Cultivation Methods
Senecio orbicularis Sond. ex Harv. is a perennial succulent plant that is native to South Africa. It can be grown indoors or outdoors in warm climates. When growing this plant, it's important to provide well-draining soil and access to plenty of sunlight.
Propagation can be done through stem cuttings or by dividing the plant. When propagating through stem cuttings, ensure the cutting is planted in a pot with well-draining soil, and it is slightly moist to encourage root development. Keep the soil moist, but not waterlogged, until the cutting has fully rooted.
Watering Needs
Senecio orbicularis Sond. ex Harv. is a drought-tolerant plant and can survive periods of neglect. However, it thrives best in soil that is kept slightly moist. When watering, ensure that the soil is fully soaked and that any excess water drains away. Avoid leaving the plant in standing water as this can lead to root rot.
During the growing season, water the plant every two weeks or when the soil is dry to the touch. During the dormant season, reduce watering to once a month or when the soil is completely dry.
Fertilization
Senecio orbicularis Sond. ex Harv. does not have high fertilization requirements. When fertilizing, ensure that a balanced fertilizer is used, either in granular or liquid form. Fertilize every two months during the growing season for the best results. Avoid fertilizing during the dormant season.

Senecio orbicularis Sond. ex Harv. can also be propagated by stem cuttings. The best time to take cuttings is during the summer months. Cut a 10-15cm long stem from the parent plant and remove the leaves from the lower 2/3 of the stem. Dip the cut end in rooting hormone and plant it in a pot filled with well-draining soil mix. Keep the soil moist and place the pot in a bright, warm spot. Roots will develop within 4-6 weeks.
Propagation by Division
This method of propagation involves dividing the parent plant into several sections. The best time to do this is during the spring or autumn. Dig up the plant carefully and separate the clumps, making sure each section has roots attached. Replant the sections in well-draining soil mix and keep them moist. Place the plants in a shady spot until they start to grow again.
With proper care and attention, Senecio orbicularis Sond. ex Harv. can be easily propagated through any of these methods. It's an excellent plant for both indoor and outdoor gardening.
