Watering needs for Ripple Jade
Ripple Jade is highly drought-tolerant, but it does best with regular watering during its growing season. For a 4-5 inch pot, bottom watering by immersing the container in water is recommended, allowing the soil to soak up moisture from the bottom.
Ensure that the soil dries out between waterings to prevent root rot. During winter, it’s important to water with caution, as cold, wet soil can cause the plant to lose its roots. Follow a proper watering technique to avoid overwatering, especially in colder months.
Light Requirements
Ripple Jade thrives in filtered sun but can tolerate partial shade. If placed in full sun, the leaves can develop a beautiful pinkish tinge.
However, it's important to acclimate the plant gradually if moving it from shade to full sun to prevent sunburn. Indoors, a bright, sunny window is ideal, but if light is limited, consider using a grow-light for indoor succulents to support its growth and maintain its vibrant appearance.
Fertilizing Schedule
Crassula arborescens undulatifolia benefits from light feeding during the growing season (spring to fall). For a 4-5 inch pot, use 1/4 teaspoon of a balanced, low-nitrogen cactus and succulent fertilizer, diluted to half strength.
Feed once or twice a season to promote healthy growth. Fertilizers rich in trace elements and micronutrients work best for this plant. To learn more about feeding succulents, refer to our fertilize guide for succulents.
Propagation Tips
Ripple Jade is very easy to propagate, making it a great option for those looking to expand their collection. It can be propagated from both stem and leaf cuttings.
Cuttings should be allowed to callous for a day or two before planting in well-draining, sandy soil. Alternatively, leaves can also be planted in soil where they will take root.

Advanced Care
- Soil Requirements: Ripple Jade grows best in sandy, gritty soil that allows for good drainage. This helps prevent the plant from becoming waterlogged, which can lead to root rot. If grown outdoors, choose a hot, dry area like a sunny patio or next to a swimming pool.
- Temperature Sensitivity: Ripple Jade is frost-sensitive and should be protected from frost to prevent scarring. While it can tolerate temperatures as low as -5°C for short periods in dry soil, it’s best to grow it in a greenhouse or conservatory if you live in a frost-prone area.
- Pest Management: Ripple Jade is relatively pest-resistant but may attract mealybugs or scale insects. Regularly check the plant for pests and treat infestations with neem oil or rubbing alcohol.
Unique Traits
Ripple Jade’s rippled, wavy leaves set it apart from other succulents, giving it a textured, sculptural appearance that makes it perfect for ornamental use. Its ability to thrive in containers or as a decorative garden plant makes it highly versatile.
In addition to its aesthetic value, Ripple Jade can be shaped into a bonsai, adding an element of artistry to any succulent arrangement. However, it's important to note that it is mildly toxic to pets if ingested.
