic, adding visual interest to indoor and outdoor succulent arrangements. Its resilience allows it to thrive in various settings.
Unique Characteristics of Crassula ‘Blue Wave’
Crassula ‘Blue Wave’, a cultivar of Crassula arborescens indigenous to South Africa, is also known as Ripple Jade or Blue Waves Jade Plant. This succulent features attractive greenish-blue, undulating leaves resembling small waves, which gives the plant its common name. Its waxy leaves can develop soft red edges or a reddish tint when exposed to cooler temperatures or ample sunlight. It grows into a dense, shrubby form, reaching 2 to 4 feet tall and 1 to 3 feet wide.
Crassula ‘Blue Wave’ Care
Light
Crassula ‘Blue Wave’ thrives in bright, indirect light indoors, ideally near a sunny window. Too much direct sun, especially inland, can scald leaves or cause a reddish hue, while insufficient light may lead to stretching or color loss. Outdoors, it tolerates part shade inland and full sun along milder coasts.
Water
Crassula ‘Blue Wave’ is drought-tolerant and requires infrequent watering. Use the “soak and dry” method, allowing the soil to completely dry out between waterings to prevent root rot. During the active growing season (spring and summer), water thoroughly; reduce watering significantly in winter.
Soil
Well-draining soil is crucial for Crassula ‘Blue Wave’ to prevent root issues. A commercial cactus or succulent mix is suitable, or amend regular potting soil with perlite or sand for improved drainage. This plant prefers neutral to slightly acidic soil.
Temperature and Humidity
Crassula ‘Blue Wave’ prefers temperatures between 65-75°F (18-24°C). It is sensitive to frost; temperatures below 25-30°F (-3.9 to -1.1°C) can damage leaves, requiring protection in colder climates. The plant tolerates average household humidity, though it prefers lower humidity.
Fertilizer
Fertilizing Crassula ‘Blue Wave’ can support growth during the active season. Use a diluted succulent-specific fertilizer once a month from spring through summer. Over-fertilizing can harm the plant, as it is not a heavy feeder. Seaweed-based fertilizers are recommended for their microelements and biostimulants, which avoid excessive nitrogen.
Propagating Crassula ‘Blue Wave’
Crassula ‘Blue Wave’ is readily propagated from both stem and leaf cuttings. For stem cuttings, select a healthy segment and allow the cut end to callus for a few days to a week before planting. This callusing prevents rot. Insert the callused cutting into well-draining succulent or cactus soil.
When propagating from a leaf, gently remove a healthy leaf from the parent plant. Allow the leaf to callus for several days in a warm, dry spot. Lay the callused leaf on the surface of well-draining soil or lightly cover the cut end to encourage root development. Keep the soil lightly moist until roots form.
Troubleshooting Common Issues
Overwatering is a common problem, leading to mushy leaves, drooping stems, or root rot. A soft main trunk often indicates root rot; allow the plant to dry completely before rewatering. Underwatered plants may have wrinkled or soft leaves, signaling a need for hydration. Stretched leaves or color loss indicate insufficient light; move the plant to a brighter location. Crassula ‘Blue Wave’ is susceptible to pests like mealybugs, aphids, and spider mites. Regular inspection aids early detection, and infestations can be managed with natural remedies like neem oil or insecticidal soap.
