Caring for Your Cotyledon Orbiculata

Like most succulents, Cotyledon Orbiculata is relatively low maintenance and easy to care for, given the right conditions. Here are some simple care guidelines to ensure your plant thrives:


Cotyledon Orbiculata prefers to grow in full sun or partial shade. Make sure your plant receives about 6 hours of light daily. If growing indoors, choose a sunny location such as a south or west-facing window.


Drainage is crucial for the survival of this plant. Use a well-draining soil mix, like cactus or succulent potting mix, or create your own by adding coarse sand, perlite or pumice to regular potting soil.


Adopt a "soak and dry" watering method, allowing the soil to fully dry out between waterings. Be sure to reduce watering frequency during winter, as excess water can lead to root rot.


Cotyledon Orbiculata is cold hardy and can withstand temperatures down to USDA Zone 9 and 10 (20°F, -6.7°C). However, it is not frost-tolerant, so be sure to bring your plant indoors during harsh winter months.


Feed your plant during the active growth period (spring through summer) using a balanced, water-soluble fertilizer diluted to half strength every 3-4 weeks.

Propagation Techniques for Cotyledon Orbiculata

Cotyledon Orbiculata is easily propagated through several methods:

  • Leaf Cuttings: Gently remove a healthy leaf from the plant, let it callous over for a day or two, and then plant the cutting directly into a moist, well-draining soil mix.

  • Stem Cuttings: Cut a section of a stem, allow it to dry out and callous over for a few days and plant it in soil mix, ensuring a portion of the stem is below the soil surface.

  • Offsets: Mature Cotyledon Orbiculata plants will produce offsets or pups that can be separated from the parent plant and repotted.

Watch Out for Common Issues

Keep an eye out for some common problems associated with Cotyledon Orbiculata:

  • Pests: Aphids, mealybugs, spider mites, and scale insects may be attracted to your Cotyledon Orbiculata. Treat your plant with insecticidal soap or Neem oil.

  • Root Rot: Overwatering can lead to root rot. If you notice wilting, mushy leaves or a foul smell, remove the affected parts, let the plant dry and repot it in fresh, well-draining soil.

  • Sunburn: If your plant receives excessive direct sunlight, it may exhibit signs of sunburn, such as yellowing or browning of leaves. Move your plant to a shadier area or provide some shade during the hottest hours of the day.
