If grown outdoors, choose a location with partial shade to protect the plant from the harsh afternoon sun. It can also thrive in full sun, but be mindful of extreme heat. Using a grow lamp is recommended to provide adequate light for Cotyledon Orbiculata during the winter months, especially when natural sunlight is limited. Pay attention to how the plant responds to the artificial light. If you notice signs of stretching or discoloration, it might indicate that the light intensity or duration needs adjustment.
Cotyledon Orbiculata is adapted to arid conditions in its native habitat of South Africa, so like many succulents, it is drought-tolerant and does not need regular watering. The plant's thick, fleshy leaves are designed to minimize water loss through evaporation, helping it survive in dry environments. Only water when the topsoil is dry to the touch. Water thoroughly and let the excess water drain completely after each watering session to prevent root rot. Don’t forget to empty the saucer beneath the pot to avoid water accumulation. Be mindful of temperature conditions. In cooler months, the plant requires less water, so adjust your watering schedule accordingly.
Soil and Fertilizer
Use a well-draining soil mix specifically formulated for succulents or cacti. This type of soil prevents waterlogging, which is crucial for the health of Cotyledon Orbiculata. If you want to mix your soil, consider adding materials like perlite or coarse sand to general potting soil to enhance aeration and drainage. This helps prevent the soil from compacting, allowing the roots to breathe.
Cotyledon orbiculata doesn't require frequent or heavy fertilization. In fact, it's adapted to nutrient-poor soils. Fertilize sparingly to avoid over-fertilization, which can lead to issues. During the growing season (spring and summer), you can apply a balanced, diluted, liquid fertilizer every 4-6 weeks. Stop fertilization in the fall and winter when the plant's growth slows down. Always follow the specific recommendations on the fertilizer product you choose, and monitor the plant for any signs of stress, root burn or nutrient imbalances.
Temperature and Humidity
Cotyledon Orbiculata thrives in warm temperatures and can grow in most indoor environments with a temperature range of 65°F to 75°F. While it prefers warmth, it can tolerate cooler temperatures, especially if kept dry. However, it's important to protect the plant from frost, as freezing temperatures can damage its fleshy leaves. In winter, if temperatures drop significantly, especially outdoors, consider moving potted plants to a more sheltered location or protecting them from frost. Cotyledon Orbiculata can be grown outdoors in USDA hardiness zones 9b to 11b. In these zones, temperature in the winter usually ranges from 25°F to 50°F, if frost period is rare, the plant can be planted directly in the ground and may even thrive as a perennial. If your winter has regular temperature dips in winter, or if you live in regions with colder climates, planting Cotyledon Orbiculata in containers and moving it indoors during the cold days is recommended.
While this plant prefers warmth, it can tolerate cooler temperatures, especially if kept dry.
Cotyledon Orbiculata is adapted to arid conditions and has low humidity tolerance. It can thrive in areas with lower humidity levels. If grown indoors, the typical humidity levels found in most homes are generally well-tolerated by this succulent. Do not place this succulent in humid rooms (like the kitchen or bathroom). You can also open the doors regularly to have good airflow and to prevent stagnant air that would lead to mold and fungal issues.
Potting and Repotting
When potting, select a container that allows for some space for the plant to grow. Cotyledon Orbiculata prefers slightly snug conditions, so choose a pot that accommodates its current size with a little room to spare. To ensure the optimal health of your plant, it's crucial to plant it in a pot that prioritizes drainage, coupled with a well-draining soil. Choosing containers made of porous, breathable materials such as concrete, terracotta, or ceramic further enhances drainage and facilitates airflow around the roots. These materials contribute to a healthier root environment by preventing waterlogging and promoting essential oxygen exchange.
Incorporating soil aeration into your weekly plant care routine is a beneficial practice. Using a small shovel, delicately probe the plant's roots, creating small pockets of air within the soil. This method enhances the overall oxygen level in the soil, facilitating the efficient absorption of water, nutrients, and oxygen by the roots. Following this aeration, thoroughly water the soil, allowing it to drain completely, maintaining an optimal balance for the plant's well-being.
As a succulent, this plant is a slow grower and does not require annual repotting. Repotting every 2 or 3 years is generally sufficient. You should also repot when you observe crowded roots, the soil has become compacted, or if the plant's growth has slowed down despite appropriate care. When repotting, choose a pot that is one size larger than the current one. It's advisable to repot during the growing season.
During the repotting process, exercise caution to avoid breaking leaves or stems. Thoroughly inspect the plant for any signs of root rot or diseases.
Pruning is generally not required for succulents, as they are slow-growers. However, you should remove dead or damaged leaves, stems, or flowers to promote new growth. If your succulent becomes leggy, mostly due to inadequate lighting, you can also trim them back to promote a more compact and bushy appearance. It's generally best to prune during the active growing season to allow the plant enough time and energy to recover. Use only clean and sharp pruning tools to minimize damage.
As with many succulents, Cotyledon Orbiculata propagation is easy. It can be propagated through leaf cuttings or offsets.
For leaf cuttings, select healthy, mature leaves, allow the cut ends to dry and form a callus, then plant them in well-draining succulent soil. Water sparingly until roots develop, and once established, transplant the new plants into individual pots or the garden.
Alternatively, offsetscan be separated from the base of the parent plant, allowed to form a callus, and then planted in soil. Provide these new plants with lots of bright indirect light. Don’t forget to acclimate these baby plants before exposing them to direct sunlight.
Cotyledon orbiculata may produce eye-catching blooms typically in late summer. The plant sends up tall stems adorned with clusters of tubular, bell-shaped flowers. These flowers often exhibit shades of orange, coral, or red, adding a burst of color to the succulent's overall appearance. The flowering period is influenced by factors such as environmental conditions, sunlight exposure, and the overall health of the plant. Providing adequate sunlight and maintaining proper care can promote blooming, especially indoors. Once the blooming cycle is complete, spent flowers should be removed to encourage the plant to redirect energy into new growth.
